KMi Seminars
Beyond searching and browsing
This event took place on Thursday 17 March 2005 at 12:30

 
Tom Heath KMi, The Open University

The web provides a platform for users to perform many varied tasks; finding information, exploring new ideas, and communicating with others are just a few examples. However, not all tasks that users perform (or wish to perform) on the web are well supported by current tools and technologies. Interaction with web resources tends to be dominated by searching and browsing, and attempts to understand user actions on the web have focused mainly on these modes. Furthermore, the tools that support these modes, such as web browsers and search engines often take little account of the user, and the contexts in which they exist.

In this seminar I will briefly introduce scenarios of tasks performed online using current tools. These scenarios will be considered in the light of existing taxonomies of online actions, and I will introduce a new classification of the tasks people perform on the web. A case will be made that tools should take greater account of a user?s context if they are to aid task performance, and I will outline my proposals for task-focused Semantic Web tools that draw on a user?s social context.

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
