Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides information about a keyword input to search a target homepage by a search engine of the Internet, a keyword input to a computer connected to a network, and other information. The present invention relates to a method and method for notifying a person who needs the information.

[0002]

2. Description of the Related Art On the Internet, a user of the Internet often uses a search engine on the Internet to search for a desired home page. By using the search engine, it becomes possible to search for a desired homepage from the huge number of homepages held by the huge number of WWW (World Wide Web) servers connected to the Internet.

For example, when I want to go to see a movie of a certain title on a weekend, but when I don't know the movie theater and the show time of the movie, I have conventionally searched newspapers and information magazines. On the other hand, on the Internet, you can enter the specified title in the keyword input field on the homepage for using a search engine and press the search button to display the homepage of the movie theater showing the movie and the movie. It is possible to obtain a screen of a list such as a homepage managed by the movie theater that is showing. The user can obtain the screen of the home page by hyperlink by simply clicking the name of the home page in the list. If the screening schedule is posted on the screen, the user can know the movie theater in which the movie of the title is shown and the show time.

In this way, the keywords for each user to search the homepage are input to the keyword input field of the search engine.

The input keyword is a CGI (Common Gateway Interface) program of a WWW server that stores a home page for using a search engine and a CG.
The summation is taken by the program called from the I program. From the aggregated contents, for example, a ranking of the keywords input each week is generated, and is posted in, for example, a computer-related magazine. Further, the ranking may be generated for each genre, and for example, the ranking of movie titles for each week can be generated.

[0006]

[Problems to be Solved by the Invention] However, conventionally, although the ranking of keywords is taken and published in magazines and the like, there is almost no disclosure of more information to the society, and the ranking is at most the previous ranking. Was only compared.

By the way, depending on the industrial field, there are cases where the trend of keywords popular in society is checked and the future product or service or the technology to be developed is determined based on the trend. Then
We were unable to handle such cases. In other words, in order to decide which products and services will become popular in the future, it is necessary to know what has a trend, but those that have risen to the top of the ranking are already in fashion and will end in the near future. Often there is.

Further, even if a new keyword appears, it is uncertain whether or not the keyword will become popular. Therefore, it is necessary to monitor the change in the number of searches for the new keyword.

[0009] Further, if the manufacture of goods is stopped after the end of the fashion, it will result in excess inventory, but it is difficult to predict the end of the fashion from the higher rankings. It is difficult to prevent such a situation.

The present invention has been made in view of the above problems, and by notifying the user of the change in the keyword, the keyword information notifying system that enables the user to know the signs of the change in the fashion. And its method.

DETAILED DESCRIPTION OF THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

[First Embodiment] FIG. 1 is a conceptual diagram showing the overall configuration of a system according to the first embodiment.

Referring to FIG. 1, this system includes a terminal 1
01-1, 101-2, 101-n, a WWW server, and the Internet 103 connecting these are provided. Although there are only three terminals in FIG. 1, there are actually many other terminals.

The WWW server 102 is a site that provides a homepage search service by a search engine, and is provided to the WWW browsers installed in the terminals 101-1, 101-2, and 101-3 by this WWW server. If you enter the address of the homepage, http (Hyp
er-Text Transfer Protocol), the home page is transmitted from the WWW server 102 to the terminals 101-1, 101-.
2, 101-3, and the screen is displayed on the displays of the terminals 101-1, 101-2, 101-3 as shown in FIG.

When the user of each terminal inputs a keyword in the keyword column 301 and presses the search button, a homepage having the keyword in the title or the like is searched by the search engine, and a homepage having such a list of homepages is found in each terminal. And the home page is displayed on the display of each terminal.

FIG. 3 is a block diagram showing the configuration of the keyword information notification system according to the embodiment of the present invention.

The present system uses the keyword input means 201, the keyword file 202, and the trigger information input means 20.
3, counting means 204, counting result file 205, new keyword detecting means 206, range deviation keyword detecting means 2
07, the notification means 208 is provided.

The keyword input means 201, trigger information input means 203, totaling means 204, new keyword detecting means 206, range deviation keyword detecting means 207, and notifying means 208 are CPUs (not shown) of the WWW server 102.
However, it can be realized by reading a program (CGI program, general program, etc.) for causing the WWW server 102 to function as these means from a recording medium (magnetic disk device, etc.) and executing the program. In addition, the keyword input means 201, the aggregation means 203, the trigger information input means 205, the new keyword detection means 206, the range deviation keyword detection means 207, and the notification means 208 are W
It can also be realized by the CPU of the WW server 102 receiving and executing a program for causing the WWW server 102 to function as these means via the Internet 103. Keyword file 202,
The counting result notification file 204 is recorded on the recording medium.

The keyword input means 201 inputs the keyword input from the WWW server 102 into the keyword input field 301, and sequentially writes it to the keyword file 202 with the date and time when it was input. Therefore, the keyword file 202 stores the keyword and the date and time when it was input as a set. Keyword file 20
2 may have a database format having keywords and dates as fields.

The trigger information input means 203 inputs trigger information from the notified person. Here, the notified person is
A person who is scheduled to receive notification information by the notification means 208. Trigger information can be entered by e-mail, the information entered in the form on the home page for entering trigger information can be sent from the terminal to the WWW server, can be sent by mail, etc. Can be used. The trigger information includes an aggregation period, a detection target keyword list, a change degree range, and notification destination information. The counting period is the counting means 2
04 is a unit period for totaling keywords,
For example, one week, one month, etc. are selected. The detection target keyword list is the range deviation keyword detection means 207.
Is a list of keywords to be detected when the range deviation keyword is detected. The degree-of-change range is the minimum value (negative number) of the degree-of-change range when the degree-of-change is defined as the degree-of-change = the number of inputs in the current aggregation period-the number of inputs in the previous aggregation period.
And the maximum value (the number of positives), and the degree of change is defined as the degree of change = (the number of entries in the current aggregation period-the number of entries in the previous aggregation period) / the number of entries in the previous aggregation period , The minimum value (negative percentage) and the maximum value (positive percentage) of the variation range. The notification destination information is information for specifying the notification destination of the notification information, and is, for example, the email address or address of the notified person.

