Concept-Based Searching and Merging for Multilingual Information Retrieval: First Experiments at CLEon a deep linguistic analysis of documents and queries that aims at categorizing them in terms of concepts and implements an original search algorithm inherited from the SPIRIT (EMIR) system that takes into account this categorization.

CLEF 2003 Experiments at UB: Automatically Generated Phrases and Relevance Feedback for Improving CLge multilingual retrieval tasks. We used a modified version of the SMART system, a heuristic method based on bigrams to generate phrases that works across multiple languages, and pseudo relevance feedback. Query translation was performed using publicly available machine translation software. Our res

Merging Results by Predicted Retrieval Effectivenessieval effectiveness was used to adjust the similarity scores of documents in the result lists. We introduced three factors affecting the retrieval effectiveness, i.e., the degree of translation ambiguity, the number of unknown words and the number of relevant documents in a collection for a given qu
