Research output: Chapter in Book/Report/Conference proceedingPublished conference contribution


Contracts formally represent agreements between parties and often involve the exchange of goods or services. In contracts, clauses define the behavior
expected from parties in terms of deontic statements such as obligation, permis-
sion and prohibition. These normative clauses may contain conflicting deontic
statements referring to the same party in the same context, producing inconsis-
tencies in the normative structure of the contract. Our main contribution is an
approach to detect potential conflicts between norms within contracts written in
natural language. We use a rule-based approach and natural language process-
ing, which result in promising empirical results. This constitutes a first step into
automated processing of contracts in natural language.
