Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique in which a server appropriately processes a result of information retrieval on a network based on a keyword and presents it to a user computer.

[0002]

BACKGROUND OF THE INVENTION The development of the Internet in recent years has been remarkable. The population of users of the Internet and the amount of information on the Internet are increasing in competition with each other. In such an information-flooding environment, how to organize information is becoming more and more important in order to effectively utilize the obtained information. Therefore, there are many portal sites customized for each individual. These customize the various aspects of information flooding the Internet. However, even if it is a customized section, within the range of predetermined categories of information such as politics, economy, sports, and entertainment, it is possible to change the necessity of the category and the arrangement on the screen according to your preference. Stays in. It is hard to say that it is possible to quickly and properly retrieve information that suits an individual's taste by using such a portal site.

On the other hand, the field of information required by an individual and the method of approaching the desired information are biased depending on the individual's taste. Therefore, there is a tendency to repeatedly search for information using the same keyword every time without knowing it. The inventor paid attention to this.

Therefore, the inventor of the present invention thought that it would be convenient if the history of the keywords used for the search were left on the screen and the result of the search by the keyword could be immediately confirmed.
In addition, I thought it would be convenient if the history of narrowed search by adding keywords was also left on the screen. As described above, an object of the present invention is to provide a technique in which a server appropriately processes a result of information search on a network based on a keyword and presents the result to a user computer.

[0005]

A technique according to the present invention for achieving the above object is to generate a table for each search keyword received from a user computer, register the table in a database, and perform a search based on the keyword. The information on the network is stored in the corresponding keyword table, and the search result stored in each keyword table is output to the corresponding user computer as an object aggregated for each keyword.

BEST MODE FOR CARRYING OUT THE INVENTION <System Configuration Example> FIG. 1 shows a network configuration according to an embodiment of the present invention. As this network, any network including a LAN line can be adopted, but here, the Internet is taken as an example. A server 1 and a large number of user computers 2 are connected to the Internet 3 by telephone lines or leased lines. The user computer 2 is a personal computer and can browse Internet sites through an installed browser.

The user computer 2 does not necessarily have to be connected to the network. The server 1 may be directly connected to the server 1 or the server 1
The hardware may be integrated with the software module and data communication may be performed between the software modules.

The server 1 is a computer operated by an organizer of the search result presentation service according to the present invention. According to the request, the HTTP request / response is exchanged with the user computer 2 that has accessed the server 1, and the result is presented.

The user registers some keywords that he or she can easily use in advance. Then, keyword 1
One card (object) for each word is generated on the display of the user computer 2. On each card, the result (URL, content summary, etc.) of searching the Internet by the keyword is displayed. When a plurality of cards corresponding to a plurality of keywords are used to link the cards on the display, a search is performed by logically combining the keywords according to the form of the link, and the result is displayed.

FIG. 2 exemplifies a display display of the user computer according to this embodiment. In this example, music-related information is organized in one frame 201 by the search result display service according to the present embodiment.
The frame 201 mainly includes a frame 202 for displaying a list of created card names, a frame 203 for a card editing operation button, and an information display frame 204. The card 205 and the link 206 created by the user are displayed in the information display frame 204. Then, the user creates a plurality of such frames 201 so that necessary information can be easily searched and organized.

Each function provided in the server 1 will be described in detail below according to the operation procedure of the user.

<Card Generation> FIG. 3 is a diagram showing a processing flow of the server caused by a user's operation. First, a description will be given using this figure. A user who intends to use the search result presentation service according to the present embodiment first inputs a keyword on the operation screen on the user computer 2 to generate a card in the information display frame 204 on a certain frame 201. A predetermined operation to that effect is performed (step 301 in FIG. 3). Then, the card generation command including these pieces of information is delivered to the server 1. The server 1 that receives this command creates a keyword table as illustrated in FIG. 4 in an appropriate storage unit such as a hard disk device (step 302). The server 1 collects keyword tables corresponding to a large number of keywords input by the user and manages them as a cache database.

The keyword table is mainly composed of six items of "keyword", "synonyms", "narrowing keywords", "search formula", "favorite", and "search result". In addition, the item "Other" is provided,
You may make it memorize | store the content and comment peculiar to the keyword. Here, the keyword input by the user is recorded for the "keyword" item. Other items will be described later.

Further, when a keyword table is created in the cache database by the user's operation of creating a card, the server 1 creates a search expression containing this keyword and delivers it to a search engine inside or outside the server 1. Search Internet sites. When the search result (URL, content summary, etc.) is received, it is stored in the "search result" item of the keyword table (step 303). Further, the retrieval formula at this time is stored in the item of "retrieval formula" of the keyword table described above.

