摘要：Questions and answers associated with each other are stored in a documentstorage section. A clustering section classifies the answers in the document storagesection into clusters based on feature vectors of the answers. When a natural language

question is input by the user, a database retrieval/updating section retrieves a questionsimilar to the input question, and presents answers associated with the retrievedquestion together for each cluster to the user or an expert. In addition, the databaseretrieval/updating section automatically updates the document storage section based onan answer selected as most appropriate by the user or the expert if selected, or basedon an answer newly input by the expert if no appropriate answer is available. The naturallanguage answer input by the expert is presented to the user as it is.
