Imagine if you could record your life --
0
15260
4000
Zamislite da možete snimiti svoj život --
00:19
everything you said, everything you did,
1
19260
3000
sve što ste rekli, sve što ste učinili,
00:22
available in a perfect memory store at your fingertips,
2
22260
3000
dostupno savršeno pohranjeno, na dohvat ruke,
00:25
so you could go back
3
25260
2000
tako da se možete vratiti,
00:27
and find memorable moments and relive them,
4
27260
3000
pronaći značajne trenutke i ponovno ih proživjeti,
00:30
or sift through traces of time
5
30260
3000
ili preletjeti kroz tragove vremena
00:33
and discover patterns in your own life
6
33260
2000
i otkriti uzorke u vlastitom životu
00:35
that previously had gone undiscovered.
7
35260
3000
koje ranije niste ni primijetili.
00:38
Well that's exactly the journey
8
38260
2000
Točno je na takvo putovanje
00:40
that my family began
9
40260
2000
krenula moja obitelj
00:42
five and a half years ago.
10
42260
2000
prije pet i pol godina.
00:44
This is my wife and collaborator, Rupal.
11
44260
3000
Ovo je moja supruga i suradnica, Rupal.
00:47
And on this day, at this moment,
12
47260
2000
Ovog smo dana i u ovom trenutku
00:49
we walked into the house with our first child,
13
49260
2000
ušli u kuću s našim prvim djetetom,
00:51
our beautiful baby boy.
14
51260
2000
našim prekrasnim sinom.
00:53
And we walked into a house
15
53260
3000
Ušli smo u kuću
00:56
with a very special home video recording system.
16
56260
4000
s vrlo posebnim sustavom za kućno snimanje.
01:07
(Video) Man: Okay.
17
67260
2000
(Video) Muškarac: U redu.
01:10
Deb Roy: This moment
18
70260
1000
Deb Roy: Taj trenutak
01:11
and thousands of other moments special for us
19
71260
3000
i tisuće drugih posebnih trenutaka
01:14
were captured in our home
20
74260
2000
zabilježeni su u našem domu
01:16
because in every room in the house,
21
76260
2000
jer u svakoj sobi u našoj kući,
01:18
if you looked up, you'd see a camera and a microphone,
22
78260
3000
ako biste podigli pogled, vidjeli biste kameru i mikrofon,
01:21
and if you looked down,
23
81260
2000
a ako biste pogledali prema dolje,
01:23
you'd get this bird's-eye view of the room.
24
83260
2000
dobili biste ptičju perspektivu sobe.
01:25
Here's our living room,
25
85260
3000
Ovo je naša dnevna soba,
01:28
the baby bedroom,
26
88260
3000
dječja soba,
01:31
kitchen, dining room
27
91260
2000
kuhinja, blagovaonica,
01:33
and the rest of the house.
28
93260
2000
i ostatak kuće.
01:35
And all of these fed into a disc array
29
95260
3000
Sve se to spremalo na niz diskova
01:38
that was designed for a continuous capture.
30
98260
3000
izrađenih za trajno snimanje.
01:41
So here we are flying through a day in our home
31
101260
3000
Sada ubrzano gledamo jedan dan u našem domu.
01:44
as we move from sunlit morning
32
104260
3000
Krećemo od sunčanog jutra
01:47
through incandescent evening
33
107260
2000
preko osvijetljene večeri
01:49
and, finally, lights out for the day.
34
109260
3000
i na kraju gasimo svjetla.
01:53
Over the course of three years,
35
113260
3000
Tijekom tri godine
01:56
we recorded eight to 10 hours a day,
36
116260
2000
snimali smo 8 do 10 sati na dan,
01:58
amassing roughly a quarter-million hours
37
118260
3000
što na kraju čini oko četvrt milijuna sati
02:01
of multi-track audio and video.
38
121260
3000
paralelno snimanog audio i video materijala.
02:04
So you're looking at a piece of what is by far
39
124260
2000
Dakle, gledate dio daleko najveće
02:06
the largest home video collection ever made.
40
126260
2000
kolekcije kućnih videa ikad napravljene.
02:08
(Laughter)
41
128260
3000
(Smijeh)
02:11
And what this data represents
42
131260
2000
Ono što ovi podaci predstavljaju
02:13
for our family at a personal level,
43
133260
4000
našoj obitelji na osobnoj razini,
02:17
the impact has already been immense,
44
137260
2000
utjecaj je već do sada ogroman,
02:19
and we're still learning its value.
45
139260
3000
i još uvijek otkrivamo njihovu vrijednost.
02:22
Countless moments
46
142260
2000
Bezbrojni trenuci
02:24
of unsolicited natural moments, not posed moments,
47
144260
3000
neglumljenih prirodnih trenutaka, nenamještenih,
02:27
are captured there,
48
147260
2000
ovdje su zabilježeni,
02:29
and we're starting to learn how to discover them and find them.
49
149260
3000
i polako ih učimo otkrivati i tražiti.
02:32
But there's also a scientific reason that drove this project,
50
152260
3000
Ali postoji i znanstveni razlog za ovaj projekt,
02:35
which was to use this natural longitudinal data
51
155260
4000
a to je da upotrijebimo ove prirodne linearne podatke
02:39
to understand the process
52
159260
2000
kako bismo shvatili proces
02:41
of how a child learns language --
53
161260
2000
kojim dijete uči jezik --
02:43
that child being my son.
54
163260
2000
a to dijete je moj sin.
