Current research in developing negotiation support systems focuses upon argumentation, artificial intelligence and game theory. These techniques are rarely used in tandem. We argue that truly intelligent negotiation support systems require the integration of such techniques. We integrate the argumentation techniques of Lodder and the combined artificial(More)
When procedural-support systems are to be useful in practice, they should provide support for causal reasoning about evidence. Such support should be both rationally well-founded and natural to the users of such systems. This article studies two possible foundations for such support, logics for defeasible argumentation and logical models of causal-abductive(More)
Much work on legal knowledge systems treats legal reasoning as arguments that lead from a description of the law and the facts of a case, to the legal conclusion for the case. The reasoning steps of the inference engine parallel the logical steps by means of which the legal conclusion is derived from the factual and legal premises. In short, the relation(More)
In all ODR-procedures, Information Technology (IT) is used. Artificial Intelligence (AI) applications are a subset of IT applications and add benefit either by using 'intelligent techniques' or by 'simply' performing in an intelligent way. In this paper the (possible) use of AI in ODR is addressed. Two negotiation systems, SmartSettle and Family_Winner, are(More)
In the context of intelligent disclosure of case law, we report on our findings on methods for retrieving relevant case law within the domain of tort law from a repository of 68.000 court verdicts. We apply a thesaurus-based technique to find specific legal situations. It appears that statistical measures of term relevance are not sufficient, but that(More)
In recent years, impressive progress has been made in the development of logical tools for the modeling of legal argument. The focus has been primarily on the technical development of these tools, and only in the second place on their practical adequacy for modeling legal argument. Presently a convergence of opinions on the necessary logical tools takes(More)
This paper describes the experiments carried out in the context of the BEST-project, an interdisciplinary project with researchers from the Law faculty and the AI department of the VU University Amsterdam. The aim of the project is to provide laymen with information about their legal position in a liability case, based on retrieved case law. The process(More)
This paper deals with a simple tool that we have developed to support the parties in online dispute resolution (ODR). The tool helps the participants to bring forward the statements of the dispute in a structured and concise way. After each added statement the online tool shows the structured layout of the statements. As an example, the tool has been(More)
