Problems solved by technology

[0007] The existing service-oriented requirements acquisition methods [5] often require the service requester to clearly provide the desired service name, input, output and other information, but cannot provide effective support for the abstract requirements of end users. Moreover, when performing dynamic service composition When there is a lack of oriented support, this will make the service composition ineffective

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The examples provided are from the demand acquisition and modeling in the field of urban transportation, and the specific application fields described in the embodiments should not constitute a limitation to the present invention.

[0037] Such as figure 1 As shown, the present invention comprises the following sequential execution steps:

[0038] Step 1. According to common requirements and service resources in the domain, construct a domain model, which includes a domain role model, a domain object model, a domain process model and a domain service model. Common requirements refer to the domain role model, domain goal model and domain process model that need to be established according to common problems. The domain service model is built for existing service resources and is not a requirement. The construction and implementation of all domain ...

Abstract

The invention provides a service requirement obtaining and modelling method based on a domain model, which adopts an analysis method based on the domain model, takes a domain target model form to describe domain similarity requirements and takes a domain process model form to describe a service combination scheme provided for satisfying the similarity requirements. Because user requirements always face a special art, the method of the invention is favourable for improving service combination efficiency. In addition, the invention adopts the domain ontologies technology to improve the capability of supporting diversified user requirement expression forms; interaction with users is favourable for accurately understanding requirements as well as fully reusing domain resources and improving the service experience quality of users.

Description

technical field [0001] The invention belongs to the technical field of computer software, in particular to a domain model-based service demand acquisition and modeling method. Background technique [0002] Requirements acquisition and modeling is an important problem that has plagued software developers for a long time. Bad requirements are one of the root causes of software crisis. Studies have shown that requirements-induced problems occupy an increasing proportion of software engineering. Take the famous Chaos report as an example, the 1995 Chaos report showed that [1] , Among the success factors of software projects, 42% of the factors are directly related to requirements engineering. Meanwhile, 43% of the causes of project failure are directly related to requirements engineering; in a 2003 Chaos report stated [2] , project managers believe that unqualified requirements are one of the main reasons for the failure of software development projects. Across Europe, a sur...