<Cache search> User computer 2
When a card for a certain keyword (this keyword becomes the card name 501) is generated on the display of,
The server 1 reads out the search result recorded in the cache database and returns it to the user computer 2. Upon receiving this, the user computer 2 appropriately displays the search result in the card on the display (step 306). FIG. 5 exemplifies one card displayed on the display of the user computer 2. The search result is displayed in the search result display frame 502 of this card.

Next, a case in which the user establishes a link between two cards for two keywords on the display of the user computer 2 will be described with reference to FIG. As shown in FIG. 6, starting from the card 601 with the keyword “music”, the card 60 with the keyword “KAWATA”
When the operation of linking is determined with 2 as the end point (the return point of the arrow in FIG. 6) (step 304), a search command including these pieces of information is transmitted to the server 1. And on the server 1, "music" is a superordinate concept from the direction of the arrow,
Recognizing that "KAWATA" has been designated as a subordinate concept, a search formula consisting of the logical product of these is generated based on the keyword of each card and the cache database is searched (step 305). That is, "Music and KAWAT
The cache database is searched using "A" as a keyword. Then, the contents of the card 602 of the subordinate concept "KAWATA" are rewritten according to this search formula. That is, the card 602 whose cache database search result by this logical product search expression is "KAWATA"
Is displayed in the search result display frame 502 (step 306). In addition, a new search expression composed of this logical product is stored in the “search expression” item of the keyword table of the “KAWATA” card 602. At this time, the contents displayed on the upper “music” card 601 do not change.

Further, as illustrated in FIG. 7, in addition to the example of FIG. 6, the above-mentioned “KAWATA” card 702 is further added.
If a link is established with the starting point as "CD" card 703 and the ending point (return point as arrow), "CD" card 7
03 is recognized as a subordinate concept of the "KAWATA" card 702, and the result of a search using "music and KAWATA and CD" as a keyword is displayed. In this case, a "music" card 701 and a "KAWATA" card 702
6 is the same as the case of FIG. That is, the result of searching the cache database with "music" as a keyword is displayed on the "music" card 701, and "K" is displayed.
The card 702 of “AWATA” includes “Music and KAWAT”
The result of searching the cache database using "A" as a keyword is displayed. In other words, if there is one card (serial connection) that is designated as a superordinate concept of each card,
The cache database is searched based on a search formula obtained by ANDing the keywords of the upper card and the lower card, and the result is displayed on the card of the lower concept.

Next, a case in which there are a plurality of cards (parallel connection) which are the upper ranks of a certain card will be described with reference to FIG. As illustrated in FIG. 8, a “CD” card 803
"KAWATA" card 80
2 and the "ETL" card 804 are linked to each other, the "KAWATA" card 802 and the "ETL" card 804 are recognized as being synonymous with each other, and the "CD" card 803 is their subordinate concept. Be recognized. In this case, there is no change in the contents displayed on the "KAWATA" card 802 and the "ETL" card 804, but "C
The card 803 of “D” has “(KAWATA or ET
The result of searching the cache database using “L) and CD” as a keyword is displayed. In other words, if there are multiple cards (parallel connection) specified in the superordinate concept of each card, the search formula is obtained by taking the logical sum of the keywords of the multiple superordinate cards and then taking the logical product with the keywords of the subordinate cards. The result of searching the cache database based on is displayed on the card of the subordinate concept.

As described above, when the user confirms the operation of generating a card on the display or establishing a link between the generated cards, the "cache search" is performed to search the cache database at any time. Is done. Of course, you can also delete the link. In this case, the same search as before linking is performed.

<Always collect information> The server 1 appropriately updates the contents of the cache database. That is, check the contents of each keyword table at appropriate intervals,
"Constant information collection" is performed to update the contents as needed.

When collecting information constantly, first, keywords are extracted from each keyword table and synonyms of each keyword are extracted using the dictionary database provided in the server 1. The synonyms extracted at this time are stored in the item “synonyms” of the keyword table. Then, a search formula is generated based on the "keyword" and the "synonyms" to search the Internet site. This search result (URL, content summary, etc.) will be displayed in the "search result" of the keyword table if necessary, such as when there is a change.
Record in the item of. In this way, “always collect information” is performed regularly, and the cache database reflects the latest contents on the Internet.

In the constant information collection, since the search including the synonyms is performed in this way, the cache database stores abundant information (URL etc.) related to the related keywords. Of course, the above-mentioned "cache search" is also performed based on such a cache database that reflects the latest information, so it is possible to efficiently search for the latest information.

If the updated new arrival information is displayed in a conspicuous manner by changing the display color, or if a card with a large number of new arrival information is displayed in front, the user can obtain the information faster. Being able to do it is convenient.

