Description of the Related Art In the information-oriented society in recent years, information retrieval technology for retrieving target information from a large amount of various kinds of information is important. Although various information retrieval techniques have been developed, the most commonly used method for retrieving a resource that matches a purpose from a huge resource group is repetition of trial and error. In general, it is rare that information matching the target resource is found immediately after the search is started, and the search action must be repeated to reach the target resource.

For example, the WWW (World
As a method for searching for desired Web contents in the Wide Web space, Google (trademark) (U
RL (Uniform Resource Locator): http: //www.googl
There is a method of using a search engine such as e.com). However, even if a search expression related to the search purpose is given to the search engine, it is not always possible to reach the target Web content by the first search.
In many cases, only the Web content related to the b content is reached.

In this case, a method of re-searching the acquired content, a method of using a hyperlink to another Web content provided by the acquired content, a method of using a link collection, etc. ,
Allows access to desired Web content. The link collection is UR, which is an identifier of Web content.
The L is arranged for each genre to facilitate the search.

In order to facilitate the search for such Web contents, Japanese Patent Laid-Open No. 10-301950 discloses an information circulation support method that enables direct access to effective information in accordance with the suggestions of other users.

A request for acquiring Web content corresponding to a URL is made using the (HyperText Transfer Protocol) protocol. In response to the acquisition request, the WWW server outputs the data of the designated Web content to the Web content acquisition unit 4.

The access log generation unit 5 generates browsing history information (hereinafter also referred to as an access log) regarding the Web content browsed by the user and stores it in the access log storage unit 6. As the access log, the user identifier (US
ER), We which is the link source of the viewed Web content
b Content URL (hereinafter referred to as the link source URL)
(REFER), URL (U) of browsed Web content, and browsing time (DATE) information group (USER, REFER, U, DA
TE) information etc. are considered.

For example, if the user (USER1) has a URL (http:
Browse the web content (//web.page/page.html),
Next, the next web content is browsed by specifying the URL (http://web.page/next_page.html) of the link destination described in this web content. In this case, the access log generation unit 5 uses, for example, (USER1, "", "http://web.page/page.html", "2002-01-" as the access log.
30 19:00:02 ") (USER1," http://web.page/page.html "," http://web.page/next_page.html "," 2002-01-30 19: 0
5:30 ") is output to the access log storage unit 6.
Further, the access log generation unit 5 is also configured to output the search condition information stored in the search engine information storage unit 10 described later to the access log storage unit 6 as an access log. The access log storage unit 6 stores the access log generated by the access log generation unit 5.

Is the link source URL, and when the URL is designated in the URL designating section 202, the link source URL is an empty character string.

The partial route generation unit 7 generates, based on the access log stored in the access log storage unit 6, continuous one-division browsing history information (hereinafter, referred to as a partial route) of the browsed URL and partially It is output to the route storage unit 8.
The partial route storage unit 8 is configured to store the partial routes generated by the partial route generation unit 7.

The partial route selecting unit 9 selects a partial route to be presented to the user from the partial routes accumulated in the partial route accumulating unit 8 and outputs it to the information input / output unit 3 as a display partial route. It has become.

The search engine information storage unit 10 stores a URL representing a search engine (hereinafter, search engine representative URL).
And a URL for executing a search (hereinafter referred to as search execution URL) (hereinafter referred to as search engine information).

The search engine is a special Web content that receives a search condition such as a keyword as a parameter and returns a list of URLs of Web contents that match the search condition.

FIG. 3 shows the search engine information storage unit 1 in FIG.
5 is an explanatory diagram showing an example of search engine information stored in 0. FIG.

In FIG. 3, only two pieces of search engine information are shown in detail. For example, search engine information ("http: //www.search.engine/", "http: //www.search.e" shown in the first line of FIG.
ngine / search.cgi? word = * ") is http: //www.search.engine/searc for search engines where http: //www.search.engine/ is a typical URL.
It indicates that the search is executed by the URL in the format of h.cgi? word = *. Note that "*" indicates a portion in which the search condition is embedded. The access log generation unit 5 uses a character string embedded in “*” as a search condition for a part of the access log.

Next, the operation of the embodiment thus constructed will be described with reference to the flow chart of FIG. 4 and FIGS.
Will be described with reference to the explanatory diagram of FIG.

