SWAM: A logic-based mobile agent programming language for the Semantic Web

Once a big repository of static data, the Web has been gradually evolved into a worldwide network of information and services known as the Semantic Web. This environment allows programs to autonomously interact with Web-accessible information and services. In this sense, mobile agent technology could help in efficiently exploiting this relatively new Web in a fully automated way, since Semantic Web resources are described in a computer-understandable way. In this paper, we present SWAM, a platform for building and deploying Prolog-based intelligent mobile agents on the Semantic Web. The article also reports examples and experimental results in order to illustrate as well as to assess the benefits of SWAM.

Research highlights
► A standard complaint (OWL and Web services) mobile agents development platform based on logic programming.
► The discovery and matchmaking of agent resource requirements against available resource instances can be automatically supported using first order logic.
► A generic, tailorable mobile agent execution model (GRMF) that automates many mobility decisions while allows developers to supply protocols for dynamically adjusting mobility according to the nature of agents.
