There are a base entry (search start entry) to the directory, a phase (search range), a filter (condition for attribute), and the like.

Next, the operation of the view directory generator 5 having the above configuration will be described.

FIG. 4 is a flowchart showing the operation of the view directory generation unit according to the present invention.

Step 101) First, the directory name provided to the user and the identification name of an entry group satisfying the determination condition of the valid time space area of the user are input.

Step 102) With respect to all the input leaf entry groups, the upper entry is traced.

Step 103) It is determined whether or not the upper entries of all the input leaf entry groups are the same entry. If so, the process proceeds to step 104; otherwise, the process proceeds to step 102.

Step 104) It is determined whether or not the upper entry which is the same entry is the root entry. If so, the process proceeds to step 106, and if not, the process proceeds to step 105.

Embodiments of the present invention will be described below with reference to the drawings.

In the following embodiment, the configuration shown in FIG. 3 will be described as an example.

FIG. 5 shows an example of a facility directory according to an embodiment of the present invention.

In this embodiment, it is assumed that the facility directory shown in FIG. 4 is managed as an example of the directory shown in FIG.

Here, "selection" and "projection" of the directory will be described.

In order to explain these operations, FIG.
(A) shows an example of a selected view directory, and (B) shows an example of a projected view directory. This "selection"
And "projection" operations can be performed simultaneously by combining "selection" and "projection" operations on one directory. For these operations, the view directory definition information 6 manages the names of directories to be operated, operation names of “selection” and “projection” as operation contents, and operation arguments including descriptions about selected entries and projection base entries. . The directory structure is provided as a view directory comprising a classification tree type user interface.

FIG. 6 shows the spatio-temporal information of the user and the attributes of the facility directory according to one embodiment of the present invention. FIG.
(B) shows the spatiotemporal information of the user, and (C) shows the attribute value of the facility directory.

As described above, as the attributes of the entry of the facility directory, the time zone consisting of the start time and the end time of the facility and the facility information mapped on a two-dimensional drawing such as a map indicate the location in the space of the facility. In order to determine the indicated center coordinate value and the rectangle of the space area, the coordinate values of the upper left vertex and the lower right vertex of the rectangle are managed. Similarly, the user's spatio-temporal information also includes, from the current time, the time zone in which the user exists in the space area, the center coordinate value in the space, and the upper left vertex and lower right coordinate of the rectangle indicating the space area Manage values. For the sake of explanation, time and space where providing information is meaningful,
The time space in which the user exists is called the effective space time.

A procedure for generating and providing a view directory by combining the operations of “selection” and “projection” shown in FIG. 5 described above is provided below.

First, the user is presented with the facility directory shown in FIG.

Next, when a search request for space-time information is obtained from the user, first, an entry group included in the effective space-time of the user is obtained from the directory. Therefore, when the relationship between the above-described example of the spatiotemporal information in FIG. 6A and the attribute value of the facility directory in FIG. 6C is associated with the XY coordinate system, the result is as shown in FIG. The entry of the facility directory that intersects with the effective space of the user is the following three entries.

([B 1], [Sum 1], [Yo 1]) Equation (1) At this time, it is determined that the above equation (1) generated by the information search control unit 2 in FIG. 3 is searched. The conditions are as follows.

(Upper left X coordinate of user ≦ lower right X coordinate of facility) AND Equation (2) (lower right X coordinate of user ≧ upper left X coordinate of facility) AND (upper left Y coordinate of user ≧ right of facility) Lower Y coordinate) AND (lower right Y coordinate of user ≤ upper left Y coordinate of facility) AND (start time of facility ≤ start time of user) AND (start time of user ≤ end time of facility) AND [Bi 1] and [Yo 2] are within the effective time space of the user, and [Wa 1] is that the effective range of the facility intersects with the effective range of the user. I have. However, since [sum 2] has a start time of 16:00 and is not included in a valid time zone, it does not satisfy the determination condition.

The view directory generating unit 5 shown in FIG.
Then, the view directory definition information 6 and the view directory user interface 7 of FIG. 8A are generated from a directory having only the classification information of the entry obtained by the determination condition of the above equation (2).

As described above, it is possible to provide information through the dynamic user interface 1 adapted to the effective spatiotemporal region of the user. Similarly, in the case of the example of the spatio-temporal information of FIG. 7B described above, the relationship of FIG.
Output the view directory user interface 7.

If there is an additional view name of an attribute of an entry that satisfies the above-mentioned equation (2), the entry information is presented to the user, and at the same time, the classification tree type of the corresponding view directory is displayed. Add a user interface and provide it to the user interface. In the case of FIG. 9B described above, since the entry provided to the user is ([Y 1], [Y 3], [Travel 1]) Expression (3), the aforementioned FIG. 7 (B) As shown in the figure, "floor information view"
"Tourist route view". Therefore, based on the view directory definition information corresponding thereto, FIG.
The floor information view (A) and the sightseeing route view (B) are added to the user interface 1 as a user interface. As a result, floor information of the inn is provided as a user interface of a classification tree type, and detailed floor guidance can be performed. In addition, the route of the route from the inn [Travel 1] to a Japanese restaurant or a Western restaurant can be determined. And assist the user in navigating the facility.

When there is an operation request for the view directory specified by the operation of tracing the user interface consisting of the view directory, the directory operation conversion unit 4 shown in FIG. Is converted into an operation request for the original directory from which the
, An operation condition for the directory is generated by the information search control unit 2, and the directory operation unit 8 searches the directory 9 and returns the search result to the user.

Although the above embodiment has been described based on the configuration of FIG. 3, each component shown in FIG. 3 is constructed as a program, and a disk device connected to a computer used as an information search device, The present invention can be easily realized by storing the program in a portable storage medium such as a floppy disk, a CD-ROM, or the like, and installing the program when implementing the present invention.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified and applied within the scope of the claims.

[0067]

As described above, according to the present invention, in information retrieval adapted to the user's spatio-temporal domain, the user interface and provided information are switched according to the user's time zone and spatial domain. Therefore, by eliminating the operation objects that do not correspond to the time and space that could not be operated with the fixed user interface, suppressing operations unnecessary for the user, and increasing or decreasing the number of user interfaces, Since the detailed search condition can be easily specified by expanding the range, information with improved convenience can be searched by the user interface corresponding to the user's spatio-temporal region.
