The TopicsExplorer is a beginner-oriented software allowing interested researchers to experiment with topic modeling on their own computers, with their own text corpora. The entire necessary work flow from plain text to visualized results - some of them even visualized in interactive graphs - is done in a graphical user interface (GUI). The software, thus, allows users without programming skills to load a collection of plain-text or even .xml files and to analyze it by means of the LDA algorithm. As a result, users can scan texts for re-occurring, semantically meaningful groups of words; they can explore how much each of these semantic groups contribute to each text, and which texts probably share the same common themes and topics. For further analysis with other software results can be exported in the universally readable csv format.