Now, it is assumed that the user browses the Web contents by the user personal computer connected to the information input / output unit 3. When the user specifies the URL (U) of the Web content via the information input / output unit 3 by the user's personal computer, the Web content acquisition unit 4 specifies the browsing from the specified URL in step 301 of FIG. The WWW server holding the Web content is specified, and the Web content is acquired from the specified WWW server.

At the next step 302, the access log generator 5 receives the user identifier (USER), the link source URL (REFER) of the designated Web content, and the URL (U) of the designated Web content. , Information L = (USER, REFER, U, DATE) of the current time (DATE) pair is generated.

Next, the access log generator 5 adds search conditions to the access log. That is, the access log generation unit 5 specifies the search execution URL for each search engine information stored in the search engine information storage unit 10.
Check if it matches RL (U). For the matched search engine information, the access log generation unit 5 extracts the search condition from the specified URL (U) and adds the extracted search condition and the search engine representative URL to the access log.

For example, the URL (U) designated by the user is the URL shown below, and the search engine information storage unit 1
It is assumed that the search engine information shown in FIG.

Http: //www.search.engine/search.cgi? Wo
rd = computer This URL is search engine information ("http: //www.search.engine/", "http://www.search.
engine / search.cgi? word = * "), the access log generation unit 5 extracts the character string of (computer) which is the search condition. In this case, the access log generation unit 5 is in the access log ("http: //www.search.engine/", "computer")
To add.

Next, in step 303, the partial route generation unit 7 causes the link source URL of the generated access log.
Check if (REFER) is an empty string. If it is not an empty character string, the partial route generation processing shown in steps 304 to 306 is skipped.

In the partial route generation process, first, step 3
In 04, among the access logs stored in the access log storage unit 6, for the access logs having the same user identifier, the access logs whose link source URL is a null character string are acquired in order from the newest time. .

Next, in step 305, the obtained access logs are combined in a tree structure using the link source URL, and in step 306, a URL string for the route from the start point of the tree structure to each end point is generated. Then, the partial route is stored in the partial route storage unit 8 as a partial route.

Next, the generation of the access log and the generation of the partial route will be described in detail using a concrete example.

Now, for example, it is assumed that the Web content shown in FIG. 2 is displayed on a predetermined user personal computer. The URL of this Web content is http://www.web.site/index.html. Here, the user (identifier: USER) uses the URL (http://www.web.page/inde
x.html) should be specified. This URL is given from the information input / output unit 3 to the Web content acquisition unit 4, and
b The content acquisition unit 4 identifies the WWW server identifier (www.
web.page) and find /index.htm for this server
Requests acquisition of Web content corresponding to l.

The access log generator 5 generates the following access log Ln according to the designation of the URL by the user (identifier: USER).

Ln (USER, “”, “http://www.web.site
/index.html ”,“ 2002-01-30 21:10:02 ”) Since the user (identifier: USER) directly specified the URL by the URL specifying unit 202, the access log generated in this case is , As is clear from the above description, the link source URL (REFER) is an empty character string.
The process shifts from step 303 in FIG. 4 to the partial route generation process after step 304.

That is, in the present embodiment, the UR is executed without performing the link processing using the link designation display or the like.
When L is specified, the partial route generation process is performed.

Now, it is assumed that the access log shown in FIG. 5 is recorded in the access log storage unit 6 as the access log of the user (identifier: USER). U1 to U5 of FIG.
Indicates a URL such as http: // ...

For example, in the access log Ln-5, the user (identifier: USER) uses the URL designating unit 202 or the like to set
Direct URL at 19:30:10 on January 30, 002
Indicates that U3 is designated as. Further, in the access log Ln-1 immediately before the access log Ln, the user (identifier: USER) has the original URL "http: //www.www." At 20: 1: 0 on January 30, 2002. site / link.htm
For example, the URL "http://www.web.site/index.htm" is used by using the link designation display in the Web content that is "l".
It is shown that "l" is specified.

In step 304, the partial route generation unit 7
Acquires from the recorded access log Ln-1 to the access log Ln-5 whose link source URL (REFER) is an empty character string. FIG. 6 shows an access log acquired by the partial path generation unit 7.

Next, the partial route generation unit 7 performs step 30.
In 5, the tree structure is created using the link source URL. FIG. 7 shows an example of the tree structure created by the partial path generation unit 7.

