Abstract

In this paper we propose an application of software agents to provide Virtual Web Services. A Virtual Web Service VWS is a linked collection of several real and/or virtual Web Services, and public and private agents, accessed by the user in the same way as a single real Web Service. A Virtual Web Service allows unrestricted comparison, information merging, pipelining, etc., of data coming from different sources and in different forms. Web Services are accessed according to the standardized protocols and their individual APIs. Public agents are coded in Java and developed by trusted users. These agents are optimized for efficient execution. They are used as mass-usage wrappers, caching utilities, communicators, monitors, etc. Private agents are defined by the agent owners using a specialized, imperative, interpreted, XML-based language. Code of the private agents is optimized for safe execution and mobility. By linking different private and public agents accessing different Web Services, a user may develop individual Virtual Web Services, and thus personalize chosen Web Services to the maximum extend.
