00:00:05,590 --> 00:00:09,880
Today I'm going to be showing you a 
quick, easy way for you to be able to 

2
00:00:09,880 --> 00:00:15,770
download and extract Facebook data. 
So the first thing you're going to do is 

3
00:00:15,770 --> 00:00:20,046
go to facebook.com, and you're going to 
open your page. 

4
00:00:20,046 --> 00:00:24,342
So for example, this is my page. 
And then your going to go up here and 

5
00:00:24,342 --> 00:00:29,541
type in the word Netvizz. 
This is going to pull up an app that will 

6
00:00:29,541 --> 00:00:34,610
allow you to be able to use and extract 
Facebook data. 

7
00:00:34,610 --> 00:00:38,630
So we're going to select this app, and 
because I've used it before then it's 

8
00:00:38,630 --> 00:00:44,600
going to take me right in, but it will be 
asking you to be able to go ahead. 

9
00:00:44,600 --> 00:00:47,848
So what you'll see is that we've got 
Netvizz pulled up here, and this is 

10
00:00:47,848 --> 00:00:51,320
going to allow us to extract data from 
different sections of Facebook for our 

11
00:00:51,320 --> 00:00:54,820
research purposes. 
Alright. 

12
00:00:54,820 --> 00:00:57,902
So what I'm going to do is, I'm going to 
be, not choosing my own personal network, 

13
00:00:57,902 --> 00:01:00,680
but I'm going to be choosing a group 
network. 

14
00:01:00,680 --> 00:01:02,870
And we'll be selecting a group in just a 
moment. 

15
00:01:02,870 --> 00:01:06,620
You could also choose pages. 
For example, if there's pages that you 

16
00:01:06,620 --> 00:01:10,790
have participated in, you can look at 
previous posts. 

17
00:01:10,790 --> 00:01:15,137
And so what I'm going to do is we're, 
should note that retrieve comments for 

18
00:01:15,137 --> 00:01:20,210
pages are limited to 800 per post because 
of the API. 

19
00:01:20,210 --> 00:01:23,000
And so what we're going to do is go ahead 
and choose a group. 

20
00:01:23,000 --> 00:01:26,132
So, for example, in this case I'm 
going to choose the Clintonville Crime 

21
00:01:26,132 --> 00:01:30,910
and Block Watch Monitor, and I want to 
extract the friendship connections. 

22
00:01:32,620 --> 00:01:35,860
So we're going to go ahead and press that 
button, and it's going to go through a 

23
00:01:35,860 --> 00:01:40,980
process of Netvizz operating and pulling 
that data for us. 

24
00:01:40,980 --> 00:01:43,700
This will take a couple of minutes, so be 
patient. 

25
00:01:43,700 --> 00:01:46,830
You'll see that this is in fact 
operating. 

26
00:01:46,830 --> 00:01:49,550
Okay, what you see is that it is 
retrieving users. 

27
00:01:49,550 --> 00:01:52,890
So we've got the number of users that are 
being retrieved. 

28
00:01:56,230 --> 00:01:59,686
As you'll see, it takes a while, but 
eventually all of the connections will be 

29
00:01:59,686 --> 00:02:05,780
pulled up. 
In this case there are 1,857 connections. 

30
00:02:05,780 --> 00:02:09,812
And so what will happen is that it has 
created these notes and edges, and we're 

31
00:02:09,812 --> 00:02:15,773
going to get a file, it's a GDF file. 
So we're going to right-click, and save 

32
00:02:15,773 --> 00:02:21,417
this, and what will we what we will be 
doing is saving this with a name that we 

33
00:02:21,417 --> 00:02:31,170
can understand. 
For example, this one is the Clintonville 

34
00:02:31,170 --> 00:02:36,216
Crime Group. 
And you can save it to a location on your 

35
00:02:36,216 --> 00:02:42,030
computer, and that's all you have to do. 
What will happen is that we're going to 

36
00:02:42,030 --> 00:02:45,580
show you next week how to use this file 
that you have downloaded. 

37
00:02:45,580 --> 00:02:49,610
If you want to look at multiple 
neighborhoods or multiple organizations, 

38
00:02:49,610 --> 00:02:53,705
you can go ahead and repeat this process, 
and then we'll be able to conduct an 

39
00:02:53,705 --> 00:02:59,056
analysis in next week's class. 
And next week I will be able to analyze 

40
00:02:59,056 --> 00:03:02,116
the connections, the friendship 
connections, between people that are 

41
00:03:02,116 --> 00:03:07,160
participating in this Clintonville Crime 
and Block Watch Monitor group. 

42
00:03:07,160 --> 00:03:10,260
So these are all people who live in my 
community, and we'll see how we're 

43
00:03:10,260 --> 00:03:11,832
interrelated. 

44
00:03:11,832 --> 00:03:23,997
