The arrival of Web2.0 times, what can you bring to search engine? I think the most important is to provide a kind of new content source, namely the content that the user creates (User Generated Content, UGC of the following abbreviation) .
The network effect that UGC has a kind of community spy to have (Network Effect) . Be in the United States, the growth of a lot of websites is very rapid, produced this kind of specific effect of community website adequately namely. Network effect is reflected in, the user that should join community is more, contributive content is more, every user gets benefit also is jumped over tall; And, when community user number and content quantity obtain quantity of a crucial point (Critical Mass) after inflection point, website user is counted and the acceleration of several growth meets content to greaten gradually, till final hasten delay.
To search engine, UGC is not a simple card on traditional sense, the customer of a rich that perhaps keeps, it includes two parts content at least: It is socialization media above all (Social Media, the concept that here media is broad sense) , you can upload your photograph, or video of a paragraph of DV. Next, founding this content when the user while, also can all alone to search engine provides a lot of new auxiliary data, the metadata that often says namely (Meta Data) , these metropolises are alled alone by search engine place is used.
The United States ” news weekly ” there once was a famed cover implied meaning April this year, caption cries ” the Internet that is a center with us ” (Putting The ‘ We ‘ In ‘ Web ‘) . The flying development that the is core with UGC namely Web 2.0 site that the article describes is in the United States, more typical case isMySpace, FlickrAndYouTube.
What I lift an example to come to those who show Web 2.0 community website grow is fast. The photograph that Flickr is an abroad shares a website (note: ” news weekly ” the author that magazine cover photograph is Flickr: Stewart Butterfield and Caterina Fake couple) . Flickr is the small website that Stewart builds for wife Caterina only at first, but the user as the website is increasing, and website itself takes the user seriously of the experience highly, public praise effect and network effect get be reflectinged stage by stage, development is very rapid. March 2005, flickrBe bought by Yahoo. After 1 year, it every day PV is in 20 million above, grow 4 compared to the same period times; The month visits user number to be in independently 12 million above, grow 9 compared to the same period times; And the amount of photograph label accumulative total has been achieved 260 million. This development speed is quite breathtaking.
The occurrence of Web2.0 website, can produce the effect of essential sex to netizen lifestyle. The stickiness of Web2.0 website is very strong, they and traditional portal site are different, user feature is more apparent. This is an analysis of American Internet online behavior August, everybody can see, be in right next horn, the portal site that is a tradition (include Yahoo, MSN and AOL) , they are the site that often uses among netizen life, the day number that body visits them every months in the netizen now is maximum, keep above time every day the longest, the webpage amount of the visit is maximum also. Among lower part is search engine (Google) , the user is very tall also to its visit frequency, but retention period is the briefest. Wrong upper part is new occurrence Web2.0 website (MySpace, facebook and Cragslist) , although the netizen is right,these websites use frequency every months opposite at the portal not tall, the user visits these websites impossibly every day, but the stickiness of these websites wants far outclass to search engine and portal, the growth of UGC whole is very breathtaking.
We will see the progress of Chinese Internet. Graph of this piece of trend combined the statistical data that Ai Rui and CNNIC release, our country now broadband user year the growth that increase rate outstrips integral netizen, the broadband has made the online way of a mainstream. To the end of 2007, internet permeability will be achieved 12% , among them broadband user scale is as high as 63% . We also see, because of the growth of netizen amount, with the addition of netizen online experience, add a broadband gain ground, of domestic and international VC a large number of gathering, make website of this kind of Web2.0 is in UGC development rate of China is very rapid. Among this although a lot of websites are right of foreign trade pattern duplicate, but the meeting after believing period of time chooses through the market truly ecbolic an a few valuable Web2.0 website.
As a result of diversity feature of the netizen, prospective community cannot be a website alone big, build a diverse community by different website however, will satisfy different user and application. It is from community user in light of the scale among whole netizen, this growth is very fast. Arrive to did not come from 2005 2010, integral netizen amount and community user number rise in year after year. To 2010, number of domestic community user will be achieved 140 million, the netizen that exceeds 6 to become will become the member of community. So much netizen, community user of so much, bring engine of all alone giving search what kind of change. Differ with traditional website stationmaster or the content that edit dominant, the many UGC that community user creates will bring double property, its are subjective with personalized colour will stronger.