02:45
And so with many privacy provisions put in place
55
165260
4000
I tako, s mnogim ograničenjima zbog privatnosti,
02:49
to protect everyone who was recorded in the data,
56
169260
3000
kako bismo zaštitili sve koji su snimljeni,
02:52
we made elements of the data available
57
172260
3000
učinili smo dijelove podataka dostupnima
02:55
to my trusted research team at MIT
58
175260
3000
mojem istraživačkom timu na MIT-u
02:58
so we could start teasing apart patterns
59
178260
3000
kako bismo mogli početi izdvajati uzorke
03:01
in this massive data set,
60
181260
3000
u tom ogromnom skupu podataka,
03:04
trying to understand the influence of social environments
61
184260
3000
pokušavajući shvatiti utjecaj društvene sredine
03:07
on language acquisition.
62
187260
2000
na usvajanje jezika.
03:09
So we're looking here
63
189260
2000
Sada gledamo
03:11
at one of the first things we started to do.
64
191260
2000
jednu od prvih stvari koje smo počeli raditi.
03:13
This is my wife and I cooking breakfast in the kitchen,
65
193260
4000
Ovdje moja supruga i ja spremamo doručak u kuhinji.
03:17
and as we move through space and through time,
66
197260
3000
Kako se krećemo kroz prostor i vrijeme,
03:20
a very everyday pattern of life in the kitchen.
67
200260
3000
svakodnevni uzorak života u kuhinji.
03:23
In order to convert
68
203260
2000
Kako bismo pretvorili
03:25
this opaque, 90,000 hours of video
69
205260
3000
ovih mutnih 90.000 sati snimaka
03:28
into something that we could start to see,
70
208260
2000
u nešto što možemo jasno vidjeti,
03:30
we use motion analysis to pull out,
71
210260
2000
koristimo analizu pokreta kako bismo izvukli,
03:32
as we move through space and through time,
72
212260
2000
dok se krećemo kroz prostor i vrijeme,
03:34
what we call space-time worms.
73
214260
3000
ono što zovemo prostorno-vremenskim crvima.
03:37
And this has become part of our toolkit
74
217260
3000
I to je postao dio našeg alata
03:40
for being able to look and see
75
220260
3000
koji smo koristili kako bismo vidjeli
03:43
where the activities are in the data,
76
223260
2000
gdje se aktivnosti nalaze u podacima,
03:45
and with it, trace the pattern of, in particular,
77
225260
3000
i njima pratimo uzorke, konkretno,
03:48
where my son moved throughout the home,
78
228260
2000
kuda se moj sin kretao kroz kuću,
03:50
so that we could focus our transcription efforts,
79
230260
3000
kako bismo mogli rad na transkriptima
03:53
all of the speech environment around my son --
80
233260
3000
i govornu okolinu mogli usredotočiti na mojeg sina --
03:56
all of the words that he heard from myself, my wife, our nanny,
81
236260
3000
sve riječi koje je čuo od mene, moje supruge, naše dadilje,
03:59
and over time, the words he began to produce.
82
239260
3000
i, s vremenom, na riječi koje je počeo izgovarati.
04:02
So with that technology and that data
83
242260
3000
S tom tehnologijom i tim podacima
04:05
and the ability to, with machine assistance,
84
245260
2000
i s mogućnošću da
04:07
transcribe speech,
85
247260
2000
uz pomoć strojeva transkribiramo govor,
04:09
we've now transcribed
86
249260
2000
do sada smo transkribirali
04:11
well over seven million words of our home transcripts.
87
251260
3000
više od sedam milijuna riječi s naših kućnih transkripata.
04:14
And with that, let me take you now
88
254260
2000
S tim na umu, sad ću vam predstaviti
04:16
for a first tour into the data.
89
256260
3000
prvi pregled podataka.
04:19
So you've all, I'm sure,
90
259260
2000
Svi ste, siguran sam,
04:21
seen time-lapse videos
91
261260
2000
vidjeli ubrzane videosnimke,
04:23
where a flower will blossom as you accelerate time.
92
263260
3000
na kojima je ubrzano prikazan cvat cvijeta.
04:26
I'd like you to now experience
93
266260
2000
Sada bih vam volio dočarati
04:28
the blossoming of a speech form.
94
268260
2000
cvat govornog oblika.
04:30
My son, soon after his first birthday,
95
270260
2000
Moj sin je, nedugo nakon prvog rođendana,
04:32
would say "gaga" to mean water.
96
272260
3000
govorio "gaga", što je značilo "voda".
04:35
And over the course of the next half-year,
97
275260
3000
Tijekom narednih pola godine
04:38
he slowly learned to approximate
98
278260
2000
polako se približavao
04:40
the proper adult form, "water."
99
280260
3000
ispravnom obliku koji koriste odrasli, "voda".
04:43
So we're going to cruise through half a year
100
283260
2000
Sad ćemo proletjeti kroz pola godine
04:45
in about 40 seconds.
101
285260
2000
u otprilike 40 sekundi.
04:47
No video here,
102
287260
2000
Ovdje nema videozapisa,
04:49
so you can focus on the sound, the acoustics,
103
289260
3000
tako da se možete usredotočiti na zvuk, na akustiku
04:52
of a new kind of trajectory:
104
292260
2000
nove vrste putanje:
04:54
gaga to water.
105
294260
2000
od "gaga" do vode.
04:56
(Audio) Baby: Gagagagagaga
106
296260
12000
(Zvuk) Dijete: Gagagagagaga
05:08
Gaga gaga gaga
107
308260
4000
Gaga gaga gaga
05:12
guga guga guga
108
312260
5000

05:17

109

voda voda voda
05:35

113
335260
4000
voda voda
05:39
water.
114
339260
2000
voda.
05:41
DR: He sure nailed it, didn't he.
115
341260
2000
DR: Odlično je to svladao, za ne?
