Leading U.S. financial magazine "Fortune" online edition published an article Wednesday said the number of U.S. search engine service providers have been great efforts to develop real-time (real-time) search service to meet Twitter, Flickr and other blog-specific search needs of site users; but real-time search to really meet the actual needs of users, the search engine developers have a long way to go.

Real-time search

For major events around the world, the United States is playing a mini-blog site Twitter timely release of the latest news from the role. Twitter users to include a brief news release, pictures and video (for longer content, then publishing the contents of the corresponding link) and so on. Since these elements will continue to continue to update, many users need to quickly search the vast amounts of information to their own wish to see. This is called real-time search.

However, real-time search is the biggest problem currently facing: the face of continuous updating of the various types of real-time information from the search engine is difficult to filter out reliable information of practical value, and those fake, spam excluded.

In fact, whether it is Twitter, Facebook, or Flickr, and other blog sites, are faced with real-time information too much, too messy challenges. Because these platforms allow users to self-publish a variety of content, leading to the really important information will soon be submerged in a large number of these worthless spam.

Market prospects

Even the search giants like Google, does not say they have solved the real-time search problem. In May this year, Google held the spirit of the times (Zeitgeist) technology conference, Google co-founder Larry Page (Larry Page) admit that in real-time search business, Google is still not developed much real practical value of the products and services. As Twitter has launched its own search service, Page admitted that Google is behind real-time search Twitter.

See real-time search in the huge market growth potential, the U.S. has reached a number of technology start-ups in the business, including Collecta, OneRiot and Scoopler and so on. These start-up companies want to solve an industry problem: how to make the current Internet users quickly learned that the most popular events and topics that? After all, almost every week, the Internet, the latest hot topic will appear.

Leading U.S. market research firm IDC analyst Hadley Reynolds (Hadley Reynolds) which said: "how to provide good real-time search solutions to issues, Microsoft and Yahoo have to take some time. In this way, Those engaged in the development of search engine start-up companies will be able to seize the business opportunities. "

Technical problems

However, to really solve the real-time search problem is not easy. In the field of real-time search, the search engine on the one hand to provide the latest, most popular information; the other hand, the user will proceed from their own subjective that the most important other events. Thus, the popular topic with the subjective will of the conflict will become apparent, and search engine service providers can not this come up with a perfect solution.

Search for information in real-time screening of the way, the most simple way to let the time to make a choice. However, if the search engine to authoritative content providers, content distribution scope of the standard as a screening method, the search engine is likely to miss some very valuable information - even though this information has not been outside the original concern.

Twitter, for example, the site released a wealth of information updated daily. During the past year, Twitter launched a search service called Summize, the information filtering method is to time as the standard. Not long ago, just on the line Collecta, but also time as the information filtering criteria, but will also focus on other blog and social networking sites related to the release of information.

Long way to go

But only with time as the standard, may not be regarded as a real-time search of the best screening methods. Scoopler other search engine start-up companies have developed a new algorithm: just grab the recently released information, but also those who will grab the most popular information. If OneRiot to developed a product called PulseRank, it can track the real-time information released by the "freshness" of information submitted by the authority and the information dissemination.

 cheap uggs

But now, the new real-time search engine are not on the mainstream stage. The reason the one hand, these search engines is poor user interface, ease of use; Second, the corresponding results have little practical value.

For example, two days before the Nasdaq Stock Exchange former chairman 席伯纳德马多夫 (Bernard Madoff) jailed for 150 years after the news spread, the real-time search engine users type in tramadol After her husband's key words, but did not find the news of 150 years imprisonment, but the sooner the "old news." From this, real-time search engine to truly meet the needs of users, there is still a long way to go. (Compilation / the Tao)
