Abstract

A data retrieval method and apparatus for designating retrieval of items of data that satisfies a plurality of retrieval conditions, by using retrieval results which have already been retrieved based on one of the retrieval conditions and displayed. An item of data stored in a data storage is retrieved based on a keyword, and an icon of the retrieved data is displayed within an area corresponding to the keyword, on a display window. When a plurality such areas are displayed on the display window, if one area is designated and moved, in accordance with a relative distance between the areas, display positions of icons of data commonly included in the areas are moved closer to each other, while the other icons in the areas are moved away from those in the opposite side. If the areas are overlapped with each other, the icon of data commonly included in these areas is displayed within the overlap.

retrieval means for retrieving data that satisfies a retrieval condition from said data storage means;

display means for displaying an image on a display screen, corresponding to the data retrieved by said retrieval means, within an area provided in correspondence with the retrieval condition;

moving means for moving a first area displayed by said display means on the display screen; and

control means for, if a distance between the first area moved by said moving means and a second area comes to be within a predetermined range, displaying an image of a data that simultaneously satisfies retrieval conditions corresponding to the first and second areas, at positions within each of the first and second areas, closer to each other.

7. The data retrieval apparatus according to claim 6, further comprising input means for inputting the retrieval condition.

8. The data retrieval apparatus according to claim 6, further comprising memory means for storing a retrieval condition and a retrieval result retrieved based on the retrieval conditions by said retrieval means, in correspondence with the areas,

wherein if said display means displays the plurality of areas, said control means refers to retrieval conditions corresponding to the plurality of areas, mutually related to each other, and discriminates data that simultaneously satisfies the retrieval conditions of the plurality of areas.

9. The data retrieval apparatus according to claim 6, wherein if said display means displays a plurality of areas and at least one of the plurality of areas is moved on a display screen, said control means moves images of data in the plurality of areas that respectively satisfy only one of retrieval conditions corresponding to the plurality of areas, away from other areas.

10. The data retrieval apparatus according to claim 6, wherein data are stored, in correspondence with keywords, into said data storage means,

and wherein the retrieval conditions are inputted as keywords.

11. The data retrieval apparatus according to claim 6, wherein an image of data is an icon corresponding to the data.

12. A data retrieval method for retrieving desired data from a plurality of data stored in data storage means, comprising:

a retrieval step of retrieving data that satisfies a retrieval condition from said data storage means;

a display step of displaying an image on a display screen, corresponding to the data retrieved in said retrieval step, within an area provided in correspondence with the retrieval condition; and

a control step of, if a plurality of areas are displayed in correspondence with retrieval conditions respectively on the display screen, displaying an image of data that simultaneously satisfies the retrieval conditions corresponding to the plurality of areas, in an overlap area between the areas.

13. The data retrieval method according to claim 12, further comprising a memory step of storing a retrieval condition and a retrieval result retrieved based on the retrieval conditions by said retrieval means, in correspondence with the areas,

wherein if the plurality of areas are displayed in said display step, retrieval conditions corresponding to the plurality of areas, mutually related to each other, are referred to, and data that simultaneously satisfies the retrieval conditions of the plurality of areas is discriminated, in said control step.

14. The data retrieval method according to claim 12, wherein if a plurality of areas are displayed and at least one of the plurality of areas is moved on a display screen in said display step, images of data in the plurality of areas that respectively satisfy only one of retrieval conditions corresponding to the plurality of areas, are moved away from other areas, in said control step.

15. The data retrieval method according to claim 12, wherein data are stored, in correspondence with keywords, into said data storage means,
