In collaborative ontology engineering, contexts are key to manage the complexity of different dependency types between ontological artefacts. Instead of being frustrated by out-of-control evolution processes, proper context dependency management will allow human experts to focus on the meaning interpretation and negotiation processes. This requires support for the detection and resolution of me...

This paper shows how partial equity participations can solve the hold-up problem: by weakening the bargaining position, they make the hold-up less effective, and thus improve investment and specialization incentives of the other party. With one-sided dependency, a 50% participation gives full efficiency. In the case of bilateral dependency, the unique efficient solution is equivalent to a merge...

In this paper, we show how HPSG, with some adjustments, can be seen as a particular implementation of a dependency grammar and we discuss the advantages of such a view and the resulting status of phrases. Our study focuses on extraction which is the cornerstone of the theory and one of the more problematic phenomena for our hypothesis, the interpretation of HPSG as a dependency grammar. Our ana...

This paper scrutinizes various dependency-based representations of the syntax of function words, such as prepositions. The focus is on the underlying formal object used to encode the linguistic analyses and its relation to the corresponding linguistic theory. The polygraph structure is introduced: it consists of a generalization of the concept of graph that allows edges to be vertices of other ...

This paper has two main objectives. The first is to provide an overview of the CDT annotation design with special emphasis on the modeling of the interface between syntactic and morphological structure. Against this background, the second objective is to explain the basic fundamentals of how CDT is marked-up with semantic relations in accordance with the dependency principles governing the anno...

Electronic government, so called e-government, has been broadly defined as the use of information and communication technology (ICT) to transform government by making it more accessible, effective, and accountable (infoDev & CDT, 2002). The Internet is indeed the most powerful and popular means of delivering e-government. Hence, Web sites have been employed as a platform for delivering a wide r...

Beginning in 1990, outsourcing became a key approach to manage IS/IT. The Gartner Group has estimated that the market for outsourced IS/IT services reached $280 billion in 2005, and would expand to $410 billion by 2007. However, there are considerable intractable and unforeseen risks in outsourced IS/IT projects (Taylor, 2006), and making decisions therein is complex and unpredictable. Much of ...

Dependency graph is an abstract mathematical structure for representing complex causal dependencies among its vertices. Several equivalence and model checking questions, boolean equation systems and other problems can be reduced to fixed-point computations on dependency graphs. We develop a novel distributed algorithm for computing such fixed points, prove its correctness and provide an efficie...

One of the problems encountered in Philosophy of Mind is that cognitive theories have a nontrivial dependence on the context of specific neurological makeups or mechanisms of individuals and species. Due to this context-dependency, for example, regularities or relationships between cognitive states are not considered genuine laws and cannot be directly related to neurological laws. The classica...
