Expert Finding - Academia vs. Practice
This event took place on Wednesday 09 January 2008 at 11:30

 
Thijs Westerveld Teezir search solutions

With the start of an enterprise search track at TREC in 2005, the search for topical expertise has recently received quite some attention in the academic world. The practical value of an expert finding system is evident. Connecting people to interact and share their knowledge is widely recognised as an important factor in the successful operation of an enterprise or organisation. In this talk I will start to outline the field of expert finding from these two perspectives. I will discuss the
set-up of expert finding task as organized by TREC's expert finding track as well as the practical usefulness of such systems. The second part of the talk will focus on previous work I did in the context of the TREC benchmarks. Typically, expert finding systems follow one of two approaches. Either they build profiles for candidate experts based on the documents associated to them and ranking the profiles, or they create a document ranking aggregate document scores into person scores based on the person-document associations. I will discuss an approach that is somehow in between these two approaches and produces two document rankings, one topic based and one person based. The correlation between topical document ranking and personal document ranking is taken as an indication of the person's expertise. Finally, I will highlight the differences between the academic evaluation of expert finding and the real life situations as we find them in practice.

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
