topicmodelling's Introduction

Topic Modeling

The project contains implementations of topic models I have used during my thesis. Those implementations have been used for different papers.

SentenceLDA

In particular, we have proposed the sentenceLDA in the SIGIR 2016 paper : On a topic model for sentences.

CopulaLDA

In particular, we have proposed copulaLDA in the Coling 2016 paper : Modeling topic dependencies in semantically coherent text spans with copulas .

In case you use the model, please cite our paper:

Notes

This is development code and may not be fully functional. That said, the code was tested with Python 2.7 and R 3.1.1 and was functional. Normally, you should be able to reproduce all the experiments reported in the papers.
