Alessio Antonini of Università degli Studi di Torino has posted Temporal Network of Norms: A middle level between formal rules and legal practice, a poster given at SSSW 2013: Summer School on Ontology Engineering and the Semantic Web, held 7-13 July 2013 in Cercedilla, Spain.
Here is a summary:
What is a norm? Part of the current research in AI and Law is based on the strong assumption that norms can be modelled as rules and that such rules can be extracted from the legal text only. Thus, rules are typically considered as given and from this assumption a formal theory of law in terms of rule reasoning has been given with the formal means at disposal up to now. However, in legal practice, the norm is not exhausted by rules extracted from the legislative text, but it is something that emerges from all the legislative system, the interpretations, the judgments and in general from the whole social system around norms. […]

Norms is not exhausted by rules extracted from legislative texts but emerge from legislative system, interpretations, judgments and in general from the whole social system.
1) multiple representation of concepts (ontologies, rules)
2) distinction between use and description of concepts
A flexible representation of agents’ actions that does not require strong assumptions about norms’ content and agents’ actions.
It is necessary to assume a granularity of the representation: the level of details that can we acquire through source analysis.
Agent interpretation of social objects
1) Agent extraction of information from social objects
2) Agent interpretation of roles
3) Creation of social expectation […]
