Comparative study of monolingual and multilingual search models for use with asian languages

Jacques Savoy
2005 ACM Transactions on Asian Language Information Processing  
Based on the NTCIR-4 test-collection, our first objective is to present an overview of the retrieval effectiveness of nine vector-space and two probabilistic models that perform monolingual searches in  ...  analyze the relative merits of the various automated and freely available toolsto translate the English-language topics into Chinese, Japanese, or Korean, and then submit the resultant query in order to retrieve  ...  Thus, when compared with corresponding monolingual searches in which we translated user information from English into Chinese, Japanese, or Korean languages, overall retrieval effectiveness decreases more  ...

Report on CLEF-2003 Monolingual Tracks: Fusion of Probabilistic Models for Effective Monolingual Retrieval [chapter]

Jacques Savoy
2004 Lecture Notes in Computer Science  
Our second goal was to suggest a combined search approach based on a data fusion strategy that would work with various European languages.  ...  For our third participation in the CLEF evaluation campaign, our first objective was to propose more effective and general stopword lists for the Swedish, Finnish and Russian languages along with an improved  ...  As a second probabilistic approach, we implemented the Prosit (PRObabilistic Sift of Information Terms) approach [Amati 2002a [Amati , 2002b which is based on the following indexing formula: w ij = Inf  ...

Combining Multiple Strategies for Effective Monolingual and Cross-Language Retrieval

Jacques Savoy
2004 Information retrieval (Boston)  
This paper describes and evaluates different retrieval strategies that are useful for search operations on document collections written in various European languages, namely French, Italian, Spanish and  ...  In order to cross language barriers, we propose a combined query translation approach that has resulted in interesting retrieval effectiveness.  ...  However, Amati et al. (2003) indicated that the PROSIT probabilistic model performed better than the Okapi approach, at least for the Italian collection.  ...
