Vipra
The Vipra application is a topic modeling based search system with a frontend web application, a backend REST service and a maintenance tool for data import and modeling. It attempts to leverage automatically discovered topic informations in document collections to ease collection browsing and organization. The search system relies on ElasticSearch and Apache Lucene.
This application was created by Eike Cochu for his master's degree thesis in computer science, 2015-2016 at the Freie Universität in Berlin, Germany.
