A Unified Approach to Japanese and English Question Answering.
Edward W. D. Whittaker, Julien Hamonic, Sadaoki Furui · 2005
We present our unified approach to question answering in different languages and describe our experiments on the Japanese language NTCIR-3 Question Answering Challenge (QAC-1) tasks 1 and 2. The model we use for Japanese language question answering (QA) is identical to the one we have applied successfully on the English language TREC QA tasks, based on a novel statistical, non-linguistic and datadriven approach to question answering. Using this method on the formal run of QAC-1 we obtain an MRR of 0.340 on task 1 and an average F-score of 0.159. The top1 accuracy of 26.5 % compares very well with results obtained using an identical approach on the TREC evaluations.