05:43
(Applause)
116
343260
7000
(Pljesak)
05:50
So he didn't just learn water.
117
350260
2000
I nije naučio samo vodu.
05:52
Over the course of the 24 months,
118
352260
2000
Tijekom 24 mjeseca,
05:54
the first two years that we really focused on,
119
354260
3000
prve dvije godine, na koje smo se najviše usredotočili,
05:57
this is a map of every word he learned in chronological order.
120
357260
4000
ovo je prikaz svih riječi koje je naučio, kronološkim redom.
06:01
And because we have full transcripts,
121
361260
3000
A budući da imamo potpune transkripte,
06:04
we've identified each of the 503 words
122
364260
2000
identificirali smo svaku od 503 riječi
06:06
that he learned to produce by his second birthday.
123
366260
2000
koje je naučio do drugog rođendana.
06:08
He was an early talker.
124
368260
2000
Rano je progovorio.
06:10
And so we started to analyze why.
125
370260
3000
I počeli smo analizirati zašto.
06:13
Why were certain words born before others?
126
373260
3000
Zašto su se neke riječi "rodile" prije drugih?
06:16
This is one of the first results
127
376260
2000
Ovo je jedan od prvih rezultata koje smo dobili
06:18
that came out of our study a little over a year ago
128
378260
2000
iz našeg istraživanja prije nešto više od godinu dana
06:20
that really surprised us.
129
380260
2000
i koji nas je zaista iznenadio.
06:22
The way to interpret this apparently simple graph
130
382260
3000
Na ovom naizgled jednostavnom grafu
06:25
is, on the vertical is an indication
131
385260
2000
na okomitoj osi prikazana je kompleksnost
06:27
of how complex caregiver utterances are
132
387260
3000
rečenica koje su izgovarali odrasli,
06:30
based on the length of utterances.
133
390260
2000
a temeljeno na dužini rečenica.
06:32
And the [horizontal] axis is time.
134
392260
3000
A na horizontalnoj osi je vrijeme.
06:35
And all of the data,
135
395260
2000
I sve smo podatke
06:37
we aligned based on the following idea:
136
397260
3000
poredali prema sljedećem principu:
06:40
Every time my son would learn a word,
137
400260
3000
svaki put kad bi moj sin naučio riječ,
06:43
we would trace back and look at all of the language he heard
138
403260
3000
pratili bismo podatke unatrag i gledali sav govor koji je čuo
06:46
that contained that word.
139
406260
2000
i koji je sadržavao tu riječ
06:48
And we would plot the relative length of the utterances.
140
408260
4000
i ucrtali bismo relativnu duljinu tih rečenica.
06:52
And what we found was this curious phenomena,
141
412260
3000
Tako smo otkrili ovaj zanimljiv fenomen:
06:55
that caregiver speech would systematically dip to a minimum,
142
415260
3000
govor odrasle osobe sustavno se svodio na minimum,
06:58
making language as simple as possible,
143
418260
3000
čineći govor što jednostavnijim,
07:01
and then slowly ascend back up in complexity.
144
421260
3000
a zatim bi ponovno postupno postao sve složeniji.
07:04
And the amazing thing was
145
424260
2000
Ono što nas je zadivilo
07:06
that bounce, that dip,
146
426260
2000
bio je taj pad, to pojednostavljenje,
07:08
lined up almost precisely
147
428260
2000
koje se gotovo potpuno poklapa
07:10
with when each word was born --
148
430260
2000
s trenutkom "rođenja" svake riječi --
07:12
word after word, systematically.
149
432260
2000
i tako sustavno, za svaku riječ.
07:14
So it appears that all three primary caregivers --
150
434260
2000
Tako izgleda da su sva tri primarna skrbnika --
07:16
myself, my wife and our nanny --
151
436260
3000
ja, moja supruga i naša dadilja --
07:19
were systematically and, I would think, subconsciously
152
439260
3000
sustavno i, rekao bih, podsvjesno,
07:22
restructuring our language
153
442260
2000
rekonstruirala jezik
07:24
to meet him at the birth of a word
154
444260
3000
kako bi se susreli s njim prilikom rođenja riječi
07:27
and bring him gently into more complex language.
155
447260
4000
i nježno ga uveli u složeniji govor.
07:31
And the implications of this -- there are many,
156
451260
2000
Pretpostavka je sljedeća -- ima ih više,
07:33
but one I just want to point out,
157
453260
2000
ali ovu želim istaknuti:
07:35
is that there must be amazing feedback loops.
158
455260
3000
postoje zadivljujuće petlje povratnih informacija.
07:38
Of course, my son is learning
159
458260
2000
Naravno, moj sin uči
07:40
from his linguistic environment,
160
460260
2000
od svoje jezične okoline,
07:42
but the environment is learning from him.
161
462260
3000
ali i okolina uči od njega.
07:45
That environment, people, are in these tight feedback loops
162
465260
3000
Ta okolina, ljudi, dio su petlji povratnih informacija
07:48
and creating a kind of scaffolding
163
468260
2000
i grade neku vrstu skele
07:50
that has not been noticed until now.
164
470260
3000
koja do sad još nije bila uočena.
07:54
But that's looking at the speech context.
165
474260
2000
Ali to se odnosi samo na govorni kontekst.
07:56
What about the visual context?
166
476260
2000
Što je s vizualnim kontekstom?
07:58
We're not looking at --
167
478260
2000
Sad gledamo --
08:00
think of this as a dollhouse cutaway of our house.
168
480260
2000
zamislite ovo kao presjek naše kuće, poput kućice za lutke.
08:02
We've taken those circular fish-eye lens cameras,
169
482260
3000
Uzeli smo kružne leće u obliku ribljeg oka
08:05
and we've done some optical correction,
170
485260
2000
i napravili smo neke optičke korekcije,
08:07
and then we can bring it into three-dimensional life.
