The millions of web pages populating the internet seem to be unstructured and chaotic, but there are implicit semantic relations between them. In this paper we propose to make explicit the underlying semantic structure of the internet, by measuring joint keyword occurrences in web pages, around our notion of “Semantic Contexts”. As a result, we can draw a “map” of semantic clusters which can be...

Recommender Systems have become a significant area in the context of web personalization, given the large amount of available data. Ontologies can be widely taken advantage of in recommender systems, since they provide a means of classifying and discovering of new information about the items to recommend, about user profiles and even about their context. We have developed a semantically enhance...

In model-driven engineering (MDE), software development is centred around a formal description (model) of the proposed software system, and other software artifacts are derived directly from the model. We are investigating semantically configurable MDE, in which specifiers are able to configure the semantics of their models. The goal of this work is to provide a modelling environment that offer...

We are developing a semantic data framework for virtual observatories. A Virtual Observatory provides online location, retrieval, and analysis services to a variety of heterogeneous scientific data sources. We employ semantic technologies to integrate data and provide “intelligent” services such as ontology-enhanced search, analysis, and data visualization. Our specific initial deployments are ...

Abstract Manual co-speech gestures can facilitate language comprehension, but do they influence comprehension in simultaneous interpreters, and if so, is this modulated by interpreting (SI) and/or experience? In a picture-matching task, 24 professional interpreters translators were exposed to utterances accompanied semantically matching representational gestures, unrelated pragmatic or no while...
