Title

Duality in information retrieval and the hypegeometric distribution

Source

Journal of documentation. 53(1997) no.5, S.499-496

Year

1997

Abstract

Asserts that duality is an important topic in informetrics, especially in connection with the classical informetric laws. Yet this concept is less studied in information retrieval. It deals with the unification or symmetry between queries and documents, search formulation versus indexing, and relevant versus retrieved documents. Elaborates these ideas and highlights the connection with the hypergeometric distribution