<Favorite Registration> For each card, the user can register frequently used ones from the information (URL, content summary, etc.) displayed in the search result display frame 502. . When the cursor is selected from the displayed information to select it and a predetermined operation to register is confirmed, a registration command including this information (URL or the like) is transmitted to the server 1.
Of course, the URL can be directly specified and registered. Similarly to the above, the operation of inputting the URL at a predetermined location 503 and confirming the registration is confirmed.

Upon receiving the registration command, the server 1 registers in the "favorite" item of each keyword table. Further, it is stored in an appropriate storage unit in association with each keyword and managed as a favorite database.

The information registered in the favorite database here is displayed in thumbnail format 504 on each card on the display of the user computer 2. When the user clicks on the display, the information is displayed in the favorite frame 506.

<Narrowed-down search> When the user adds and inputs a keyword (narrowed-down keyword) to each card on the display of the user computer 2, it is possible to search by further narrowing down the keyword of each card. When the user confirms a predetermined operation of inputting a narrowing-down keyword to a predetermined input location 505 for a certain card, a narrowing-down search command including this information is transmitted to the server 1.

Upon receiving this command, the server 1 records the narrowing-down keyword in the item "narrowing-down keyword" of the keyword table and searches the favorite database. That is, the information (URL, etc.) stored in association with this keyword is retrieved from the favorite database, and the search is performed within that range based on the keyword. In addition, the cache database may be searched based on this keyword and the narrowed keyword. The search result is displayed in the favorite frame 506. This "narrow-down search" function makes it easier to narrow down the information according to the user's taste.

<Frame Generation> In the above, the processing mainly on the frame 201 in which music-related information as shown in FIG. 2 is collected has been described.
It is also possible to create. For example, if a predetermined operation to create the frame 201 is performed using the button in the edit frame 203 of the interface screen illustrated in FIG. 2, a new frame 201 is created. In the example of this figure, for example, a sports-related frame can be newly created to move the "sports" card. It is possible to organize sports-related information by generating a card or linking on the sports-related frame.

<Others> The server 1 manages the number of times the generated card is used (for example, the number of times a link is made or a narrowed search is performed). If a user creates a card, such as information about the season, but the frequency of use (for example, the number of times the card has been used since the card was created) is less than a specified value, the keyword will blink or the text Notify the user by making the color lighter. If the user decides that this card is not needed, it can be easily deleted. With this function, it is possible to organize the display of the user computer 2 so that it is easy to see.

Further, the distance between the cards on the display may be determined according to the similarity of the meaning of each keyword. By doing so, even if the number of cards is large, it becomes easy to visually group the similar concepts and organize the information, and it becomes possible to efficiently find the necessary information. At this time, another frame 201 may be automatically generated and moved with respect to a card having a degree of similarity lower than a predetermined degree of similarity (a long distance).

Alternatively, the card (keyword table) recorded in the server 1 may be disclosed to a third party so that it can be used by other users who can access the server 1. Since it becomes possible to share knowledge and know-how, it is efficient and convenient.

This service is not limited to the Internet search, but it can be used for membership communities, competitive games,
It can be applied to various communication services such as chat. For example, when new members or opponents are added, new posts can be notified, and members with similar tastes have more opportunities to contact each other, so it is easy to communicate with each other. Is beneficial.

According to the present invention, it is possible to organize the information that suits the taste of each individual so that it can be taken out easily. Also,
It becomes easier to watch the latest information.

The embodiment according to the present invention may be as follows in order to achieve the above object. In the method of presenting search results, which of the designation of performing a logical search by linking the keywords and which of the keywords forming a combination in the logical search is a superordinate concept or a subordinate concept of the search or mutually synonymous concepts. And the step of accepting the designation of from the user computer,
Based on the received logical search designation and the conceptual order designation, the logical combination processing of the search results included in the keyword table corresponding to each keyword is executed, and the processing result is stored in the corresponding keyword table according to the conceptual order of the search. And a step of reflecting the stored contents.

At this time, the designation of the link display relation and the arrangement position relation in the user interface between the objects is accepted from the user computer as the logical search designation and the conceptual order designation, so that the objects having the link display designation are made. Is received as the designation of the logical search, and the placement position designation of the object linked in the predetermined direction is recognized as the designation of the conceptual order.

Further, in the search result presentation method, the access frequency from the user computer to the object is managed in the database, and the display mode of the object is changed according to the frequency or the user computer is notified to that effect. I decided to.

Furthermore, in the search result presentation method,
Based on the refined keywords received from the user computer, a keyword table corresponding to the object specified by the user computer or a search result narrowed search for a search result group generated in advance by an extraction instruction from the user computer is performed. It includes the step of performing and the step of displaying the result of the narrowing-down search in the corresponding object or the object for displaying the narrowing-down result.
