Eventos : MediaEval 2012 Multimedia Benchmark Evaluation: Call for Participation 

Call for Participation
MediaEval 2012 Multimedia Benchmark Evaluation
Please register by 31 May 2012
MediaEval is a multimedia benchmark evaluation that offers tasks promoting
research and innovation in areas related to human and social aspects of
multimedia. MediaEval 2012 focuses on aspects of multimedia including and
going beyond visual content, including speech, language, audio and social
factors. Participants carry out one or more of the tasks offered and submit
runs to be evaluated. They then write up their results and present them at
the MediaEval 2012 workshop.

For each task, participants receive a task definition, task data and
accompanying resources (dependent on task) such as shot boundaries,
keyframes, visual features, speech transcripts and social metadata. In
order to encourage participants to develop techniques that push forward the
state-of-the-art, a "required reading" list of papers will be provided for
each task. Participation is open to all interested research groups. Please
sign up via http://www.multimediaeval.org (regular sign up will remain open
until 31 May).

The following tasks are available to participants at MediaEval 2012:

Placing Task
This task involves automatically assigning geo-coordinates to Flickr videos
using one or more of: Flickr metadata, visual content, audio content,
social information (Data: Creative Commons Flickr data, predominantly
English language, extended from the 2011 data set.)

Social Event Detection Task
This task requires participants to discover events and detect media items
that are related to either a specific social event or an event-class of
interest. By social events we mean that the events are planned by people,
attended by people and that the social media are captured by people. (Data:
URLs of images and videos available on Flickr and other internet archives
together with metadata).

Spoken Web Search Task
This task involves searching FOR audio content WITHIN audio content USING
an audio content query. It is particularly interesting for speech
researchers in the area of spoken term detection. (Data: Audio from four
different Indian languages and four South African languages. Each of the
ca. 2000 data item is an 8 KHz audio file 4-30 secs in length.)

Tagging Task
Given a set of tags and a video collection, participants are required to
automatically assign the tags to each video based on a combination of
modalities, i.e., speech, metadata, audio and visual. (Data: Creative
Commons internet video, nearly exclusively English, extended from the 2011

Affect Task: Violent Scenes Detection
This task requires participants to deploy multimodal features to
automatically detect portions of movies containing violent material. Any
features automatically extracted from the video, including the subtitles,
can be used by participants. (Data: A set of ca. 18 Hollywood movies that
must be purchased by the participants.)

Visual Privacy Task
For this task, participants propose methods whereby human faces occurring
in digital imagery can be obscured so as to render them unrecognizable. An
optimal balance should be struck between obscuring identity and maintaining
the quality of the viewing experience from the user perspective. (Data:
about 100 high resolution video files of ca 1m30s each and containing one
or more persons in an indoor environment.)

Brave New Tasks
This year, MediaEval will also run three new tasks in the areas of social
media, spoken content search and hyperlinking, and music tagging. These
tasks are "by invitation only" and are not included in the general
registration form. In order to receive an invitation, please contact the
task organizers.

MediaEval 2012 Timeline (dates vary slightly from task to task, see the
individual task pages for the individual deadlines:

31 May: Last day for regular sign up

1 July: Latest day for test data release
ca. 10 September: Run submission deadline
28 September: Working notes papers due
4-5 October: MediaEval 2012 Workshop, Pisa, Italy*
*The workshop is timed so that it is possible to attend the 12th European
Conference on Computer Vision ECCV 2012 (http://eccv2012.unifi.it/), held
7-13 October in Firenze, Italy, in the same trip.
