[0002]
In addition, the present invention relates to a program for causing a computer to perform the processing in such an information collection method.
[0003]
[Prior art]
In recent years, a user can search for target information via the Internet using a terminal such as a mobile phone or a PC, and browse the target information based on the search result displayed on the terminal. When searching for the target information, the user searches for the target information by using a search function on various portal sites operated by an information manager (provider) using a terminal on the user side. At this time, when a keyword is input to the input field from the user's terminal and the search for information is started, the information providing server of the provider uses a crawler or a spider, which is a program dedicated to collecting content information, to execute the search based on the keyword. Content information is collected and analyzed. The information providing server manages a database (hereinafter, referred to as a DB) called a search index from the collected content information, and provides the search index to a user terminal as a search result. The user can browse target information by displaying the search index on the terminal.
[0004]
In the information providing server, the frequency of collecting the content information and the like can be arbitrarily set and changed according to the purpose. For example, when the content information to be collected is news provided by a newspaper company, it is necessary to collect information at a high update frequency, so that the information is preset to be collected at intervals of about 10 minutes.
[0005]
Also, various methods have been used for the purpose of improving the convenience of a user performing a search so that useful information required by the user is displayed as high as possible. For example, by adding a ranking that takes into account the number of keywords appearing in the text of the content information, the importance of the keywords, and the ratio of links from other sites (importance due to linked sites), and displaying them in search results, The person can immediately browse the target information.
[0006]
In addition, in the information providing server, since a user inputs millions of keywords for a search in a day, many keywords related to the content information whose number of searches has rapidly increased are aggregated within a predetermined period, so that a large number of keywords can be obtained. It is possible to know what kind of keywords users are paying attention to.
[0007]
Further, the information providing server can efficiently provide the information required by the user by changing the order of the search results based on information such as the product inventory of the collected content information and the service closing.

[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016]
FIG. 1 shows a system configuration diagram in an information collection method according to an embodiment of the present invention. In FIG. 1, an information providing system 10 in an information collecting method is a system including an information providing server 20 for providing searched information to a user, a user terminal 50 for requesting a search for information for a keyword, and the like. is there. In FIG. 1, an information providing server 20 is a server computer, and each component is controlled by a CPU (Central Processing Unit). The CPU performs a process according to the information collection method according to a program stored in the memory unit. The information providing server 20 and the user terminal 50 are connected via the network 1.
[0017]
The information providing server 20 mainly includes a search information providing processing unit 30 that provides the searched information to the user side terminal 50, and a priority adjusting processing unit 40 that adjusts the priority and the like for the input keyword. ing. The search information provision processing unit 30 includes an installer 11 for installing a program for executing a process according to the information provision method, a display control processing unit 12 for controlling data display, a communication control processing unit 13 for controlling data communication, An input / output control processing unit 14 for controlling data input / output; a scenario DB 31 in which scenario information for the content information is stored; a content DB 32 in which the content information is stored; Unit 33, an indexer 34 for generating a search index for content information, an intelligent sorter unit 35 for sorting content information in order based on scenario information, a search DB 36 for storing a search index for content information, Search by receiving keyword from terminal 50 Performs management, and a search processing unit 37 to transmit the search results to the user terminal 50.
[0018]
The display control processing unit 12 has a display unit such as a display, and controls display data to cause the display unit to display the data. The input / output control processing unit 14 controls input units such as a mouse and a keyboard, and output units such as a printer, and controls input and output of data. The communication control processing unit 13 is a processing unit that controls transmission / reception data via the network 1 and has a communication unit for connecting to a network. The installer 11 reads the program from the recording medium 60 on which the program for realizing the information collecting method according to the embodiment of the present invention is recorded, and installs the read program in, for example, an auxiliary storage device.

The recording medium 60 may be any medium that can store a program such as a CD-ROM and is readable by a computer.