171
487260
4000
nakon čega smo mogli stvoriti stvaran trodimenzionalni prikaz.
08:11
So welcome to my home.
172
491260
2000
Pa, dobrodošli u moj dom.
08:13
This is a moment,
173
493260
2000
Ovo je trenutak,
08:15
one moment captured across multiple cameras.
174
495260
3000
jedan trenutak zabilježen na više kamera.
08:18
The reason we did this is to create the ultimate memory machine,
175
498260
3000
Razlog zbog kojeg smo to učinili jest da bismo stvorili najbolji memorijski stroj,
08:21
where you can go back and interactively fly around
176
501260
3000
u kojem se možete vraćati i interaktivno se kretati
08:24
and then breathe video-life into this system.
177
504260
3000
i zatim udahnuti život ovom sustavu.
08:27
What I'm going to do
178
507260
2000
Sada ću vam prikazati
08:29
is give you an accelerated view of 30 minutes,
179
509260
3000
ubrzan pregled 30 minuta
08:32
again, of just life in the living room.
180
512260
2000
svakodnevnog života u dnevnom boravku.
08:34
That's me and my son on the floor.
181
514260
3000
To smo ja i moj sin na podu.
08:37
And there's video analytics
182
517260
2000
A ovo su videoanalize
08:39
that are tracking our movements.
183
519260
2000
koje prate naše pokrete.
08:41
My son is leaving red ink. I am leaving green ink.
184
521260
3000
Moj sin ostavlja crveni trag, a ja ostavljam zeleni trag.
08:44
We're now on the couch,
185
524260
2000
Sad smo na kauču,
08:46
looking out through the window at cars passing by.
186
526260
3000
gledamo kroz prozor automobile koji prolaze.
08:49
And finally, my son playing in a walking toy by himself.
187
529260
3000
I na kraju, moj sin se sam igra u hodalici.
08:52
Now we freeze the action, 30 minutes,
188
532260
3000
Sad zamrznemo snimku, 30 minuta,
08:55
we turn time into the vertical axis,
189
535260
2000
prikažemo vrijeme na okomitoj osi,
08:57
and we open up for a view
190
537260
2000
i dobivamo pregled
08:59
of these interaction traces we've just left behind.
191
539260
3000
interaktivnih tragova koje smo ostavljali.
09:02
And we see these amazing structures --
192
542260
3000
Vidimo te zadivljujuće strukture --
09:05
these little knots of two colors of thread
193
545260
3000
te male čvorove dviju boja,
09:08
we call "social hot spots."
194
548260
2000
koje nazivamo društvenim žarištima.
09:10
The spiral thread
195
550260
2000
Spiralni trag
09:12
we call a "solo hot spot."
196
552260
2000
nazivamo samostalnim žarištem.
09:14
And we think that these affect the way language is learned.
197
554260
3000
Mislimo da to utječe na način na koji se uči jezik.
09:17
What we'd like to do
198
557260
2000
Htjeli bismo
09:19
is start understanding
199
559260
2000
početi shvaćati
09:21
the interaction between these patterns
200
561260
2000
interakciju između ovih uzoraka
09:23
and the language that my son is exposed to
201
563260
2000
i govora kojem je moj sin izložen
09:25
to see if we can predict
202
565260
2000
kako bismo pokušali predvidjeti
09:27
how the structure of when words are heard
203
567260
2000
kako struktura vremena u kojem se riječi čuju
09:29
affects when they're learned --
204
569260
2000
utječe na vrijeme u kojem se nauče --
09:31
so in other words, the relationship
205
571260
2000
odnosno, drugim riječima, vezu
09:33
between words and what they're about in the world.
206
573260
4000
između riječi i onoga što one znače u svijetu.
09:37
So here's how we're approaching this.
207
577260
2000
Evo kako mi pristupamo tome.
09:39
In this video,
208
579260
2000
U ovom videu,
09:41
again, my son is being traced out.
209
581260
2000
ponovno, pratimo mog sina.
09:43
He's leaving red ink behind.
210
583260
2000
On ostavlja crveni trag.
09:45
And there's our nanny by the door.
211
585260
2000
Ovo je naša dadilja, pored vrata.
09:47
(Video) Nanny: You want water? (Baby: Aaaa.)
212
587260
3000
(Video) Dadilja: Hoćeš vode? (Dijete: Aaaa.)
09:50
Nanny: All right. (Baby: Aaaa.)
213
590260
3000
Dadilja: U redu. (Dijete: Aaaa.)
09:53
DR: She offers water,
214
593260
2000
DR: Ona nudi vodu,
09:55
and off go the two worms
215
595260
2000
i dva crva odlaze
09:57
over to the kitchen to get water.
216
597260
2000
u kuhinju po vodu.
09:59
And what we've done is use the word "water"
217
599260
2000
Upotrijebili smo riječ "voda"
10:01
to tag that moment, that bit of activity.
218
601260
2000
da bismo označili taj trenutak, taj dio aktivnosti.
10:03
And now we take the power of data
219
603260
2000
A sada koristimo moć podataka
10:05
and take every time my son
220
605260
3000
i dobivamo svaki trenutak kad je moj sin
10:08
ever heard the word water
221
608260
2000
čuo riječ voda
10:10
and the context he saw it in,
222
610260
2000
i kontekst u kojem ju je vidio.
10:12
and we use it to penetrate through the video
223
612260
3000
Koristimo to kako bismo prošli kroz video
10:15
and find every activity trace
224
615260
3000
i pronašli svaki trag aktivnosti
10:18
that co-occurred with an instance of water.
