Evaluating a probabilistic model for cross-lingual information retrieval

Jinxi Xu, Ralph Weischedel, Chanh Nguyen
2001 Proceedings of the 24th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '01  
It also produces slightly better results than using a machine translation system for CLIR, but the improvement over the MT system is not significant.  ...  For Spanish the system achieves 85% of monolingual performance using only a "pseudo-parallel" Spanish-English corpus.  ...  TEST COLLECTIONS Three test corpora were used in our experiments: TREC5 Chinese track (TREC5C), TREC9 cross-lingual track (TREC9X) and TREC5 Spanish track (TREC5S).  ...

Empirical studies on the impact of lexical resources on CLIR performance

Jinxi Xu, Ralph Weischedel
2005 Information Processing & Management  
In this paper, we compile and review several experiments measuring cross-lingual information retrieval (CLIR) performance as a function of the following resources: bilingual term lists, parallel corpora  ...  corpus for Arabic-English, stemming hurt performance in our empirical studies with Arabic, a highly inflected language.  ...  TREC5&6C collections (Mandarin).  ...

Phrasal translation and query expansion techniques for cross-language information retrieval

Lisa Ballesteros, W. Bruce Croft
1997 SIGIR Forum  
First, we study the importance of phrasaI translation for this approach.  ...  Failure to translate multi-term phrases has km shown to be one of the factors responsible for the errors associated with dictionary methods.  ...  Acknowledgments We'd like to thank Mark Davis end others at the CRL lab at New Mexico State University for the use of tools such as Norm, which facilitated access to the Collins b-al MRDs.  ...

The Use of Ontology in Retrieval: A Study on Textual, Multilingual and Multimedia Retrieval

Muhammad Nabeel Asim, Muhammad Wasim, Muhammad Usman Ghani Khan, Nasir Mahmood, Waqar Mahmood
2019 IEEE Access  
This paper reviews modern ontology-based information retrieval methods for textual, multimedia, and cross-lingual data types.  ...  Ontological information retrieval systems retrieve data based on the similarity of semantics between the user query and the indexed data.  ...  by producing the F-score of 11.90% compared to 9.2% on TREC5 data.  ...
