Some Experiments on the Wikipediamm 2008 Task: Evaluating the Impact of Image Names in Context-Based Retrieval - scientific work related to Wikipedia quality published in 2008, written by Mouna Torjmen, Karen Pinel-Sauvagnat and Mohand Boughanem.
Overview
The goal of participation in the WikipediaMM task of CLEF 2008 was to study the use of the name of images in a context-based retrieval approach. Authors evaluated this factor in three manners. The first one consists of using image names explicitly: authors computed a similarity score between the query and the name of images using the vector space model. The second one consists of combining results obtained using the textual content of documents and results obtained using the first method. Finally, in last approach, image names are used less explicitly. Authors proposed to use all the textual content of documents, but authors increased the weight of terms in the image name. Results show that the ”image name” is an intersting factor. Even if the image names are used as an additional source of evidence, they allow to better performance. Moreover, authors conclude thet using the image name implicitly performs better results than using it explicitly.
