A Request Language for Web-Services Based on Planning and Constraint Satisfaction
نویسندگان
چکیده
One of the most challenging problems that web-service enabled e-marketplaces face is the lack of support for appropriate service request languages that retrieve and aggregate services relevant to a business problem. We present an architectural framework for web-service interaction based on planning and constraint satisfaction, and a webservice request language (WSRL) developed on the basis of this framework. This framework is capable of performing planning under uncertainty on the basis of re nement and revision as new service-related information is accumulated (via interaction with the user or UDDI) and as execution circumstances necessitate change.
