The motivation for most of the papers is that the use of topic modelling enables the possibility to do an analysis on a large amount of documents, as they would otherwise have not been able to due to the Topic Modeling Parameters. Because the topic model is the cornerstone of the whole project, the decisions I made in building it had sizable impacts on the final product.