First, the partial route generation unit 7 arranges the URL (U3) as the branch 21 which is the starting point, based on the access log Ln-5 having the oldest time. Next, based on the access log Ln-4 whose time is next oldest, the URL (U4) is arranged as the branch 22 next to the branch 21, and the branch 21 and the branch 2 are placed.
Connect to 2. Next, the partial path generation unit 7 determines the URL (U5) based on the access log Ln-3 whose time is next oldest.
Is arranged as a branch 23 next to the branch 22, and the starting point 22 and the branch 23 are connected.

The next access log Ln-2 is the link source UR.
L is U4. That is, from URL (U5) to URL (U
The Web content displayed in 4) is returned. This indicates that the back button 203 has been operated. When the back button 203 is operated,
This is because the cache of the information input / output unit 3 displays the Web content displayed immediately before.

Therefore, in this case, the partial path generation unit 7
Access log Ln-2 with branch 22 as a new starting point.
Based on the URL (http://www.www.site/link.htm
l) is placed as the next branch 24, branch 22 and branch 24
And connect. Finally, based on the access log Ln-1, the URL (http://www.web.site/index.html) is arranged as the next branch 25, and the branch 24 and the branch 25 are connected.

In this way, the tree structure shown in FIG. 7 is obtained.
In the next step 306, the partial path generation unit 7
A sequence of the URL is generated by using a route from the start point of the tree structure to the end point of the branch as continuous browsing history information (partial route) of the URL. FIG. 8 shows a partial route generated by the partial route generation unit 7.

As shown in FIG. 8, the partial route 31 obtained by the branches 21 to 23 has (U3, U4, U5) as the URL string. Also, branches 21, 22, 24, 2
The partial path 32 obtained by 5 is (U3, U4, ht
tp: //www.www.site/link.html, http://www.web.site/i
ndex.html) as the URL string.

When the partial route generation processing by the partial route generation unit 7 is completed, the access log generation unit 5 stores the generated access log Ln in the access log storage unit 6 in step 307.

Thus, by using the user personal computer connected to the information input / output unit 3, the partial route accumulating unit 8 sequentially accumulates partial routes based on the access logs of a plurality of users.

In the next step 308, the partial route selection unit 9 acquires the partial routes P1, P2, ... Including the designated URL (U) in the route from the partial route storage unit 8.
If there are a plurality of applicable partial routes, the partial routes may be further narrowed down according to some standard. For example, when the partial routes are given importance, only the ones having the highest importance may be left, or some of the highest importance may be left.

FIG. 9 shows an example of the partial routes accumulated in the partial route accumulation section 8.

The example of FIG. 9 shows that the partial routes P1, P2, ... Are stored. For example, the partial path P3
Uses (U31, U32, U33, U34) as the URL string.

For example, when the Web content (URL: http://www.web.site/index.html) is displayed as shown in FIG. , URL (http://www.web.page/inde
x.html) should be specified. User (Identifier: USE
It is assumed that the partial route shown in FIG. 9 is accumulated in the partial route accumulating unit 8 when R) specifies the URL.
In this case, the partial route selection unit 9 uses the specified URL.
The partial routes P1 and P2 shown in FIG. 10 are selected as the partial routes including (http://www.web.page/index.html) in the route.

At the next step 309, the partial route selection unit 9 starts U from the start point of each of the acquired partial routes P1 and P2.
Extract the part up to RL (U) and display partial path P1
', P2' is generated.

FIG. 11 shows the display partial paths P1 'and P2' generated by the partial path selecting unit 9. Next, in step 310, the partial path selecting unit 9 gives the generated display partial paths P1 ′ and P2 ′ to the information input / output unit 3,
Present it on the screen of the user's computer.

FIG. 12 is an explanatory diagram showing a display example on the display screen of the user's personal computer. In the display area 201 on the display screen of the user's personal computer, the Web content presentation unit 204
A partial route presenting section 410 is provided below. The partial route presenting section 410 includes display partial routes P1 'and P2'.
A partial route display 411 in which is represented by a character string is displayed.

