Overview of the Wikipedia Image Retrieval Task at Imageclef 2011 - scientific work related to Wikipedia quality published in 2011, written by Theodora Tsikrika, Adrian Popescu and Jana Kludas.

Overview

ImageCLEF's Wikipedia Image Retrieval task provides a testbed for the system-oriented evaluation of multimedia and multilingual infor- mation retrieval from a collection of Wikipedia images. The aim is to in- vestigate retrieval approaches in the context of a large and heterogeneous collection of images (similar to those encountered on the Web) that are searched for by users with diverse information needs. This paper presents an overview of the resources, topics, and assessments of the Wikipedia Image Retrieval task at ImageCLEF 2011, summarizes the retrieval ap- proaches employed by the participating groups, and provides an analysis of the main evaluation results.