225
618260
3000
koja se pojavila u istom trenutku kad i voda.
10:21
And what this data leaves in its wake
226
621260
2000
Ono što je nastalo kao posljedica tih podataka
10:23
is a landscape.
227
623260
2000
jest krajolik.
10:25
We call these wordscapes.
228
625260
2000
Ovo nazivamo "rječolikom".
10:27
This is the wordscape for the word water,
229
627260
2000
Ovo je rječolik za riječ voda,
10:29
and you can see most of the action is in the kitchen.
230
629260
2000
i možete vidjeti da je većina aktivnosti u kuhinji.♫
10:31
That's where those big peaks are over to the left.
231
631260
3000
Tu se nalaze ovi veliki vrhovi s lijeve strane.
10:34
And just for contrast, we can do this with any word.
232
634260
3000
Samo za usporedbu, tako možemo prikazati svaku riječ.
10:37
We can take the word "bye"
233
637260
2000
Možemo uzeti riječ "đenja",
10:39
as in "good bye."
234
639260
2000
kao u "do viđenja".
10:41
And we're now zoomed in over the entrance to the house.
235
641260
2000
I sad smo prebačeni pred ulaz u kuću.
10:43
And we look, and we find, as you would expect,
236
643260
3000
Otkrivamo, kao što bi se i očekivalo,
10:46
a contrast in the landscape
237
646260
2000
da postoji razlika u krajoliku,
10:48
where the word "bye" occurs much more in a structured way.
238
648260
3000
pri čemu se riječ "đenja" pojavljuje mnogo pravilnije.
10:51
So we're using these structures
239
651260
2000
Dakle, koristimo te strukture
10:53
to start predicting
240
653260
2000
kako bismo počeli predviđati
10:55
the order of language acquisition,
241
655260
3000
redoslijed usvajanja jezika,
10:58
and that's ongoing work now.
242
658260
2000
i još uvijek radimo na tome.
11:00
In my lab, which we're peering into now, at MIT --
243
660260
3000
U mojem laboratoriju na MIT-u, koji sada gledamo --
11:03
this is at the media lab.
244
663260
2000
ovo je u medijskom laboratoriju.
11:05
This has become my favorite way
245
665260
2000
Ovo je postao moj omiljeni način
11:07
of videographing just about any space.
246
667260
2000
grafičkog videoprikaza svakog prostora.
11:09
Three of the key people in this project,
247
669260
2000
Troje ključnih ljudi u ovom projektu,
11:11
Philip DeCamp, Rony Kubat and Brandon Roy are pictured here.
248
671260
3000
Philip DeCamp, Rony Kubat i Brandon Roy prikazani su ovdje.
11:14
Philip has been a close collaborator
249
674260
2000
Philip mi je bio bliski suradnik
11:16
on all the visualizations you're seeing.
250
676260
2000
pri izradi vizualizacija koje gledate.
11:18
And Michael Fleischman
251
678260
3000
A Michael Fleischman
11:21
was another Ph.D. student in my lab
252
681260
2000
također je bio student na doktoratu u mojem laboratoriju
11:23
who worked with me on this home video analysis,
253
683260
3000
koji je sa mnom radio na ovoj analizi kućnog videa,
11:26
and he made the following observation:
254
686260
3000
i on je primijetio sljedeće:
11:29
that "just the way that we're analyzing
255
689260
2000
"način na koji analiziramo
11:31
how language connects to events
256
691260
3000
kako je jezik povezan s događajima
11:34
which provide common ground for language,
257
694260
2000
koji predstavljaju zajednički temelj jezika,
11:36
that same idea we can take out of your home, Deb,
258
696260
4000
tu istu ideju možemo primijeniti i izvan tvoje kuće, Deb,
11:40
and we can apply it to the world of public media."
259
700260
3000
i možemo je primijeniti na svijet javnih medija."
11:43
And so our effort took an unexpected turn.
260
703260
3000
I tako je naš rad krenuo u neočekivanom smjeru.
11:46
Think of mass media
261
706260
2000
Zamislite kako masovni mediji
11:48
as providing common ground
262
708260
2000
tvore zajednički temelj,
11:50
and you have the recipe
263
710260
2000
a vi imate recept
11:52
for taking this idea to a whole new place.
264
712260
3000
kako tu ideju prenijeti na neku višu razinu.
11:55
We've started analyzing television content
265
715260
3000
Počeli smo analizirati televizijski sadržaj
11:58
using the same principles --
266
718260
2000
koristeći iste principe --
12:00
analyzing event structure of a TV signal --
267
720260
3000
analizu strukture događaja TV signala --
12:03
episodes of shows,
268
723260
2000
epizode emisija,
12:05
commercials,
269
725260
2000
reklame,
12:07
all of the components that make up the event structure.
270
727260
3000
sve sastavnice koje čine strukturu događaja.
12:10
And we're now, with satellite dishes, pulling and analyzing
271
730260
3000
Sada, pomoću satelitskih tanjura, skupljamo i analiziramo
12:13
a good part of all the TV being watched in the United States.
272
733260
3000
dobar dio cjelokupnog TV programa koji se gleda u SAD-u.
12:16
And you don't have to now go and instrument living rooms with microphones
273
736260
3000
I sad ne trebate opremati dnevne boravke mikrofonima
12:19
to get people's conversations,
274
739260
2000
da biste čuli razgovore drugih ljudi,
12:21
you just tune into publicly available social media feeds.
275
741260
3000
samo se uključite u javno dostupne društvene medije.
12:24
So we're pulling in
276
744260
2000
Tako da prikupljamo
12:26
about three billion comments a month,
277
746260
2000
oko tri milijuna komentara mjesečno.