That is, the upper part of the partial route display 411 is a display based on the display partial route P1 ', and this page has a URL (http://www.link.site/link.html) of We.
From content b, follow the links to see U11, U12,
It is shown that the user has arrived via the Web content of U13. Further, the lower part of the partial route display 411 is a display based on the display partial route P2 ', and in this page, the search formula "web-site" for the search engine of the URL (http://www.search.site/) is displayed. From the Web contents searched by ".
It is shown that the user has reached via the Web contents of U12 and U13.

The display partial route based on the access log of the user of the user's personal computer may not be displayed. Further, the user identifier may be used to specify the user who is considered to be familiar with the search target, and only the display partial route based on the access log of the user may be displayed.

As described above, in the present embodiment, partial routes that are closely related to access to the resources of all users are accumulated based on the sequence of the history of actions performed by each user on the resources. However, by presenting a partial route when one user accesses a resource thereafter, the user can learn how to search. In addition, the partial route also includes the search condition specified for the search engine, and it is possible to learn about the optimum keyword for the search. This embodiment can be applied to various information searches using Web contents. For example, if you are looking for a store where you can eat delicious local food in a tourist area, you can purchase a guidebook about the tourist area and go to the restaurant area listed in the guidebook first and actually see it. You can search for the restaurant you want, or other related local restaurants or sightseeing in the neighborhood, by noticing the process of searching other people while going to the area to explore the store. It will be relatively easy to search local restaurants and the like.

The method of generating a partial route from the access log shown in this embodiment is an example, and the partial route may be generated from the access log by another method. Further, for example, the partial routes may be given importance, and when the same partial route is already accumulated in the partial route accumulating section, the importance of the accumulated partial routes may be increased.

In addition, "the more times it is viewed, the more W
If the evaluation criterion that "eb content has a high degree of importance" is adopted, the number of times of browsing of Web content may be recorded as an access log. In this case, the access log generation unit 5 generates an access log and checks from the access log storage unit 6 whether the user has browsed the designated Web content before.
The number of times of browsing may be calculated, and 1 may be added to the calculated number of times of browsing and then added to the generated access log.

In the first embodiment, an example has been described in which the invention is applied to the one that supports the search when browsing the Web content. Furthermore, the present invention is applicable to various cases of acquiring information.

FIG. 13 is a block diagram showing a second embodiment of the present invention related to such another application example.

In this embodiment, continuous action history information (hereinafter referred to as a partial route) of continuous action history information among action history information based on a large number of actual action patterns (following route) of a human being is displayed in a predetermined presentation unit. By presenting it, it is possible to easily grasp the optimal behavior necessary for oneself.

The present embodiment is an example applied to a fishing spot information providing system that provides a fishing spot information providing service.
This fishing ground information providing system is premised on using a network composed of a plurality of information communication terminals capable of transmitting information on the current position (position information) to a base station.

Since each type of fish has unique habits, the place to live and the behavior pattern also differ depending on the type. It also moves sensitively to changes in the weather. A skilled angler will be familiar with the behavior of such fish. Therefore, a service that provides the activity history of a skilled angler is useful.

Therefore, in the present embodiment, the base station regularly receives the position information from the information communication terminals carried by each user, while the user can catch the target fish. When trying to move from one place to the next fishing ground, the candidate for the moving destination is calculated from the information on the current position of the user and the action history of other anglers and presented to the user. .

Specifically, when the user requests the base station to provide the information of the next fishing spot at the place where the target fish is caught, the base station selects the action history of other anglers.
Regarding the behavior history of an angler that includes a position near the current position in the history sequence, a partial route from the start point of the history sequence to a position near the current position is presented to the user as information on the next fishing spot.

Here, in order to search and present information using the place where the target fish was caught as a key, a skilled fisherman should pass mainly through the place where the target fish can be caught, Therefore, there is a high possibility that other place information having history that includes the place where the target fish was caught is suitable for catching the same fish.

In FIG. 13, an information acquisition support device 51 provided in a base station (not shown) includes a plurality of mobile communication terminals H.
1, H2, ... (Hereinafter, also representatively referred to as a mobile communication terminal H) has a communication section 52 capable of communicating. As the mobile communication terminals H1, H2, ..., PHS, mobile phones, etc. can be considered. The mobile communication terminals H1, H2, ... Send the coordinate information (for example, latitude and longitude values), weather information (for example, temperature), and time to the communication section 52 as current position information on a regular basis. There is. In addition, the mobile communication terminals H1 and H2
The user who possesses the ... Can send the following fishing spot information acquisition request irregularly.
The following fishing point information is transmitted from the communication section 52 to the mobile communication terminals H1, H2, ... In response to a request from the user.

