In this paper we present a Description Logic approach --fully compliant with the Semantic web vision and technologies-- to extended matchmaking between demands and supplies in a semantic-enabled Electronic Marketplace, which allows the semantic based treatment of negotiable and strict requirements in the demand/supply descriptions. To this aim we exploit two novel non-standard Description Logic inference services, Concept Contraction --which extends satisfiability-- and Concept Abduction --which extends subsumption. Based on these services we devise algorithms, which allow to find negotiation spaces and to determine the quality of a possible match, also in the presence of a distinction between strictly required and optional elements. Both the algorithms and the semantic-based approach are novel, and enable a mechanism to boost logic-based discovery and negotiation stages within a e-marketplace. A set of simple experiments confirms the validity of the approach.
