Second Contextual Suggestion Track

Text REtrieval Conference (TREC 2013)

November 19 - 22, Gaithersburg MD, USA

Submissions Due: July 15, 2013

* Call for Participants

The Contextual Suggestion track considers a complex information need, 
highly dependent on context, which nonetheless can be simply expressed. 
  The 2012 and 2013 tracks focus on one situation: a user with a mobile 
device with limited interaction but some sort of user profile; who is in 
a strange town; and who is looking for something to do.  There is no 
explicit query: the implicit query is “here I am, what should I do?”.

As input to the task, participants will be given a set of profiles, a 
set of geographical contexts, and a set of example suggestions.  Each 
profile corresponds to a single user, and indicates that user’s 
preference with respect to each example suggestion.  Each context 
corresponds to a particular city, for example, Gaithersburg, Maryland. 
Each example suggestion includes a title, description, and an associated 
URL.  One example suggestion might be to have a beer at the Dogfish Head 
Alehouse, and the profile might include a negative preference with 
respect to that suggestion.

For each profile/context pairing, participants should return a ranked 
list of up to 50 ranked suggestions. Each suggestion should be 
appropriate to the profile (based on the user’s preferences) and the 
context (according to the location).  The description of the suggestion 
may be tailored to reflect the preferences of that user.  Profiles 
correspond to the stated preferences of real individuals, who will 
return to judge proposed suggestions.  For the purposes of this 
experiment, you can assume users are of legal drinking age at the 
location specified by the context, has up to five hours available to 
follow a suggestion, and has access to appropriate transportation (e.g., 
a car).

The 2013 track covers several aspects:

- Filtering of suggestions based on context.
- Ranking of suggestions based on profiles.
- Personalization of suggestion descriptions.
