IT History: Search Engine History [2004-11-5] Pregnant Birth - Search Engine Development History 1990, no one can search for the Internet. The ancestors of all search engines are Archie (Archie FAQ) invented by Montreal McGill University Students Alan Emtage, Peter Deutsch, Bill Wheeland in 1990. WORLD WIDE Web has not yet appeared. Archie is the first program for an anonymous FTP website file on the Internet, but it is not a real search engine. Archie is a list of searchable FTP file names, and users must enter exact file name search, and Archie will tell users which FTP address can download this file. Because Archie is deeply popular, Nevada System Computing Services developed a Gopher (Veronica FAQ) in 1993 in 1993. Jughead is later another gopher search tool. Due to the Robot program that is specifically used to retrieve information, it climbed between the spider (Spider), and therefore, the Robot program of the search engine is called the Spider FAQ program. The world's first Spider program is Mit Matthew Gray World Wide Web Wanderer for tracking the development of the Internet. Just starting it only to count the number of servers on the Internet, and later developed to capture the URL (URL). Compared with Wanderer, October 1993 Martijn Koster created AliWeb (Martijn Koster Annouces the Availability Of Aliweb), which is equivalent to Archie's HTTP version. AliWeb does not use the network search Robot, if the account authority wants your own web page to be included by AliWeb, you need to submit your own web page profile information, similar to that of you are familiar with Yahoo. At the end of 1993, some search engines based on this principle have emerged, of which three of them are: Scotland's JumpStation, Colorado University Oliver McBryan's The World Wide Web Worm (First Mention of Mcbryan's World Wide Web Worm), NASA Repository-based Software Engineering (RBSE) Spider. In February 1993, the idea of 6 Stanford (Stanford) college students was to analyze words related to more efficient retrieves on large amounts of information on the Internet. This is Excite. Later, I was known for the concept search. In May 2002, Excite acquired by InfoSpace stopped her search engine, modifying the sexy search engine DOGPILE in January 1994, the first one can search for also brutal classification directories Einet Galaxy (Tradewave Galaxy) Online. In addition to the website search, it also supports Gopher and Telnet search. In April 1994, two doctoral students, American Chinese Jerry Yang (Yang Zhiyuan) and David Filo found Yahoo. As the number of visits and the number of inclusive links, the Yahoo directory begins to support simple database search. Because Yahoo! data is manually entered, it cannot be truly being collected as a search engine, in fact, just a searchable directory.
Search efficiency is significantly improved. (Yahoo later using Altavista, Inktomi, Google offers search engine services) At the beginning of 1994, the University of Washington CS student, Brian Pinkerton, started his small project WebCrawler (Brian Pinkerton Announces the Availability Of Webcrawler). On April 20, 1994, WebCrawler included only content from 6,000 servers. WebCrawler is the first full-text search engine that supports all text on the Internet. Before it, users can only search by URL and summary, and some generally from artificial reviews or procedures automatically take the top 100 words of the text. (Later, WebCrawler was successfully acquired by AOL and EXCite, and now the same as Excite is used to switch the dogpile of Yuan Search Engine Dogpile. "Carnegie Mellon University Center for Machine Translation Announces Lycos is another important progress in the history engine history. Michael Mauldin, Carnegie Mellon University, entered John Leavitt's Spider program to its index, created Lycos. On July 20, 1994, LYCOS was officially released in the amount of 54,000. In addition to the relevance sorting, LYCOS also provides prefix matching and characters similar limits, LYCOS first uses webpage automatic summary in search results, and the greatest advantage is to compete over other search engines data: 1994 8 Month - 394,000 Documents; January 1995 - 1.5 Million Documents; November 1996 - Over 60 Million Documents. (Note: In April 1999, Lycos stopped his Spider, changed from FAST to search engine service) Infoseek (Steve Kirsch Announces Free Demos Of The Infoseek Search Engine) is another important search engine, although the company claims to Jan 2004 It has been created, but it is until the end of its search engine meets the public. At first, INFOSEEK was just an inconspicuous search engine. It followed the concept of Yahoo! and Lycos, and there was no unique innovation. However, its development history and later praised proved that the first first step is not always important. Infosek-friendly user interface, a large number of additional services (Such as ups tracking, news, a directory, and the like) makes it rolling. The strategic agreement with Netscape in December 1995 made it a strong search engine: When the user clicks on the search button on the Netscape browser, the Infoseek's search service is popped up, and the service is previously provided by Yahoo!. (Note: Infoseek later, in February 2001, Infoseek stopped his search engine, starting to use Overture search results) in 1995, a new search engine formatic - Yuan Search Engine ( A Meta Search Engine Roundup.
