twitter_networkx_concept_map

Take streaming tweets, extract hashtags & usernames, create graph, export graphml for Gephi visualisation

Write-ups:

Asknowledgements:

The code here is based on Maksim Tsvetovat's tutorial at PyCon 2013 https://us.pycon.org/2013/schedule/presentation/29/

Goal:

Turn a set of streamed Twitter firehose JSON tweets into a Twitter concept net showing commonly discussed pairs of hashtags and users.

Here we see a plot from my blog post http://ianozsvald.com/2013/03/18/semantic-map-of-pycon2013-twitter-topics/ demonstrating the hashtags and usernames that were grouped together at PyCon 2013. White is #hashtags, purple is @usernames:

Example usernames hashtags for pycon2013

Using the above data inside Gephi I extract a set of communities:

Example usernames hashtags for pycon2013

Requirements:

You need a set of streamed tweets, I can't provide my set as the Twitter Usage Agreement forbids distribution of raw tweets. I've included a summary file which can be used in networkx (and gephi) which does not include tweet text or creation dates (as per the Twitter requirement).

You can get your own set of streamed tweets using:

 $ curl -s -uUSERNAME:PASSWORD -X POST -d 'track=pycon' https://stream.twitter.com/1.1/statuses/filter.json -o tweets_pycon.json

You can leave this running via a script (e.g. get_tweets.sh) using:

nohup curl -s -uUSERNAME:PASSWORD -X POST -d 'track=pycon' https://stream.twitter.com/1.1/statuses/filter.json -o tweets_pycon.json > nohuppycon.log &

You also need the following:

* twitter-text-python
* networkx

The easy way to get these is to install:

$ pip install -r requirements.txt
$ pip install -r requirements_2.txt  # installs matplotlib after numpy from first requirements file

Note the above use of 2 requirements files is due to a matplotlib setup issue: https://github.com/matplotlib/matplotlib/wiki/MEP11

Usage:

To parse the raw Twitter JSON into a cleaned local version use:

$ extractor_content.py --json-raw eg_tweets_pycon.json -o clean_pycon.json

Note that you have to provide eg_tweets_pycon.json, I do provide a clean_pyson.json from my data.

To build a graph network from the cleaned data use:

$ extractor_content.py --json-cleaned clean_pycon.json  --remove-nodes #pycon #python #pycon2013 @pycon 

To build the above and draw the graph use --draw-networkx:

$ extractor_content.py --json-cleaned clean_pycon.json  --remove-nodes #pycon #python #pycon2013 @pycon --draw-networkx

To save a graphml output (for importing into Gephi) use:

$ extractor_content.py --json-cleaned clean_pycon.json  --remove-nodes #pycon #python #pycon2013 @pycon --write-graphml pyconout.graphml

Other arguments:

--remove_usernames_below n  # strip users with less than n occurrences
--remove_hashtags_below n  # strip hashtags with less than n occurrences

Output just the text from tweets in the named period:

$ python extract_tweet_updates_to_file.py --json-raw <something>.json --text-file text.txt --ff 2013-04-11T22:00:10.044491+00:00 --ft 2013-04-11T23:00:00+00:00

To output just a filtered set of data (keeping anything except RTs in the date range):

$ extract_tweet_updates_to_file.py --json-raw <something>.json --output reduced_raw.json --ff 2013-04-11T22:00:10.044491+00:00 --ft 2013-04-11T23:00:00+00:00

Todo:

Remove various types of quotes to normalise phrases:

  • how we all lost\u2019 (double quotes)
  • how we all lost' (single quote)
  • consider adding root URLs (e.g. bbc.co.uk) or URL titles

Perhaps following URL link shortners and then take the domain name as a new link in the graph (e.g. bbc.co.uk, techcrunch.com).
