BUAP-UPV TPIRS: A System for Document Indexing Reduction at WebCLEF
Abstract:
In this paper we present the results of BUAP/UPV universities in WebCLEF, a particular task of
CLEF 2005. Particularly, we evaluate our information retrieval system at the bilingual ``English to Spanish'' task. Our system uses a
term
reduction process based on the Transition Point technique. Our results show that it is possible to reduce the number of terms to index,
thereby improving the performance of our system. We evaluate different percentages of reduction over a subset of EuroGOV, in order to
determine the best one. We observed that after reducing the 82.55% of the corpus, a Mean Reciprocal Rank of 0.0844 was obtained,
compared with 0.0465 of such evaluation with full documents.
