Latent Dirichlet Allocation (LDA) topic modeling is a method for analyzing the distribution of semantic word clusters, so-called "topics" in collection of texts. In history it can be used for exploring the content of a corpus of digital sources.Topic modeling is based on a statistical analysis of co-occurrence for words. It does not use dictionaries or external training data. Topic modeling is a flexible method for computational text analysis.The Topics Explorer of DARIAH-DE is designed as a very user friendly tool. It allows researchers to experiment with topic modeling on their own computers.The work flow from plain text to visualized results is done in a graphical user interface. The software allows users to load a collection of plain-text or xml-files and to analyze it by means of the LDA algorithm.It runs on Windows, MacOS and Linux without installation.
