DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a browsing search apparatus in which information data to be searched is arranged in an information search space, and a user browses information while moving in the information search space.

[0002]

2. Description of the Related Art In recent years, information to be searched is arranged in a two-dimensional or three-dimensional information search space, and information (hereinafter referred to as "walk-through") that a user seeks while moving in the information search space (hereinafter referred to as "walk-through"). Hereinafter, the information arranged in the information search space is referred to as “information data”.) When the information data to be browsed is found, the more detailed contents of the information data are browsed by designating the information data. An information search device that can perform the search has been put to practical use. Such an information search method in which the information data is arranged in the information search space and the user searches for the desired information data while walking through is hereinafter referred to as browsing search.

[0003] On the other hand, an information search method in which, for example, a keyword is input and information matching the keyword is searched, as in a normal online information search, is hereinafter referred to as a hunting search.

Normally, a hunting search is first performed by inputting a keyword or the like, and then the searched information is arranged in an information search space and a browsing search is performed, whereby the desired information data is browsed in more detail. A conventional browsing search device is disclosed in JP-A-9-259130.

[0005]

However, in the above-mentioned conventional browsing search device, once the information obtained as a result of the hunting search is once placed in the information search space, the information in the information search space is further reduced from that state. There was a problem that data could not be added or narrowed down. Specifically, in order to add or narrow down the information data in the information search space, it is necessary to restart the hunting search from the beginning, so that the amount of user work such as keyword input and the processing of the browsing search device are performed. This has led to a decrease in efficiency.

Reconstructing means for reconstructing the information search space based on the data.

Here, the determining means searches for information corresponding to the feature quantity obtained by the feature quantity specifying means from all information to be searched, and has not been arranged in the information search space until then. Information can be newly arranged in the information search space.

[0015] Further, the deciding means arranges only information data corresponding to the characteristic amount obtained by the characteristic amount specifying means in the information search space from the information data arranged in the information search space up to that time. It is also possible to do so.

Further, the recording medium of the present invention is a recording medium on which a program for realizing a browsing search device in which information data is arranged in an information search space and an operator browses the information data while moving in the information search space is recorded.
