Follower Networks and “List Intelligence” List Contexts for @JiscCetis

I’ve been tinkering with some of my “List Intelligence” code again, and thought it worth capturing some examples of the sort of network exploration recipes I’m messing around with at the moment.

Let’s take @jiscCetis as an example; this account follows no-one, is followed by a few, hasnlt much of a tweet history and is listed by a handful of others.

Here’s the follower network, based on how the followers of @jiscetis follow each other:

Friend connections between @Jisccetis followers

There are three (maybe four) clusters there, plus all the folk who don’t follow any of the @jisccetis’ followers…: do these follower clusters make any sort of sense I wonder? (How would we label them…?)

The next thing I thought to do was look at the people who were on the same lists as @jisccetis, and get an overview of the territory that @jisccetis inhabits by virtue of shared list membership.

Here’s a quick view over the folk on lists that @jisccetis is a member of. The nodes are users named on the lists that @jisccetis is named on, the edges are undirected and join indivduals who are on the same list.

Distribution of users named on lists that jisccetis is a member of

Plotting “co-membership” edges is hugely expensive in terms of upping the edge count that has to be rendered, but we can use a directed bipartite graph to render the same information (and arguably even more information); here, there are two sorts of nodes: lists, and the memvers of lists. Edges go from members to listnames (I should swap this direction really to make more sense of authority/hub metrics…?)

jisccetis co-list membership

Another thing I thought I’d explore is the structure of the co-list membership community. That is, for all the people on the lists that @jisccetis is a member of, how do those users follow each other?

How folk on same lists as @jisccetis follow each other

It may be interesting to explore in a formal way the extent to which the community groups that appear to arise from the friending relationships are reflected (or not) by the make up of the lists?

It would probably also be worth trying to label the follower group – are there “meaningful” (to @jisccetis? to the @jisccetis community?) clusters in there? How would you label the different colour groupings? (Let me know in the comments…;-)

Using Twitter Lists to Define Custom Search Engines

A long time ago, I used to play with search engines all the time, particularly in the context of bounded search, (that is, search over a particular set of web pages of web domains, e.g. Search Hubs and Custom Search at ILI2007). Although I’m not at IWMW this year, I can’t not have an IWMW related tinker, so here’s a quick play around IWMW related twittering folk…

To start with, let’s have a look at the IWMW Twitter account:

IWMW lists

We see there are several twitter lists associated with the account, including one for participants…

Looking around the IWMW10 website, I also spy a community area, with a Google Custom search engine that searches over institutional web management blogs that @briankelly, I presume, knows about:

Institutional Web Managemet blogs search engine

It seems a bit of a pain to manage though… “Please contact Brian Kelly if you would like your blog to be included in this list of blogs which are indexed”

Ever one to take the lazy approach, I wondered whether we could create a useful search engine around the URLs disclosed on the public Twitter profile page of folk listed on the various IWMW Twitter lists. The answer is “not necessarily”, because the URLs folk have posted on their Twitter profiles seem to point all over the place, but it’s easy enough to demonstrate the raw principle.

So here’s the recipe:

– find a Twitter list with interesting folk on it;
– use the Twitter API to grab the list of members on a list;
– the results include profile information of everyone on the list – including the URL they specified as a home page in their profile;
– grab the URLs and generate an annotations file that can be used to import the URLs into a Google Custom Search Engine;
– note that the annotations file should include a label identifier that specifies which CSE should draw on the annotations:

Google CSE config

Once the file is uploaded, you should have a custom search engine built around the URLs folk followed in the twitter list have revealed in their twitter profiles (here’s my IWMW Participants CSE (list date: 12:00 12/7/10)

Note that to create sensibly searchable URLs, I used the heuristics:

– if page URL is or, search on*
– by default, if page is, just search on that page.

I used Python (badly!;-) and the tweepy library to generate my test CSE annotations feed:

import tweepy

#these are the keys you would normally use with oAuth

#these are the special keys for single user apps from
#as described in
#select your app, then My Access Token from the sidebar

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(key, secret)
api = tweepy.API(auth)

#this identifier is the identifier of the Google CSE you want to populate


auth = tweepy.BasicAuthHandler(accountName, password)
api = tweepy.API(auth)




#use the Cursor object so we can iterate through the whole list
for un in tweepy.Cursor(api.list_members,owner=listowner,slug=tag).items():
    if  type(un) is tweepy.models.User:
      if l:
        if not l.endswith('/'):
          if l[-1]=="/":
        f.write("\t\t<Annotation about=\""+l+"\" score=\"1\">\n")
        f.write("\t\t\t<Label name=\""+cse+"\"/>\n")



(Here’s the code as a gist, with tweaks so it runs with oAUth.)

Running this code generates a file (listhomepages.xm) that contains Google custom search annotations for a particular Google CSE, based around the URLs declared in the public twitter profiles of people listed in a particular list. This file can then be uploaded to the Google CSE environment and used to help configure a bounded search engine.

So what does this mean? It means that if you have a identified a set of people sharing a particular set of interests using a Twitter list, it’s easy enough to generate a custom search engine around the webpages or domains they have declared in their Twitter profile.
