Retrieving Diverse Social Images 2013 Task
@ the MediaEval 2013 Multimedia Benchmark Evaluation
Call for Participation
Regular registration deadline: 1 May 2013

We are happy to announce the opening of the registration for the new
2013 Retrieving Diverse Social Images Task of the MediaEval Multimedia

**About the Retrieving Diverse Social Images 2013 Task**

The diversity task is a new task for 2013. The task addresses the
problem of result diversification in social photo retrieval.

We consider a tourist use case where a person tries to find more
information about a place she is potentially visiting. The person has
only a vague idea about the location, knowing the name of the place. She
uses the name to learn additional information about the monument from
the Internet, for instance by visiting a Wikipedia page, e.g., getting a
photo, the geographical position of the place and basic descriptions.
Before deciding whether this location suits her needs, the person is
interested in getting a more complete visual description of the place.

In this task, participants are provided with a ranked list of photos of
a location retrieved from common social photo search engines. These
results are typically noisy and redundant.

The task requires participants to exploit the provided visual and
textual information to refine these results by selecting only a sub-set
of photos.
The selected photos should be equally representative - accurate matches
of the query location, diverse - depicting the query location in a
complete manner (e.g., different views of a monument at different times
of the day/year and under different weather conditions, drawings,
sketches) and compact - select only very few results (e.g., 10-20 photos
per query that fit a typical page of search results).
