  abstract = {In realistic settings, service descriptions will never be precise
	reflections of the services really offered. An online seller of
	notebooks, for instance, will most certainly not describe each and
	every notebook offered in his service description. This imprecision
	causes poor quality in discovery results. A matcher will be able
	to find potentially matching services but can give no guarantees
	that the concrete service needed will really be provided. To alleviate
	this problem, a contract agreement phase between service provider
	and requester following the discovery has been suggested in the
	literature. In this paper, we present an approach to the automation
	of this contracting. At the heart of our solution is the possibility
	to extend service descriptions with dynamically changing information
	and to provide several means tailored to the abilities of the service
	provider to obtain this information at discovery time.},