[0019]
The scenario DB 31 includes information for the information providing server 20 to classify information that the information providing side preferentially provides to the user or content information that the user of the information providing side wants to reduce the priority and avoid providing to the user. Are stored in advance. Note that the scenario DB 31 is independent of the search DB 36 (48a to 48n), and stores the priority (weight) determined for each search condition on a document basis for the search result. The scenario DB 31 will be described in detail with reference to FIG.
[0020]
The content DB 32 stores the content information collected by the priority adjustment processing unit 40. Note that the content DB 32 may store content information in the intranet, or may store content information collected by the collection processing unit 450. For example, if the content information is an E-commerce site, it is possible to store product information (product name, price, stock quantity, etc.) in the content DB 32.
[0021]
The check processing unit 33 checks the inventory, the deadline, and the like in the content information stored in the content DB 32. When the merchandise information is managed by the content Db32 as described above, the weight of the content information is determined by checking the recommended information and the stock quantity, and the same format as the table stored in the scenario DB 31 ( <Doc-ID, Point>) and stored in a DB provided between the check processing unit 33 and the intelligent sorter unit 35 (not shown). For example, in the case of general Web content collected in an intranet, date information is extracted by a method such as pattern matching, and a weight is determined based on the extracted date and the current date (the weight of the content of the latest future is Heaviest), converted to <Doc-ID, Point> format and stored in the DB.
[0022]
The indexer 34 generates a search index for the content information stored in the content DB 32. The intelligent sorter unit 35 receives the search index stored in the search DB 36 (48a to n), and sets the priority based on the scenario information stored in the scenario DB 31 and the content information checked by the check processing unit 33. , And sorts them in order, and supplies the results to the search processing unit 37 as final sort results. For example, in the intelligent sorter unit 35, the search index stored in the received search DB 36 (48a to 48n) is in the form of <Doc-ID, Point>, but Point has a predetermined default value. Is stored. The default value may store the value of TF / IDF calculated by the search processing unit 37, the number of links, and the like. Also, a search index in the form of <Doc-ID, Point> is stored in a DB (not shown) corresponding to the condition part of the scenario DB 31, or provided between the check processing part 33 and the intelligent sorter part 35. When the search index corresponds to the searched information, the search index is updated to the corresponding Point value.
[0023]
The search DB 36 stores a search index from the indexer 34. The search processing unit 37 performs a search process based on the keyword input from the user-side terminal 50 and the search index from the intelligent sorter 35, and transmits a search result to the user-side terminal 50.
[0024]
For example, when the search processing unit 37 receives a search request from the user terminal 50 (step S1), based on the input keyword, a search index to which a priority from the priority adjustment processing unit 40 has been added, Search processing is performed using the search index from the search DB 36. The search result is once supplied to the intelligent sorter unit 35 (step S2), and the search processing unit 37 transmits the search result sorted by the intelligent sorter unit 35 to the user terminal 50.
[0025]
The priority adjustment processing unit 40 includes a search log 41 that stores the history of the search index transmitted to the user side terminal 50 by the search processing unit 37, a priority calculation processing unit 42 that calculates the priority for the keyword, A priority DB 43 for storing priority information, a collection information control processing unit 45 for collecting content information based on a keyword having a priority, and a distribution based on priority, and a content collected based on the priority. It has collection DBs 46a-n for storing information, indexers 47a-n for generating search indexes for content information based on the collection DBs 46a-n, and search DBs 48a-n for storing search indexes from the indexers 47a-n.
[0026]
The search log 41 stores the history of the search index transmitted to the user terminal 50 by the search processing unit 37 and supplies the keyword to the priority calculation processing unit 42. The priority calculation processing unit 42 calculates the priority based on the keyword and the search result from the search processing unit 37, and supplies the priority to the priority DB 43. In addition, the priority calculation processing unit 42 supplies the priority of the content information to the priority DB 43 together with the characteristics of the content to be preferentially processed at the time of content collection, such as documents.
