Abstract
An interface, adapted for receiving information composed of symbols, characters, and diagrams representing a spatial positional relationship and used as a retrieval request, comprises an entry device for entering a two-dimensional image, and a retrieval request interpreting device for recognizing elements forming the entered image, such as symbols, characters, and diagrams, and determining a two-dimensional spatial relationship between elements so as to determine retrieval conditions. Information retrieval is executed on the basis of the retrieval conditions determined by the retrieval request interpreting device. Thus, a user is allowed to enter a retrieval request in two-dimensional image form, namely, in an easily intelligible form and in a timesaving manner. This enables makes it possible to retrieve easily sophisticated information as well.
