       *** Call for participation: wikipediaMM image retrieval 2009 ***

ImageCLEF's wikipediaMM  is an ad hoc image retrieval task that provides a
testbed for the system-oriented evaluation of visual information retrieval
from a collection of 150,000 Wikipedia images which are associated with
unstructured and noisy textual annotations in English. The aim is to
investigate multimodal retrieval approaches in the context of a large and
heterogeneous collection of images (similar to those encountered on the
Web) searched by users with diverse information needs.

The main aim is to investigate:
    * how well do the retrieval approaches cope with larger scale image
collections?
    * how well do the retrieval approaches cope with noisy and
unstructured textual annotations?
    * how well do the content-based retrieval approaches cope with images
that cover diverse topics and are of varying quality?
    * how well can systems exploit and combine different modalities given
a user's multimedia information need?

The main focus in 2009 is to investigate the combination of evidence of
relevance derived from different modalities, through the fusion of visual,
text-based, and concept-based sources of evidence. To support participants
with expertise in diverse research domains, we aim at providing baseline
monomedia retrieval systems.