12:28
and then the magic happens.
278
748260
2000
I tada se događa čarolija.
12:30
You have the event structure,
279
750260
2000
Imate strukturu događaja,
12:32
the common ground that the words are about,
280
752260
2000
zajedničku točku svih riječi
12:34
coming out of the television feeds;
281
754260
3000
koje dolaze iz televizijskih emisija;
12:37
you've got the conversations
282
757260
2000
Imate razgovore
12:39
that are about those topics;
283
759260
2000
koji su o tim temama;
12:41
and through semantic analysis --
284
761260
3000
i kroz semantičku analizu --
12:44
and this is actually real data you're looking at
285
764260
2000
sad gledate prave, stvarne podatke
12:46
from our data processing --
286
766260
2000
iz naše obrade podataka --
12:48
each yellow line is showing a link being made
287
768260
3000
svaka žuta linija označuje vezu koja se stvara
12:51
between a comment in the wild
288
771260
3000
između nevezanog komentara
12:54
and a piece of event structure coming out of the television signal.
289
774260
3000
i dijela strukture događaja koja dolazi iz televizijskog signala.
12:57
And the same idea now
290
777260
2000
I ta se ista ideja
12:59
can be built up.
291
779260
2000
sad može nadograditi.
13:01
And we get this wordscape,
292
781260
2000
Tako da dobivamo ovaj rječolik,
13:03
except now words are not assembled in my living room.
293
783260
3000
osim što riječi sada nisu složene u mojem dnevnom boravku.
13:06
Instead, the context, the common ground activities,
294
786260
4000
Umjesto toga, kontekst, zajedničke aktivnosti,
13:10
are the content on television that's driving the conversations.
295
790260
3000
sadržaj su na televiziji koji stvara razgovore.
13:13
And what we're seeing here, these skyscrapers now,
296
793260
3000
Ovo što ovdje vidimo, ovi neboderi,
13:16
are commentary
297
796260
2000
jesu komentari
13:18
that are linked to content on television.
298
798260
2000
koji su povezani s televizijskim sadržajem.
13:20
Same concept,
299
800260
2000
Isti koncept,
13:22
but looking at communication dynamics
300
802260
2000
osim što se gleda dinamika komunikacije
13:24
in a very different sphere.
301
804260
2000
u vrlo različitoj sferi.
13:26
And so fundamentally, rather than, for example,
302
806260
2000
Tako da, u biti, umjesto da, primjerice
13:28
measuring content based on how many people are watching,
303
808260
3000
mjerimo sadržaj na temelju broja gledatelja,
13:31
this gives us the basic data
304
811260
2000
ovo nam daje osnovne podatke
13:33
for looking at engagement properties of content.
305
813260
3000
za razumijevanje poticajnih svojstava sadržaja.
13:36
And just like we can look at feedback cycles
306
816260
3000
I baš kao što možemo gledati povratne cikluse
13:39
and dynamics in a family,
307
819260
3000
i dinamiku u obitelji,
13:42
we can now open up the same concepts
308
822260
3000
sad možemo proširiti iste koncepte
13:45
and look at much larger groups of people.
309
825260
3000
i obrađivati mnogo veće grupe ljudi.
13:48
This is a subset of data from our database --
310
828260
3000
Ovo je podskup podataka iz naše baze --
13:51
just 50,000 out of several million --
311
831260
3000
samo 50.000 od nekoliko milijuna --
13:54
and the social graph that connects them
312
834260
2000
i društveni graf koji ih povezuje
13:56
through publicly available sources.
313
836260
3000
kroz javno dostupne izvore.
13:59
And if you put them on one plain,
314
839260
2000
Ako ih stavite u jednu ravninu,
14:01
a second plain is where the content lives.
315
841260
3000
na drugoj ravnini nalazi se sadržaj.
14:04
So we have the programs
316
844260
3000
Tako imamo programe
14:07
and the sporting events
317
847260
2000
i sportske događaje
14:09
and the commercials,
318
849260
2000
i reklame
14:11
and all of the link structures that tie them together
319
851260
2000
a sve strukture povezivanja koje ih međusobno vežu
14:13
make a content graph.
320
853260
2000
zajedno čine graf sadržaja.
14:15
And then the important third dimension.
321
855260
4000
I sada, važna treća dimenzija.
14:19
Each of the links that you're seeing rendered here
322
859260
2000
Svaka od poveznica koje ovdje vidite prikazane
14:21
is an actual connection made
323
861260
2000
stvarna je veza koja je nastala
14:23
between something someone said
324
863260
3000
između nečega što je netko rekao
14:26
and a piece of content.
325
866260
2000
i dijela sadržaja.
14:28
And there are, again, now tens of millions of these links
326
868260
3000
A sada ponovno vidimo desetke milijuna tih poveznica
14:31
that give us the connective tissue of social graphs
327
871260
3000
koje sačinjavaju vezivno tkivo društvenih grafova
14:34
and how they relate to content.
328
874260
3000
i načina na koji su povezani sa sadržajem.
14:37
And we can now start to probe the structure
329
877260
2000
Sad možemo početi ispitivati strukturu
14:39
in interesting ways.
330
879260
2000
na zanimljive načine.
14:41
So if we, for example, trace the path
331
881260
3000
Ako, primjerice, pratimo put
14:44
of one piece of content
332
884260
2000
jednog dijela sadržaja
14:46
that drives someone to comment on it,
333
886260
2000
koji potiče nekoga da ga komentira,
14:48
and then we follow where that comment goes,
334
888260
3000
i zatim slijedimo put kojim taj komentar ide,
14:51
and then look at the entire social graph that becomes activated
335
891260
3000
i zatim pogledamo cijeli društveni graf koji se aktivira
14:54
and then trace back to see the relationship
336
894260
3000
i zatim se vratimo kako bismo vidjeli odnos
14:57
between that social graph and content,
337
897260
2000
između tog društvenog grafa i sadržaja,
14:59
a very interesting structure becomes visible.
