Preface The legal domain represents a primary candidate for web-based information distribution, exchange and management, as testified by the numerous e-government, e-justice and e-democracy initiatives worldwide. The last few years have seen a growing body of research and practice in the field of Artificial Intelligence and Law which addresses a range of(More)
This paper discusses the use of computational linguistic technology to extract definitions from a large corpus of German court decisions. We present a corpus-based survey of definition structures used in this kind of text. We then evaluate the results of a definition extraction system that uses patterns identified in this survey to extract from dependency(More)
This research explains the melt spinning of bicomponent fibers, consisting of a conductive polypropylene (PP) core and a piezoelectric sheath (polyvinylidene fluoride). Previously analyzed piezoelectric capabilities of polyvinylidene fluoride (PVDF) are to be exploited in sensor filaments. The PP compound contains a 10 wt % carbon nanotubes (CNTs) and 2 wt(More)
The potential of knowledge-based technological support for work in the legal domain has become widely recognized in recent time. This paper argues for an approach that is meant to complement existing work on top-level, statute-based ontologies for the law by extracting conceptual knowledge from verdict texts. Starting from a corpus-based survey on the(More)
Complexity of hardware/software systems is continuously increasing. Formal specification is a methodology to ensure better quality of system specifications and to allow automated verification with tools like model checkers. Many formal specification approaches are known - ranging from programming languages to graphical specification tools. Each approach has(More)