The communication section 52 includes mobile communication terminals H1, H2,
The information from ... Is output to the action log generation unit 53. The action log generation unit 53 includes the identifier ID, the coordinate information (X, Y), the weather information (T) and the time of the position of the mobile communication terminals H1, H2, ... That are transmitted from the mobile communication terminals H1, H2 ,. An action log that is a set of D (ID, (X, Y), T, D) is generated and output to the action log storage unit 54. The action log storage unit 54 stores the action log.

The partial route generation unit 55 has the action log storage unit 5
The partial route which is a partial partial action sequence (action history information) is generated from the action log accumulated in No. 4 and is output to the partial route accumulating unit 56. The partial route storage unit 56 stores the sequentially input partial routes.

Various methods can be considered as the method of generating the partial path. For example, a method of mechanically dividing the action sequence for each certain time period P can be considered. A method of dividing the action sequence when the position information deviates significantly from the predetermined range is also conceivable. Furthermore, a method of dividing the action sequence when the amount of change in position information per unit time exceeds a predetermined threshold value is also conceivable.

The partial route selecting section 57 is connected to the partial route accumulating section 5.
A partial route to be presented to the user is selected from the partial routes accumulated in 6, and is output to the mobile communication terminals H1, H2, ... As a partial route for display via the communication unit 52.

Next, the operation of the embodiment thus configured will be described.

First, the process of accumulating partial paths will be described with reference to the flowchart of FIG.

Each mobile communication terminal H1, H2, ... Shows the identifier (ID) of each mobile communication terminal H1, H2, ..., Current position information (X, Y), Weather information (T) and Time (D). It is periodically transmitted to the communication unit 52. The communication unit 52 receives the information received from the mobile communication terminals H1, H2, ...
Output to 3. As a result, the action log generation unit 53 starts the action log generation process in step 601 of FIG. That is, the action log generation unit 53 receives the received ID,
A set of (X, Y), (T), and (D) L_NOW = (ID, (X,
Y), T, D) are generated.

In the next step 602, the action log generation unit 53 displays the action log L_PREV having the latest ID as the identifier of the mobile communication terminal H among the action logs stored in the action log storage unit 54. Take it out. As a result, for the same user, the current action log L_NOW and the immediately previous action log L_PREV are read by the action log generation unit 53.

Next, the action log generator 53 executes step 6
In 03, each element value included in the current action log L_NOW based on the recently received information is compared with each element value included in the immediately preceding action log L_PREV accumulated for this user. As a method of comparison, for example, the value obtained by squaring the difference between the element values and summing them is an arbitrary constant
If it is smaller than H, there is a method to consider that these two action logs are similar. The comparison method is not particularly limited. For example, after weighting each type of element value,
The difference between element values may be squared.

When the action log generator 53 determines that the two action logs are similar as a result of the comparison, it does not record the action log L_NOW in the action log accumulator 54, but instead the action log L_PREV. The coordinate value of the current action log L_NOW
Replace with the average value of the coordinate value of L and the coordinate value of the previous L_PREV. Also, the evaluation value of the action log L_PREV is increased by 1 (step 604). The evaluation value is a value held together with the action log, and the initial value is 0.

Results of comparison Two action logs L_NOW and L_PRE
If it is determined that Vs are not similar, the current L_NOW
Is stored in the action log storage unit 54 (step 605).
That is, when the user's position, weather, time, etc. changes relatively, it is assumed that the user has taken a new action.
The history of the action log is newly updated.

When the action log L_NOW is stored in the action log storage unit 54, the partial route generation unit 55 continues the partial route generation processing. First, the partial path generation unit 55
In step 606, among the action logs accumulated in the action log accumulating unit 54, the action log L1 whose ID is the identifier of the mobile communication terminal H and whose time is included in the time section [NOW-Q, NOW]. Take LN. Here, NOW indicates the current time, and Q is an arbitrary constant value indicating the time.

