The Information and Language Processing Systems group is part of the Intelligent Systems Lab Amsterdam at the Informatics Institute of the University of Amsterdam. Our research is aimed at intelligent information access, especially in the face of massive amounts of information. We work on content analysis (information retrieval, machine translation, language technology), the analysis of structural information (social networks, semi-structured data, linked data) and the analysis of user behavior (log analysis, click models, user studies).

We combine fundamental, experimental and applied research, and we do so using a broad range of textual data, data from the web, from enterprises, feed-based, edited, user generated, or obtained from (automatic) transcriptions of audio or video. We are involved with a large number of projects with other groups, both within and outside academia. Our research is funded by NWO, KNAW, the EU and through a range of public-private partnerships.
