Clairvoyance Corporation Experiments in the TREC 2003 High Accuracy Retrieval from Douments (HARD) Track

The Clairvoyance team participated in the HARD Track, submitting fifteen runs. Our experiments focused primarily on exploiting user feedback through clarification forms for query expansion. We made limited use of the genre and related text metadata. Within the clarification form feedback framework, we explored the cluster hypothesis in the context of relevance feedback. The cluster hypothesis s...

Cross-Language Experiments with IR-n System

This paper describes the third participation of IR-n system at CLEF-2003. Two previous participation are focused on Spanish monolingual task. This year, we participated in three different tasks: multilingual task (four languages), bilingual task (Italian-Spanish) and monolingual task (Spanish, German, French, Italian). This paper describes the experiments carried out as training process in orde...

Resolving Translation Ambiguity using Monolingual Corpora. A Report on Clairvoyance CLEF-2002 Experiments

Choosing the correct target words is a difficult problem for machine translation. In cross-language information retrieval, this problem of choice is mitigated since more than one translation alternative can be retained in the target query. Between choosing just one word as a translation and keeping all the possible translations for each source word, one can apply a range of filtering techniques...

MIRACLE Approaches to Multilingual Information Retrieval: A Baseline for Future Research

This paper describes the first set of experiments defined by the MIRACLE (Multilingual Information RetrievAl for the CLEf campaign) research group for some of the cross language tasks defined by CLEF. These experiments combine different basic techniques, linguistic-oriented and statistic-oriented, to be applied to the indexing and retrieval processes.
