What are the third generation search engines like, and which ones are mainstream?

Shunfeng's "Holographic Search Theory" mentioned that the future search engine should focus on the balanced development of "human nature", "social environment" and "search technology and environment". At present, very little has really been done, just theory!

We'll see

There are tens of billions of Chinese pages included, and the number of these pages is growing at a rate of tens of millions every day. At the same time, the servers are distributed all over the country, which can directly feed back the search information to the current users from the nearest server, so that users can enjoy a faster and more convenient search experience.

360 search is a full-text search engine and is one of the mainstream search engines that are widely used at present. 360 search includes web pages, news, movies and other search products, which can bring users a safer and more authentic search service experience.

360 search has a strong search technology, and has tens of thousands of servers, huge spider crawlers crawl hundreds of millions of pages every day, and hundreds of millions of high-quality pages are included, and the page search speed and quality are also very high.

4. Google. Google is the world's largest search engine, one of the most popular on the Internet, and has a large user base. Google has won the approval of users with its simple, clean page design and the most relevant search results.

The third-generation search engine is developed by the R&D team of Xinhua Yunke search engine, and the distinctive feature of the third-generation search engine is that it is based on natural language search and intelligently returns search results. The first generation of search engines is directory search, and the second generation of search engines is keyword search. For details, please log in to Xinhua Cloud.

The main characteristics of the second-generation search engine are keyword-based search, as well as full-text search and fuzzy search based on keyword combinations. Compared with the first generation of search engines, the advantages of keyword-based search are that it is easy to use, the search speed is fast, and the content is directly searched, which is incomparable to the first generation of search engines.

The main feature of the third-generation search engine is that it is based on natural language search, and users no longer have to stick to traditional search methods such as keywords, titles, authors, time, and categories. Using regular natural language, you can search for what you want.

Now it's the second generation.

The first generation is to use human power to classify ** information into catalogs. Make it easy for users to find and use. The second generation is to notify the robot spider to crawl and grab Internet information and automatically establish an information database. Of course, there are more complex algorithms in it.

The third generation is to accurately analyze the user's demand information through artificial intelligence, and then give answers. And the way is whether it is **, voice, or text. Of course, there will still be an information database on the backend to support it.

However, this database will not be a single node in the future, but multiple nodes distributed across the globe and even the universe.

The main manifestation of the third-generation search engine is the 3G network, and the 3G** derived from it has been recognized by many enterprises. 3G** not only has SMS and MMS access, but also can be bound to various ** domain names.

The first generation of search is a classified directory search that mainly relies on manual sorting, marked by Sohu and Yahoo; The second generation of search is a web search that relies on machine scraping and is based on hyperlink analysis.

Interactive search: In the process of human-computer interaction between the user's query and the search engine's return results, the engine intelligently uses multiple groups of related topics to help users quickly find relevant search results according to the user's query content.

Precise relevance: Advanced word segmentation engine, and uses Sohu's 40 million usernames to optimize the name recognition of the word segmentation engine. In the query results, the page is culled that contains only the link text.

The amount of web page data for query words includes 200 million Chinese web pages, exceeding the amount of Google index.

The main features of the second-generation search engine are the use of "symbol computing", search based on key (word) words, and full-text search and fuzzy search based on keyword combinations. Compared with the first generation of search engines, the advantages of keyword-based search are that it is easy to use, the search speed is fast, and the content is directly searched, which is incomparable to the first generation of search engines.

The application defects of the second-generation search engine, users are looking forward to the advent of a new-generation search engine that is faster, more accurate, and more convenient. This is exactly the direction, goal and development trend of the second generation of search engine technology, and many companies are trying it. According to Tencent Technology on March 15, 2012, Google plans to use semantic search technology to upgrade its search engine.

Although this is theoretically described, its application value has yet to be judged by user experience, and there is no alternative technology of "keyword search", it can be determined that the use of "language computing" technology, based on natural language search, and intelligent return of search results, is a new trend in the development of the second generation of search engines.

On October 19, 2011, China Search officially launched the open third-generation search engine platform, the search results meet the comprehensive, accurate, intelligent, interactive and beautiful CIVIA search standards, on this platform, to achieve the integration of various cross-industry, cross-regional, cross-information categories and cross-display search services.

The third-generation search engine platform is the world's first open search platform that combines search technology with human intelligence, professional knowledge and search technology. Through in-depth cooperation with excellent partners in various industries, professional knowledge and search technology are organically integrated, and users are provided with more comprehensive, accurate and feasible search results according to their needs. The search results provided by the third-generation search engine platform are no longer a simple information presentation, the results themselves can become an interactive platform, through the application of widgets, the rich means of expression of the result page will also present a different visual impact and expressiveness.

At the same time, it also proposes a new search standard, that is, the five standards of civia, which are comprehensive, accurate, intelligent, interactive and beautiful, and the search content that meets this standard can become one of the contents of the third-generation search engine platform.
