This paper presents work on document retrieval for Italian carried out at ITC-irst. Two different approaches to information retrieval were investigated. One based on the Okapi weighting formula and one based on a statistical model. Development experiments were carried out using the Italian sample of the TREC-8 CLIR track. Performance evaluation was done on the Cross Language Evaluation Forum (CLEF) 2000 Italian monolingual track. The two methods achieved mean average precisions of 49.0% and 47.5% respectively, which were the two best scores of their track

Abstract
This paper presents work on document retrieval for Italian carried out at ITC-irst. Two different approaches to information retrieval were investigated. One based on the Okapi weighting formula and one based on a statistical model. Development experiments were carried out using the Italian sample of the TREC-8 CLIR track. Performance evaluation was done on the Cross Language Evaluation Forum (CLEF) 2000 Italian monolingual track. The two methods achieved mean average precisions of 49.0% and 47.5% respectively, which were the two best scores of their trackFile in questo prodotto:
