Abstract
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.

Claim 1
Independent Claim
255 words
An information retrieval apparatus for retrieving a map, comprising: an interface for entering a hand-drawn retrieval request, said hand-drawn retrieval request being formed of an object to be retrieved and other elements which are represented by at least a hand-drawn diagram, and representing a spatial positional relationship between the object and the other elements, said hand-drawn diagram comprising characters, a mark and a line, said characters representing at least one of names associated with the other elements and designations representing a direction of the hand-drawn diagram and a unit distance of the hand-drawn diagram, said mark being associated with the object and the other elements, said line being associated with the other elements and a length of the unit distance, said interface comprising entry means for entering said hand-drawn retrieval request, and retrieval request interpreting means for receiving said hand-drawn retrieval request, collating the object and the other elements in the hand-drawn diagram with a words dictionary and interpreting the spatial positional relationship between said object and said other elements based on coordinates of the object and the other elements to form a retrieval condition; data base means for storing specific map data related to said object and said other elements; retrieval executing means for executing an information retrieval based on said retrieval condition formed by said retrieval request interpreting means and the specific map data of said data base means, and outputting a desired retrieval result of the map around the object to be retrieved; and display means for displaying the desired retrieval result.
Claim 2
Dependent Claim
255 words
An information retrieval apparatus for retrieving a map, comprising: an interface for entering a hand-drawn retrieval request, said hand-drawn retrieval request being formed of an object to be retrieved and other elements which are represented by at least a hand-drawn diagram, and representing a spatial positional relationship between the object and the other elements, said hand-drawn diagram comprising characters, a mark and a line, said characters representing at least one of names associated with the other elements and designations representing a direction of the hand-drawn diagram and a unit distance of the hand-drawn diagram, said mark being associated with the object and the other elements, said line being associated with the other elements and a length of the unit distance, said interface comprising entry means for entering said hand-drawn retrieval request, and retrieval request interpreting means for receiving said hand-drawn retrieval request, collating the object and the other elements in the hand-drawn diagram with a words dictionary and interpreting the spatial positional relationship between said object and said other elements based on coordinates of the object and the other elements to form a retrieval condition; data base means for storing specific map data related to said object and said other elements; retrieval executing means for executing an information retrieval based on said retrieval condition formed by said retrieval request interpreting means and the specific map data of said data base means, and outputting a desired retrieval result of the map around the object to be retrieved; and display means for displaying the desired retrieval result.
Claim 3
Dependent Claim
65 words
An information retrieval apparatus according to claim 1, wherein said entry means has symbol menus including plural selectable symbols by which said retrieval request can be formed by menu selection and means for transmitting a code for each selected symbol to said retrieval request interpreting means; and said retrieval request interpreting means includes means for recognizing said retrieval request on the basis of the code.
Claim 4
Dependent Claim
36 words
An information retrieval apparatus according to claim 1, wherein said entry means comprises a tablet device for enabling entry of hand-drawn elements; and said retrieval request interpreting means comprises recognizing means for recognizing said hand-drawn elements.
Claim 5
Dependent Claim
22 words
An information retrieval apparatus according to claim 1, wherein said retrieval request interpreting means forms a retrieval table as the retrieval condition.
Claim 6
Dependent Claim
24 words
An information retrieval apparatus according to claim 1, wherein said retrieval request interpreting means forms retrieval commands in language form as the retrieval condition.
Claim 7
Dependent Claim
192 words
A map retrieval interface for entering a hand-drawn retrieval request of the map, said retrieval request being formed of an object to be retrieved and other elements which are represented by at least a hand-drawn diagram, and representing a spatial positional relationship between the object and the other elements, said hand-drawn diagram comprising characters, a mark and a line, said characters representing at least one of names associated with the other elements and designations representing a direction of the hand-drawn diagram and a unit distance of the hand-drawn diagram, said mark being associated with the object and the other elements, said line being associated with the other elements and a length of the unit distance, the interface comprising: entry means for entering said hand-drawn retrieval request; and retrieval table forming means for receiving said hand-drawn retrieval request, collating the object and the other elements in the hand-drawn diagram with a words dictionary and interpreting the spatial positional relationship between said object and said other elements based on coordinates of the object and the other elements to form a retrieval table representing said spatial positional relationship between said object and said other elements.