Users only need to submit a search request, submitted to multiple pre-selected independent search engines after the transformation process is converted, and the results of all query returned from each independent search engine will be concentrated and then returned to the user. The first meta search engine is Master Selberg and Oren Etzioni, Washington University. The Yuan Search Engine conceptually listens, but the search effect is always not ideal, so no yuan search engine has a strong position. The ALTAVISTA (Some users from 2001) are required to access by P-Roxy. No P-Roxy can use QBSEACH radio ALTAVISTA search, only the first page search results can be displayed) is a late arrival, December 1995 debut debut ( Altavista public beta press release. However, a large number of innovative features enable it to quickly reach the peak of the search engine at the time. The most prominent advantage of Altavista is its speed (search engine 9238: more funny, design Altavista's purpose, is said to show only the powerful computing power of DEC Alpha chips). Other new features of AltaVista, always change the definition of the search engine. Altavista is the first search engine that supports natural language search, Altavista is the first search engine that implements advanced search syntax (such as AND, or, not, etc.). Users can search for the contents of NewsGroups and get an article on the Internet, you can also search for text, search titles, search Java Applets, search ActiveX Objects. Altavista also claims that the first search engine that supports the user to submit or delete the URL to the web page index library, and can be online within 24 hours. One of the most interesting new features of Altavista is to search for all sites with links to a URL. On the user-oriented interface, AltaVista has also made a lot of innovation. It offers "TIPS" in the search box area to help users express search gear, these small TIPs are often updated, so that after searching for several times, users will see interesting features they may never know. This series of functions are gradually widely used by other search engines. In 1997, Altavista released a graphical demo system LiveTopics to help users find what they want from thousands of search results. Then arrive in Hotbot. On September 26, 1995, CA Hyache, CA Hyaches, Eric Brewer, and doctoral Paul Gauthier, founded INKTOMI (UC Berkeley Announce Inktomi), on May 20, 1996, Inktomi is established, and powerful Hotbot appeared in front of the world. Requirements to capture indexes per day or more, so far exceeds new content of other search engines. Hotbot also uses a lot of personal search preferences for cookie storage users. (Hotbot was one of the most popular search engines in the next few years, and after being acquired by Lycos) Northernlight was established in Massachusetts Cambridge in September 1995. August 1997, Northernlight Search Engine officially appeared. It used to have one of the largest database of search engines. It does not have Stop Words. It has excellent Current News, more than 7,100 publications with Special Collection, good advanced search syntax, the first support for search results. classification.
(January 16, 2002, Northernlight public search engine closed, then acquired by Divine, but in NLRESEARCH, select "World Wide Web Only", still use Northernlight Search Engine) Before October 1998, Google is just a Stanford University. Small project backrub. In 1995, the Ph.D., Larry Page, started to learn search engine design, registered with Google.com's domain name, at the end of 1997, under the joint participation of Sergey Brin and Scott Hassan, Alan Steremberg, Bachrub starts providing DEMO. In February 1999, Google completed the transformation from Alpha version to Beta. GOOGLE Corporation recognized his birthday on September 27, 1998. Google In PageRank, dynamic summary, web snapshot, Dailyrefresh, multi-document format support, map stock dictionary, search, multi-language support, user interface, etc., like Altavista, once again changed search engines definition. Before 2000, Google has been praised by search accuracy, but because the database is not as large as other search engines, the use value is not very high, and the promotion is not fast. Until the 2000 database upgrade, he was flying in the sky with Yahoo as a search engine. Founded in 1997, FAST (AllTheweb) was a by-product of the academic research of Norwegian University of Science and Technology (NTNU). In May 1999, he released its own search engine AllTheweb. The goal founded by FAST is to make the world's largest and fastest search engine, and a few years ago. Fast (AllTheweb) web search can use ODP automatic classification, support flash and PDF search, multilingual search, also provide news search, image search, video, mp3, and FTP search, have extremely powerful advanced search capabilities. TEOMA originated from a project of the University of Rutgers in 1998. Professor Apostolos Gerasoulis led Professor of Chinese Tao Yang and others founded TEOMA in Piscataway, New Jersey, debut in Spring 2001, September 2001 was acquired by questioning search engine ask Jeeves, released again in April 2002. TEOMA's database is still small, but there are two emotional features: support similar automated classification refine; at the same time provide Resources for professional link catalog. Wisenut was founded by Korean Yeogirl Yun. In the spring of 2001, the beta version was released. On September 5, 2001, a formal version was released, and April 2002 was acquired by the Category Directory Provider LOOKSMART. Wisenut also has two colorful features: WiseGuide, similar to automatic classification and related search terms; Sneak-a-peek for previewing search results. Gigablast was founded by the former INFOSEEK engineer Matt Wells, and the pre-beta version was displayed in March 2002, and the beta version was released on July 21, 2002. Gigablast's database is still small, but also provides web snapshots, a feature function is an instant index web page, your page is just submitted to search (Note: This spammers's meat bag is temporarily closed). OpenFind was founded in January 1998, and its technology is derived from the GAIS laboratory led by Professor Wu Gen, China.
