Duality in Information Retrieval and the Hypergeometric Distribution.
Rousseau, Ronald; Egghe, Leo
Journal of Documentation, v53 n5 p488-96 Dec 1997
Duality is an important topic in informetrics, often less studied in information retrieval where it relates to the unification or symmetry of queries and documents, search formulation versus indexing, and relevant versus retrieved documents. This article examines duality in information retrieval and highlights its connection with hypergeometric distribution. (PEN)
