Description

  The present invention relates to a Web page search program and a Web page search system that can search a Web page on the Internet without putting effort such as setting a search keyword. Specifically, the user searches for a search by automatically generating a search keyword by using a word included in a document of a Web page searched and browsed by the user in the past or information on the operation of the terminal device by the user. The present invention relates to a Web page search program and a Web page search system that do not require an operation for determining and inputting a keyword for use.

There are many search servers on the Internet that search web pages according to keywords or search formulas specified by the user and present the title of the corresponding web page to the user. However, in order to use such a search system, the user may need to determine a keyword or search expression that matches the purpose. However, it takes a lot of labor to determine a search keyword or search expression and enter it in a predetermined field. In order to reduce these efforts, a method for assisting keyword selection is considered. For example, in Japanese Patent Application Laid-Open No. 2007-323292, when a user transmits an e-mail to a search server, the server extracts a keyword from the e-mail and performs a search based on the keyword. A configuration is described in which a history database for storing keywords extracted from e-mails is provided for each user, and the history is reflected in a search for a Web page. The technology described in this publication generates a keyword for search based on an email sent by a user, and the user needs to create an email. Requires labor.
JP 2007-323292 A

When searching for a Web page, the user needs to select a search keyword for specifying the target Web page, input it from the terminal device, and send it to the search server. Such a search is suitable for searching a Web page that matches a specific purpose. However, in the form of using the Internet, in addition to the method of using with a certain purpose as described above, the form of browsing a Web page without having a specific purpose, such as reading a magazine during the waiting time of a hospital etc. There is. For such a usage mode, a strict search in which a user selects and inputs a specific search keyword is not necessary. However, if the search keyword is not used at all and the web page is accessed completely at random and presented to the user, the probability of the user accessing a page that does not wait for interest at all increases, and there is no use value for the user. It will be a thing.
The present invention requires the user to select and input a search keyword by extracting words that are expected to be of interest from the user's behavior, etc., and using those words as search keywords. It is intended to provide a program and a system that realize a simple search function that does not.

  The present invention has a configuration in which the terms for a keyword are collected by analyzing the contents of a Web page viewed by a user. The user does not need to create a search keyword, and only operates a simple search key set in a user device such as a portable terminal, and resembles a user's past behavior or an attribute preset by the user. It is possible to search for a web page having content and provide it to the user.

FIG. 1 is a functional block diagram of a first embodiment according to the present invention. The portable terminal 100 transmits a search keyword to the search server 120 via the communication network 115 and instructs the search for the Web page.
[Input unit 101]
Input unit 101 is a part that accepts input from the user, and consists of numeric keys, cursor keys, etc. In addition to alphabet input and Japanese input by kana-kanji conversion function, it is possible to select instructions of data items displayed by cursor keys It is. Moreover, the function of a normal information terminal, such as executing an application program such as a game that the mobile terminal has, is used. The server 120 requested to search from the mobile terminal 100 returns a predetermined number of Web page titles, outlines, and the like that match the request to the mobile terminal 100 and displays them on the display unit of the mobile terminal 100. When the user designates the title of the web page that the user wants to browse using the cursor key or the numeric keypad, the mobile terminal 100 accesses the web server in the Internet, acquires the designated web page, and displays it. The input unit 101 passes the web page title and the content of the web page designated by the user to the action acquisition unit 102. In addition, the input unit 101 passes information such as information about a game played by the user and an email to the action acquisition unit 102.

[Behavior acquisition unit 102]
The behavior acquisition unit 102 acquires information regarding the behavior performed by the user on the mobile terminal. For example, the name of the game played by the user, the information of the created or received mail is collected. In addition, character information such as a function description or a service description that is the content of the Web page viewed by the user is received from the input unit 101. The acquired information is transferred to the behavior analysis unit 104, and information such as the word used for the keyword and the frequency is extracted.
[Behavior analysis unit 104]
The behavior analysis unit 104 analyzes the data collected by the behavior acquisition unit 102, extracts words, appearance frequencies, and the like and records them in the analysis behavior storage unit 105. The analysis procedure is as follows.
(1) Word extraction The information acquired by the action acquisition unit 102 is subjected to morphological analysis with reference to the word dictionary, grammatical items, and the like stored in the analysis word dictionary 103, and the contained words are extracted.
(2) Calculation of Appearance Ratio of Extracted Words Calculate the total number of words extracted by morphological analysis and the appearance ratio of each word. The appearance ratio is obtained by dividing the number of appearances of each word by the total number of extracted words.
(3) Data update in the analysis action storage unit The ratio obtained by the above calculation and the information of the acquired date and time are added to each word and stored in the analysis action storage unit 105. If the same word already exists, the ratio value obtained this time is added to the ratio value assigned to the word. Also, the date and time given are updated to the current date and time. Note that words that have passed a predetermined number of days from the date and time of the last appearance are deleted. The number of days until deletion can be arbitrarily set by the user.
Ranks are assigned to words stored in the analysis behavior storage unit 105. Ranking is determined by the rate of appearance and the old and new update date. Which is prioritized can be arbitrarily set, but for example, the update date is given priority by default.

