ABOUT THE WORKSHOP
Topic modelling is a popular tool for modelling document collections and has seen applications in a variety of domains, from medical science to digital humanities. Topic models provide an effective means of extracting topics from large document collections and have the advantage that they require no supervision or document labels. While topic models can be trained automatically, judicious processing of their output is often required in applications where human users interact directly with the topics generated by a model. For example, the raw output from topic models can be difficult to interpret and consequently labels (manually assigned or automatically generated) are often added to increase readability; visualisation of the relationship between documents and topics is not intuitively obvious and its design requires thoughtful consideration. In addition, topics can contain unrelated words which may make the navigation of the document collection difficult; a typical approach to tackle this is to filter out low quality topics by computing topic coherence. This workshop aims to bring together a wide range of tools and methodologies used in post-processing the output of topic models, with the goal of improving their usability and interpretation within user applications.
