CLEF 2004 cross-language spoken document retrieval track

Abstract

This paper summarizes the Cross-Language Spoken Document Retrieval (CL-SDR) track held at CLEF 2004. The CL-SDR task at CLEF 2004 was again based on the TREC-8 and TREC-9 SDR tasks. This year the CL-SDR task was extended to explore the unknown story boundaries condition introduced at TREC. The paper reports results from the participants showing that as expected cross-language results are reduced relative to a monolingual baseline, although the amount to which they are degraded varies for different topic languages. © Springer-Verlag Berlin Heidelberg 2005.