[0027]
For example, the priority calculation processing unit 42 calculates the priority based on the following three conditions. First, a higher priority is given to keywords and contents for which a search request from the user terminal 50 has increased in a short period of time, and second, a higher priority is given to keywords and contents with a small search result. Third, the priority is increased with respect to keywords and contents for which the user does not frequently browse the search results (the click rate is low). For example, the priority calculation processing unit 42 calculates the priority according to (the number of searches in the period Short_Time / the number of searches in the period Long_Time) × (1 / the number of search results) × (1 / the click rate of the search result). When the number of search results and the search result click rate are 0, a value between 0 and 1 is substituted. The click rate is calculated by embedding a URL to be embedded in a document displayed as a search result on the search result screen as an argument to a CGI (Common Gateway Interface) for calculating a click rate. The information of the document selected by the user from the search result screen in which the URL is embedded is collected as a part of the search log by CGI, and the URL of the target document is converted to the user terminal by the redirection processing function of the browser. 50 is displayed.
[0028]
The collection information control processing unit 45 collects the content information via the network 1, adds a priority to the content information and supplies the content information to the distribution processing unit 452, a collection queue 453, A control processing unit 451 that controls the collection processing unit 450 based on the priority information stored in the degree DB 43; a distribution processing unit 452 that distributes content information based on the priority; A collection queue 453 in which information for collecting content information is stored. The collection queue 453 stores URLs of content information in order of priority. When the priority of the collected content information is high, the collection processing unit 450 directly supplies the content information to the indexer 47a. In the collection DBs 46a to 46n, of the content information from the distribution processing unit 452, content information having a priority within a predetermined range is stored. The indexers 47a-n generate search indexes based on the content information stored in the collection DBs 46a-n, and supply the search indexes to the search DBs 48a-n. The search DB 36 (48a-n) will be described in detail with reference to FIG.
[0029]
Next, a processing procedure in the priority calculation processing unit 42 will be described. FIG. 2 is a flowchart for explaining the priority calculation process. First, in the processing of step S10, the priority calculation processing unit 42 determines whether the priority calculation processing has been completed based on the keyword and the search result from the search processing unit 37. If the priority calculation processing is not completed in the processing of step S10, the priority calculation processing unit 42 determines the priority key having the highest priority among the keywords and the search results from the search processing unit 37 in the processing of step S11. Take out.
[0030]
In the process of step S13, the priority calculation processing unit 42 determines whether or not the extracted priority key is included in the anchor character string or the URL character string. If the priority key is included in the anchor character string or the URL character string in the process of step S13, the priority calculation processing unit 42 determines the priority of the priority key in the content information document priority in the process of step S14. And stored in the priority DB 43. In the process of step S15, the priority calculation processing unit 42 inserts the search information to which the priority is added into the collection key 453 so that the information with the higher priority is first out. If the priority key is not included in the anchor character string or the URL character string in the processing in step S13, the processing from step S10 is repeated. When the priority calculation processing is completed in the processing of step S10, the priority of the document of the content information is set to 0 in the processing of step S12, and the processing of step S15 is performed.
[0031]
Therefore, when the priority of the URL with the highest priority in the collection queue 453 is equal to or less than a predetermined priority (Min-Priority), the priority calculation processing unit 42 recalculates the priority. To sort the collection queue 453. Thereby, a search result to which a priority according to a real-time situation change is added can be obtained.
[0032]
Next, a processing procedure by the collection information control processing unit 45 will be described. FIG. 3 is a flowchart for explaining the collected information control processing. First, in the process of step S20, the control processing unit 451 of the collection information control processing unit 45 initializes the content information collection process (Loop = 0). In the process of step S21, the control processing unit 451 selects the URL of the content information having the highest priority from the collection key 453. In the process of step S22, the control processing unit 451 determines whether the priority of the selected URL is equal to or higher than a predetermined priority (Min-Priority). If the priority of the selected URL is not equal to or higher than the predetermined priority in the process of step S22, the control processing unit 451 determines whether or not Loop = 1 in the process of step S23.
[0033]
If the priority of the selected URL is equal to or higher than the predetermined priority in the processing of step S22, or if Loop = 1 in the processing of step S23, the control processing unit 451 performs the processing of step S24 by using the collection processing unit. Provide URL to 450. If Loop = 1 is not satisfied in the process of step S23, the control processing unit 451 sets Loop = 1 in the process of step S25. In the process of step S26, the control processing unit 451 recalculates the priority based on all the URLs in the collection key 453 and the priority stored in the priority DB 43, and sorts the collection keys 453 in order of priority. , The processing from step S21 is repeated.
