Legal Ontologies for the Spanish e-Government

The Electronic Government is a new field of applications for the semantic web where ontologies are becoming an important research technology. The e-Government faces considerable challenges to achieve interoperability given the semantic differences of interpretation, complexity and width of scope. In this paper we show the results obtained in an ongoing project commissioned by the Spanish government that seeks strategies for e-Government to reduce the problems encountered when delivering services to citizens. Here we present an e-Government ontology model; within this model a set of legal ontologies are devoted to represent the Real-estate transaction domain used to illustrate this paper; some examples of use of these legal ontologies are given.
