Dublin City University at CLEF 2007: Cross Language Speech Retrieval (CL-SR) Experiments
نویسندگان
چکیده
The Dublin City University participated in the CLEF 2007 CL-SR English task. For CLEF 2007 we concentrated primarily on the issues of topic translation, combining this with search field combination and pseudo relevance feedback methods used for our CLEF 2006 submissions. Topics were translated into English using the Yahoo! BabelFish free online translation service combined with domain-specific translation lexicons gathered automatically from Wikipedia. We explored alternative translations methods with document retrieval based the combination of the multiple document fields using the BM25F field combination model. Our results indicate that extending machine translation tools using automatically generated domain-specific translation dictionaries can provide improved CLIR effectiveness.

The University of Chicago participated in the CLEF 2007 CL-SR track, performing monolingual retrieval for both English and Czech and cross-language French-English retrieval. English experiments considered the impact of automatically generated keywords on retrieval. Czech experiments explored the effect of different stemming approaches on retrieval for this morphologically rich language. The bes...

This paper presents the participation of the University of Ottawa group in the Cross-Language Speech Retrieval (CL-SR) task at CLEF 2007. We present the results of the submitted runs for the English collection. We have used two Information Retrieval systems in our experiments: SMART and Terrier, with two query expansion techniques: one based on a thesaurus and the second one based on blind rele...
