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...

legibility is one of the most important characteristics of good urban environments which improves the communication between people and place by helping them to perceive and recognize their environment more deeply and precisely. unfortunately, achieving legibility in today’s urban environments has become very hard due to the increase in incoherent developments and partial renovation projects. mo...

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...

Different semantic interpretation tasks such as text entailment and question answering require the classification of semantic relations between terms or entities within text. However, in most cases it is not possible to assign a direct semantic relation between entities/terms. This paper proposes an approach for composite semantic relation classification, extending the traditional semantic rela...

One of the main problems of the current Digital Libraries (DLs) is the limitation of the informative services offered to the users. Indeed, DLs provide simple search functionalities which return a list of the information objects contained in them. No semantic relation among the returned objects is usually reported which can help the user in obtaining a more complete knowledge on the subject of ...
