Text Mining, or how to Read Lots of Texts with no Time

The hands-on seminar (part II) will introduce the participants to the topic modeling methodology. To this end, we will use the programming language R, together with a few R libraries for text mining and topic modeling. A typical scenario that involves converting texts to their lemmatized version, chunking, removing stopwords, and training a topic model, will be discussed. A set of ready-to-use scripts in R will be provided, therefore no programming skills are required/expected.
