Graphical representation and similarity measurement of relevance judgments on the web

The purpose of this paper is to present a method for the graphical representation and similarity measurement of relevance judgments on the web. In order to address this objective a Latent Semantic Indexing technique was used. The findings suggest that the proposed method could help researchers in information seeking and retrieval to make methodological decisions about their data, such as the selection of specific subsets of relevance judgments for further examination, the recording of dissimilarities between judgments, or, the identification of possible cognitive shifts and abnormalities in relevance judgment behavior during web searching.
