ActiveMath is a complex Web-based adaptive learning environment with a number of components and interactive learning tools. The basis for handling semantics of learning content is provided by its semantic (mathematics) content markup which is additionally annotated with educational metadata. Several components, tools, and external services can make use of that content markup, for instance a cou...

This paper examines the question of differences between a traditional interlingua approach and a transferbased approach that uses cross-linguistic semantic features to generalize its transfer lexicon entries, and concludes that the two approaches share a common interest in lexical classifications that can be distinguished by cross-linguistic semantic features. The paper goes on to discuss curre...

We posit that a robust development environment for the construction of agent-oriented software systems must be enhanced by advanced reuse methods. However, research addressing agent reuse is meager and does not tackle the problem of organizing and storing agent-oriented artifacts according to the software engineers’ needs. Therefore, the agent retrieval process turns into an important challenge...

The increasing reliance on information gathered from the web and other internet technologies raise the issue of trust. Through the development of semantic Web, One major difficulty is that, by its very nature, the semantic web is a large, uncensored system to which anyone may contribute. This raises the question of how much credence to give each resource. Each user knows the trustworthiness of ...

Current models for software components have made component-based software engineering practical. However, these models are limited in the sense that their support for the specification of software components primarily deals with syntactic issues. To facilitate interoperability and proper use of software components, more comprehensive specification of these components is required. In this paper,...

The creation of hypervideos—displayed video streams that contain embedded user-clickable anchors and annotations—is a manual and tedious job, requiring the preparation of assets like still frames, the segmentation of videos in scenes or chapters, and sometimes even the isolation of objects like faces within the video. In this paper, we propose a semi-automated Web-Components-based approach to s...

Semantic cognition, which encompasses all conceptually based behavior, is dependent on the successful interaction of two key components: conceptual representations and regulatory control. Qualitatively distinct disorders of semantic knowledge follow damage to the different parts of this system. Previous studies have shown that patients with multimodal semantic impairment following CVA--a condit...