338
899260
2000
pojavljuje se vrlo zanimljiva struktura.
15:01
We call this a co-viewing clique,
339
901260
2000
To zovemo ekipom za zajedničko promatranje,
15:03
a virtual living room if you will.
340
903260
3000
virtualni dnevni boravak.
15:06
And there are fascinating dynamics at play.
341
906260
2000
Odvija se fascinantna dinamika.
15:08
It's not one way.
342
908260
2000
I to nije jednosmjerno.
15:10
A piece of content, an event, causes someone to talk.
343
910260
3000
Dio sadržaja, neki događaj, potakne nekoga da govori.
15:13
They talk to other people.
344
913260
2000
Ta osoba razgovara s drugim ljudima.
15:15
That drives tune-in behavior back into mass media,
345
915260
3000
To potiče ponovno uključenje u masovne medije
15:18
and you have these cycles
346
918260
2000
tako da postoje ciklusi
15:20
that drive the overall behavior.
347
920260
2000
koji potiču cjelokupno ponašanje.
15:22
Another example -- very different --
348
922260
2000
Drugi primjer -- vrlo različit --
15:24
another actual person in our database --
349
924260
3000
druga stvarna osoba u našoj bazi --
15:27
and we're finding at least hundreds, if not thousands, of these.
350
927260
3000
a pronalazimo barem stotine, ako ne i tisuće takvih.
15:30
We've given this person a name.
351
930260
2000
Dali smo toj osobi ime.
15:32
This is a pro-amateur, or pro-am media critic
352
932260
3000
On je pro-amater, pro-am, medijski kritičar
15:35
who has this high fan-out rate.
353
935260
3000
koji dopire do velikog dijela javnosti.
15:38
So a lot of people are following this person -- very influential --
354
938260
3000
Tako da mnogi ljudi slijede tu osobu -- vrlo utjecajnu --
15:41
and they have a propensity to talk about what's on TV.
355
941260
2000
i imaju sklonost komentiranju sadržaja na TV-u.
15:43
So this person is a key link
356
943260
3000
Ta je osoba ključna poveznica
15:46
in connecting mass media and social media together.
357
946260
3000
između masovnih medija i društvenih medija.
15:49
One last example from this data:
358
949260
3000
Posljednji primjer iz ovih podataka:
15:52
Sometimes it's actually a piece of content that is special.
359
952260
3000
Ponekad je poseban upravo dio sadržaja.
15:55
So if we go and look at this piece of content,
360
955260
4000
Pa ako promotrimo taj sadržaj,
15:59
President Obama's State of the Union address
361
959260
3000
govor predsjednika Obame o stanju Unije
16:02
from just a few weeks ago,
362
962260
2000
od prije samo nekoliko tjedana,
16:04
and look at what we find in this same data set,
363
964260
3000
pogledajte što pronalazimo u tom istom skupu podataka,
16:07
at the same scale,
364
967260
3000
na istoj razini,
16:10
the engagement properties of this piece of content
365
970260
2000
poticajna svojstva tog dijela sadržaja
16:12
are truly remarkable.
366
972260
2000
zaista su izuzetne.
16:14
A nation exploding in conversation
367
974260
2000
Narod koji odjednom počinje komentirati
16:16
in real time
368
976260
2000
u stvarnom vremenu
16:18
in response to what's on the broadcast.
369
978260
3000
potaknut onime što se emitira.
16:21
And of course, through all of these lines
370
981260
2000
I naravno, kroz sve te linije
16:23
are flowing unstructured language.
371
983260
2000
teče nestrukturiran jezik.
16:25
We can X-ray
372
985260
2000
Možemo napraviti rentgensku snimku
16:27
and get a real-time pulse of a nation,
373
987260
2000
i dobiti stvarni puls naroda,
16:29
real-time sense
374
989260
2000
stvarne podatke
16:31
of the social reactions in the different circuits in the social graph
375
991260
3000
o društvenim reakcijama u različitim krugovima društvenog grafa
16:34
being activated by content.
376
994260
3000
koje aktivira sadržaj.
16:37
So, to summarize, the idea is this:
377
997260
3000
Dakle, da sažmem, ideja je sljedeća:
16:40
As our world becomes increasingly instrumented
378
1000260
3000
Kako nam je svijet sve više automatiziran
16:43
and we have the capabilities
379
1003260
2000
i imamo mogućnosti
16:45
to collect and connect the dots
380
1005260
2000
prikupljati i povezivati točkice
16:47
between what people are saying
381
1007260
2000
između onoga što ljudi govore
16:49
and the context they're saying it in,
382
1009260
2000
i konteksta u kojem to govore,
16:51
what's emerging is an ability
383
1011260
2000
pojavljuje se i mogućnost
16:53
to see new social structures and dynamics
384
1013260
3000
da vidimo nove društvene strukture i dinamiku
16:56
that have previously not been seen.
385
1016260
2000
koje prije nismo mogli vidjeti.
16:58
It's like building a microscope or telescope
386
1018260
2000
To je kao kad sklapate mikroskop ili teleskop
17:00
and revealing new structures
387
1020260
2000
i otkrivate nove strukture
17:02
about our own behavior around communication.
388
1022260
3000
našeg vlastitog ponašanja tijekom komunikacije.
