1. Law and Justice in a Global Society Artificial Intelligence and Law Ontology and Philosophy of Law: from REIMDOC as example Fernando Galindo University of Zaragoza Granada, 25th May 2005

2. Summary Abstract of the paper REIMDOC: object The example: first steps Ontologies Philosophy of Law Consequences Conclusion

3. Abstract of the paper Paper as concrete example of the use of ontologies as tool for knowledge representation in Artificial Intelligence applications Philosophy of Law as adequate tool for the development of ontologies The proof of the theories is the study of a concrete case related to the making of a software programme of industrial character adequate to integrate and retrieve juridical documentation, using several languages

4. REIMDOC: object From a philosophical point of view: study of juridical transactions in the ICT society (best as the knowledge society) Procedures related with: 1) the elaboration of private agreements for the acquisition of real state property 2) their formalization to be included in the property registers, payment of tax in the tax Administration and solution of possible conflicts by the Administration of Justice (Judges) as examples The study as begin of the construction of REIMDOC: system of multi lingual retrieval and integration of juridical documents

11. Conclusion The example has as objective the development of theories and practical examples for E Government, this is the access to the Public Administrations by the citizens using technological systems The point of departure is the access to documentation referred to the acquisition of properties: houses or appartments. It is enough easy (formal) and complex for the development and proof of systems of E Government The idea is to plan and design adequate procedures and programmes to build, formalize and send securely, documents made by citizens to the Public Administrations The activites are possible thanks to the adequate philosophical reduction of the example. It opens the door to put in practice all necessary resources for this kind of research
