"Information retrieval may be defined roughly as a procedure to either locate or physically retrieve a document or documents containing information on a given topic with a high degree of reliability. Information retrieval is one of the newest fields in computing science. Being so new there are many unexplored areas. The research that has been done has not been standardized beyond the point of the effort which has been slanted toward solving the "Library Problem" ... Several different information retrieval methods have been suggested and some research done on them to try and solve the "Library Problem". Of these methods only one is built around a complete mathematical model. This model is "Latent Class Analysis" ... The purpose of this study is to take this method ... and change the non-symmetric matrices to symmetric matrices to make a workable system still based on a sound mathematical model quite similar to the latent class model" – Introduction, p. 1-3.
