Feifei: Neil, what are you doing? That's
0
7220
3100
00:10
the biggest spreadsheet I've ever seen!

00:14
Neil: Hi, Feifei. Yes, just you wait.
2
14300
2140
00:16
I'm developing a product
3
16458
1793
00:18
that will revolutionise
4
18251
1719
00:19
English teaching!
5
19970
1200
00:21
Feifei: Great. So why are you looking at
6
21170
2290
00:23
screens of numbers?
7
23460
1460
00:24
Neil: Not numbers, data. Big data!
8
24920
3600
00:28
This is what I need. And that is
9
28520
2320
00:30
the expression we're
10
30840
1030
00:31
talking about in The English We Speak.
11
31870
2020
00:33
Feifei: How do you plan to use this data?
12
33890
2239
00:36
Neil: I haven't figured it out yet.
13
36129
2143
00:38
But that's not important.
14
38272
1560
00:39
Everyone's talking about big data.
15
39840
2420
00:42
Feifei: It is a hot topic. But big data is
16
42260
3208
00:45
all about analysis. You need to know what
17
45468
3132
00:48
to do with all that data.
18
48600
1750
00:50
Neil: Right.
19
50350
1000
00:51
Feifei: What you are looking at is
20
51350
1930
00:53
a list of... football scores...
21
53280
3180
00:56
from every country...
22
56460
1660
00:58
in 1987?!
23
58120
1240
00:59
Neil: Ah, yes. Not useful?
24
59360
2159
01:01
Feifei: Sadly not! Let's listen to this
25
61520
3360
01:04
explanation of what big data actually is.
26
64880
3620
01:11
We are surrounded by data. Every time
27
71020
3860
01:14
we use social media, buy
28
74888
2117
01:17
something online, or even search
29
77005
2195
01:19
for information, we are creating data.
30
79200
4740
01:23
Because there's so much of it,
31
83940
1680
01:25
and because it comes
32
85620
1880
01:27
in many forms, we call it big data.
33
87500
3920
01:31
Companies collect and analyse big data
34
91420
3800
01:35
to discover hidden trends and patterns.
35
95220
4380
01:39
For example, online retailers use big data
36
99600
4480
01:44
to learn what kinds of things customers like,
37
104080
3740
01:47
so they can suggest new products to buy.
38
107820
4680
01:54
Feifei: You're listening to The English We
39
114320
1300
01:55
Speak from BBC Learning English.
40
115620
2420
01:58
Our expression in this
41
118048
1062
01:59
programme is 'big data'. So, Neil,
42
119110
3092
02:02
how's your research going now?
43
122202
2728
02:04
Neil: Not well. It's hard to know
44
124930
2035
02:06
where to start.
45
126965
925
02:07
Feifei: Well, you'll probably need
46
127890
1836
02:09
information on things like spending
47
129726
1924
02:11
patterns on language
48
131650
1100
02:12
learning apps, key times users
49
132750
2279
02:15
log in and how long sessions last,
50
135029
2634
02:17
how demand varies
51
137663
1317
02:18
by language level, data on first languages,
52
138980
2554
02:21
data on which kind of content is most...
53
141540
2080
02:23
Neil: OK. Stop, stop, stop. I'm trying
54
143620
2340
02:25
to write all this down. Feifei?
55
145980
2400
02:28
Feifei: Yes?
56
148380
1080
02:29
Neil: Can I hire you as a big data analyst?
57
149460
2200
02:31
Feifei: Sorry, Neil, you're too late. I'm
58
151670
2410
02:34
launching a product of my own.
59
154083
1805
02:35
It helps predict
60
155888
962
02:36
football scores. In fact, I need a bit
61
156850
3090
02:39
more data from...1987!
62
159960
2560
02:42
Neil: Well, I might just be able
63
162520
1500
02:44
to help you out there!
64
164040
1570
02:45
Feifei: Yes, I think you were actually
65
165610
1750
02:47
looking at my screen earlier.
66
167360
1800
02:49
Neil: Sorry! You know, I think I'll leave
67
169160
2460
02:51
this big data stuff to the experts.
68
171620
2940
02:54
Feifei: Bye.
69
174560

02:55
Neil: Bye.
