Today, with the continuous maturity of the Internet, where are the new profit growth points? The myth of Google and Baidu on Nasdaq has attracted more and more people's attention to the search engine industry. At the same time, in the era of information explosion, people increasingly rely on a variety of search engines to process network information. Here, I just compare several commonly used search engines, hoping to help you choose and use them.
First of all, Google
The first thing to say is Google, the world's leading search engine. Google cleans up the chaotic information and carefully organizes resources according to the structure of the network itself. Google's search service is more than just a simple information directory. Moreover, the Google Directory contains more than 10 billion websites, which is second to none among similar search engines. The content of these websites is quite extensive.
Different from most other search engines, Google only displays relevant web pages, and its text or links to it contain all the keywords you entered, without being bothered by other irrelevant results. Google can not only search for results containing all keywords, but also analyze the proximity of keywords on web pages. Another difference with most other search engines is that Google determines the order of search results according to the closeness of keywords, giving priority to the results with close keywords, which can save you time without wandering around in irrelevant results. Google is best at finding the most accurate search results for common queries. Among them, the "tm" button is the most distinctive. It will take you directly to the website that best meets the search conditions, which is relatively time-saving and convenient. Google stores snapshots of web pages, and you can still browse the contents of web pages when the server storing web pages temporarily fails. If the server can't be found, the webpage snapshot saved by Google can also be used for emergency. Although the information in the webpage snapshot may not be the latest, it is much faster to find information in the webpage snapshot than in the actual webpage.
Second, Baidu.
As the leader of Chinese search engine, Baidu also has its own unique side. Its information processing method based on the combination of words and phrases has solved the problem of understanding Chinese information quite skillfully, and greatly improved the accuracy and recall rate of search. Baidu also supports mainstream Chinese coding standards. Including GBK (Chinese character internal code extension specification), GB23 12 (simplified) and BIG5 (traditional), and can be converted between different codes.
Baidu's intelligent association algorithm. Using content-based and hyperlink-based methods to evaluate the relevance can objectively analyze the information contained in web pages, thus ensuring the relevance of search results to the maximum extent. Baidu search supports secondary search (also known as progressive search or progressive search) is also a very important feature. You can continue your search in the last search result and gradually narrow the search scope until you find the smallest and most accurate result set. It is beneficial for users to find the content they are really interested in from the massive information more conveniently. There is also Baidu's intelligent and extensible search technology to ensure the fastest and most complete collection of Internet information. With the largest Chinese information database in the world, it provides a solid foundation for users to provide the most accurate, extensive and timely information.
Third, Netease.
In China's search engine market, Netease is also a huge force that cannot be ignored. For other search engines, Netease search also has its own unique characteristics.
First of all, Netease search engine provides multilingual retrieval, and keywords in dozens of languages, such as English, Japanese and Russian, can be directly input into the search box to retrieve web pages. Not just a single language search. Secondly, Netease also has the largest open management directory in China, and about 5000 directory administrators in various industries are responsible for managing website registration information. There are a large number of selected websites in related websites (about 250,000), and the information content of related pages is the largest (about 1 .600 million110,000 pages).
The search principle adopted by Netease is as follows: Netease search engine is a fuzzy search method-the keywords input by users are first analyzed in language, decomposed into multiple words or phrases, and then matched in the data center, so that users may get a result that includes this paragraph of word segmentation, and the result is more abundant; Netease search engine ranks the search results according to the correlation between the search results and the search words input by users. The more keywords users have, the higher the results are. At the same time, the more well-known websites rank higher.
Fourth, Sohu
Sohu is also a good Chinese search engine. Its characteristic is that it classifies information well, which is especially suitable for us to browse and search according to its classification table, but the effect of searching with keywords is not ideal.
Five, SiNa love to ask.
As the first Chinese intelligent interactive search engine, Sina search engine broke through the winning search mode represented by Google and Baidu. It not only retains the powerful function of traditional algorithm technology in conventional web search, but also makes up for the inherent deficiency of traditional algorithm technology in the intelligence and interactivity of search interface with a unique interactive question and answer platform. By mobilizing netizens to participate in Q&A, Sina search engine can gather the wisdom of millions of netizens and let users share knowledge and experience with each other. In order to make the search results more suitable for the actual needs of netizens, Sina search engine has created the function of "direct interaction of content". On the right side of the web search results page, Sina has specially opened up a "direct special zone". If users search for "Faye Wong", Faye Wong's photos, profiles, song downloads and questions and answers about Faye Wong will all appear in the direct SAR; When users search for "slimming exercise", a series of questions and answers related to slimming will automatically appear in the direct area, and the search results will directly give users questions.
