Negotiation support systems (NSS) help users in the complex process of reaching agreements about exchange of goods or services. A difficult issue in the development of NSS is how to extract knowledge from qualitative real-life data and embed it into the system. We present a meta-model for modeling domain, user and opponent (DUO) in NSS with focus on four main concepts: issues, preferences, interests and objective domain knowledge. We claim that (a) these concepts are essential in extracting data from unstructured sources, and (b) these concepts can be a basis for formal reasoning about user preferences and bids. We ground our meta-model in negotiation literature and data gathered with case studies and interviews. Finally, we formalize parts of the meta-model as a step towards a computationally-oriented model.
