  • Patent number: 5649193
    Abstract: A document detection system using a detection result presentation that can facilitate a user's quick comprehension of the relevancy of each detected document. In this system, a user's input for commanding a document detection is analyzed to extract keywords and viewpoints relevant to each keyword contained in the user's input, and a detection command is constructed from the keywords and the viewpoints extracted from the user's input. Then, the detection operation is executed to detect those documents among a plurality of stored documents which match with the constructed detection command as detected documents for a detection result. The detection result can be presented in the multi-dimensional display formed by setting the viewpoints to axes with the detection command as an origin and using distances of the detected documents with respect to the origin for each viewpoint as coordinates of the detected documents with respect to each axis representing each viewpoint.
