Problems solved by technology

However, most of the commonly used requirements decomposition methods do not consider the user's preference for the requirements decomposition scheme
It also does not consider the specific field of service composition. A large number of available services provide a wealth of information, such as their scale, which can be used to control the granularity of demand decomposition early, avoiding excessive breakdown of demand and wasting manpower and material resources. , and it is not easy to match in service selection

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0023] Service-oriented requirements analysis and service discovery mostly use I / O matching: if the output of a service contains all the outputs required by a certain sub-requirement, and the input of the service is known, then the service is said to be It can realize the function of this sub-requirement. Requirements decomposition is to decompose and refine complex user requirements, so that each sub-requirement can be realized by existing services.

[0024] The concrete steps of the inventive method are:

[0025] 1) Model the user needs, and abstract the user needs into a seven-tuple R=ID, I R ,O R , Pre R ,E R ,W,P, where ID is the ID of the requirement, I R is the input parameter set (I R = I 1 , I 2 , I 3 , I 4 ,...,I n , the elements in this collection are all input elements. n is the number of input parameters, OR is the output parame...

Abstract

The invention discloses a service-oriented demand analysis method. The method includes the steps that first, a user need is abstracted to be a septet, an existing web service is preprocessed, and then whether demand analysis is needed or not is judged according to the semantic distance of the septet and meta services; when the demand analysis is carried out, the relevance among the meta services is selected first, afterwards, needed paths of all output parameters for obtainment of the user need are searched, and the paths are fed back to a user after being ranked from high to low according to user satisfaction. According to the method, the existing service is utilized, the need is decomposed on purpose, granularity control is carried out as soon as possible, so that the need decomposition process is completed as early as possible, an efficient decomposition service can be provided, and a colored petri net model is established.

Description

technical field [0001] The invention belongs to the field of computers, and relates to a demand engineering method and a user preference retrieval method. Background technique [0002] Web services are self-composing and self-describing, can be published on the network, and can be called dynamically. The value of Web service lies in the reuse, which makes the service add value. Web service composition combines existing small-grained web services with different functions to form more powerful large-grained services, thereby realizing complex user needs. Service composition improves the reusability and maintainability of services and saves a lot of time and resources. It has been extensively studied in recent years and has become a research hotspot in the field of service-oriented architecture (SOA). However, user requirements are usually abstract and general, while the description of existing services is very specific, so requirement decomposition is very important. Only w...
