Extracting normative relationships from business contracts
نویسندگان
چکیده
The normative concepts offer a principled basis for engineering flexible multiagent systems for business and other crossorganizational settings. However, producing suitable specifications is nontrivial: the difficulty is an obstacle to the adoption of multiagent systems in industry. This paper considers normative relationships of six main types, namely, commitments (both practical and dialectical), authorizations, powers, prohibitions, and sanctions. It applies natural language processing and machine learning to extract these relationships from business contracts, establishing that they are realistic and their encoding can assist modelers, thereby lowering a barrier to adoption. A ten-fold cross-validation over more than 800 sentences randomly drawn from a corpus of real-life contracts (and manually labeled) yields promising results for the viability of this approach.

A simulation approach to design contracts that govern emergent multi-agent systems
Agent-based normative systems offer the potential for a business to model, understand the consequences of, and then refine contracts to improve the outcomes for that business. In this paper, we combine a simulation technique designed for investigating and tuning emergent behavior in multi-agent systems with an approach to modeling norms of the complexity found in business contracts. We believe ...

متن کاملSocial control in a normative framework: An adaptive deterrence approach
Normative environments are used to regulate multi-agent interactions, by providing means for monitoring and enforcing agents’ compliance with their commitments. In business encounters, agents representing business entities make contracts including norms that prescribe what agents should do. Agent autonomy, however, gives agents the ability to decide whether to fulfill or violate their commitmen...
