Internet Information search technology-symmetric search

Internet

information search is an irresistible user requirement in the field of Internet Information sharing. The breakthrough in search technology is equally important for the Internet itself and for Internet users. The development of search technology The basic method used by the first generation search engine is to create the website name, the text summary of the website content by the Web producer, and add it to the search engine database. The search engine matches, sorts, and displays the information typed by the user. The biggest disadvantage of this approach is that it is not possible to search the content of the Web page for Full-text, and it must be typed by the Web page creator for the search. The basic method of the second-generation search engine is to use a program to retrieve data on the network and automatically store the results in the database. The search engine matches, sorts, and displays the information typed by the user. It has the advantage of not requiring a site producer to type in a separate search for information, and theoretically, to add all pages of any Web site to its repository. And its biggest drawback is that the results of the search is too much, in fact, users are still difficult to find the real data, and the database capacity is expanding trend. How to accurately find the right data from a large database has been recognized as the competitive point of the next generation search technology. The current emerging technologies are: Smart Search The basic method is to improve the availability of search results by automatically learning the relevance of search content. But the problem is the face of massive and complex information publishing content, if there is no one in the publisher and the search end of the sharing of information matching module, only rely on intelligent search can not fundamentally improve the accuracy of information search, so that users really need the information must be displayed in the first two or three pages of search results. Vertical search is the search technology in the fields of image information, music information and so on. Peer-to-peer Search is one of the search technologies in the future, its basic method is that users share all the user's hard disk files, directories and even the entire hard drive. Search does not need to go through a Web server or be limited by the format of information documents and host devices to reach the depth of the traditional directory search engine (which can only search for 20%~30% network resources) (theoretically including all the open information resources on the network). The first problem of Peer-to-peer search is to solve the problem of accuracy of information matching, and the imbalance of personal information and public information that may bring. The information stored in the computer is usually personal information, and the Web site information in the server is the mainstream of public information. In the future, another kind of search technology is "information Service Network", its main characteristic is that it not only includes computer and webpage information search, but also includes various information resources, such as database, software and information processing function integration. The entire network, like a huge computer, provides an integrated service to every user. Its main problems are similar to the development of E-commerce, that is, the integration of all information services and related technologies requires the establishment of a unified standard, and the establishment and promotion of such standards is not 35 years of work, and it is difficult to imagine that only one standard appears. Also, from a business standpoint, the performance price ratio of services is also a worrying issue. Symmetric search Technology 1. Principle of Symmetric search In essence, "Publish information" and "Retrieval Information" is a kind of symmetrical information communication demand. Therefore, we can build "publish information" and "Retrieve information" symmetric database and symmetric search technology. The blind spot of the existing search technology is that it wastes a lot of labor and huge information resources that the information retrieval party pays in the information retrieval. 2. The realization of symmetric search (1) The establishment of "Symmetric Information Digest General template", which includes the release/Get selection, data type, content summary, publisher domain name, email address, release time; (2) The establishment of a "Symmetric information digest" database; (3) Information dissemination and information acquisition users in the "Symmetric Information Digest General template" on the input of information; (4) Search engine according to user requirements, the "Symmetric Information Digest database" for multiple matches; (5) ranking according to the matching degree of symmetrical information; (6) Two-way automatic push of matching result according to the address provided by both sides of symmetrical information; (7) By the user to select whether to link to the relevant site details. Information classification, Information Digest, basic user information is the basic content of symmetrical information matching, only reasonable integration of these three kinds of information elements, can design a "symmetrical information man-machine interaction template" and high quality "symmetric information database" which all users are convenient and willing to use. 3. The superiority of symmetric search technology The symmetry search technology makes the accuracy of symmetry information matching unprecedented increase; At the same time, a one-time search can enjoy different times of search results, so that user search operation is simple; In addition, the Digest database does not expand indefinitely compared to Full-text databases; It is also important that the Publisher provide summary information and retention time by itself. Plus the summary database space occupancy charges, which is actually the most effective means of controlling spam, so that the spam information greatly reduced. If you can significantly improve the targeted information dissemination, and the operation is very convenient "Symmetric Information Digest General template", has done a Web page and updated the content of the Web page users, but also care to fill in the summary? 4. Commercial application of Symmetric search technology (1) Symmetric search Technology example--"symmetrical advertisement" There are some shortcomings in the existing advertising forms of the Internet, such as the high cost of large broadcast advertising, the majority of small and medium-sized enterprises are difficult to bear; classified ads have no mandatory information release, most manufacturers and users are not interested in; the recessive advertisement of the search engine decides the rank order of the search result according to the The mail advertisement only relies on the user basic registration information and the existing business information to publish the advertisement, the user's pertinence is not strong, most is regarded as the spam advertisement by the user. The comparative advantage of symmetrical advertisement has the following two aspects: on the one hand, for advertising companies, the unprecedented increase in advertising issued by the targeted, the advertising price of any small enterprises can withstand; At the same time, the enterprise one-time release information, can be automatically pushed to the relevant customers, the enterprise can get the potential users accurate information. On the other hand, for advertisers, it really achieves user demand first, according to the specific needs of the user to push the advertising information, according to the advertising information and user demand information of the objective matching degree of advertising ranking; the user once "retrieves" the information, may obtain the related information the automatic push service repeatedly; eliminates spam, Ease the user burden. (2) The business operation mode of symmetrical search Symmetrical search chain operation Each kind of portal website can share and provide local customer settlement service through "Symmetric information database", share "symmetric information" resources, and realize the maximization of service coverage. Symmetrical advertising browsing points for free email E-mail is the most Internet users can not give up the steel demand. Using symmetrical advertising to browse points for free mailbox is not only a kind of compulsory advertising method acceptable to the user, but also a kind of charging way of the mailbox disguised by the user. Because the online symmetrical advertising has a difficult to replace the performance price ratio, so it can be expected that symmetrical advertising as a low-cost general-purpose point-to-point advertising, will become the preferred advertising mode for most small and medium-sized enterprises, so that the Internet advertising industry to bring brilliant tomorrow! 5. The extension of symmetric search technology If we can provide "symmetric information" high-quality Multilingual conversion technology, you can achieve the language-free "symmetric information" universal search service. But "the text semantics human-Computer Interaction Unified Coding Technology", "the whole domain digital knowledge information localization Technology" has also made the decisive breakthrough in solves the multilingual translation quality question. Therefore, it is expected that in one year, the single language "Symmetric Information Retrieval" service will enter the universal stage, within two years, users can enjoy a reliable and practical multilingual universal "symmetric information" retrieval services.
