DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a system configuration of one embodiment of the present invention. An in-house LAN 1 is formed by connecting a number of clients 3 to an in-house server 2. The in-house LAN 1 and the Internet 4 are connected via a gateway 5 which also has a security purpose. A WWW server 6 is also prepared for this in-house LAN 1.

The feature of the present invention resides in that the search server 10 is further connected in such an internet system. The search server 10 is composed of a computer having the functional configuration shown in FIG.

The search server 10 has a large number of keywords as search condition elements and URLs related to those keywords.
The URL database 11 is provided as a contrast table. For example, the contents are shown in FIGS. 5 and 6. FIG. 5 shows a keyword table 21, which is a list of keywords used in the URL table 22 shown in FIG. Therefore, if the keyword is not listed in the keyword table 21, the search is disabled. The URL table 22 shown in FIG. 6 is a comparison table of a large number of URLs and keywords related to each URL. For example, http: //www.toky
The URL o.co.jp/sibaden is also available for mail order at mass retailers in Tokyo and Shibuya, and the items handled are all PC related products. It also indicates that a price list has been posted.

The URL http://www.osaka.co.jp/sakaden is a mass retailer of home electric appliances in Osaka and Nakanoshima, which also sells PC-related products. It also indicates that it is posted.

The search server 10 needs to update the URL table 22 of the URL database 11 periodically, and currently uses various automatic search tools called so-called Internet robots.

The search server 10 also issues a search home page for explaining the search request procedure to the user and issuing a search home page for inputting search conditions.
And a search condition element extracting unit 13 that analyzes the search condition input from the client 3 through the search home page issued by the search home page issuing unit 12 and extracts the search condition element, and the search condition element extracting unit 13 extracts the search condition element. Based on the search condition element, the URL search unit 14 that refers to the keyword list 21 of the URL database 11 and the keyword list of the URL table 22 and picks up the URL in which the matching keyword is listed.
And a plurality of Us picked up by the URL search unit 14
The URL issuance order organizing unit 15 that determines the order in which the URLs are issued based on a preset priority condition for the RL.

The search server 10 further issues a URL with respect to a plurality of URLs ordered by the URL issue order organizing section 15 and sequentially accesses the home page of the corresponding address of WWW.
A URL information collection unit 17 that collects information on each of the homepages accessed by the RL issuing unit 16; a search result editing unit 18 that edits the collected URL information and sends it to the client 3; A transmission / reception processing unit 19 for performing transmission / reception control is provided.

Next, the operation of the Internet search server having the above configuration will be described. As shown in FIG. 3, U of the search server 10 from the client 3 through the in-house LAN 1
When there is an access by designating the RL, the search home page issuing unit 12 of the search server 10 outputs the search home page (Hom).
e Page) is issued and transmitted to the client 3 (step S1).

At the client 3, the user reads the procedure explanation of this search homepage and inputs the search condition according to a predetermined procedure. Now, it is assumed that the search condition input from the client 3 has the content shown in A1 of FIG. In other words, "I want to buy a personal computer of company B in the area A,
I want to know the price of each store. When the search condition element extraction unit 13 of the search server 10 receives the search condition from the client 3 (step S2), the search condition element is extracted (step S3). Here, the elements of "A area", "PC of company B", and "each store price" are extracted (A2).

Subsequently, the URL search unit 14 extracts the keywords included in the search condition elements from the keyword table 21 of the URL database 11, and picks up the URL listing the extracted keywords from the URL table 22 (step S4). . Here is the optimum UR
URL1 to URLX are picked up as L (A3).

Next, some URLs picked up by the URL search unit 14 in the URL issuing order arrangement unit 15
For 1 to URLX, the URL address issuance procedure is determined based on certain priority conditions so that an efficient search can be performed (step S5). To determine the priority order, a method of giving priority to the URL having the number of keywords that best matches the search condition element of the client 3 is suitable.
However, prioritizing regions, prioritizing technical fields,
Set priority conditions in advance, such as giving priority to the country name, or when entering search conditions from the client 3,
It is also possible to employ a method of checking the priority condition and setting the priority order based on the check. A4 shows the issuing procedure thus determined.

After that, the URL issuing unit 16 determines all URLs listed according to the determined issuing procedure.
, The URL address is issued sequentially to access the home page, and the information of the home page is sequentially transmitted to the U.
The data is accumulated in the RL information collecting unit 17 (step S6 and A5 in FIG. 4).

Thus, according to the predetermined address issuing procedure,
When the information collection up to the final URL 3 is completed, the search result editing unit 18 edits the collected information in a predetermined report format and sends it to the client 3 (steps S8 and A6).

Now, the operation of the Internet search server will be described more specifically as follows.

It is assumed that the client 3 writes a search condition on the search homepage issued by the search server in order to know the selling price of each company B company PC in the Tokyo area.

In the search server that receives this, the search condition element detection unit 13 selects "Tokyo area", "personal computer", "B".
When search condition elements such as "company" and "price" are extracted and received by the URL search unit 14, "Tokyo", "Shinjuku", and "Shibuya" are listed as regions included in the "Tokyo region". URLs are candidates, URLs that list "PC" or "Personal computer", "Calculator", "Electronic computer" as keywords related to "Company B personal computer" are candidates, and "Price" is also listed. The extracted URL is extracted as a candidate. Therefore, from the table 22 of FIG.
It is assumed that only URLa and URLb are picked up.

Next, the URL issuance order organizing unit 15 determines which of these URLa and URLb is to be prioritized. In this example, the number of matching keywords is the same, and the keywords are close to each other. Without prioritizing
Information is to be collected in the order of extraction. First, a URL address is issued to collect information of the homepage, and then a URLb address is issued to collect information.

After that, the search result collection unit 18 edits the report format as shown in FIG. 7 and sends it to the client 3. In addition, "I store" is the name of the store that opens the home page of URLa, and "B store"
Is the name of the store at the URLb address.

In this way, according to the Internet search server of this embodiment, the user only needs to access the URL of the Internet search server from the client and input the search condition in the opened search homepage, and the Internet search server side is then in charge. URLs that match the search conditions can be picked up, information can be collected, and the results can be obtained as a report, and the time and effort required for the search can be significantly saved.

Here, the report from the Internet search server may be obtained by a method in which the client side waits while keeping the line connected, but after transmitting the search condition, the line is disconnected once and the form of electronic mail is sent. You can also use the method to have the email sent to the client.
