DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for automatically collecting public information, and more particularly to a method and apparatus for automatically collecting public information which can reduce the cost, time, and labor required to obtain necessary information. The present invention relates to such a computer program or a computer-readable recording medium on which the computer program is recorded.

[0002]

2. Description of the Related Art With the spread of EC (Electric Commerce) between companies, the procurement and bidding of goods and services using a public communication line network such as the Internet have become widespread as business.

[0003] When a person who intends to bid is to collect procurement information, "Yahoo" (Yahoo Japan Corporation), "Lycos"
(Carnegie Mellon University) and other search engines to perform keyword searches.
The person in charge selects a site that has useful procurement information.

Then, the address of the site is stored, and the site is searched periodically as needed to collect necessary information.

[0005] Or, for such a site,
"Namiri bastard" (BUG), Web
The address can be registered in an automatic patrol tool such as Auto “(Yanasoft) to collect homepage information. In the homepage search system of Japanese Patent Application Laid-Open No. H10-154152, only the information of a further narrowed page can be obtained. By automatically patrol, homepage information can be efficiently collected, and the entire homepage obtained as a result can be referred to by the person in charge.

[0006]

However, such a task involves manually totaling information that differs for each page, checking differences from past information with a human system, and obtaining new procurement information. is there. After that, it refers to the stock information on the main system, which is another system, and finds out the bidding products. Therefore, in such work, after the work automated by the homepage search system,
There is a problem that it takes a great deal of load on the person in charge to find out a bidding product.

[0007] Furthermore, there are cases where a plurality of persons in charge collect the same procurement information in a redundant manner, or information is not shared among persons in charge, resulting in inefficient work. In addition, since manual work is the main task, it is difficult to complete information collection frequently, and if information collection work is not performed, new procurement information will be overlooked and business opportunities will be lost. You will miss it.

[0008] The type and amount of stock of one's own stock which is to bid for a bid changes daily. In addition, procurement information that is open to the public on the Internet and is profitable for the business on the premise of such stocks is constantly changing. Therefore, it is not possible to judge a bid unless proper processing suitable for inventory and procurement is performed based on the latest information. In addition, there is a problem that business opportunities are lost due to such reasons.

Although the procurement information has been described as an example, the externally provided information of the present invention is not limited to such procurement information. For example, the same can be applied to purchase information and the like.

And a procurement difference information generation unit that generates difference information of the unified procurement information by comparing By the the manner provided, is obtained by solving the above problems.

Further, the public information automatic collection device compares the stock information of the procured item to be provided to the public procurer with the difference information, so that the bidding for the relevant public procurer can be determined or performed. The provision of the bid information collection processing unit that automatically generates necessary information can further reduce costs, time, and labor.

Further, the computer according to the third invention of the present application is:
The problem has been solved by providing a computer program for implementing the above-described automatic public information collecting method or the above-described automatic public information collecting apparatus.

Further, a computer-readable recording medium according to a fourth aspect of the present invention solves the above-mentioned problem by providing a computer-readable recording medium storing the computer program.

Hereinafter, the operation of the present invention will be briefly described.

According to the present invention, among sites provided by a number of information publishers who publish externally provided information via a communication network, a site from which an information searcher should collect desired externally provided information is determined in advance. Register. At the same time, the format conversion rules of the externally provided information acquired from the externally provided information collection destination and the item item codes included in the externally provided information at the externally provided information collection destination are registered in advance.

The item item code distinguishes item items from each other, and the present invention does not specifically limit the item items. For example, if the externally provided information is procurement information or purchase information, the item item is, for example, an item code as in the embodiment described later.

The registration of the externally provided information collection destination site described above
For example, it includes the name of the site on the Internet for which the externally provided information is to be confirmed, and includes a URL (uniform r).
It contains the address of the site and other information in the form of an esource locator. Further, the item item code registration is for unifying the names and item item codes of the item items that are different for each externally provided information provider, and includes a name-to-name, a name-to-item-item code, an item-item code-to-name, It does not specifically limit the form of the conversion definition, such as item item code versus item item code.

The externally provided information acquired via the communication network based on the registration of the externally provided information collection destination site is format-converted based on the format conversion rule. After the conversion, the item item code is converted based on the item item code registration. This allows
It is possible to generate unified externally provided information. The unified externally provided information, regardless of the site of the externally provided information provider,
The item items can be recognized by the unified format and the unified item item names.

Further, by comparing the unified externally provided information obtained in the past with the unified externally provided information obtained this time, difference information of the unified externally provided information is generated. The difference information on item items has a unified format and names item items regardless of the site of the externally provided information providing source. Further, since the difference information can focus on new externally provided information or changed externally provided information, such information is useful, for example, for a person in charge of making a bid or purchasing.

