dc.description.abstract | This paper introduces a new method for information retrieval of documents that are represented by a vector. The novelty of the algorithm lies in the fact that no (generalized) p-norms are used as a matching function between the query and the document (as is done e.g. by Salton and others) but a function that measures the relative dispersion of the terms between a document and a query. This function originates from an earlier paper of the author where a good measure of relative concentration was introduced, used in informetrics to measure the degree of specialization of a journal w.r.t. the entire subject. This new information retrieval algorithm is shown to have many desirable properties (in the sense of the new Cater-Kraft wish list) including those of the original cosine-matching function of Salton. In addition the property of the cosine-matching function that, if one only uses weights 0 to 1, one is reduced to Boolean IR, is refined in the sense that one takes into consideration the broadness or specialization of a document and a query. Our new matching function satisfies these additional properties. | - |
