Research On Pragmatic Petri Net In View Of Philosophy Of Science

After the development of the Internet technology to Web 3, characterized by large-scale uncertain network computing and the semantic web as the core has been difficult to meet the increasingly diversified needs of users. Development trend of more and more researchers pragmatic of the intelligent field of Internet's favor, the study of pragmatic theory and pragmatic technologies related to the formation of the problem domain has clear. The Pragmatic Web (Pragmatic Web) global research camp as the core has been formed, how to develop pragmatic technology becomes the key problem of the Internet the next technology leap.Petri C. A. Petri in the inventor of "pragmatic latitude net theory (The Pragmatic Dimension of Net Theory)" the article pointed out:"in the field of semiotics or send and receive information communication science, pragmatics is obviously infinite part of the science, it is Yu Chao more ingrained and sufficiently formalized. Syntax and semantics limitations; pragmatics beyond syntax and semantics that correct sentences as well as its standard" meaning "limitations." Net theory from the very beginning of absorption of some pragmatic theories, it requires:all the resource constraints; the inherent inaccuracy; not completely independent of behavior and decision; wrong idea as its "pragmatic" attitude of existence. Visible, the Petri network from the beginning is pragmatic, or service to achieve pragmatic.This paper introduces the historical development of Petri net, on the basis, analyzes emphatically from the semantic web to pragmatics of Petri net, the from the view of philosophy of science, it reveals that with the Internet becoming more and more intelligent today, pragmatic methodology research has become a necessary theoretical basis in the field of artificial intelligence. Vast repository is one of the advantages of the Internet, network services is a key issue in the new period to promote efficiency of Internet application. As a new type of distributed system, Grid help to coordinate all kinds of hardware and software and data resources to complete a work, compared with the traditional order of calculation, this kind of parallel and concurrent and distributed collaboration system is a fundamental change in computer thinking. As a discrete parallel system, Petri net uses intuitive graphical representation to describe asynchronous concurrent events, with the connection diagram, Petri net changes the description of resources and their quantity in library implementation, and under the rules of caused by changes to implement caused the evolution of the driving state, so as to achieve the aim of system dynamic running process. Therefore, with network service transfers from data abstraction to process abstract, Petri net combines the encapsulation, inheritance, polymorphism of computer programming, at the same time, promotes the systematization and modularization of web services. This not only helps with graphic representation to the user to understand system model, but also promotes the analysis and verification to the corresponding model.This paper argues that pragmatics theory has not yet taken a breakthrough, using the network theory characteristic of Petri network to make up for the inadequacy of the theory, is an effective ways to get their respective breakthrough of pragmatic and Petri net. In the exploration process, how to put the theoretical advantages of the two, in pragmatics on the base of the effective ways to seek fusion, became the key to success. As a result, pragmatic Petri net has the realistic demand and theoretical bases...