Will look from this meaning, web2.0 will bring a socialization to search (Social Search) times. The course that search engine development is below pursues. Just began, it is at the beginning of 90 time, it is only inside university and scientific research orgnaization, very few one part user is using search engine. Was 1994 next the issuance of Yahoo catalog, represented those who face common popular to search engine to be born. The amount as the webpage from 1 million break through to one billion four hundred and ten million and sixty-five thousand four hundred and eight level, google and Inktomi begin to appear, the network that arose to be based on the technology such as analysis of index of spider capture, full text, link searchs engine. And future, the times that is search of a socialization. The stationmaster that the content that we should face is a tradition no longer and the content that edit a generation, wait by the rich customer that initiative place keeps the user or uploading photograph however, this will be the new content that search engine should pay close attention to. Socialization search needs compose to build the platform of good community, accumulate and assure the incentive mechanism of quality what have crucial point amount even. On the net, the netizen’s content is created often very active, but very subjective also. What new search service needs to dig the magnanimity in UGC through mechanism and technology is clever.
Below my general comes with two products of Yahoo illustrate the exploration that we search to socialization.
The first example is the intellectual search of Yahoo, it had formed the intellectual network of globalization at present, include to be in chinese mainland, taiwan province, japan, the United States, the market such as South America and Europe, we have a such knowledge to search platform (note: Yahoo knowledge search cries in homeIntellectual hall, cry in English countryAnswers) . Use a such platform, what we can develop global netizen actually is clever. Be in for instance this year August 11, hollywood’s famed movement piece director Wu Yusen searchs the netizen to world each district to ask through Yahoo knowledgeSame a problem: “Why are we always obsessed with the hero in caricature to be very happy with it? ” this problem is released to China, United States, England, Singapore at the same time, argentine, on the website of the Yahoo various places such as Spain. We got the area differs very quickly coming from differring a large number of answers of the netizen of culture setting, be in Yahoo China for instance, we got 3284 answers and 1067 reviews. This example can explain, the mode that a lot of subjective knowledge can search through socialization will get, this is impracticable of traditional search engine.
In addition, return the search experience that can improve statement of knowledge and problem crucial point through UGC. When we are using a webpage to search, after the crux word that inputs a specific type, can return Yahoo knowledge hall inside the netizen’s answer, complement as. Such, search engine can find a result through algorithm not only, also can pass complement these answer side users find contented solution.
The 2nd example is socialization bookmark (Social Bookmarking) . Everybody knows, traditional search engine has a limit, no matter who the user is,be, the result of the search is same. To objective, the crucial point word that is based on a fact, search engine can provide better result commonly, and to subjective, the crucial point word that is based on individual viewpoint, search engine is helpless, also cannot provide the result of high quality commonly, flat perhaps without the result. Our statistic discovers, the user that has 1/3 about inquires crucial point word, contain subjective colour, cannot achieve contented result through traditional search method that is to say. Yahoo rolls outCollect Product, pass netizens to the webpage between is collected and be shared namely, will make up for a tradition to search algorithmic inadequacy. For example, collecting inside search ” Web2.0 ” , discharging those who be in the first is the masses comments on a net, it is be collected by Yahoo user most, reflected netizens’ unanimous view, this and the result that common webpage searchs are disparate.
Sum up the Web2.0 influence to the search, we think to have at 2 o’clock: The first, the knowledge that the user that Web2.0 will offer the high quality that has crucial point amount for traditional search service produces and content; The 2nd, traditional search can pass the knowledge in using UGC and source data, come the improvement of dominance searchs an experience. This will be search engine after surmounting technology of traditional Information Retrieval surmount again, reflected it is with the person this search attempt.
Finally, I share Yahoo to search the understanding of the mission to future with everybody, we are its abbreviate a wordFUSE, english is shirt-sleeve meaning, but the abbreviation that actually it is 4 movements: It is Find above all (find) , we should help people find them to want the information that seek; It is Use next (use) , we should help an user achieve the task in they work or living or goal; It is Share then (share) , help you and friend share knowledge together, perhaps find new friend in share; Finally is Expand (patulous) , use all netizens clever will abound global information knowledge base. Search engine centers in before solving two problems so: Find and use; When Web2.0 times when UGC is more and more important, search engine pays close attention to two problems after solving more, help netizens are shared and expand namely knowledge. (be over)

2, last week 3, below the formidable competition pressure that searchs in Yahoo knowledge, google shut service of his interlocution paying fee, reflected the success that the socialization below Web2.0 searchs from a flank.
