Abstract. The standardization of the second generation Web Ontology Language, OWL, leaves a crucial issue for Web-based ontologies unsatisfactorily resolved: how to represent and reason with multiple distinct, but linked, ontologies. OWL provides the owl:imports construct which, roughly, allows Web

The effects of neutrality on evolutionary search have been considered in a number of studies, the results of which, how-ever, have been contradictory. Some have found neutrality to be beneficial to aid evolution whereas others have argued that neutrality in the evolutionary process is useless. We

Abstract：Semantic not consistency, and knowledge base is difficult to reuse and sharing are the key problems affecting the system development and application. This paper studies how to express the soil fertility level information using of the ontology and generate OWL (Ontology Web Language

Syndication likely affects both of these performance drivers. 2 There are at least three reasons

novel algorithm that uses a divide and conquer strategy for parallelizing OWL TBox classification, a key reasoning task. We dis-cuss some interesting properties of our algorithm, for example, its suitability for distributed reasoning, and present an empirical study using a set of benchmark ontologies

This paper provides a survey to and a comparison of state-of-the-art Semantic Web reasoners that succeed in classifying large ontologies expressed in the tractable OWL 2 EL profile. Reasoners are characterized along several dimensions: The first dimension comprises underlying reasoning

networks. Using the semantics of the FOAF ontology and ap-plying Semantic Web reasoning techniques, we show that a significant percentage of profiles can be merged from multi-ple networks. We present results on how this affects network structure and what it says about the success of the Semantic Web.

effort has been invested in the study of transformational, charismatic, visionary, or inspiring leaders. In contrast to rational or "transactional" approaches to leadership, transformational and charismatic theories have been framed to recognize the affective and emotional needs and responses

morphology. Finally, I will present how, speci cally, information networks affect social structures (as conceptualized in this article) to induce the kind of transformations we are observing. Within the limits of tentative elaboration, this exercise intends to open the way for a theoretically meaningful codi

This paper reports a comparison of two separate studies using the same task and simulation software but with different age groups and abilities of students who have had different curricula experiences. One study examined how middle school students used computer simulation tools to reason between
