Abstract: An email preparation assisting device automatically produces human-relations information about human relations with a recipient to whom an email is to be sent. In order to realize this, term extraction member extracts terms from emails stored in a sent/received email storing section. Term usage frequency calculation member calculates the usage frequency of each extracted term, and adds it to the usage frequency of the term stored in a term usage frequency storing section. Human-relations information producing member weights human-relations basic information associated in advance with each term in a term association list for each communication partner with the usage frequency of the term for the communication partner stored in the term usage frequency storing section to produce human-relations information based on the result of the weighting operation. The produced human-relations information is stored in a human-relations information storing section separately for each communication partner.

Abstract: Questions and answers associated with each other are stored in a document storage section. A clustering section classifies the answers in the document storage section 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 question similar to the input question, and presents answers associated with the retrieved question together for each cluster to the user or an expert. In addition, the database retrieval/updating section automatically updates the document storage section based on an answer selected as most appropriate by the user or the expert if selected, or based on an answer newly input by the expert if no appropriate answer is available. The natural language answer input by the expert is presented to the user as it is.
