Overview of the CLEF-2007 Cross-Language Speech Retrieval Track

The CLEF-2007 Cross-Language Speech Retrieval (CL-SR) track included two tasks: to identify topically coherent segments of English interviews in a known-boundary condition, and to identify time stamps marking the beginning of topically relevant passages in Czech interviews in an unknown-boundary condition. Six teams participated in the English evaluation, performing both monolingual and cross-language searches of ASR transcripts, automatically generated metadata, and manually generated metadata. Four teams participated in the Czech evaluation, performing monolingual searches of automatic speech recognition transcripts.
