Web and its technological development

Web1.0 -- Information Sharing
Although people have been fighting for information sharing for many years, information sharing is far from satisfactory until the emergence and gradual improvement of web technology. However, compared with other technologies such as FTP, the self-descriptive model gives the web system powerful vitality, making the web the first infrastructure for information sharing.
Web2.0-Information Co-Construction
In the web era, the information was also unidirectional and sent by the rights group. Ordinary people only have the ability to listen, while Web2.0 gives ordinary people the same right to speak, and consciousness expression is unprecedentedly active, especially in the society where ideology is banned. This will inevitably lead to the proliferation of Network Information: virus traps, anti-virus software has now become the first application of computers; spam information is everywhere, if you find your own information, it will become the needs of Internet users, so the rise of search engines.
However, search engines cannot eliminate trap viruses, distinguish between spam information, or systematize Web information. Therefore, technological exploration becomes inevitable.
Web3.0-knowledge inheritance
Computer is the externalization of human consciousness, and every progress of it will inevitably combine the wisdom of more people. Gathering human intelligence for sharing is the inherent nature of computer science and technology. In web3.0, we should not only eliminate the trap virus, but also get rid of spam information. In addition, we must make a systematic and systematic web world and build a "Web library" based on all web resources, realize the "knowledge inheritance" of humans themselves ".
My knowledge system product is a web3.0 system that realizes the inheritance of human knowledge. Instant messaging is its main feature. Therefore, the instant messaging (IM) system is a technical platform in the knowledge field.
Web4.0 -- knowledge allocation
In web3.0, humans can obtain all kinds of knowledge as they wish. Of course, this knowledge is first contributed by people. The real-time refers to the real-time nature of the teachers who teach students in the school. Starting from web3.0, the network has the instant feature.
However, people do not know what knowledge they should acquire, that is, what knowledge they are suitable for learning. For example, if a 10-year-old child wants to become a nuclear physicist at the age of 20, how should he learn? These problems are the core of web4.0-the problems to be solved by the knowledge distribution system.
Web5.0-pragmatic Network
When it comes to pragmatic networks, I have truly entered my research field. Although the development of technology is dazzling, the essence behind it is very simple. The existing computer technology is based on the Turing Machine Model. Simply put, the Turing machine is mechanized, Program Or arithmetic, which is a closed theory system with a data and operator (operator) of 2 yuan. A Turing machine is a mathematical science that studies and defines the operator laws or rules on a dataset.
In the online world, this closed system must be combined to become a whole. The so-called entire network becomes a computer system. This computer is no longer a Turing machine, but a Petri net. As long as more than 20 years ago, Petri net has said that the computer system technology for implementing Petri net is called pragmatic. Therefore, the pragmatic network is the technical basis of this computer.
