The Reason That Search Engines Are Fast But Not Very Accurate
This event took place on Wednesday 14 July 2010 at 11:30

 
Andrew Trotman University of Otago (New Zealand)

Search Engine Efficiency has been an active field of Information Retrieval research for many years and the literature is vast. When implementing a search engine it is necessary to wade through this literature and to make engineering decisions on what to implement and what to not. Andrew has recently implemented an new efficient search engine and in this presentation will outline its design. This search engine is fast and accurate, but as he will show; academically accurate. Unfortunately, it's not quite so obvious what academic accuracy means for a user.

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
