- the present invention relates to an article data search server, an article data search method, an article data search program, and an article data search terminal device capable of reducing the processing delay caused by the sort processing that occurs and thereby efficiently searching for article data.
- Patent Literature 1 which sorts all cases searched from a database in descending order of similarity is known. This technique is widely used in addition to Patent Document 1.
- Patent Document 1
- Patent Document 1 if all the article data retrieved from the storage unit is sorted and the latest article data is narrowed down, such sorting takes time, and as a result, The problem arises that efficient search processing cannot be performed.
- the sort process is most affected by the number of pieces of article data. As the number of article data increases, the processing delay required to sort the article data increases and the search efficiency decreases. For processing other than the sort processing, the processing time does not necessarily increase as much as the sort processing depending on the number of article data.
- the present invention has been made to solve the above-described problems caused by the conventional technology, and reduces a processing delay caused by a sorting process that occurs when searching for article data such as newspapers and magazines. It is an object of the present invention to provide an article data search server, an article data search method, an article data search program, and an article data search terminal capable of efficiently searching data.

- article data having a corresponding keyword is extracted from article data having a date within a predetermined period. If the number of article data searched exceeds the specified number, the search is performed again while limiting the specified period, so that even if the search period is not specified, the search By performing the search again while shortening the search time, it is possible to reduce the processing delay caused by the sorting process that occurs when searching for article data such as newspapers and magazines.
- a search request including a search period as a search condition is received from a terminal device
- article data having a corresponding keyword is selected from the article data having dates within the search period.
- the search data is re-searched while limiting the search period.Therefore, the search is repeated while appropriately shortening the search period specified by the user. It is possible to reduce the processing delay caused by the sort processing that occurs when retrieving article data such as newspapers and magazines.
- the re-search is repeated until the number of article data is within the predetermined number while limiting the search period.
- the number of article data can be narrowed down to a predetermined number without fail, so that high-speed sorting can be achieved.
- the search start date when the number of searched article data exceeds a predetermined number, the search start date is shifted based on the number of days of the search period, the number of displayable article data on the terminal device, and the number of article data. Therefore, the search start date can be changed flexibly and appropriately according to the number of days of the search period, the number of displayable article data on the terminal device, and the number of article data.
- the search end date is shifted to shorten the search period, so that the search end date is flexible and appropriate according to the number of days of the search period, the number of displayable article data on the terminal device, and the number of article data. Can be varied.
- a search request specifying a keyword is made to an article data search server, and in response to the search request, the article data search server searches for a plurality of article data using a keyword, When the number of retrieved article data exceeds a predetermined number, the search result is obtained by re-searching article data while limiting the search period, and display control of the received search result is performed.

