The Research On Construction Of User’s Requirement-oriented Personalized Process

With the popularity of Internet technology, there are abundant of online web servicesand resources available. Users want to reorganize the spread resources and services toprovide personalized service according to their needs. However, the traditional process ismainly for business users, and the process is customized in advance in accordance withbusiness needs. While the requirements of ordinary users are different, the traditionalprocess cannot meet the needs obviously. Personalized service needs the support ofpersonalized process model. Personalized process model is dynamically generated onuser’s demand, and the variability of the process brought by the change of user’srequirement can be achieved.The focus of this study is the construction of the personalized process in personalizedprocess application mode with tourism as the background. This paper elaborates the logicarchitecture of the personalized process model which consists of the process logic layer,the functional logic layer and the specific function layer. The platform architectureincluding personalized process generation module, service community managementmodule and personalized process execution module is also described.The process logic and functional logic is separated, which is the most significantfeature of the personalized process model and is the biggest difference between thetraditional process and the personalized process. In the process logic level π-calculus isused in personalize process modeling. In response to user’s changing demand, this paperproposes a process changing description model, and indicates a formal representation ofthe process change. Finally, this paper use MWB and π-calculus bisimulation theory toverify the correctness of the modeling. In the functional logic level service community isthoroughly illustrated to manage the existing service using a virtual resource pool, it meansthat web services which have the same or similar function are put into the same servicecommunity. The service registration and service matching method based on servicecommunity is also illustrated which can facilitate web service discovery and matching and thereby increase the speed of execution of the process.Based on the theories we talk about, this paper introduces the construction practice oftourism personalized process in the form of instance. The first is the introduction of userrequirements capture mode, and then based on the user needs the process is modeled withπ calculus, and process change is analyzed. Finally, the personalized process is mapped toBPEL language, and is consigned to process execution engine to execute.In this paper, personalized process is suitable for service combination and processapplication in Internet. Process modeling method and service organization method havepractical significance for process generation methods innovation. This study is useful forthe establishment of a tourist application which can easily meet the individual requirementsof tourists. And it will also provide a reference for process automation services of otherrelated services industry.
