Cross-Language Retrieval for the CLEF Collections
2019
Preserved Fulltext
For our participation in CLEF, the Berkeley group participated in the monolingual, multilingual and GIRT tasks. To help enrich the CLEF relevance set for future training, we prepared a manual reformulation of the original German queries which achieved excellent performance, more than 110% better than average of median precision. The GIRT task performed English- German Cross-Language IR by comparing commercial machine translation with thesaurus lookup techniques and query expansion techniques.
