Semantic Search Components
This event took place on Wednesday 08 November 2006 at 11:30

Dr. Victoria Uren KMi, The Open University, UK

Formulating complex queries is hard, especially in heterogeneous information environments, where users do not understand all the data structures of multiple complex knowledge bases. We see a gap between semantic search tools that are user friendly, but have restricted functionality, and powerful, formal query languages, which are unsuitable for end users. We explore the complexity of semantic queries through an example. Building on this example, we propose a solution using a component based approach. We propose a layered architecture, with components taking an intermediary role between the end user interface and formal query languages. The kinds of components that would be needed for such a system are outlined, and challenges for the system are discussed, in particular, how to combine semantic searches. This paper was presented at EKAW 2006.

Future Internet is...


Future Internet
With over a billion users, today's Internet is arguably the most successful human artifact ever created. The Internet's physical infrastructure, software, and content now play an integral part of the lives of everyone on the planet, whether they interact with it directly or not. Now nearing its fifth decade, the Internet has shown remarkable resilience and flexibility in the face of ever increasing numbers of users, data volume, and changing usage patterns, but faces growing challenges in meetings the needs of our knowledge society. Globally, many major initiatives are underway to address the need for more scientific research, physical infrastructure investment, better education, and better utilisation of the Internet. Within Japan, USA and Europe major new initiatives have begun in the area.

To succeed the Future Internet will need to address a number of cross-cutting challenges including:

  • Scalability in the face of peer-to-peer traffic, decentralisation, and increased openness

  • Trust when government, medical, financial, personal data are increasingly trusted to the cloud, and middleware will increasingly use dynamic service selection

  • Interoperability of semantic data and metadata, and of services which will be dynamically orchestrated

  • Pervasive usability for users of mobile devices, different languages, cultures and physical abilities

  • Mobility for users who expect a seamless experience across spaces, devices, and velocities
