A micro-task model for user-oriented semantic service description

Abstract

SOA (Service-Oriented Architecture) has become a popular technology for developing network application. However, the current problem is new service cannot be quickly discovered, orchestrated and composed to match customer needs for insufficient capacity of semantic description of Web services. There is thus a need for an efficient way to describe services from users’ perspective, instead of only realization-oriented description, to make web service the most widely used. This paper proposes a user-oriented semantic service description method which combines task model with semantic service to find a novel way that is suitable and intuitive for a service consumer. A micro-task model is proposed to enhance the capacity of semantic service description from four dimensions: user goal, context, displayed variable, activity; simultaneously, a services description framework based on micro-task model is proposed to accurately map user task into services.