[Analysis behavior storage unit 105]
FIG. 2 shows an example of data stored in the analysis behavior storage unit 105. The current word table (a) is changed by the words “meal”, “fashion” and “scenery” extracted by the behavior analysis unit 104, and a new one is created. A simple word table (b).
The table includes a word item 201, an item 202 for storing the rate of occurrence of a keyword, and an item 203 for storing the last date and time when the word appeared. In this embodiment, the user can arbitrarily set the period for holding the word. Fig. 2 shows the point in time when word data is deleted, when the word appears last on a web page, etc., and 30 days have passed since the data was updated, that is, the data was not updated for 30 days. Suppose that the time is set, and that the word “Soba” 211 has already appeared for more than 30 days.
When the behavior analysis unit 104 instructs the analysis behavior storage unit 105 to update the word table, the control unit of the analysis behavior storage unit 105 inspects the item 203 of the last date and time of the table, and there is a word with a date 30 days ago. Check whether or not to do so, and delete words that meet the conditions. In the item 203 of the last appearance date and time of the word “soba” 211 in FIG. 2A, the date on which “soba” last appeared is January 2, 2008, and more than 30 days have already passed. Therefore, the control unit of the analysis behavior storage unit 105 deletes the word “soba”.

The control unit of the analysis behavior storage unit 105 checks whether or not the word that the behavior analysis unit 104 has instructed to update is already stored in the word table. When the same word is stored, a value obtained by adding the current ratio value calculated by the behavior analysis unit 104 to the value held in the word appearance ratio item 202 is set as the appearance ratio. Also, the last appearance date / time item 203 is updated with the current date / time read from the clock mechanism of the apparatus.
The words “meal” 213 and “fashion” (not appearing in FIG. 2A) already exist in the word table of FIG. Therefore, the control unit of the analysis behavior storage unit 105 corrects the items 202 of “appearance ratio” of “meal” 213 and “fashion” and the item 203 of the last appearance date and time so that the words “meal” 214 and “ “Fashion” 215.
The word “scenery” is not recorded in the table of FIG. Therefore, the control unit of the analysis behavior storage unit 105 generates the term 217 of the word “scenery” and records the appearance ratio value received from the behavior analysis unit 104 and the current date and time.
The control unit of the analysis behavior storage unit 105 sorts the stored words in descending order of appearance ratio. If the sum of the appearance ratios is the same, the one with the newest update date is ranked higher.

[Search content creation unit 106]
When the user operates the key of the mobile terminal 100 to instruct a simple search according to the present invention, the search content creation unit 106 requests the search server 120 to perform a search from the word table stored in the analysis behavior storage unit 105. Extract keywords. Although the selection method can be determined arbitrarily, the determination method is illustrated below.
1. The search content creation unit 106 obtains X words having the highest appearance ratio (number X can be changed) from the words stored in the analysis action storage unit 105.2. Y words are randomly added from the lower words excluding the above X words.
Y is an integer rounded down to the upper number X * (random number between 0 and 1). (Y is 0 <= Y <= X-1 and if Y> 0, Y words are selected and added. If Y = 0, no words are added from the bottom. Same word at the top and bottom. In the case of, it is not necessary to give the same lower word)

For example, the words are music, fashion, ..., scenery, ... meals, the total number of extracted words is 100, and the number of occurrences and the ratio of each word are calculated.
Word: Number of occurrences, percentage Music: 43, 0.43
Fashion: 32, 0.32
Meals: 20, 0.20
……………
Views: 7, 0.07

[Get upper word]
When the number of upper keyword acquisitions X is 3, the top three appearance ratio values are acquired. In the above example, “meal”, “fashion”, and “Italy” are selected.
[Lower word acquisition judgment / acquisition]
The number Y of low-order keywords acquired is calculated by Y = X * (random number from 0 to 1). When the random number calculated by the arithmetic unit of the portable device is 0.31, the above formula is 3 * 0.35 = 1.05, and the decimal part is rounded down to Y = 1. Therefore, one lower word is acquired. Acquisition is done randomly. For example, if “scenery” is selected, “meal, fashion, Italy, landscape” is determined as a search keyword. However, it is possible to change such as (1) X is set to 0 and only the lower Y is set, (2) Y is set to a fixed value, and (3) Y is set to X-1 or more. is there.
It is also possible to have a configuration in which X and Y can be individually specified without having X and Y interlock. In this configuration, Y can be set even if X is 0, and Y need not be less than X-1. In addition, a configuration in which X and Y are not linked and both values are not fixed values is also possible. This configuration is a method in which X and Y are upper limit X from the upper order and upper limit Y from the lower order.For example, when X = 10 and Y = 2, X is multiplied by a random number from 0 to 1, and the upper number Xr is Assume that 0 <= Xr <= X (= 10) and the lower number Yr is 0 <= Yr <= Y (= 2). As a result, combinations of (X = 0, Y = 2), (X = 5, Y = 1), etc. are possible.
