This paper addresses the problem of e cient management of events, in particular in those environments where events carry information useful to multiple applications, possibly operating in di erent domains and at di erent levels of abstraction. We investigate the problems and opportunities o ered by such environments, and de ne a framework that enables a semantic mapping of events, i.e., enables...

Masters, Mori, & Mori (1993) discuss the use of semantic mapping strategy. They define semantic mapping technique as being "used to motivate and involve students in the thinking, reading, and writing aspects. It enhances vocabulary development by helping students link new information with previous experience." The instructional sequence of semantic mapping is as follows: 1. Select a word centra...

To survive in the twenty-first century, enterprises need to collaborate. Collaboration at the enterprise-level presupposes the interoperability of the underlying information systems. Access to heterogeneous information sources must be provided transparently while maintaining their autonomy. Further, the availability of nearly unlimited information calls for efficient and precise information ret...

Selecting appropriate learning services for a learner from a large number of heterogeneous knowledge sources is a complex and challenging task. This article illustrates and discusses how Semantic Web technologies such as RDF and ontology can be applied to e-learning systems to help the learner in selecting an appropriate learning course or retrieving relevant information. It presents the main f...

Contrary to existing heterogeneous data integration systems which need to be fully integrated before using, a Dataspace Support Platform is a self-sustained system which automatically provides for the user its best endeavor results regardless of how integrated its sources are. Therefore, a Dataspace Support Platform needs to support uncertainty in mediated schema and in schema mappings. This pa...

This paper discusses some of the challenges in building a robot that is supposed to autonomously navigate in an urban environment by asking pedestrians for route directions. We present a novel Wizard-of-Oz setup for collecting route direction dialogues, and a novel approach for datadriven semantic interpretation of route descriptions into route graphs. The results indicate that it is indeed pos...

This project report details work carried out in collaboration between the University of Southampton and the Korea Institute of Science and Technology Information, focussing on an RDF dataset of academic authors and publications. Activities included the conversion of the dataset to produce Linked Data, the identification of co-references in and between datasets, and the development of an ontolog...

This work describes the architecture of Contorsion, a semantic XPath processor that acts over an RDF mapping of XML. It contributes to a recent research trend that defines an XML-to-RDF mapping allowing XML documents interoperate at the semantic level. We use a model-mapping approach to represent instances of XML and XML Schema in RDF. This representation retains the node order, in contrast wit...
