### Pre-requisites ###

The code has been developed using Anaconda 2.3 and the LDA module version 1.0.2

Install Anaconda 2.3 from https://repo.continuum.io/archive/ and then 
> pip install lda==1.0.2

In the learn/lda directory
--------------------------
To train the TF-LDA module:
> python lda_learn_tf_news.py

To train the TW-LDA module:
> python lda_learn_tw_news.py

In the learn/lsi directory
--------------------------
To train the TF-LSI module:
> python lsi_learn_tfs_newsgroups.py

To train the TW-LSI module:
> python lsi_learn_tws_newsgroups.py

In the test/lda directory
--------------------------
To predict using the TF-LDA module:
> python tf_ds_news_group.py

To predict using the TW-LDA module:
> python tw_ds_testsallgow_newsgroup.py

In the test/lsi directory
--------------------------
To predict using the TF-LSI module:
> python tf_ds_tests_news.py

To predict using the TW-LSI module - degree centrality:
> python tw_ds_testsalldegree_gow_news.py

To predict using the TW-LSI module - in-degree centrality:
> python tw_ds_testsallindegree_gow_news.py

To predict using the TW-LSI module - out-degree centrality:
> python tw_ds_testsalloutdegree_gow_news.py

To predict using the TW-LSI module - weighted-degree centrality:
> python tw_ds_testsallweighteddegree_gow_news.py
