Dublin city university at clef 2007: cross-language speech retrieval experiments
Abstract The Dublin City University participation iThe Dublin City University participation in the {CLEF} 2007 {CL-SR} English task concentrated primarily on issues of topic translation. Our retrieval system used the {BM25F} model and pseudo relevance feedback. Topics were translated into English using the Yahoo! {BabelFish} free online service combined with domain-specific translation lexicons gathered automatically from Wikipedia. We explored alternative topic translation methods using these resources. Our results indicate that extending machine translation tools using automatically generated domain-specific translation lexicons can provide improved {CLIR} effectiveness for this task.proved {CLIR} effectiveness for this task.

Conclusion This paper has described results for our pThis paper has described results for our participation in the CLEF 2007 CL-SR track. In 2007 our experiments focussed on the combination of standard machine translation with domain-speci¯c translation resources. Our results indicate that combining domain-speci¯c translation derived from Wikipedia with the output of standard machine translation can produce substantial im- provements in MAP. Further improvements can also be observed when combined with PRF. However, these trends are not observed consistently in all cases, and further investigations will focus on understanding di®erences in behaviour more clearly and re¯ning our procedures for training domain-speci¯c translation resources.ning domain-speci¯c translation resources.