Next, the partial route accumulating unit 56 executes the step 6
In 07, the obtained action log series L1 to LN are stored in the partial route storage unit 56 as the partial route P. That is, in this example, the collection of each action log generated in Q time is set as the partial path P. As described above, various methods can be considered as a method of generating the partial route P from the accumulated action log. For example, the history of the action log (partial route P) may be generated by detecting a significant distance from the fishing log from the action log, and the moving speed is extremely high, for example, when moving by a car. The partial route P may be generated by detecting that it is early from the action log.

15 and 16 are explanatory views specifically showing the generation of the partial route P. As shown in FIG. FIG. 15 shows the action history of an angler in a lake (portion with a satin pattern). Black squares 701 to 709 are, for example, the action history obtained from the action log of the angler A having the mobile communication terminal H1 plotted on a map, and the white squares 710 to 710.
In FIG. 14, the action history obtained from the action log of the angler B having the mobile communication terminal H2 is plotted on the map.

The action history is the mobile communication terminal H1,
Based on the information transmitted to the communication unit 52 by H2, ..., The black square marks 701 to 703, 70 surrounded by circles
6, 707 are based on the action logs that are considered to be similar by the comparison process of step 603.

FIG. 16 shows the action history finally obtained from the action log accumulated in the action log accumulating section 54, plotted on the map with the same marks as in FIG. The numerical value in the parentheses in FIG. 16 indicates the evaluation value of the action log.

Next, the processing for presenting the fishing ground information will be described with reference to the flowchart in FIG.

When the user uses the mobile communication terminal H to request the provision of the next fishing spot information, the mobile communication terminal H receives the communication section 52.
On the other hand, a combination (ID, ID) of the mobile communication terminal H, current position information (X, Y), weather information (T), and time D (ID,
(X, Y), T, D) together with a request to provide the next fishing spot information. Upon receiving the information from the mobile terminal H, the communication unit 52 starts the processing for presenting the next fishing spot information.

That is, the partial route selection unit 57 causes the step 9
In 01, the partial route accumulating unit 56 includes the partial routes P1, P2, ... Which include position information having coordinate information within a certain distance R from the coordinate information (X, Y) of the current position information.
To get from. Here, R is an arbitrary constant. Also,
Coordinate information (X, Y) included in the partial paths P1, P2, ...
Positional information having coordinate information within a certain distance R from is defined as L1 ', L2', ....

Next, the partial route selection unit 57 causes the step 9
In 02, the parts from the starting point to L1 ', L2', ... are extracted from each of the acquired partial paths P1, P2, ... to generate display partial paths P1 ', P2' ,.

If there are a plurality of relevant partial routes, the partial route selecting unit 57 may narrow down the display partial routes to be presented according to some standard. For example, for each of the acquired partial routes P1, P2, ..., the sum of the evaluation values of the action logs included in the partial routes is obtained, and only the largest one is left, or some of the largest ones are left. May be.

Next, in step 903, the communication unit 5
2 is the generated display partial paths P1 ', P2', ...
Is transmitted to the mobile communication terminal H. In this case, the communication unit 5
2 also sends the evaluation value of the action log included in each display partial path to the mobile communication terminal H together.

When the mobile communication terminal H receives the display partial paths P1 ', P2', ... From the communication section 52, the display partial paths P1 ', P2' ,. Present. In this case, for example, an action log having a high evaluation value in the display partial route may be emphasized and presented.
The high evaluation value of a certain action log indicates that the angler stayed in the vicinity of the place indicated by the action log for a long time. That is, the position where the angler has been fishing is emphasized and presented, and it is easy for the user to recognize an important part in the partial route for display.

FIG. 18 is an explanatory diagram showing a specific example of the display of the display partial path displayed to the user by the mobile communication terminal H. A white square mark 1001 indicates the current position of the user who has made the next ball for presenting fishing spot information, and a black square mark 1002
Reference numeral 1007 represents a candidate for the next fishing spot. The size of the black square mark corresponds to the size of the evaluation value of the action log corresponding to the position.

The display of FIG. 18 makes it possible to grasp the actions of other users who have reached their current position before. The user indicated by the white square is 10
At the point of 07,1004, it is shown that it has stopped relatively long.

As described above, in the present embodiment, the action log of each user is accumulated based on the information from a plurality of users, and a partial route which is a series of action history of one segment is obtained from the action log, It is presented at the request of the user. With this, from the behavior pattern of a skilled angler,
You can learn about valid fishing points and apply them to subsequent fishing.
