Twitter chat on #AskLetters1916

About every month the Letters of 1916 project organises a Twitter chat. Different topics related to the letters project have been discussed in the past – Women in the Great War, Crowdsourcing, etc. Tonight the discussion was about Text Analysis and Topic Modelling of the 1916 letters.

Here is a link to the Twitter page: Link


Gephi for the 1916 Letters

Gephi is a suit for interactive visualisation of network data. It is very often used for topic modelling in the Digital Humanities. As an introduction I suggest just play around with it, a how-do reading would be Gephi for the historically inclined. The best is however to get a few data sets and just try to use Gephi. For examples see the following blogs:

Essentially a challenge is to transform the output you get from Mallet or Gensim into a useful input for Gephi (edges and nodes files). On his blog Elijah goes into detail explaining how he visualized the Mallet output.

I wrote a function in my export/outputter module that converts Mallet output to Gephi edges data and saves it to a file. To view the module feel free to have a look at my project on GitHub.
