This file maps semantic classes and semantic types to the major concept, providing contextual meaning to both the term as well as
the words contained in the term.  This semantic meaning, when applied to the terms, is used as a filter during term file look-ups.

              DESCRIPTION:      This is a pointer to the Major Concept, linking the semantic classification with a concept.  Only
                                Major Concepts are semantically classified.   Synonyms and Lexical Variants adopt the semantic 
                                classification of the parent Major Concept.

                                #757.1 where the semantic classification of the Major Concept is located.  This index is used to
                                obtain all of the semantic classes and type to which a Major Concept belongs.  



757.1,1       SEMANTIC CLASS         0;2 POINTER TO SEMANTIC CLASS FILE (#757.11) (Required)

              LAST EDITED:      AUG 07, 1996 
              DESCRIPTION:      This is a pointer to the general semantic class defined in the Semantic Class file #757.11 to which
                                the Major Concept belongs.  An example of a semantic class is ORG for concepts in the general class
                                of Organisms.

                                ^LEX(757.1,"AMCC",MC,SC,IEN) - where MC is the Internal Entry Number in the Major Concept Map file
                                #757 of the Major Concept, SC is the mnemonic for the Semantic Class (i.e., ORG organism, PRO
                                procedures) to which the Major Concept belongs and IEN is the Internal Entry Nunber in the Semantic
                                Map file #757.1 where the Major Concept/Semantic Class combination is located.  This index is used
                                extensively for filtered searches based on semantic classes and types.  



757.1,2       SEMANTIC TYPE          0;3 POINTER TO SEMANTIC TYPE FILE (#757.12) (Required)

              LAST EDITED:      AUG 07, 1996 
              DESCRIPTION:      This is a pointer to the specific semantic type defined in the Semantic Types file #757.12 to which
                                the Major Concept belongs.  Using the general semantic class ORG (Organism), examples of specific
                                semantic types would be plants, alga, fungus, virus, rickettsia, bacterium, animal, intertebrate,
                                vertebrate, amphibian, bird, fish, reptile, mammal, human, and organism.
