Cross-Language Information Retrieval: the way ahead

Fredric C. Gey, Noriko Kando, Carol Peters
2005 Information Processing & Management  
We present our view of some major directions for CLIR research in the future.  ...  In addition, we find that most CLIR evaluation has focussed narrowly on the news genre to the exclusion of other important genres such as scientific and technical literature.  ...  The first NTCIR was held in 1997 and the fourth series is now under way.  ...
