Bell Communications Research, James W Falk, John T Peoples, June 13, 1989: US04839853 (412 worldwide citation)

A methodology for retrieving textual data objects is disclosed. The information is treated in the statistical domain by presuming that there is an underlying, latent semantic structure in the usage of words in the data objects. Estimates to this latent structure are utilized to represent and retriev ...
