SINAI at Robust WSD Task @ CLEF 2008: When WSD is a Good Idea for Information Retrieval tasks?
نویسندگان
چکیده
This year we have participated in the first edition of Robust WSD task with the aim of investigating the performance of disambiguation tools applied to Information Retrieval (IR). The main interest of our experimentation is the characterization of queries where WSD is a useful tool. That is, which issues must be fulfilled by a query in order to apply an state-of-art WSD tool? After the interpretation of our experiments, we think that only queries with terms very polysemous and very high IDF value are improved by using WSD.

This paper describes the participation of the REINA research group at CLEF 2009 Robust-WSD Task. We have participated in both monolingual and bilingual subtasks. In past editions of the robust task our research group obtained very good results for non-WSD experiments applying local query expansion using co-occurrence based thesauri constructed using windows of terms. We applied it again. For WS...

This paper presents the participation of the semantic N-levels search engine SENSE at the CLEF 2009 Ad Hoc Robust-WSD Task. During the participation at the same task of CLEF 2008, SENSE showed that WSD can be helpful to improve retrieval, even though the overall performance was not exciting mainly due to the adoption of a pure Vector Space Model with no heuristics. In this edition, our aim is t...

The Robust-WSD at CLEF 2009 aims at exploring the contribution of Word Sense Disambiguation to monolingual and multilingual Information Retrieval. The organizers of the task provide documents and topics which have been automatically tagged with Word Senses from WordNet using several state-of-the-art Word Sense Disambiguation systems. The Robust-WSD exercise follows the same design as in 2008. I...
متن کاملApplication of Axiomatic Approaches to Crosslanguage Retrieval
Natural languages contain many ambiguous words. Detecting the correct sense of words within documents and queries could potentially improve the performance of an information retrieval system. This is the major motivation for the Robust WSD tasks of the Ad-Hoc Track of the CLEF 2009 campaign. For these tasks we have build a customizable and flexible retrieval system. The best performing configur...

This paper describes the participation of the IXA NLP group at the CLEF 2008 Robust-WSD Task. This is our first time at CLEF, and we participated at both the monolingual (English) and the bilingual (Spanish to English) subtasks. We tried several query and document expansion and translation strategies, with and without the use of the word sense disambiguation results provided by the organizers. ...
