The UCREL semantic analysis system (USAS) is a software tool for undertaking the automatic semantic analysis of English spoken and written data. This paper describes the software system, and the hierarchical semantic tag set containing 21 major discourse fields and 232 fine-grained semantic field tags. We discuss the manually constructed lexical resources on which the system relies, and the sev...

Semantic Web and Adaptive Hypermedia come from different backgrounds, but it turns out that actually, they can benefit from each other, and that their confluence can lead to synergistic effects. This encounter can influence several fields, among which an important one is Education. This paper presents an analysis of this encounter, first from a theoretical point of view, and then with the help ...

We propose an interdisciplinary approach to applying and evaluating semantic search in the e-discovery setting. By combining expertise from the fields of law and criminology with that of information retrieval and extraction, we move beyond “algorithm-centric” evaluation, towards evaluating the impact of semantic search in real search settings. We will approach this by collaboration in an interd...

In this paper we present an architectural overview of a search engine based on semantic web technologies to improve the search for learning resources. The use of search engines has contributed to the success of the Web. At present, many people use search engines to retrieve relevant information about a topic and students also use search engines to find learning resources. Keyword-based searches...

Computational drug repositioning leverages computational technology and high volume of biomedical data to identify new indications for existing drugs. Since it does not require costly experiments that have a high risk of failure, it has attracted increasing interest from diverse fields such as biomedical, pharmaceutical, and informatics areas. In this study, we used pharmacogenomics data genera...

The hit rate of basic Peer-to-Peer protocols can be increased by using semantic metadata to transform the network structure or construct an overlay network. These semantic protocols benefit from the observation that the pattern of the stored or queried documents depends on the fields of interest of the nodes in the network. However, the performance of such networks highly depends on boundary co...

Although the current computer-aided design (CAD) and computer network technologies have laid the foundation for the emerging fields of computer supported cooperative work (CSCW) in multidisciplinary design, the heterogeneity of multidisciplinary design knowledge representation is still a major obstacle to sharing and exchanging multidisciplinary design knowledge for multidisciplinary collaborat...

Over the years the World Wide Web has seen a major transformation with dynamic content and interactivity being delivered through Web 2.0 and provision of meaning to Web content through the Semantic Web. Web 2.0 has given rise to special methods of eLearning; we believe that interactive multimedia and semantic technologies applied together can further enable effective reuse of such applications ...

The goal of this study was to cast light on the existence of functional callosal channels for the interhemispheric transfer (IHT) of spatial and semantic information. To do so, we recorded event-related potentials in healthy humans while performing a primed odd-even discrimination task. Targets were visually presented numbers preceded by single-letter primes signaling the probable presentation ...

Nowadays, the need for systems interoperability in or across enterprises has become more and more ubiquitous. Many research works have been carried out in the fields of information exchange, transformation, discovery and reuse. One of the main challenges in these researches is to overcome the semantic heterogeneity between enterprise applications along the life cycle of a product. As a possible...