OpenFind onlys only the Chinese search engine. It was the best Chinese search engine. At the same time, the three famous portals Sina, Qi Mo., Yahoo provided a Chinese search engine, but in 2000, the market was gradually divided by Baidu and Google. In June 2002, OpenFind re-released the OpenFind search engine Beta version of Gais30 Project, which launched Polyranktm, announced that the cumulative capture of 35 billion, and began to enter the field of English search, and the technical upgrade is significantly accelerated. Peking Daily Network is the research results of the "Chinese code and distributed Chinese and English information discovery" in the national "Ninth Five-Year" key technology research project. It is developed by the Peking University Computer System Network and Distributed System Research Room, officially in October 29, 1997. Services are served on the CERNET. At the beginning of 2000, Tianwang Search Engine new topic group was established, and the national 973 key basic research and development plan project fund was funded, and approximately 60 million, including education network advantages, with powerful FTP search function. BAIDU, in January 2000, super chain analysis patent inventors, former INFOSEEK senior engineer Li Yanhong and friends Xu Yong (Ph.D., California) found Baidu (BAIDU) in Beijing Zhongguancun. In August 2001, release the baidu.com search engine Beta version (before the BAIDU only provides search engines for other portals Shuoxi Sina Tom, officially released the baidu search engine on October 22, 2001. Although BAIDU only provides Chinese search, it is currently included in the Chinese webpage to more than 90 million, which may be the largest Chinese database. Other features of the BAIDU search engine include: web snapshot, web preview / preview all web pages, related search terms, typographic corrections, news search, flash search, information courier search. After the BLITZEN Project, the technology upgrade was significantly accelerated after the BLITZEN Project. Common Chinese English Search Engine Guide (Drawn) Chinese Search Engine

If you say a search (inserted) L Yahoo search business, Jeff Vaya: "Search business is an integral part of our wider business strategy, not all search services are equally good, only a few search sites Can provide a one-stop search service for users. Now there is a product search website, and there is also a product comparison website. We realize that it is important to integrate search with other services of the company. "L" Search is all secrets of Baidu success, "Baidu President Li Yanhong said:" This is one of the most common services of Internet users, and you can form a lot of influence on users. More and more influence Internet industry, Baidu is an evidence. "Important article: http: //www.ciweekly.com/Article/20031114/20031114272124_1.xml Search Encyclopedia knowledge (inserted) Reference: http://www.sowang.com/sousuo/20031008-4.htm (need to supplement) the principle of search engines, See three steps: grabbound web pages from the Internet → establish an index database → Search Search in the index database. Grab the web page from the Internet - automatically access the Internet from the Internet from the Internet, automatically access the Internet, and climb all the URLs in any web page to other pages, repeat this process, and climb all the webpages Collect back. Establish an index database - Analyze the collected webpage by the Analysis Index System program, extract related web information (including the URL of the web page, the coding type, page content containing keywords, keyword position, generation time, size, and other web pages Link relationship, etc.), perform a large amount of complex calculations according to a certain correlation algorithm, get each web page for the correlation between the page content and each keyword in the hyperlink, and then establish a web index with these related information database. Searching in the index database - After the user enters the keyword search, find all related web pages that match the keyword from the web index database. Because all related web pages have been well calculated for the correlation of this keyword, just sort according to the high-class correlation value, the higher the correlation, the more the rankings are Finally, the page generation system will organize the link address of the search results and the page content summary of the page content summary to return to the user.
