A COMPARISON OF SOME MACHINE-PRODUCED INDEXES. TECHNICAL REPORT.
ADAMS, WILLIAM MANSFIELD
SOME MACHINE-PRODUCED INDEXES ARE COMPARED TO ASSIST IN DECIDING ON THE FORMAT FOR A PROPOSED INDEX. THE OBJECTIVES OF AN INDEX AND THE SEARCH PROCEDURE ARE ANALYZED, AND AN EXPLANATION AND A RELATIONSHIP IS GIVEN FOR KEY-WORDS-IN-TITLE AND KEY-REFERENCES OF THE SAME ARTICLE. BASED ON THE COMPARISON OF THE INDEXES, A 53- YEAR CUMULATIVE INDEX WAS CREATED FOR THE "BULLETIN OF THE SEISMOLOGICAL SOCIETY OF AMERICA." TYPICAL PAGES ARE SHOWN IN A KEYWORD AND AN AUTHOR (OR BIBLIOGRAPHY) INDEX. AN OPERATIONAL DEFINITION FOR RELEVANCE HAS BEEN GIVEN IN TERMS OF THE CONCEPTS IN THE POSED QUESTION INCLUDED IN THE TITLE OF THE DOCUMENT. USE OF A HYPOTHETICAL TITLE FOR SEARCHING A LIST OF TITLES PERMITS COMPARISON OF SIMILAR ITEMS FOR COMMON CHARACTERISTICS. A PROOF IS CITED THAT RELATES THE REFERENCES TO THE CONCEPTS COVERED BY AN ARTICLE. THE RELATION OF KEY REFERENCES TO KEYWORDS IS THEN EMPIRICALLY ESTIMATED BY ASCERTAINING THE KEY WORD-CONCEPT RELATIONSHIP. THIS DOCUMENT IS AVAILABLE AS PB-170-738 FROM THE CLEARINGHOUSE FOR FEDERAL SCIENTIFIC AND TECHNICAL INFORMATION, SPRINGFIELD, VIRGINIA 22151, $3.00 FOR HARD COPY, $0.65 FOR MICROFICHE, 49 PAGES.
