The present invention relates to an information providing system and method for searching and extracting information and advertisements of various news, papers, data files, etc. provided to the Internet, and providing the extracted information to Internet users according to their interests. In particular, it allows internet users to register keywords corresponding to their interests, and according to the registered keywords, news, papers, data files, etc., on the Internet, according to the registered keywords, After extracting the relevant advertisements and processing them together, we present the information providing system using the keyword and the information providing method using the keyword provided to the internet user by using e-mail, newsletter, real-time transmission method or text service. .

The Internet is an indispensable tool for modern people and is recognized as a means of providing infinite information. However, the Internet has many limitations in finding time, and it is not easy to search for specific information that is not well known. there was.

In addition, Internet e-mail is used as a channel to receive useful information, but recently, spam mails such as unsolicited advertising or pornography are randomly provided without the recipient's consent, rather than useful information. In particular, lewd mails are provided to children and adolescents as they are, causing serious harm to emotional development.

Therefore, Internet users want to be able to select the information they want and easily receive the information such as news, papers, data files, and advertisements in various ways. In order to provide selective information, the user provides information desired by means such as an email or a real-time pop-up window.

For example, Internet information providers that provide newspapers, weekly or monthly magazines offline, and provide news and articles online for a fee or free based on them, select membership fields and interests by category when registering. And a means of interest selection to make it possible. Therefore, when an Internet user requests to join the site as a member, inputs personal information, selects an interest using the interest selection means, and completes membership registration. The e-mail address included in the member's input personal information is transmitted.

However, as described above, the information providing method, even if the category of interest selected by the member, such as politics, economy, finance, sports, travel / leisure, music, computer, etc., has a wide range of interests, More news will be provided. In particular, since the operator transmits information mainly handled by the company, the range of information provided is very limited, making it difficult for members to obtain the desired information.

In addition, the companies that provide the information for free as mentioned above are added to the e-mail in order to make money, but these ads are randomly irrespective of the category of interests, so they do not cause interest to the members, Therefore, it is difficult to expect a large advertising effect because it is not easy to delete or view ads that are not related to such interests, and thus it is difficult to expect high advertising revenue.

In addition, in the conventional information provider, a method of allowing Internet users to select a category of interest in the above-described manner and providing classified information of the information provider corresponding to the selected category regularly or irregularly through e-mail. Is also used.

However, since the information provided as described above is category-specific information arbitrarily classified by the information provider, the range of information provided is wide and far from the information desired by the members, before the members read the information received by mail. Most of the cases were deleted. In addition, there is a problem in that there is a limit to provide the information desired by the members because often only processed data obtained from the information provider by category.

In addition, if you click on the information of interest after opening the information mail provided as described above, the information is directly connected to the site of the searched company, so it is possible to generate revenue only through the attached advertisement when sending the email without passing through the information providing sites. In addition, there was a problem that the width of advertising revenue becomes smaller.

In addition, there is a method of providing news in real time through a real-time execution program such as Active X, which is currently provided a lot, but this is mostly provided by a company such as a newspaper company to provide information without a subscription. Simply downloads and installs the executable program on the company's site, receives the information sent from the company on the Internet, and displays updated information directly on the user's monitor. However, the above-mentioned real-time information providing method has a problem that it is difficult to obtain information such as necessary news since it is not possible to select a field of interest and thus must receive information provided by the company without manual addition or subtraction.

As described above, since the information provided by the conventional Internet operators mostly includes only the information related to their interests in the interests selected by the members, the Internet users who actually request a variety of information about the specific interests are substantially different. It was very difficult to live up to expectations.

In order to solve the above problems, the present invention registers a specific interest of a user's interest with a keyword and an information source to be searched through the keyword, and searches for and provides information corresponding to the registered keyword. The purpose is to ensure that only information is provided.                         

In addition, by searching for an advertisement corresponding to the keyword registered by the user and simultaneously providing information using the keyword corresponding to the searched keyword using an e-mail or a real-time program, the user maximizes the advertisement effect by viewing the advertisement about the interest once more. To make sure that you can earn high advertising revenue.

In addition, when the information is clicked to view the information such as the e-mail, the newsletter or the news provided through the real-time program in detail, the information server can be accessed through the web server of the information provider. Another goal is for the company to display the desired advertisement on one side of the site of the information holder.

In addition, by using a text service or a swap of the mobile communication means as well as Internet e-mail, newsletters or real-time programs as the information providing means to provide the information obtained through the keywords entered by the user using a variety of information communication means The purpose.

In order to achieve the above object, the present invention receives a request from the terminals of the Internet user for input of necessary information and keywords and information sources for searching the keywords, and searches for information on the Internet to search for information corresponding to the keywords. And an information providing system using the keyword, wherein the extracted information is transmitted to the e-mail address of the user who registered the keyword.

In addition, the information providing system using the keyword further comprises an advertising module for receiving an advertisement from the advertisers using the Internet, and extracts and provides an advertisement associated with the registered keyword among the received advertising. do.
