MAIMAI: A Question Answering System at NTCIR3 QAC-1
نویسندگان
چکیده
This paper describes an question answering system based on syntactic information. Our system extracts answer candidates by ranking of score which shows similarity of syntactic structure. Syntactic structure is estimated based on answer type, density of weighty words, distance between words and depth of parse tree. To analyze syntactic structure, morphological analysis, named entity extraction and parser are utilized. The system was used for runs of Task1 and Task2 on NTCIR3 QAC-1 and Experiments were conducted with the formal run test set. Results showed 0.157 mean reciprocal rank(MRR) for Task1 and 0.78 mean F value(MF) for Task2.
