One of the most serious challenges that web service enabled e-marketplaces face is the lack of formal support for expressing service requests against UDDI-resident web services in order to solve a complex business problem. We present a framework in which such a formalization is possible by integrating AI planning and constraint satisfaction techniques with web service technology. This framework...

In the telecommunications industry, there is an emerging phenomenon of convergence. Under this convergence phenomenon, the conventional one-service via one-network concept is changing to multiple services via multiple networks. However, our understanding for this convergence phenomenon is vague, thereby resulting in confusion and uncertainty about the market environment. Also, there is limited ...

In this paper we address the problem of planning by composing programs, rather than or in addition to primitive actions. The programs that form the building blocks of such plans can, themselves, contain both sensing and world-altering actions. Our work is primarily motivated by the problem of automated Web service composition, since Web services are programs that can sense and act. Our further ...

Although both men and women have reproductive health care needs, family planning providers traditionally focus services toward women (1,2). Challenges in providing family planning services to men, including preconception health, infertility, contraceptive, and sexually transmitted disease (STD) care (3,4), include their infrequent use of preventive health services, a perceived lack of need for ...

Field service is gaining importance as after sales service is starting to be recognized as a major source of revenue. This motivates planning problems for companies that employ mobile technicians who provide service on clients’ sites. These planning problems share the common characteristic that service levels corresponding to technician response times are explicitly expressed in contracts. More...

While SERVQUAL is the most extensively used measurements of service quality among industries nowadays and its five-dimension measured factors are investigated with respect to the customers’ reaction, E-SERVQUAL thus is developed amid traditional service industries to cope with the internet markets. Both two models use measured data based upon after purchased instead of prepurchased which is con...

In today’s Web, Web services are created and updated on the fly. It’s already beyond the human ability to analysis them and generate the composition plan manually. A number of approaches have been proposed to tackle that problem. Most of them are inspired by the researches in cross-enterprise workflow and AI planning. This paper gives an overview of recent research efforts of automatic Web serv...

The Hierarchical Task Network (HTN) planning method is conceived of as a useful method for Web service composition as well as classical task planning. However, there are no complete successes of service composition by HTN as yet. The reason is the Web service composition process involves the interactive dataflow between variables in preconditions and input/output parameters of services. Since v...

The Web service paradigm allows applications to interact electronically with one another over the Internet. Standards and languages, such as BPEL and OWL-S provide a platform with which Web services can be integrated. Moreover, various AI planning techniques have also been adapted to integrate services. However, the autonomous and distributed nature of an integrated service presents unique chal...
