Ontology-based Tamil–English cross-lingual information retrieval system

D Thenmozhi, Chandrabose Aravindan
2018 Sadhana (Bangalore)  
Cross-lingual information retrieval (CLIR) systems facilitate users to query for information in one language and retrieve relevant documents in another language.  ...  In general, CLIR systems translate query in source language to target language and retrieve documents in target language based on the keywords present in the translated query.  ...  We also thank the anonymous reviewers for their constructive comments, which helped us to improve the manuscript.  ...
