Introduction: The collaborative learning and interactive electronic-learning (e- learning) is one of the key factors in education system success. This study examined the collaborative e-learning in the framework of constructivism theory. Methods: This is a review article. The databases such as Scientific Information Databases, Magiran, Science Direct, and Google Scholar were reviewed. Also,...

The number of bio-ontologies is growing rapidly, indicating their important role in bioinformatics. But lacking is support for their curation – in particular for version management and quality control. Tools for ontology management are required in order to deal with the continuous process of ontology revision – no bio-ontology that is in active use remains unchanged after publication. MeSH is r...

To a large degree information and services for chemical eScience have become accessible -anytime, anywhere -but not necessarily useful. The Rule Responder eScience middleware is about providing information consumers with rule-based agents to transform existing information into relevant information of practical consequences, hence providing control to the end-users to express in a declarative ru...

Grid computing offers heterogeneous and distributed resources to scientific communities. Apparently, networks connecting these resources can also be considered as Grid resources. This paper presents ARGON, a system that integrates metro and wide area networks into Grid environments by providing advance reservations and guaranteed network services. Here, single-domain as well as multidomain netw...

Digital preservation research has increasingly been shifting focus from the preservation of data and static objects to investigate the preservation of complete processes and workflows. Capturing all aspects of a process to be preserved, however, is an extensive and difficult undertaking, as it requires capturing complete software setups with potentially complex setups. Further, the process migh...

The objective of this article is to examine how the inequalities of participation in network society governmental systems affect the extent that individuals are empowered or disempowered within those systems. By using published data in conjunction with theories of communication, a critical secondary data analysis was conducted. This critical analysis argues that the Digital Divide involves issu...

The information expressed in humanistic datasets is inextricably tied to a wider discursive environment that is irreducible to complete formal representation. Humanities scholars must wrestle with this fact when they attempt to publish or consume structured data. The practice of “nanopublication”, which originated in the e-science domain, offers a way to maintain the connection between formal r...

Ontologies have become central components in many applications including search, e-commerce, configuration and, arguably, every large web site (at least for organization and navigation). As ontologies become larger, more distributed, and longer-lived, the need for ontology creation and maintenance environments grows. In our work with ontologies and tool environments over the last few years, we ...

The paper builds on the initial investigations in the Business Data Integration Framework for the Small-to-Medium Enterprise (BDIFS) project into using Grid Services to build dynamic eBusiness integration environments. The concept of sharing user-driven translation mappings in dynamic grid service environments is introduced. These translations provide the mapping between the source and target s...

Logic-Based Argumentation (LBA) exhibits unique properties and advantages over other kinds of argumentation procedures, amongst them: the adequacy to logic-based pre-argument reasoning, similarity to the human reasoning process, reasoning with incomplete information and argument composition and extension. Logic enables a formal speci cation to be built and a quick prototype to be developed. In ...
