A Requirements Recommendation Method Based on Service Description

The development of Service oriented architecture (SOA) has brought new opportunities to requirements engineering. How to utilize existing services to guide the requestors to express their requirements accurately and completely becomes a new hotspot. In this paper, a requirements recommendation method based on service description was proposed. It can find web services corresponding to user's initial requirements, establish the association relationship between user's requirements and service functions, and in turn, recommend the associated service's functions to the requestor and assist him to express requirements accurately and completely. The effectiveness of this method is evaluated and demonstrated by a case-study in travel planning system.