As described above, according to the present invention, it is possible to reduce the cost, time, and labor for acquiring necessary information.

FIG. 14 is a flowchart showing the company information collecting process and the homepage information collecting process in this embodiment.

In this figure, steps 120 to 128 correspond to a company information collecting process. Step 1
The process from 34 to step 146 is the homepage information collection process.

First, in the company search information DB 32, URLs of sites providing company information for searching for companies of a large number of open procurers who publish procurement information via the Internet 1 are stored in advance. Have been. Such sites include regular search sites on the Internet,
It also includes sites established by publishers that traditionally publish information on the economic and business circles.

Referring to FIG. 14, first, the company information collecting process from step 120 to step 128 will be described.

In step 120, the company information collection unit 60 in the company information collection processing unit 42 accesses a site stored in the company search information DB 32 via the Internet 1. Then, in step 122, the company information providing site server device 16 of the site provides home page format information via the Internet 1. The information includes company information and other information is mixed. In step 124, the company information collection unit 6
0 accepts the information. In addition, information in the form of a home page includes HTML (hypertext markup language),
Includes those described in XML (extensible markup language).

In step 126, the company information DB updating unit 6
1 receives the information from the company information collecting unit 60, and extracts a company name and information (company information) used in the present embodiment regarding the company from the information. The information includes, for example, at least the U.S.
RL, and may further include information on the location of each company and performance. Step 126
Then, a data table (correspondence table) of the company name and the company information of each company is generated.

Note that the U extracted in step 126
The homepages of the RL companies are those that publish the procurement information or those that may be, and are provided by the procurement site server device 18 of each company.

In step 128, the company information DB updating unit 6
1 is a company information DB 33 based on the data table.
, A new company is added, and the URL of the company and other company information are registered. Alternatively, the company information DB updating unit 61 updates the URL and other company information of a registered company if any has been changed.

Next, referring to FIG. 14, a description will be given of the homepage information collection processing from step 134 to step 146.

In step 134, the HP information collection unit 63 of the homepage information collection processing unit 44 stores the URL of the site where the procurement information is disclosed or is considered to be disclosed for each company, in the company information DB 33. Read from Then, such a site is accessed via the Internet 1.

In the homepage of each site,
For example, as shown in FIG. 17, a plurality of pages exist in a hierarchical structure below the top page. In the present embodiment, such a plurality of pages are automatically accessed up to a layer of a preset depth.

In step 136, each company procurement site / server device 18 provides home page format information via the Internet 1 for the access. The information includes procurement information, and also includes other information. In step 138, the HP information collecting unit 63 receives the information.

In the following step 140, HP information DB updating section 64 receives the information from HP information collecting section 63 and determines whether the site actually provides procurement information for the information. To search for a character string.
For example, if a character string such as “procurement” or “procurement” is included in the information in the homepage format, there is a possibility that the site actually provides the procurement information. I do. In this way, in step 140, it is possible to obtain a result of the determination as to whether or not the information is providing procurement information based on such a search result. Next, in step 144, the HP information DB updating unit 64 stores the determination result in the company information DB 33.
Write to.

It should be noted that the search keyword in the above-described character string search is not limited to the character strings of “procurement” and “procurement”. For example, a search keyword of another character string may be used. Further, a character string indicating various kinds, for example, “steel material” or “shape steel” may be used. Alternatively, the character string search may be performed by combining a plurality of search keywords like a so-called search formula in a database search.

In this embodiment, step 1
According to 42 and step 146, the person in charge can make a judgment or check on the judgment result, and then write the judgment result in the company information DB 33. In step 142, the determination result in step 140 is notified to the person in charge by e-mail or the like. Also, in step 146, the person in charge makes a judgment or check on the notified judgment result, and thereafter, the person in charge determines whether or not the procurement information is provided by the person in charge in the company information DB 33. Write to.

In the company information DB 33, a list of sites that may provide the procurement information is formed by writing the determination result.

FIG. 15 is a flowchart showing the procurement-related information collection processing in this embodiment.

In this figure, the procurement-related information collection processing is from step 150 to step 168. The procurement-related information collection processing can be considered to be performed after step 144 or step 146 of the homepage information collection processing described above.

In step 150, the procurement-related information collection unit 66 of the procurement-related information collection processing unit 46 publishes the procurement information for each company, among the sites that are supposed to publish the procurement information. Are extracted, and a list is formed in which the potential sites and the individual URLs of these sites are described. In step 152, the procurement-related information collection unit 66 reads the URL from the list, and accesses such a site via the Internet 1.

