Ork de Rooij, Tom Kenter, Maarten de Rijke, Eickhoff, C., de Vries, A.P. · 2013
xTAS is an extendable multi-user text analysis service for large scale multi-lingual document analysis developed at the University of Amsterdam. It can process large amounts of documents in a timely manner through a web interface that can be used by multiple users at once. In this demonstration paper we present recent additions which include semanticization, on the fly TF-IDF model generation and on the fly co-occurrence metrics. Furthermore, we demonstrate ThemeStreams, a novel topic monitoring tool built on top of xTAS.
