Description

  The present invention is an article such as news published on a computer network (originally "article" is mainly a sentence that faithfully describes the fact, but here it does not matter whether the content is fact or not. In particular, the present invention relates to an information distribution apparatus, an information distribution system, an information distribution program, and an information distribution method for collecting and distributing articles that match a user's purpose.

  Many articles are published every day on the Internet using the World Wide Web (WWW) system. The amount of articles distributed on the Internet is enormous and includes many articles other than articles intended by each user. So, for example, you can search for articles that match the user's purpose by entering keywords on the homepages of the media companies or the homepages of major portal sites such as Yahoo! JAPAN and Goo. I have to.

  In recent years, there are many requests for receiving only articles that meet a specific purpose of the user from among these many articles. For example, in Patent Document 1, a user's e-mail address and a search word for news information are registered in a computer, and news information is selected and collected from news of the world based on the search word. A technique is described in which these news information is distributed at any time within a predetermined time and distributed by e-mail.

  In Patent Literature 1, news information targets are TV news, information from news agencies, newspaper articles, magazine information, company announcements, securities trading market information, etc., and news information is extracted in advance from these information, It is described that the data is converted into computer data. Such news information can be easily selected and distributed based on a search word or the like if it is pre-formatted manually for distribution.

JP 2001-331520 A

  However, it is not easy to automatically collect and distribute articles that match the user's purpose from articles published on a web page on the existing Internet. Web pages for publishing news articles on the Internet are written using a markup language called Hyper Text Markup Language (HTML). The markup language is a description language in which a part of a document is surrounded by a special character string called “tag” to describe the structure of the document and modification information in the document.

  If the web page consists of only the character string indicating the content of the article, automatically collect and distribute the character string of the article that matches the purpose of the user from the character string indicating the content of this article. It is easy to format for distribution. However, as described above, a web page that actually publishes an article includes not only a character string indicating the content of the article but also a character string indicating a tag for describing the structure of the sentence. For this reason, a string that indicates a tag is mixed in a series of character strings that indicate the text of an article, and it is difficult to automatically collect and distribute articles that match the user's purpose. is there.

  Therefore, in the present invention, it is possible to automatically collect and distribute articles that meet the user's purpose from articles such as news published on a web page on a computer network such as the Internet or an intranet. An object is to provide an information distribution apparatus, an information distribution system, an information distribution program, and an information distribution method.

  The information distribution apparatus according to the present invention includes URL storage means for storing a URL of a web page including an article published on a computer network (URL; Uniform Resource Locator), a keyword for each user, User information storage means for storing the e-mail address of the delivery destination, data collection means for collecting data of web pages including articles based on the URL stored in the URL storage means, and data collected by the data collection means The data storage means to be stored, the part of the data stored in the data storage means that includes the keyword stored in the user information storage means except for the character string indicating the tag, and the characters for a predetermined number of characters before and after this part Extracted by data extraction means for extracting column data and data extraction means Data combining means for combining character string data into text, mail creating means for creating an e-mail containing text data documented by the data combining means, and user information storage means for creating the e-mail by the mail creating means And e-mail transmitting means for transmitting to an e-mail address stored as a delivery destination.

  The information distribution method of the present invention includes a data collection step for collecting data of a web page including articles published on a computer network, a data accumulation step for accumulating data collected by the data collection step, and a data accumulation A data extraction step for extracting a character string data corresponding to a predetermined number of characters before and after the portion including the keyword for each user except the character string indicating the tag in the data accumulated in the step, and the data extraction step A data merging step that combines the extracted character string data into a sentence, a mail creation step that creates an e-mail containing sentence data transcribed by the data merging step, and an e-mail created by the mail creation step for each user Send to the email address of the destination And a mail transmitting step.

  According to the information distribution apparatus and the information distribution method of the present invention, articles published on a web page on a computer network are collected, and a character string indicating a tag is excluded from data of the collected web page. Character string data corresponding to a predetermined number of characters is extracted from the part including the keyword and before and after this part, and is converted into a sentence, which is sent as an e-mail containing the sentence data to the e-mail address of the distribution destination for each user. Since the text data included in this e-mail is composed of a character string of a predetermined number of characters before and after the tag portion with the keyword at the center, the user who has received this e-mail It becomes possible to grasp the content of the article by the character string. In addition, if a character string of a predetermined number of characters before and after including a character string indicating a tag is extracted and converted into a sentence, the character string of the article part is reduced by the character string indicating the tag, so the content of the article is grasped I can't do that.

  Here, the character string indicating the tag is, for example, a web described in HTML which is one of markup languages which is a standard created by W3C (WWW Consortium). This is a character string that is described to clearly indicate the position of an element and store attributes in a page. The tag includes a start tag, an end tag, and an empty element tag. Each tag is surrounded by a greater-than symbol “<” and a less-than symbol “>” in HTML. That is, the character string indicating the tag indicates a character string in a portion surrounded by the greater-than symbol “<” and the less-than symbol “>”.

  In addition to the character string indicating the tag, since the character string indicating the blank is not necessary for grasping the content of the article, the data extracting means adds the character string indicating the blank in addition to the character string indicating the tag. It is desirable to exclude. As a result, the text data included in the e-mail is composed of the character string of the article part for a predetermined number of characters before and after the tag part and blank character string, with the keyword as the center, so that the user who received this e-mail Makes it possible to grasp the content of an article by a character string of a predetermined number of characters before and after a keyword excluding a character string indicating a blank unnecessary for grasping the content of the article.