[0034]
In the collection information control process, a priority key having a lower priority at the time when the priority key is stored in the collection key 453 may have a higher priority as time passes thereafter. It is also possible to set to perform the calculation.
[0035]
It is assumed that the predetermined priority (Min-Priority) used in the priority calculation processing and the collection information control processing is read when the processing is started.
[0036]
Next, information stored in the priority DB 43 will be described. FIG. 4 is a diagram illustrating a table stored in the priority DB. In FIG. 4, a table 430 stores information such as a priority of a keyword input from the user terminal 50. The table 430 includes a priority key ID for identifying a priority key, a priority key check item indicating an item to be checked for the priority key, a priority key input from the user terminal 50, and a priority corresponding to the priority key. Is stored. For example, the priority key check item includes a keyword in the body of the document of the content information, a character string in the URL, an anchor character string of a link source, and the like.
[0037]
Next, information stored in the priority DB 43 will be described. FIG. 5 is a diagram illustrating a table stored in the priority DB. In FIG. 5, a table 431 stores information about each index 34 (47a to n) set in advance by an administrator of the information providing server 20 or the like. The table 431 stores an indexer ID indicating an identifier for each of the indexers 47a to 47n, the maximum value of the priority of the document of the content information assigned to the indexer, and the minimum value of the priority of the content document assigned to the indexer. .
[0038]
Next, information stored in the collection DBs 46a to 46n will be described. FIG. 6 is a diagram illustrating a table stored in the collection DB. In FIG. 6, a table 460 stores information on content information sorted by priority by the sorting processing unit 452. The table 460 stores a URL_ID indicating an identifier for each URL, a URL of a collected document, an indexer ID assigned according to a priority, a date and time when the content information was collected, and the content of the collected document. Is done.
[0039]
Next, information stored in the search DB 36 (48a to 48n) will be described. FIG. 7 is a diagram illustrating a table stored in the search DB. In FIG. 7, a table 360 stores information on search results from the indexers 34 (47a to 47n). The table 360 stores a search term searched based on a keyword and an ID list of a document of content information including the search term.
[0040]
Next, information stored in the search DB 36 (48a to 48n) will be described. FIG. 8 is a diagram illustrating a table stored in the search DB. In FIG. 8, a table 361 stores information for each document as a search result from the indexer 34 (47a to 47n). The table 361 stores a document ID indicating a document identifier, a title of the document corresponding to the document ID, a URL of the document, a summary of the document, and a date and time when the document was collected. The information for each document ID stored in the table 361 is searched by the search processing unit 37 and provided to the user terminal 50.
[0041]
Next, information stored in the scenario DB 310 will be described. FIG. 9 is a diagram illustrating a table stored in the scenario DB. In FIG. 9, a table 310 stores scenario information set by an administrator of the information providing server 20 or the like. The table 310 stores <condition part> and <document ID, point>(<Doc-ID,Point>) as one record. For example, when the <condition part> is <document ID>, if there is a document with the document ID in the search result, the weight for other documents is determined. When <condition part> is <keyword>, the weight of the document ID in the result searched by <keyword> (search formula) is determined.
[0042]
For example, when the keyword “broadband” is input from the user terminal 50, the information providing server 20 provides the user terminal 50 with a search result based on the keyword and the table 310 of the scenario DB 31. . At this time, the search result 1. "What is broadband?" “About various services of broadband”, 3. "Various service contract information" is displayed. By tracing the content information from the search results displayed on the user terminal 50, the user can understand the outline of broadband and know how to receive various services. In addition, since search results that reflect the intention of the information provider can be provided to the user side, a scenario-like method of navigating to the target content information, and inventory information when product or ticket information is searched, It is also possible to adapt to a method of providing recommended content information in consideration of the date and deadline.
