As the Internet becomes widespread, many companies have started to present their services through the internet to reach more customers. They have increasingly been using web services in their applications to cope with the complexity and heterogeneity of the Internet. Companies not only sell, but they also buy services over the internet. We present a new web services market framework implemented through role based agents to provide a suitable and efficient infrastructure for presenting, selling and buying web services. This paper describes the design and implementation details of a framework named agent web service market (AWSM) and a new role based agent model. In AWSM, companies are represented by agent societies which are composed of agents that possess roles to reflect companies' dynamic structure. A role is a collection of services which can be taken and left dynamically by agents at runtime. The structure of a role can also change during execution time. Depending on their roles, agents gain the ability to provide services, which they can register as web services. A client in search of a particular web service can look up for web services provided by agents on the. The client requesting the web service also provides service information, service level parameters and cost criteria. The framework puts out a tender to determine a web service that meets those criteria.
