We study law enforcement mechanisms within a population of norm-governed learning agents. We show that a traditional analysis based on expected utility can be misleading, because learning agents tend to comply even though their surveillance is stopped. This has significant implications for the design of self-organising institutions with endogenous resources, where the cost of monitoring and norm enforcement has to be taken into consideration.

We investigate ex ante law enforcement within a population of norm-governed learning agents using a probabilistic rule-based argumentation framework. We show that this formal framework can advantageously complete a traditional analysis based on expected utilities, in particular when hyper-rational or omniscient agents are not assumed. This has significant implications for the design of self-organising electronic institutions, where the cost of monitoring and enforcement of laws and norms has to be taken into consideration.

We investigate law enforcement within a population of norm- governed learning agents using a probabilistic rule-based argumentation framework. We show that this formal framework can advantageously complete a traditional analysis based on expected utilities for the study of law enforcement systems when more realistic assumptions than hyper-rational agents or some behavourial phenomenon such as inertia are desired. This has signicant implications for the design of systems of retributive justice for self-organising electronic institutions with endoge- nous resources, where the cost of monitoring and enforcement of laws and norms has to be taken into consideration.

This paper proposes to integrate an argumentation framework with techniques from Temporal Constraint Satisfaction. Temporal constraints are thus embedded into legal argumentation to account for temporal aspects of legal reasoning. Through the accommodation of temporal constraints, the validity of arguments and of their conclusions is made relative to the time-points when the applied norms are alive, according to the adopted temporal perspective. A fixed-point semantics and an associated dialogue game are given.

There is a gap between the legal text description in XML trends and the legal knowledge representation of the norms that from the text starts. This gap affects the effectiveness of the legal resources exploitation and the integrity of the legal knowledge on the Web. This paper presents a legal document model for managing the legal resources in integrated way and linking all the different levels of representation.

This chapter adds a further dimension to interdisciplinary research on Semantic Web and Web Services: ICT is undergoing a strong and constant regulatory phenomenon at national, European and international level and needs to be constantly monitored. This makes it possible to develop and use technologies in a law-abiding manner and to be aware of the legal position (rights and duties) of oneself and third parties. This chapter aims at offering an overview of the legal framework that supports people’s access to Web Services, according to the Semantic Web innovations. The basic aspects examined include: delegation, liability, privacy and e-identity. Finally, a specific section dedicated to e-business will give a dynamic approach to the analysis, so as to consent further developments on the other issues that Semantic Web implies.

This chapter introduces the reader with the specificity of the development of a particular type of legal ontology, that is ontology of copyright law. The process of the development of this ontology (ALIS IP Ontology) should be seen as a miniature guide for anyone who will pursuit a goal to create an ontology for any sphere of law. In this chapter the development of the copyright ontology is not addressed separately as such, but in vaster perspective, analyzing not only particular problems that the development of the legal ontology implies, but also looking at the ontology development issues in the light of the general relation that the law (and intellectual property law in particular) has with the IT domain.

The paper is partly based on research done for the EU-funded (IST-2004-2.4.9) project ALIS (Automated Legal Intelligent System) on Intellectual Property Law. We describe the development process of the ALIS Intellectual Property ontology from both a legal and technical perspective. We discuss the scope and the features of this IP ontology, the lessons learned, and the problems solved. This is done by comparing our ontology (the ALIS IP ontology) with the IPRonto ontology, which too is dedicated to IP. The paper also points out the benefits of both the ALIS system in general and the ALIS IP ontology in particular. Future development of ALIS will involve expanding its ontology to also include patent law and trademark law. Once these three legal ontologies are in place, they will be consolidated into a single ontology that will provide the framework for a general IP ontology.

This paper analyzes the representation of legal knowledge, and of Intellectual Property (or IP) law in particular. This is done by looking at two ways of representing the IP domain: through an IP ontology and by way of rule representation. And although these two solutions differ in many respects, they share the conceptual problems specific to this domain. This paper is based on research conducted under the EU-funded project ALIS (IST-2004-2.4.9).

CODE OF CONDUCT ,AGENT-BASED ARCHITECTURE ,STANDARD REGULATORY FRAMEWORK ,SOFTWARE AGENTS ,CONTRACT NEGOTIATION - Abstract
The objective of paper is to see how software agents can help carry out the contract-making activities (including pre-contractual negotiations and contract performance) involved in electronic commerce. One area in e-commerce where software agents can make a positive contribution is in virtual enterprises: they can do so by making business transactions more fluid in the digital environment. Another area is consumer protection, and this is the counterpart to the contribution made in facilitating business. The paper also gives examples of how agent-based architectures can be applied in industry and commerce, and indicates the main directions that researchers have taken in this field. The main lesson learnt in researching this paper is that it is indispensable to have a Code of Conduct to be adopted as a standard regulatory framework for the future.