- FIG. 4 is a flowchart for explaining in more detail a procedure for creating a narrowing-down search formula in FIG. 4.
- FIG. 1 shows the system configuration of the article data search system according to the present embodiment.
- FIG. 4 is a functional block diagram showing As shown in FIG. 1, the article data search system has a configuration in which each of the terminal devices 10 a to 10 c and the web server 12 are connected via the Internet 11. ,
- Terminal device 10a is an Internet terminal equipped with a web browser that can access an HTTP server, and can access various server devices on the Internet via a provider or the like.
- the terminal devices 10a to 10c include a search request function for requesting the WEB server 12 to search for headline data of an article in which a keyword is specified, and a plurality of WEB servers 12 using the keyword.
- the WEB server 12 is an HTTP server that receives accesses from various terminal devices 10a to 10c on the Internet and provides web services such as homepages.
- the WEB server 12 not only provides general web services, but also stores headline data of articles of newspapers and magazines in the storage unit 123, and sends a search request for article data specifying a keyword to a terminal.
- article data corresponding to the keyword is retrieved from the storage unit 123 and output to the terminal devices 10a to 10c.
- the web server 12 does not sort all of the plurality of heading data retrieved using a key in the order of date as in the related art, but rather searches the number of heading data retrieved. If the number exceeds a predetermined number, the heading data is searched again while limiting the search period to reduce the number of headings, and then this heading data is sorted in chronological order to reduce the processing load associated with sorting. I have.
- the web server 12 has an interface unit 120, an input unit 121, a display unit 122, a storage unit 123, and a control unit 124.
- the interface unit 120 is connected to the terminal devices 10 a to 10 c via the Internet 11.
- This is a network interface that exchanges data with the network. Specifically, it performs processing in accordance with the TCP / Ip protocol.
- the input unit 121 is an input device such as a keyboard and a mouse
- the display unit 122 is a display device such as a liquid crystal panel and a display
- the storage unit 123 is a storage device such as a hard disk device. Since the storage unit 12 stores the hypertext 123a and the heading data 123b, the part storing the heading data 123b forms the heading database of the article.
- the hypertext 123a is hypertext 1, which forms a page screen to be distributed to the terminal device 10a to: L0c
- the heading data 123b is heading data of a newspaper or magazine article.
- the headline data 123b can be obtained online from a contracted newspaper or magazine server, or earned off-line using a medium such as a CD-ROM.
- the control unit 124 is a control unit that performs overall control of the web server 12 that provides headline data of articles, and includes a server processing unit 124a, a headline data search unit 124b, and a sort processing unit 124c.
- the server processing unit 124a is a processing unit for providing the terminal devices 10a to: L0c with a function as an HTTP server, and specifically, the terminal devices 10a to 10c.
- the hypertext 123a stored in the storage unit 123 is read out and transmitted to the corresponding terminal device 10a to 10c.
- the heading data search unit 124b searches the storage unit 123 for a plurality of heading data 123b using a keyword, and when the number of searched heading data exceeds a predetermined number, re-searches the heading data while limiting the search period. It is a processing unit that performs The reason for narrowing down the number of heading data by vigorous re-search is that the larger the number of heading data, the longer the processing delay of the sorting process by the sort processing unit 124c. . Specifically, for example, a search period of, for example, two years is set in advance, and if a search request that does not include the search period is received from the terminal device 10a to 10c, the search period is set to two years and the keyword is set. Search by.
- a search request in which a search period is specified in advance is accepted, and when the number of entries and the number of searched headline data exceeds a predetermined number, a similar search is performed while narrowing down the search period.
- the sort processing section 124c is a processing section that sorts the entry data 123b searched by the entry data search section 124b in chronological order. Since the heading data search unit 124b limits the number of heading data, it is not necessary for the sort processing unit 124c to sort a large number of heading data.
- the sorted heading data 123b is output as hypertext to the terminal devices 10a to 10c via the server processing unit 124c.
- FIG. 2 is a flowchart showing a processing procedure performed between the terminal device 10a and the web server 12 shown in FIG.
- the web browser is started on the terminal device 10a and the web server is accessed via the internet 11 (step S201)

- step S205 If the user inputs a keyword and a search period on this index search page 300 and instructs to start index search (step S205), the index search of the web server 12 is performed.
- the processing unit 124b executes a heading search process (step S206). If the user does not enter a search period, a headline search is performed with the specified period (for example, two years) as the search period. If the number of headline searches exceeds the specified number, the search period is narrowed down. A search is performed again.
- step S207 display data is created based on the index search result
- step S208 the terminal device 10a The display data is displayed above as a search result.
- FIG. 4 is a flowchart showing in more detail the execution procedure of the heading search process shown in step S206 of FIG.
- the heading data search unit 12 4 b of the web server 12 first initializes a variable 11 indicating the number of searches to 0 (step S 4 0 1), and then sets the terminal device 10 a Based on the keyword specified by ⁇ 10c, an initial search formula is created. (Step S402), the created search formula is used, and the heading data 1 2 A search process for searching 3b is performed (step S403).
- step S404 it is checked whether or not the number of hits of the heading data (the number of heading data) is within a predetermined number (step S404), and if it is within the predetermined number (step S404 affirmative), the sorting unit 1
- the heading data 1 23 b searched by the 24 c is sorted in order of date (step S405).
- Step S404 if the number of hits exceeds the predetermined number (No at Step S404), it is checked whether or not the variable n is within a predetermined number of times (Step S406), and the predetermined number of times is determined. If it exceeds (No at Step S406), the sort processing unit 124c sorts the heading data 123b searched by the first search expression in chronological order (Step S405). In other words, if it is powerful, the time required for narrowing down may take too much time due to the repetition processing. Therefore, the repetition is stopped at a certain number of times, and the sorting processing is performed based on the first search result.
- FIG. 5 is a flowchart for explaining in more detail the procedure for creating the narrowing-down search formula shown in step S408 of FIG.
- the heading data search unit 1 2 4 b of the web server 12 calculates the number of days d from the search start date to the search end date (step S 501), and then narrows down X is calculated (step S502).
- step S503 the product of the number of days d and the narrowing-down ratio X (dXx) is calculated as the number of shift days (step S503), and the date obtained by shifting the previous search start date by the number of shift days is set as the new search start date ( Step S504).
- a narrowing-down search formula is created by adding a period narrowing down based on the new search start date (step S505).
- the number of heading data can be reduced to a predetermined number or less before performing the sort processing by the sort processing section 124c, so that the processing delay required for the sort processing can be reduced.
- the coefficient for the maximum number of hits (1 or more) is X
- the coefficient for time narrowing (1 or more) is Y
- the display start position is pos
- the number of displays is max
- the search start date is start
- the search end date is Is the end
