Professor Dr. Guido Boella of Università degli Studi di Torino Dipartimento di Informatica, and colleagues, have published Using Legal Ontology to Improve Classification in the Eunomos Legal Document and Knowledge Management System, in LREC 2012 Conference Proceedings: Semantic Processing of Legal Texts (SPLeT-2012) Workshop, pp. 13-20.
Here is the abstract:
We focus on the classiﬁcation of descriptions of legal obligations in the Legal Taxonomy Syllabus. We compare the results of classiﬁcation using increasing levels of semantic information. Firstly, we use the text of the concept description, analysed via the TULE syntactic parser, to disambiguate syntactically and select informative nouns. Secondly, we add as additional features for the classifier the concepts (via their ontological ID) which have been semi-automatically linked to the text by knowledge engineers in order to disambiguate the meaning of relevant phrases which are associated to concepts in the ontology. Thirdly, we consider concepts related to the prescriptions by relations such as deontological clause and sanction.
