Using NLP techniques to create legal ontologies in a logic programming based web information retrieval system

چکیده
Web legal information retrieval systems need the capability to reason with the knowledge modelled by legal ontologies. Using this knowledge it is possible to represent and to make inferences about the semantic content of legal documents. In this paper a methodology for applying NLP techniques to automatically create a legal ontology is proposed. The ontology is defined in the OWL semantic web language and it is used in a logic programming framework, EVOLP+ISCO, to allow users to query the semantic content of the documents. ISCO allows an easy and efficient integration of declarative, object-oriented and constraint-based programming techniques with the capability to create connections with external databases. EVOLP is a dynamic logic programming framework allowing the definition of rules for actions and events. An application of the proposed methodology to the legal web information retrieval system of the Portuguese Attorney General’s Office is described.

Modern information retrieval systems need the capability to reason about the knowledge conveyed by text bases. In this paper a methodology to automatically create ontologies and class instances from documents is proposed.

In this paper we present an overview of the PhD thesis, which aims to show the feasibility of a legal knowledge modeling based on the definitions included into legal texts using Semantic Web techniques in order to check compliance of tender documents to EU Directives. We show a hybrid approach, i.e. a theory and a system that combine the use of Akoma-Ntoso standard to describe legal texts, OWL ...
متن کاملSemantic Enrichment of a Web Legal Information Retrieval System
Intelligent text information retrieval systems need the capability to deal with the semantics of the content of their text bases. In order to satisfy this requisite it is necessary to extract semantic information from the documents and to be able to make inferences about it. A methodology to semi-automatically transform a traditional web IR system into a semantic aware one is proposed. The meth...
