Abstract:

Modifications are given for an algorithm that establishes equivalences between descriptions characterizing the content of documents that is applicable to sub-structures for some descriptors. A description consists of a set of descriptors descriptors may be elementary or complex, i.e., an ordered triple A,b,B where A and B are descriptors and b is a relation. A descriptor language is defined that consists of the set of descriptions and the set of equivalences. A new algorithm is introduced for obtaining equivalent descriptions that is based on obtaining a reduced set of equivalences for efficiency of retrieval from a large file. Impact of the use of complex descriptors is being studied. Author
