When integrating electronic negotiations into real-world business processes, an important problem arising is the magnitude of e-business standards in use. In order to support electronic negotiations when negotiation partners use and need to integrate terms named and formatted according to different document standards, taxonomies or similar standards, references between those standards are needed. In this paper, we present a framework for a negotiation support meta-tool which is designed to maintain and dynamically evolve a collection of such references. To deal with semantic ambiguities in different contexts, it provides users with context-sensitive references. The framework uses technologies from ontological engineering and machine learning, its services can be integrated into existing negotiation applications via web services. Furthermore, it allows parameterzation for the actual domain of use.
