Btu Dbis' Multimodal Wikipedia Retrieval Runs at Imageclef 2011 - scientific work related to Wikipedia quality published in 2011, written by David Zellhöfer and Thomas Böttcher.

Overview

In this work, authors summarize the results of first participation in the Wikipedia Retrieval task. For experiments, authors rely on a cognitively motivated IR model: the principle of polyrepresentation. The principle’s core hypothesis is that a document is defined by different representations such as low-level features, or textual content that can be combined in a structured manner reflecting the user’s information need. For first participation, authors used mono-lingual English retrieval in combination with global low-level features without further user interaction or query modification techniques. Authors best NOFB reached rank 64 or rank 13 of the mono-lingual English runs. This result is promising as authors have not used structural information about the documents. Additionally, findings are indicating the correctness of the polyrepresentative hypothesis for multimodal retrieval.
