A Pitch on Future Recommender Systems

Thursday, November 27th, 2008

Yesterday I attended a workshop that was aimed at fostering research collaboration between our department and BSkyB. After a short introduction by the head of the department, a number of members of staff gave short (10 minute) pitches about their past and current research, and areas they are interested in for potential collaboration. The range of work being done in the department is huge- perhaps this deserves a post of its own.


Context Matters

Friday, June 27th, 2008

The view we have of recommender systems is that of two-dimensional systems (users x items) whose main goal is to `recommend items to users’. However, as well illustrated in this paper, “decision making is contingent upon the context of decision making; the same consumer may [...] prefer different products or brands under different contexts”. For example, I (the user) may want to be recommended different restaurants (the item), depending on when I am going (the context), with whom I am going (the context, again), and for what purpose (the context, yet again).

IYOUIT: mobile service to share personal experiences on the go

Thursday, June 26th, 2008

Officially released today: “[...] IYOUIT allows for an instant automated sharing of personal experiences within communities online. [...] The cutting edge of IYOUIT is in how information about and around the mobile user is automatically collected, analyzed and enriched for an enhanced user experienced and extra value to Web2.0 services. [...] IYOUIT is based on its own framework of software components to host various services and data sources. Framework components, for instance, track the positions of users via GPS and cellular information and identify places of interest over time by learning form their past behavior. Sharing your life with IYOUIT is easy! In the same way that you can communicate experiences to others, IYOUIT provides you with an easy access to the whereabouts of your buddies, informs you about local weather conditions and uploads photos you take and sounds you record. And if you come across an interesting book (or other products), simply take a picture of the ISBN code or the product ID with your phone, and IYOUIT will fill in the blanks for instant exchange with your friends. IYOUIT also records scanned Bluetooth or WLAN beacons and aggregates all data mentioned before into a wealth of context information that you may share with others worldwide on the Web and on the mobile phone.”

Two great workshops at iTrust

Friday, February 8th, 2008

1) Security and Trust Management (STM).

Papers by April 2nd.
The intersection of security and the real world has prompted research in trust management. This research should ideally translate into proposals of solutions to traditional security issues. But, more often than not, it’s all proposals and few solutions. That is why STM focuses on how trust management may practically solve security issues and, in so doing, how it may enable new applications (eg, reputation, recommendation, collaboration in P2P or mobile nets). The call covers a wide range of topics.

2) Combining Context with Trust, Security, and Privacy (CAT). Paper abstracts by March 28th.
A research field might claim to have entered mainstream status only after it has been accepted by established conferences. Context-awareness and trust management have had that honour, but they have had it separately. We know by now how to design context-aware systems and trust management systems, but how to integrate the two is still the province of unexplored territory. That is why CAT will feature intrepid researchers who will stop us from:

  • sitting down in utter apathy towards the issue of trust being context-dependent – if (context=category of trust), as “rock music” is in “I trust you for recommending rock music”.
  • passing over exciting percom applications – if (context=space of interaction) as “my company premises” is in “my PDA is trusted for accessing confidential documents only within my company premises”.

Last year, CAT was terrific – I still remember the informing talks by Maddy, Tyrone and Linda. This year, it is likely to be even better. That is because CAT is like Math – one does context plus trust, and then multiplies by many researchers to equal stimulating discussion ;-)
