چکیده
Relevance has become a major area of research in the ®eld of Information Retrieval, despite the fact that the concept relevance is not well understood. This paper models manifestations of relevance within a system of relevance attributes to show that the attributes function in dierent dimensions for the dierent manifestations of relevance. It is shown that motivational relevance, as a manifestation of relevance, should not be viewed as part of a linear, objective±subjective scale of relevances, but rather as an attribute of relevance. Similarly, that the manifestation of aective relevance should not be viewed as a discrete category of relevance manifestation, but rather as an in ̄uencing factor on the other subjective relevance types. The paper argues a consolidated model of relevance manifestations which includes the notion of socio-cognitive relevance. 7 2000 Elsevier Science Ltd. All rights reserved.

We investigate the application of a novel relevance ranking technique, cover density ranking, to the requirements of Web-based information retrieval, where a typical query consists of a few search terms and a typical result consists of a page indicating several potentially relevant documents. Traditional ranking methods for information retrieval, based on term and inverse document frequencies, ...
