In heterogeneous multi agent systems, communication is hampered by the lack of shared ontologies. Ontology negotiation is a technique that enables pairs of agents to overcome these difficulties by exchanging parts of their ontologies. As a result of these micro level solutions, a communication vocabulary emerges on a macro level. The goal of this paper is to ensure that this communication vocab...

This paper is about the changing relationship between humanitarian aid and ‘politics’. Specifically, it is concerned to unpack the much touted calls for increased ‘coherence’ between political and humanitarian responses to complex emergencies. It argues that by sleight of hand, the coherence agenda has been reinterpreted such that humanitarian action has become the primary form of political act...

Oceania is a geographical, often geopolitical, region consisting of numerous states, mostly islands in the Pacific Ocean and vicinity. It generally includes Australia and New Zealand, and is often taken to include New Guinea and Pacific Islands. Though there have been a number of published studies evaluating vitamin D status in Australia and New Zealand, data from the rest of Oceania are lacking.

To meet the needs for large-scale, high-quality learning contents, needless to say, we have to sharpen authoring tools. Authoring process can be roughly divided into two phases, a composing phase and a verification phase. A great deal of effort has been made on the support in the former phase. What seems to be lacking, however, is that in the latter. An ontology-aware authoring tool we have bee...

The goal of the Ontology Summit 2010 was to address the current shortage of persons with ontology expertise by developing a strategy for the education of ontologists. To achieve this goal we studied how ontologists are currently trained, the requirements identified by organizations that hire ontologists, and developments that might impact the training of ontologists in the future. We developed ...

Ontology Summarization has been found useful to facilitate ontology engineering tasks in a number of different ways. Recently, it has been recognised as a means to facilitate ontology understanding and then support tasks like ontology reuse in ontology construction. Among the works in literature, not only distinctive methods are used to summarize ontology, also different measures are deployed t...

The Drosophila anatomy ontology (DAO) defines the broad anatomy of the fruitfly Drosophila melanogaster, a genetic model organism. It contains over 8700 classes, with close to half of these corresponding to neuroanatomical terms. We are systematically reviewing the DAO classes, improving the textual information and classification. This includes adding definitions, comments and synonyms, as well...

Ontology is traditionally conceived as the investigation of what there is or, a bit more precisely, the attempt to determine the most basic and general ways of being. This endeavor typically entails the project of articulating the fundamental kinds of beings, frequently with the aim of sorting them into a taxonomic order (where some kinds are superordinate or structure the others).1 The aim of ...

Understanding which ontology characteristics can predict a “good” quality ontology, is a core and ongoing task in the Semantic Web. In this paper, we provide our findings on which structural ontology characteristics are usually observed in high-quality ontologies. We obtain these findings through a taskbased evaluation, where the task is the assessment of the correctness of semantic relations. ...
