Magpie - a framework for developing semantic web applications
This event took place on Monday 18 October 2004 at 12:30
Martin Dzbor KMi, The Open University
Magpie is a suite of tools both on client and server side that uses knowledge of a specific problem domain captured in a shared ontology, to semantically markup web documents on-the-fly. The user interacts with Magpie through a web browser plugin that visually annotates the concepts of interest in the web page the user visits. Concepts recognition depends on the selection of a particular ontology by the user. In addition to the ontology-driven annotation, Magpie allows users to invoke contextually specific semantic services for the annotated concepts and to subscribe to various trigger services that may use semantic knowledge acquired from the web page and ontology to notify user of interesting concepts or conclusions. Different concepts offer different sets of such services, and thus enabling the user to 'browse' the web semantically rather than through physically linked web pages.
The session will summarize what Magpie is about, who can benefit from tools like Magpie, and why it has been developed. There will be a basic functionality demonstration and a look at different perspectives of our research. I will demonstrate functionality of the Magpie framework using educational domain. This is a pilot application developed for the OU entry level course on climatology, jointly funded by climateprediction.net and AKT projects. It illustrates the role of supporting interpretation of web documents, as well as using semantic web infrastructure to develop richer applications.

Semantic Web and Knowledge Services is...
Our research in the Semantic Web area looks at the potentials of fusing together advances in a range of disciplines, and applying them in a systemic way to simplify the development of intelligent, knowledge-based web services and to facilitate human access and use of knowledge available on the web. For instance, we are exploring ways in which tnatural language interfaces can be used to facilitate access to data distributed over different repositories. We are also developing infrastructures to support rapid development and deployment of semantic web services, which can be used to create web applications on-the-fly. We are also investigating ways in which semantic technology can support learning on the web, through a combination of knowledge representation support, pedagogical theories and intelligent content aggregation mechanisms. Finally, we are also investigating the Semantic Web itself as a domain of analysis and performing large scale empirical studies to uncover data about the concrete epistemologies which can be found on the Semantic Web. This exciting new area of research gives us concrete insights on the different conceptualizations that are present on the Semantic Web by giving us the possibility to discover which are the most common viewpoints, which viewpoints are mutually inconsistent, to what extent different models agree or disagree, etc...
Our aim is to be at the forefront of both theoretical and practical developments on the Semantic Web not only by developing theories and models, but also by building concrete applications, for a variety of domains and user communities, including KMi and the Open University itself.
