Event description

Description

Topic Modelling is one of the most powerful and widely used computational methods for analyzing the content of text. Topic models can be used to summarize, explore and annotate large corpora of data, from manifestos to patient reports and Facebook posts. They are particularly powerful when the size and scope of a dataset means that traditional qualitative methods of content analysis cannot be easily used. However, topic models can be difficult to fit and interpret, and they are sometimes used without a full understanding of how they work.

In this hands-on two-class workshop we show you how to implement an LDA topic model in R, covering how to clean your data, fit the model, and interpret the output (all materials are provided for you to use after the workshop). We also discuss the advantages and limitations of topic modelling, provide a brief overview of their theoretical background and point to some exciting recent extensions of the classic LDA topic model. By the end of the workshop you should be ready to start using topic models in your own work.

Spaces are limited and available on a first come first served basis. Attendance is free. We strongly recommend you attend both classes as they cover different material. If you have any queries, please email bertievidgen@gmail.com