  Further, the mail creation means obtains the link destination URL from the link tag formed by enclosing the character string including the keyword extracted by the data extraction means among the data stored in the data storage means with the start tag and the end tag. And should be included in the email. Thus, as described above, the text data including the keyword to be included and transmitted in the e-mail includes the URL of the link destination of the web page related to this keyword. In addition to being able to grasp the content of the article, it is possible to browse the web page that is the source of the article by the URL of the link destination. The link tag enclosed by the start tag and the end tag is a tag for setting a link. For example, in HTML, the start tag “<a href="(URL of link destination)”> "And an end tag" </a> ".

  The information distribution program according to the present invention uses a URL storage means for storing a URL of a web page including an article published on a computer network, and a keyword and a distribution destination e-mail address for each user. Person information storage means, data collection means for collecting web page data including articles based on the URL stored in the URL storage means, data storage means for storing data collected by the data collection means, and data storage means A data extraction means for extracting a character string data corresponding to a predetermined number of characters before and after the portion including the keyword stored in the user information storage means except the character string indicating the tag in the data stored in Data combining means for combining text data extracted by the data extracting means into a sentence; Mail creating means for creating an e-mail containing sentence data sentenced by the data combining means, and mail for sending the e-mail created by the mail creating means to an e-mail address stored as a delivery destination in the user information storage means It is for functioning as a transmission means. According to the computer which executed this program, the same operation and effect as the above-mentioned information distribution device of the present invention can be produced.

(1) According to the present invention, an article published by a web page on a computer network is collected, and a keyword intended by a user is removed from the collected web page data except for a character string indicating a tag. The character string data for the specified number of characters before and after this part is extracted, converted into text, and automatically sent to the destination email address for each user as an email containing the text data Is possible. The text data included in the e-mail is composed of a character string of an article part of a predetermined number of characters before and after the tag part centered on the keyword intended by the user. The contents of the article can be grasped by a character string of a predetermined number of characters before and after this.

(2) By a configuration in which data extraction is performed by removing a character string indicating a blank in addition to a character string indicating a tag, a predetermined number of characters before and after a keyword excluding a character string indicating a blank unnecessary to grasp the content of an article It becomes possible to grasp the content of the article by the character string.

(3) The URL of the link destination is acquired from the link tag formed by enclosing the character string including the keyword extracted by data extraction in the data accumulated by the data accumulation by the start tag and the end tag.

To extract.

  Here, in this embodiment, 30 characters before and after the keyword portion are extracted as the predetermined number of characters. Extracting with fewer than 30 characters makes it difficult to understand the content of the sentence, and conversely extracting with more than 30 characters makes the keyword inconspicuous because the sentence is long. The predetermined number of characters may be configured to extract characters having different numbers before and after the keyword portion. The number of characters to be extracted can be arbitrarily set by the administrator of the news distribution apparatus 1 and the users such as the user terminals 3a to 3c. Further, the data extraction means 14 extracts character string data for a predetermined number of characters excluding a character string indicating a tag and a character string indicating a blank, as well as other character strings such as other symbols unrelated to the content of the article. It is also possible.

  The data combination means 15 combines the character string data extracted by the data extraction means 14 into a sentence. In the present embodiment, the data combining unit 15 converts the extracted character string data into a sentence by simply combining the extracted character string data. However, the data combining unit 15 converts the extracted character string data into a more easily readable sentence data by performing other processes. A configuration is also possible.

  The mail creating unit 16 creates an electronic mail including the text data converted into text by the data combining unit 15. FIG. 4 shows an example of the body of an electronic mail created by the mail creating means 16. Further, the mail creating means 16 starts the character string including the keyword extracted by the data extracting means 14 among the data accumulated in the data accumulating means 13 with the start tag “<a href="......”>”. The link destination URL 21 is acquired from the link tag enclosed by the end tag “</a>” and arranged adjacent to each sentence data 22 in the e-mail body.

  Further, the mail creating means 16 may be configured to decorate each keyword of the document data in order to make the keyword easy to see. For example, in the case of an e-mail in a normal text format, the decoration is given a symbol or the like in the keyword part, and in the case of an HTML e-mail, the keyword part is colored or underlined.

The data is stored (cached) in the data storage unit 13. At this time, if the accumulated content is the same as the previously accumulated content, the following processing is not performed for the web page.

(Step S <b> 102) In the news distribution apparatus 1, the data extraction unit 14 searches the keyword stored for each user stored in the user information storage unit 11 from the data stored in the data storage unit 13. At this time, the data extraction unit 14 searches for a keyword from the data stored in the data storage unit 13 by removing a character string indicating a tag and a character string indicating a blank.

(Step S103) When there is a corresponding keyword, the news distribution apparatus 1 extracts the keyword by the data extraction means 14 and extracts character string data of 30 characters before and after the keyword. At this time, the data extraction unit 14 extracts character string data of 30 characters before and after the keyword, excluding the character string indicating the tag and the character string indicating the blank. In addition, when there is no corresponding keyword in step S102, the news distribution apparatus 1 does not perform the following process for the keyword.

(Step S104) The news distribution apparatus 1 combines the extracted keyword and character string data of 30 characters before and after the data combining means 15 into a sentence. If the sentence data documented here is the same as the previous one, the following processing is not performed on the sentence data.

(Step S105) The news distribution apparatus 1 creates an e-mail including sentenced sentence data 22 by the mail creating means 16 (see FIG. 4). At this time, the mail creation means 16 adds information related to the search target keyword to the electronic mail. In addition, the mail creation means 16 includes links associated with each sentence data 22 from link tags formed by enclosing character strings including keywords extracted by the data extraction means 14 in the data accumulated in the data accumulation means 13. The previous URL 21 is acquired and arranged adjacent to each text data.

(Step S <b> 106) The news distribution apparatus 1 transmits the created electronic mail to the electronic mail address of each user stored as a distribution destination in the user information storage means 11 by the mail transmission means 17.
