Question Answering (QA) is a technique that retrieves the correct answers from a large corpus to questions asked in natural language. QA, which has recently been extensively developed mainly in the United States, is an open-domain system and does not require a knowledge database. In this paper, we introduce a Japanese QA system, SAIQA, which has been developed at NTT Communication Science Laboratories. We outline some of the key technologies used in SAIQA, and describe world trends and future research topics related to QA technology.
