Abstract

Hummingbird participated in the Finnish, Portuguese, Russian and French monolingual information retrieval tasks of the Cross-Language Evaluation Forum (CLEF) 2004. SearchServer’s experimental lexical stemmers significantly increased mean average precision for each of the 4 languages. For Finnish, mean average precision was significantly higher with SearchServer’s experimental decompounding option enabled. Using the stemming interpretations which led to the highest score in each document instead of using the same interpretations for all documents was of significant benefit for Russian.
