Google ranking third generation of search engine technology and P2P
Second-generation search engine google ranking Although the first generation in the search speed, in view of the expansion of multilingual information, such as an improvement in a natural language query language has also done some exploration. However, with the strong development of the Internet, online huge number of people to obtain the necessary information and the conflict between the information capabilities are becoming increasingly prominent. In the latter half of 2001, IDC released a report that was widely publicized early for the "use easy-to-use, rich search results," the google search engine ranking information technology is being replaced by a more centralized LAN, as the majority of the performance of the system and search user expectations to be too great, such as the volume of data and high-speed growth of video, audio and other multimedia information retrieval, and still is unable to break through problems.
The general public can only search engine can be found in HTML format, the main reason is that sort of automatic search engine spiders software Spiders procedures, can only accept this kind of format web site. This means that the internal LAN in the enterprise, did not use any of the information in HTML format will not be available outside the search engine. That is why like PPT, Word, PDF, e-mail and other documents, as well as ERP, CRM applications such as database information will be long-term "sinking" in the information in the seabed.
How to solve these problems has become the third generation of search engines explore direction. No longer a good search engine database only by virtue of the size and update frequency, retrieval speed, multi-language support these basic characteristics to measure, with the continuous expansion of the database capacity, how huge database to find the right precision the information was generally acknowledged to be the next generation search technology and the competition points. For example, in a search engine for "tourism" the word, the return of information over 1 million, assuming a 3 seconds Show a web page, even if only 10 per cent of the Show's website, around the clock Read also requires 10 hours.
Fortunately google search engine ranking rapid development of technology, such as intelligence, personality characteristics of the new engine and the search engine compared to the past with great distinction. Intelligent Search can search through the content of automatic learning, to improve the accuracy of search results. However, there was not a feasible way to achieve truly intelligent, it is difficult to show the required information must first 23 search results.
Another popular attention is the search technology will be applied to the P2P technology in the Web search. By sharing all files on the drive, directory, and even the entire hard drive, users need not search through the Web server, file format information from the restrictions can be reached traditional directory search engine unparalleled depth (traditional engines can only reach 20% ~ 30% of the network resources). The United States a new search engine design company i5 Digital two years ago has been officially launched on the basis of the search, such as the concept of commercial search engine Pandango (www.pandango.com), but has yet to enter the mainstream search engine lineup fact, that P2P search is now only known as the technology of the future.
"P2P search this idea by the end of 1997 I was first heard in Infoseek, then Infoseek, has been raised and began to consider this google ranking search technology," Robin Li said, "all have a website of its own small search engine, we can communicate with each other, if this Chabudao engine, the engine can search through other, is one such concept. But so far, it is still practical application from the very far, mainly breach of key indicators in the speed issue. fact that many such small independent mutual links and the engine, the speed and centralized management compared to the search engine will certainly be a lot worse. "
Academic research and commercial applications between the Federation There is a certain distance, but that does not mean that the business community does not pay attention to the pursuit of technology, especially as Google has been in the field these tip of the pyramid companies. Google has an open database, containing more than 100 future needs of the implementation of projects by 50 Dr. promote computer science. June 2002, Google has set up a "laboratory" to demonstrate their Internet search of the latest research in the field of technology, and posted on the Internet (labs.Google.com) for public trial, extensive collection of user feedback. Has been demonstrated in laboratory projects, including keyboard access, voice retrieval, and so on.
Perhaps some people may think that these so-called pilot project seems to be no search engine technology will be conducted on the concept of the change, in fact, search engine technology in more than eight years, the time has been a gradual change is in the process of development. "A search engine is not to say that one aspect can be better liked by the public, we must do all aspects of theæ‰è¡Œ" Robin Li so that the "search now also can not completely meet the people's needs, because demand is too diverse, it is difficult one a meet. " This is the current mainstream search engines pay more attention to the details of efforts reasons.
Nevertheless, Pei-Chieh, including Google's search technology leader in the field believe that the ultimate search engine will be intelligent, to the world's understanding of all things. Pei-Chieh or Web services technology active participants, he is trying to use Web services technology to search, to resolve the cross-platform, multi-format information retrieval. And what we are seeing, mainstream search technology to focus on upgrading the quality of its search engine, to expand the scope of application, for example, support picture retrieval, PDA mobile handheld devices such as the retrieval of these will become the next generation of process technology will essential steps.
