ABSTRACT
Electronic contracting is key issue for establishing liquid markets dealing with electronic goods. This paper presents a framework for automatic negotiation between Web services. The major goal of the framework is comprising all necessary components for negotiation and re-negotiation. The capabilities and the components are described both for Web service consumer and provider. The re-negotiation framework is based on independent control loops and associated knowledge bases for consumer and provider implementing specific business strategies. An economic cost model considering variable cost and a business rule repository are main parts of the knowledge bases. Furthermore the framework can handle auctioning by using predefined workflows as so called auctioning plug-ins.

Recommendations
An Adaptive and Intelligent SLA Negotiation System for Web Services
The effective use of services to compose business processes in services computing demands that the Quality of Services (QoS) meet consumers' expectations. Automated web-based negotiation of Service Level Agreements (SLA) can help define the QoS ...
Workflow composition of service level agreements for web services
Service-oriented architecture enables an environment where businesses can expose services for use by their collaborators and their peer organizations. In this dynamic environment, organizations require the use of service level agreements (SLAs) to ...
The WSLA Framework: Specifying and Monitoring Service Level Agreements for Web Services
We describe a novel framework for specifying and monitoring Service Level Agreements (SLA) for Web Services. SLA monitoring and enforcement become increasingly important in a Web Service environment where enterprise applications and services rely on ...
