[Prior art]
With the spread of the Internet, the opportunity to search for necessary information from the Internet tends to increase. When searching for necessary information, access a search site and enter a search keyword related to the required information to perform a search. However, the amount of information on the Internet is enormous, and a large amount of data (web page) hits a search keyword in many cases. When there is a large amount of hit data (hit pages), it becomes necessary to reconsider the search keyword or to repeat the search many times.
[0003]
Some search sites add a score (or point) uniquely calculated by the search site to each hit data (hit page) so that the user can browse the hit data with reference to the score. There are places. The score is determined by each search site independently, for example, based on the number of search keywords in the hit data or based on the number of links to the hit data.In general, the higher the score, the higher the score In many cases, the information is closely related to the search keyword.
[0004]
Also, there is a method of assisting the input of a search keyword by creating a database of search keywords input in the past and displaying a search keyword candidate list that matches forward with the character input by the user (for example, see Patent Document 1). .

The search system 20 that has received the search keyword from the information processing device 10 transmits a hit data list that is a list of hit data that has hit the received search keyword to the information processing device 10. The hit data list received by the communication unit 17 from the search system 20 (S42) is stored in the RAM 12 under the control of the CPU 11.
[0052]
The CPU 11 extracts the highest score of the hit data list stored in the RAM 12, stores the highest score in the RAM 12, compares the extracted highest score with the desired score, and if the highest score is equal to or more than the desired score (S44: YES), the score is Hit data having a desired score or higher is extracted (S46), and it is determined based on the hit data information whether or not the URL of the extracted hit data is new. If the URL is new (S48: YES), the CPU 11 stores various information related to the extracted hit data in hit data information (however, the new arrival flag is "1") (S50).
[0053]
When the extracted hit data is stored (S50), when the highest score is lower than the desired score (S44: NO), or when the URL is not new (S48: NO), the CPU 11 refers to the keyword information and performs other processing. The presence or absence of the search keyword is determined. When there is another search keyword (S52: YES), a similar search process is performed. When there is no other search keyword (S52: NO), the CPU 11 outputs a list of new hit data (new arrival flag = “1”) from the communication unit 17 to the user terminal 24 (S54). The CPU 11 updates the new arrival flag of the output new hit data to “0”.
[0054]
FIG. 10 shows an example of an output screen of the extracted hit data. In the example shown in FIG. 10, a search keyword and a desired score included in the keyword information, and a title, a score, and a URL of the extracted hit data (HTML data) included in the hit data information are displayed.
[0055]
In the above-described third embodiment, the communication unit 17 of the information processing apparatus 10 receives various settings related to user information and keyword information from the user terminal 24, and outputs new arrival information to the user terminal 24 from the communication unit 17.

[0057]
In this description, an example will be described in which HTML (Hyper Text Markup Language) data constituting a website on the Internet is searched. Each hit data (HTML data) has a URL (Universal Resource Locator), a title, and a text (display character portion). In the present embodiment, the hard disk 13 stores hit data information including the address, text (content information), and search keyword of each hit data included in the hit data list received from the search system 20 by the communication unit 17. Act as a unit.
[0058]
FIG. 12A shows an example of hit data information. The hit data information includes, for example, hit data No for identifying hit data, URL of hit data (HTML data), title of hit data, search keyword used for search of hit data (may be a combination of plural keywords), hit It includes the score of the data and the text of the hit data. The “URL”, “title”, “search keyword”, “score”, and “text” of the hit data information can be updated by the CPU 11 based on the hit data list received from the search system 20, for example.
[0059]
The communication unit 17 operates as a unit that receives a URL (address) of hit data (HTML data) from the user terminal 24 connected to the communication network 22, and the CPU 11 responds to the hit data of the URL received by the communication unit 17. It operates as a means for reading out text (content information) and a search keyword to be performed from the hard disk (hit data information) 13 and a means for transmitting the read out search keyword from the communication unit 17 to the search system 20.
[0060]
Further, the CPU 11 operates as means for detecting, from each hit data included in the hit data list received from the search system 20, hit data whose text (content information) is similar to the read text (content information). The information on the detected hit data is stored in the hard disk 13 (URL change information), and is output from the communication unit 17 to the user terminal 17. FIG. 12B shows an example of the URL change information. The URL change information includes the hit data No. of the hit data of the URL received by the communication unit 17 from the user terminal 24, the URL of the hit data detected (candidate URL), and the title.
[0061]
By reading out the computer program recorded on the recording medium 19 such as a CD-ROM in the external storage unit 14 and storing it in the hard disk 13 or the RAM 12 and causing the CPU 11 to execute the same, the CPU 11 can operate as the above-described units. is there. Further, the communication unit 17 can receive a computer program from another device and store the computer program in the hard disk 13 or the RAM 12.
[0062]
Next, a data search using the information processing apparatus according to the present invention will be described.
The CPU 11 transmits the search keyword received from the user terminal 24 by the communication unit 17 to the search system 20 from the communication unit 17, and information on each hit data (HTML data) in the hit data list received from the search system 20 by the communication unit 17. And the search keyword are stored in the hit data information. FIG. 13 shows an example of a procedure for searching for a URL that has become inaccessible.
[0063]
When the communication unit 17 receives the URL that has become inaccessible from the user terminal 24 in the communication unit 17 (S60), the CPU 11 reads various information such as a search keyword and a text related to the received URL from the hit data information (S62), and stores it in the RAM 12. Remember. When the search keyword corresponding to the received URL is read (S64: YES), the CPU 11 transmits the read search keyword from the communication unit 17 to the search system 20, and receives a hit data list from the search system 20 (S66). ). If the search keyword has not been read (S64: NO), the process ends.
[0064]
The hit data list received by the communication unit 17 from the search system 20 is stored in the RAM 12 under the control of the CPU 11, and a candidate URL is extracted (S68). For example, the CPU 11 extracts the text of each hit data in the received hit data list, stores the text in the RAM 12, and extracts hit data whose text is similar to the read text from the hit data of the received URL. Text similarity can be determined to be similar if the proportion of character matching portions in the text is greater than or equal to a predetermined value.
[0065]
If there is a candidate URL (S70: YES), the CPU 11 stores information on the candidate URL in the URL change information of the hard disk 13, and outputs the information from the communication unit 17 to the user terminal 24 (S72). If there is no candidate URL (S70: NO), the process ends. FIG. 14 shows an example of an output screen of information on the candidate URL. In the example of FIG. 14, the URL received from the user terminal 24 by the communication unit 17, the title and search keyword of the hit data corresponding to the received URL, and the candidate URL and title are displayed.
