Natural Language Processing (NLP) group

The Idiap NLP group studies how semantic and discourse processing of texts and dialogues can improve statistical machine translation and information indexing, specifically multimedia retrieval and recommendation.

In statistical machine translation (SMT), we have shown that automatic labeling of discourse-level information (such as the senses of discourse connectives or the tense/aspects of verbs) can be combined with phrase-based SMT systems to improve their accuracy. 

In multimedia retrieval, we have developed a system for just-in-time recommendation of documents in conversations, and showed that topic-aware keyword extraction and semantic search improve its accuracy.  Moreover, we have proposed methods for multimedia recommendation, applied to lectures, TV shows, and their segments, and showed that leveraging user comments can improve collaborative filtering.  Moreover, searching over networked data was improved by using linguistic information and information from the network itself.
