Hierarchical quantitative measurement service process-to-process distance system

Abstract

The invention relates to a hierarchical quantitative measurement service process-to-process distance system, belonging to the field of computer application technology. The system comprises a process conversion module, a relevant node matching module, a modified path tree computation module and a distance computation module, wherein the process conversion module and the relevant node matching module are connected to transmit the structured process tree information of two converted processes to be compared, the relevant node matching module and the computation modified path tree computation module are connected to transmit the structured process tree information of the two processes with matching information, and the computation modified path tree computation module and the distance computation module are connected to transmit the structured modified path tree information. The modified path tree between processes is computed by matching relevant nodes in the structured process tree of the processes, the measurement of distance between the processes in different hierarchies is realized, and the invention has the advantages of quantification and multiple views.

Description

technical field [0001] The invention relates to a system in the technical field of computer applications, in particular to a hierarchical quantitative measurement system for distance between service processes. technical background [0002] With the large-scale application of service processes as a means of integrating services, how to manage, retrieve and reuse service processes has gradually become one of the core contents in service computing, and measuring the distance between service processes is one of the key technologies. Based on the differences between service processes, service processes can be classified and stored in an organized manner for easy management; a reliable standard can be provided for the retrieval of service processes; Data mining of the differences between them can provide the experts who define the model with the changing dynamics of users' needs and help them formulate more reasonable service processes. In this case, constructing a good system fo...

Problems solved by technology

[0003] After searching the existing literature, it is found that the imprecise process matching method proposed by Zhuge Hai in "A process matching approach for flexible workflow process reuse" is a typical example (Information&SoftwareTechnology, 2002, 44(8), P445-450), This paper introduces the concepts of activity ontology and process ontology, so that the process can be reused more freely, but this technology is only based on the comparison of graph nodes, so it cannot be systematically compared from the deep logic of the process

[0004] After searching the existing literature, it was found that W.M.P. van der Aal st et al. proposed a method of comparing two processes based on the typical behavior of the process in the article "Comparing Two Process Models Based on Observed Behavior" (Proceedings of the 4th International Conference on Business Process Management, Vienna, Austria, 2007), this technique ignores some atypical behaviors, and it is a complex process to determine and compare all the typical behaviors of two processes, yet the obtained results only describe the differences in the behavior of the two processes , it is impossible to intuitively give what changes need to be made to transform one process into another process, and there is no quantitative calculation of the difference between the processes

[0005] After searching the existing literature, it was found that in the article "On Measuring Process Model Similarity based on High-level Change Operations", Chen Li proposed to find the difference between the processes based on the process itself, and the revised paper solved the problem that does not exist in some systems. The process modification log problem, but this technology does not compare the two processes hierarchically, and cannot compare the differences between the two process models from the perspective of different levels