In step 154, each company procurement site server device 18 provides home page format information via the Internet 1 for the access. The information includes procurement information, and also includes other information, and the format of the information differs from site to site. Step 1
At 56, the procurement-related information collection unit 66 receives the information.

In step 158, the procurement-related information collection unit 6
6 processes the received information so that subsequent processing is easy. Next, in step 160, for example, the information obtained from each company procurement site server device 18 is converted to HTML.
If it is based on XML, it is converted into XML based on the information stored in the conversion information definition DB. After that, in step 162, the format conversion unit 67 converts the format of the information according to the information stored in the conversion information definition DB 34, and converts the information into unified table format information regardless of the procurement information providing site. Convert.

In step 162, since the format is converted from the XML format, the conversion process can be performed easily and reliably. Some homepages are not XML, but the number of XML ones tends to increase today. If the information is procurement information of an XML homepage, the processing of step 160 is substantially omitted, and the processing efficiency is improved.

At step 164, the code conversion unit 68
According to the information stored in the code conversion definition DB 35, the name and the item code of the procured item are converted, and are converted into information of the unified procured item name and the procured item code regardless of the site of the procurement information providing source.

After the conversion, even if the source of the procurement information is different, it is possible to recognize the procured item by the unified format and the name of the procured item. Is also easy. Therefore, the information processed up to this stage can be used when making a bid or the like.

In step 166, the procurement difference information generation unit 6
9 reads out information on the procured item from the procured item DB 37 and compares it with the information obtained up to step 68. Then, new information or information having a change is extracted, and difference information of the procured item is generated. In step 168, the procurement difference information generation unit 69 updates the procurement item DB 37 based on the information obtained up to step 164 and the procurement item difference information obtained in step 166.

The above-mentioned procurement item difference information can recognize the procurement item by a unified format and the name of the procurement item regardless of the site of the procurement information providing source.
Further, since new procurement information and changed procurement information can be focused on, such information is useful for the judgment of a person in charge when making a bid or the like.

FIG. 16 is a flowchart showing the bid information collecting process in the present embodiment.

In this figure, the bid information collecting process is from step 170 onward. The procurement-related information collection process can be considered to be performed after step 168 of the procurement-related information collection process described above.

In step 170, the inventory DB comparison processing unit 73 of the bid management server device 14 reads out the procurement item difference information stored in the procurement item DB 37, and furthermore, checks the inventory of the procurement item included in the procurement item difference information. Contact The inventory inquiry is made to the inventory DB 30 in the host computer device 12 via the network 3.
Then, in step 172, the host computer device 12 reads necessary information from the inventory DB 30, and sends the information to the inventory DB comparison processing unit 73 via the network 3. In step 174, based on the stock information received from the host computer device 12, the stock of the procured product included in the procured product difference information is confirmed.

Thus, the inventory DB comparison processing section 73
In, among procurement items included in the procurement item difference information,
Information about items that are actually in stock and available for bid can be obtained.

In the subsequent step 176, the bidding-related information generation unit 74 processes the bidding-possible item information. In step 176, all or a part of the information is notified to the person in charge or the related system by e-mail or the like. For example, a notification is made by e-mail to a person in charge of using one of the client PC devices 10, or to another system such as a bidding-related procedure established in the host computer device 12.

At step 178, the bidding-related processing section 76 performs bidding-related processing. For example, a document for bidding is created regardless of a paper medium or an electronic medium. In this process, a person in charge of receiving a notification by e-mail as described above may be intervened, or the process may be automatically performed without any human element.

At step 180, the bidding information transmission processing section 7
In step 7, the document created in step 177 is sent. For example, in the case of using an electronic medium, the document is sent to each company's procurement site / server device 18 of the corresponding site via the Internet 1, and is accepted at the site in step 182.

The bid-related processing section 76 and the bid information sending processing section 77 may be constructed in the host computer device 12, or may be constructed in the bid management server device 14.

As described above, the present invention can be effectively applied to the present embodiment. Therefore, it is possible to reduce the cost, time, and labor for acquiring necessary information.

In the above description, the conversion information definition DB 34 and the code conversion definition DB 35 may be automatically generated. For example, the host computer device 12
DB30 in each company and each company procurement site server device 1
The automatic generation may be performed while associating the information obtained from step 8 with the information obtained from step 8.

In the embodiment described above, the externally provided information is used as the procurement information. The present invention is not limited to this, and can be similarly applied, for example, when the externally provided information is purchase information.

As described above, in the case of purchasing information, the wording “purchase” may be replaced with the wording “purchase” in the description and figures of this embodiment. In addition, the content of selling the procured product may be replaced with the content of purchasing the purchased product.
