From CLIR to CLIE: some lessons in NTCIR evaluation

Cross-language information retrieval (CLIR) facilitates the use of one language to access documents in other languages. Crosslanguage information extraction (CLIE) extracts relevant information in finer granularity from multilingual documents for some specific applications like summarization, question answering, opinion extraction, etc. This paper reviews CLIR, CLQA, and opinion analysis tasks in NTCIR evaluation. The design methodologies and some key technologies are reported. Categories and Subject Descriptors H.3.3 [Information Storage and Retrieval]: Information Search Retrieval–Search process. General Terms Algorithms, Measurement, Performance. Keywords CLIE, CLIR, Evaluation, Opinion Analysis, Question Answering.
