Special purpose computers for information retrieval

World Patent Information, 1983, vol. 5, issue 4, 230-232

Abstract: This article reviews patent publications in the field of database processors for information retrieval. Emphasis is laid on associative processors, i.e. processors which reference data by content rather than by memory position or location. High speed is obtained by parallel manipulation of data from many channels of multiple head discs, magnetic bubble or other static memory devices. Very large databases use a combination of such a system and a directory system, i.e. a system comprising in addition to the main file other files containing a dictionary and pointers to the main file. Because of the importance of the associative memories, a survey thereof is also given.
