LDA has recently emerged as the method of choice for working with large collections of text documents. There is a wealth of publications reporting its applications in a variety of text-analysis tasks in general and software engineering in particular. LDA can be used to summarize, cluster, link, and preprocess large collections of data because it produces a weighted list of topics for every document in a collection dependent on the properties of the whole. These lists can then be compared, counted, clustered, paired, or fed into more advanced algorithms. Furthermore, each topic is comprised of a weighted list of words which can be used in summaries.