The totalizing means 204 uses the keyword file 2
02 based on the content of 02 and the total period input from the trigger information input unit 203, for each same keyword recorded in the keyword file 202 and for each period designated by the total period input from the trigger information input unit 203,
The number of times the keyword is input is totaled, and the totalized result is written in the totalized result file 205. Therefore, the tabulation result file 205 stores the keyword, the period, and the number of inputs as a set. The keyword file 202 may have a database format having keywords, a period, and the number of inputs as fields.

Based on the contents of the totaling result file 205, the new keyword detecting means 206 does not input in any past totaling period, and is newly input during the present totaling period, that is, totaling result file 205. In any of the past totaling periods, the keyword recorded as a keyword input once or more during the current totaling period is detected, and the detected keyword is output to the notifying unit 208. Since the totalization result file 205 has a finite capacity, the fact that it is not recorded for any past totaling period means that it is not recorded for any finite past totaling period. Also, instead of entering the keyword newly entered in the current aggregation period without being entered in any past aggregation period, it is newly entered in the current aggregation period instead of being entered in the past specified number of aggregation periods. You may detect the keyword. For example, a keyword newly input this month without being input in the past 10 years may be detected. The past 5 years, the past 3 years, and the past 1 year may be used instead of the past 10 years.

The range deviation keyword detecting means 207 detects a keyword whose change degree deviates from the change degree range based on the contents of the aggregation result file 205, the search target keyword list inputted from the trigger information input means 203, and the change degree range. Then, the detected keyword and its degree of change are output to the notification unit 208. The degree of change is as defined above. By limiting the search target to only the keywords in the search target keyword list, the keywords to be searched can be narrowed down and the interest of the notified person can be reflected. However, if the notified person cannot narrow down the keywords of interest, the search target may be all the keywords recorded in the aggregation result file 205.

The notifying means 208 notifies the notified person of the keyword inputted from the new keyword detecting means 206 and the keyword inputted from the range deviation keyword detecting means 207 and the degree of change thereof based on the notified party information. The notification information is
For example, a keyword detected by the new keyword detecting means 206 has a format composed of a title of "new keyword", a total period, and a list of keywords, and a keyword detected by the range deviation keyword detecting means 207 is , A range deviation keyword, a total period, a keyword and a list of degrees of change may be included. If the notification destination information is the email address of the notified person, the notification information may be transmitted by email. Alternatively, a home page having notification information may be created and an e-mail with a hyperlink to the home page may be sent. However, you may mail the printed information with the notification information.

[Second Embodiment] In the first embodiment, the keyword input means 201 is supposed to input a keyword from the WWW server 102. However, as shown in FIG. 4, the keyword input means 201 is an Internet user who has a monitor contract. Keyboards 401-1, 401-2 ,. ． ． ,
You may receive the character string input into the keyboard from 401-n via the internet 402. The character string input from the keyboard is once written in the ring buffer provided in the main memory of the computer, and then B
It is read by IOS and handed over to the operating system and application program, but it intercepts the character code read from the ring buffer with the read pointer of the ring buffer as a clue,
It suffices to provide a program for transmitting the read character code by a protocol on TCP / IP. Alternatively, it can be realized by applying the telnet technology.

Further, the keyword input means 201 is connected to the morpheme analysis means 403 to extract the keyword from the character string input on the keyboard.

When using this method at a company or school, a LAN is used instead of the Internet 402.

[Third Embodiment] In the second embodiment, the character code input on the keyboard is input. However, in the case of Japanese or the like, morphological analysis cannot be performed only by the character code. Therefore, the second embodiment is practical when dealing with English, but not practical when dealing with Japanese. Therefore, in the third embodiment, as shown in FIG.
Front-end processors 403-1 and 4 for Japanese input
03-2 ,. ． ． , 403-n are input by the keyword input means 201 via the Internet 402. This can also be realized by applying the telnet technology.

[Fourth Embodiment] In the fourth embodiment, the keyword input means 201 inputs a keyword contained in a file recorded in the file server 502.

As shown in FIG. 6, the client 501-
1, 501-2 ,. ． ． , 501-3 and the file server 502 are connected by a network 503 to form a client / server system. Each client writes the file created by the client to the file server 502. The word extraction unit 504 inputs files sequentially written in the file server 502 from the file server 502 via the route 503, extracts keywords from the input files by morphological analysis, and outputs the extracted keywords to the keyword input unit 201. To do.

[0042]

As described above, according to the present invention,
Since the notified person can be notified of the newly appearing keyword, the notified person can grasp the signs of the trend from an early stage.

Further, according to the present invention, since the notified person can be notified of the keyword whose degree of change deviates from the predetermined range, the notified person can grasp the change in fashion from an early stage.

Further, according to the present invention, when searching for a keyword whose degree of change deviates from a predetermined range, the search target can be narrowed down to only the keyword selected by the notified person, so that useless content is notified. It is possible to prevent the person from being notified.

Further, since the notified person can know the newly appearing keyword and the keyword whose degree of change deviates from the predetermined range, he or she can predict the growth curve of the appearance frequency of the keyword, and accordingly Growth curves can also be predicted, and accurate future product, service, and social forecasts can be made.
