BEST MODE FOR CARRYING OUT THE INVENTION

=== Call investigation device ===
As shown in FIG. 1, a DB management system that manages a well-known telephone number investigation history database is connected to a call investigation apparatus. As is well known, the call investigation device, as an example, classifies the use attribute of the number that is called as the telephone number into the following six types based on the reaction from the telephone network. The call investigation device determines that the number that is called corresponds to one of the following 6 types of classification, expresses the decision result by the following flag, and associates the telephone number and flag to be investigated Generated data (telephone number determination data).
● Invalid (unused number) ... Flag A
● Valid (call or communication available)… Flag B
● Relocation (with relocation announcement) ... Flag C
● Stop for convenience (calls not allowed) ... Flag D
● Departure from the station (calls not allowed)… Flag E
● Other (classification pending or review)… Flag F

  The method of classifying the usage attribute as a telephone number is a technical matter well known to those skilled in the art. Further, according to the purpose of the call investigation, the attribute classification is increased from the above six types and further classified. In addition, it is well known to roughly classify by reducing from six types. In this embodiment, the above six types of classification are used for easy understanding, and this method can meet the demands of most survey clients.

=== Investigation history database ===
As described in detail in References 1 to 5 described as background art, in the field of computing for investigation / utilization of telephone number usage, a set of numbers that may be used as telephone numbers is targeted. The above-described call investigation is periodically and repeatedly executed on a large scale, and the history of the telephone number determination data as a result of execution is stored in a database.

  The survey history database of the present invention is created in this way. In this embodiment, in the survey history database, the results of monthly call surveys of survey target telephone numbers (a set of all numbers that can be used as telephone numbers) are accumulated for the latest 24 months. ing. That is, for each of the numbers, 24 usage attribute classification flags (flag A to flag F), which are the investigation results for 24 months, are recorded in time series. According to the present invention, correspondence information of a telephone number and a corporate number investigated as follows is added to the investigation history database.

=== Look up the phone number based on the Corporate Number Basic 3 Information ===
As shown in FIG. 1, the system for carrying out the computing method of the present invention is connected to the above-described telephone number investigation history DB management system and to the Internet. The storage system of this system stores the latest list of corporate number basic 3 information acquired from the corporate number publication site of the NTA, and each corporation uses it based on this corporate number basic 3 information list as follows. A program for examining a telephone number (telephone number extraction processing program) runs. Although not shown, this system is equipped with a user interface device including a keyboard and display so that the person in charge can give instructions to the system and receive output of processing results. It has become.

  An outline of the telephone number extraction process is shown in the flowchart of FIG. This system reads one record from the corporate number basic 3 information list. It is assumed that the corporate number A, the corporate name B, and the location C are recorded in the record. This system makes an inquiry to a search engine (for example, Google search engine) on the Internet using the corporate name B as a search word, and acquires a search result from the search engine.

  As is well known, in the search result report (HTML document) from the search engine, URLs of a large number of websites that have hit the search term are listed together with their summaries in a predetermined manner. In the telephone number extraction process of this embodiment, the HTML document of the search result report is automatically analyzed, and the process of searching for the target telephone number from the first website in the report is started. The processing proceeds with the website and the third website, and when the target telephone number cannot be found from the fifth website, it is determined that the extraction of the telephone number has failed.

  As shown in FIG. 2, first, n is set to 1, and the URL of the first website in the search result report is transmitted to the Internet to obtain the corresponding web page. From the HTML description of the web page, an article part including the description of the location C, which is one of the corporate number basic 3 information, is found, and a number (the most significant digit) that may be used as a telephone number from the article. The process of finding a 10-digit number of 0) is executed.

  If it is a general corporate website, in many cases the company's location is listed in an article titled "Company Profile" or "Company Information", and a telephone number is written nearby. ing. Therefore, by analyzing the corresponding web page according to the above processing procedure, in many cases, the telephone number of the corporation corresponding to the corporate name B and the location C can be found, and the telephone number is converted to the corporate number A. It can be extracted as a corresponding phone number.

  As mentioned above, even if the target phone number cannot be extracted from the web page from the first website in the search result report, the same process is repeated up to the fifth website, so that the probability is quite high. The target telephone number can be extracted. However, the target telephone number cannot be extracted by the above-described processing for all the corporate numbers to be investigated, and in this case, the processing result is a telephone number extraction failure.

  When a plurality of telephone numbers are found in the article by the above-described telephone number extraction process, the program is designed to extract one telephone number described at a higher position in the article. In other words, if two phone numbers are listed in two upper and lower rows, the upper phone number is extracted, and if two phone numbers are placed left and right, the left phone number is extracted. .

=== Recording correspondence between corporate number and telephone number ===
As shown in FIG. 1, in the system, the telephone number D extracted by the survey and the telephone number D extracted by the survey are associated with the correspondence information of the corporate number A, the corporate name B, and the location C that is the subject of the survey. Data that further associates the URL of the website from which the number D is extracted with the survey date is recorded in a predetermined table created in the storage device. It will be obvious to those skilled in the art that this table is utilized separately from the telephone number search history database.

  In addition, this system communicates with the telephone number investigation history DB management system in a timely manner, and based on the correspondence between the corporate number and the telephone number obtained by the telephone number extraction process described above, the telephone number of each record in the telephone number investigation history database In addition, the correspondence information between the corporate number and the telephone number is combined. For example, the corporate number A is added to the record of the telephone number D in the telephone number investigation history data. Further, the corporate number A, the corporate name B, and the location C are added to the record of the telephone number D, and the URL and the survey date from which the telephone number D is extracted are added.

  The NTA regularly updates the corporate number basic 3 information list on the corporate number publication site. In accordance with this, the present system is also programmed to periodically perform telephone number extraction processing based on the latest corporate number 3 information list. As is clear from the above description, the scope of the present invention extends to a computing system programmed to implement the computing method as well as a computer program for implementing the computing method. is there.

=== New usage of the advanced phone number search history database ===
As described above, the telephone number search history database according to the present invention in which the corporate number basic 3 information is combined with the telephone number can be used in various ways as conventionally disclosed in References 1 to 5, for example, new It can be used as follows.

(A) It is determined whether the combination of the corporate name and the telephone number written in the application submitted by the user is correct.
(B) The telephone number history is confirmed from the corporate number or corporate name, thereby obtaining corporate credit information.
(C) Confirm the transfer information of the telephone number from the corporate number or corporate name, thereby quickly knowing the corporate transfer.