17:05
And I think the implications here are profound,
389
1025260
3000
I mislim da ovo ima duboke implikacije,
17:08
whether it's for science,
390
1028260
2000
bilo za znanost,
17:10
for commerce, for government,
391
1030260
2000
trgovinu, vladu,
17:12
or perhaps most of all,
392
1032260
2000
ili možda, najviše od svega,
17:14
for us as individuals.
393
1034260
3000
za nas kao pojedince.
17:17
And so just to return to my son,
394
1037260
3000
I samo da se vratim na svog sina,
17:20
when I was preparing this talk, he was looking over my shoulder,
395
1040260
3000
dok sam pripremao ovo predavanje, gledao mi je preko ramena
17:23
and I showed him the clips I was going to show to you today,
396
1043260
2000
i pokazao sam mu videozapise koje sam mislio pokazati vama danas
17:25
and I asked him for permission -- granted.
397
1045260
3000
i tražio sam ga dopuštenje -- i dobio ga.
17:28
And then I went on to reflect,
398
1048260
2000
Nakon toga sam razmišljao,
17:30
"Isn't it amazing,
399
1050260
3000
"Nije li to fantastično,
17:33
this entire database, all these recordings,
400
1053260
3000
cijelu ovu bazu, sve snimke,
17:36
I'm going to hand off to you and to your sister" --
401
1056260
2000
predat ću tebi i tvojoj sestri",
17:38
who arrived two years later --
402
1058260
3000
koju smo dobili dvije godine kasnije.
17:41
"and you guys are going to be able to go back and re-experience moments
403
1061260
3000
"A vi ćete se moći vratiti i ponovno proživjeti trenutke
17:44
that you could never, with your biological memory,
404
1064260
3000
kojih se inače, sa svojim biološkim pamćenjem,
17:47
possibly remember the way you can now?"
405
1067260
2000
nikako ne biste mogli sjećati kao što to možete sada."
17:49
And he was quiet for a moment.
406
1069260
2000
On je zašutio na trenutak,
17:51
And I thought, "What am I thinking?
407
1071260
2000
pa sam pomislio, "Što je meni?
17:53
He's five years old. He's not going to understand this."
408
1073260
2000
Ima pet godina. Neće razumjeti ništa od ovoga."
17:55
And just as I was having that thought, he looked up at me and said,
409
1075260
3000
I upravo u trenutku kad sam to pomislio, pogledao me i rekao,
17:58
"So that when I grow up,
410
1078260
2000
"Znači, kad narastem,
18:00
I can show this to my kids?"
411
1080260
2000
mogu ovo pokazati svojoj djeci?"
18:02
And I thought, "Wow, this is powerful stuff."
412
1082260
3000
I pomislio sam "Opa, ovo je moćna stvar."
18:05
So I want to leave you
413
1085260
2000
Za kraj vam želim pokazati
18:07
with one last memorable moment
414
1087260
2000
posljednji trenutak za pamćenje
18:09
from our family.
415
1089260
3000
iz naše obitelji.
18:12
This is the first time our son
416
1092260
2000
Ovo je prvi put da je naš sin
18:14
took more than two steps at once --
417
1094260
2000
napravio više od dva koraka odjednom --
18:16
captured on film.
418
1096260
2000
zabilježeno na filmu.
18:18
And I really want you to focus on something
419
1098260
3000
Želim da obratite pažnju na nešto
18:21
as I take you through.
420
1101260
2000
dok vas vodim kroz snimku.
18:23
It's a cluttered environment; it's natural life.
421
1103260
2000
To je natrpana okolina, svakodnevni život.
18:25
My mother's in the kitchen, cooking,
422
1105260
2000
Moja majka je u kuhinji, kuha,
18:27
and, of all places, in the hallway,
423
1107260
2000
i baš u hodniku
18:29
I realize he's about to do it, about to take more than two steps.
424
1109260
3000
shvaćam da će to učiniti, napraviti više od dva koraka.
18:32
And so you hear me encouraging him,
425
1112260
2000
Čujete me kako ga ohrabrujem,
18:34
realizing what's happening,
426
1114260
2000
shvaćam što se događa,
18:36
and then the magic happens.
427
1116260
2000
i tad nastupa čarolija.
18:38
Listen very carefully.
428
1118260
2000
Slušajte pažljivo.
18:40
About three steps in,
429
1120260
2000
Nakon oko tri koraka,
18:42
he realizes something magic is happening,
430
1122260
2000
on shvaća da se događa nešto čarobno.
18:44
and the most amazing feedback loop of all kicks in,
431
1124260
3000
I uključuje se zadivljujuća petlja povratnih informacija,
18:47
and he takes a breath in,
432
1127260
2000
on udahne,
18:49
and he whispers "wow"
433
1129260
2000
i prošapće "opa"
18:51
and instinctively I echo back the same.
434
1131260
4000
a ja instiktivno odgovorim isto to.
18:56
And so let's fly back in time
435
1136260
3000
Vratimo se nazad u vremenu
18:59
to that memorable moment.
436
1139260
2000
do tog trenutka za pamćenje.
19:05
(Video) DR: Hey.
437
1145260
2000
(Video) DR: Hej.
19:07
Come here.
438
1147260
2000
Dođi ovamo.
19:09
Can you do it?
439
1149260
3000
Možeš li?
19:13
Oh, boy.
440
1153260
2000
Ajme meni.
19:15
Can you do it?
441
1155260
3000
Možeš li?
19:18
Baby: Yeah.
442
1158260
2000
Dijete: Da.
19:20
DR: Ma, he's walking.
443
1160260
3000
DR: Mama, on hoda.
19:24
(Laughter)
444
1164260
2000
(Smijeh)
19:26
(Applause)
445
1166260
2000
(Pljesak)
19:28
DR: Thank you.
446
1168260
2000
DR: Hvala.
19:30
(Applause)
