Extract as. In that case, the extraction unit 15b uses, among the acquired text information, the text information with a greater weight as the frequency of appearance in the text information stored in the information storage unit 14a of the storage unit 14 as a keyword. It may be extracted.
- the search unit 15e searches for the business document containing the extracted keyword, and presents the business document of the search result to the operator who is the user (step S3).
- the search unit 15c may classify the business document by topic using the appearance probability of the text information appearing in the business document. In that case, the search unit 15c identifies the topic using the text information common to the matter excluding the extracted keywords from the acquired text information, and extracts it from the business document in the specified topic. You may search for business documents that include keywords. As a result, a series of business document presentation processes is completed.
- the storage unit 14 stores the text information displayed on the terminal screen during the processing of the matter in the past.
