Exploring Semantic Hits
This event took place on Wednesday 06 May 2009 at 11:30

 
Thomas Ullmann KMi, The Open University

SemSearchXplorer is a toolkit for the exploration of semantic data. The goal is to lower barriers to access information in semantic data
repositories. Therefore SemSearchXplorer supports the user in three respects: (1) It supports querying of the semantic data with a keyword based approach, so the users do not need to learn a semantic query language, (2) it helps users finding relevant results on the one hand by semantic enriched information about the results and on the other hand with semantic filter options to narrow down the set of results, and (3) it provides information exploration capabilities through semantic visualizations recommended by the system. Filtering of semantic search results helps to narrow down the result set to a more manageable amount of information. SemSearchXplorer uses a class filter and a filter based on the key concepts of an ontology to support filtering of information. Besides the searching for relevant information, facilities for the exploration of the results help users to gain insight in the context of results. With several semantic visualizations, we try to help users making sense of the raw data. Based on the assumption that there is no single visualization that fit all exploration needs, SemSearchXplorer recommends visualizations based on the selected information of users.

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
