TopicExplorer is a web-based topic model browser that helps non-technical users to analyze data. Data is typically a collection of text pieces like blog posts, book chapters, Wikipedia pages, articles in journals and newspapers. Without the need of any further input, a topic model learns a number of word lists that often can be interpreted as topics. TopicExplorer helps users to explore the semantics of the learned topics with several visual and interactive features. The ecosystem around the TopicExplorer browser include web applications to filter text corpora, tune the vocabulary used in the analysis and create new topic models.
TopicExplorer-docker is a docker-compose project that allows simplified installation and configurations of all components of TopicExplorer on Linux, Windows and Mac.
