The author explores inter‐record linkage relationships of a bibliographic hypertext system through the use of descriptor term co‐occurrences. Using term distribution and term exhaustivity data for an existing system, three models of term co‐occurrence are developed and tested against the observed data. The observed distribution of term co‐occurrences using term sizes follows a complex, but regular relationship. The developed models, although matching the observed behavior for much of the distribution, do not adequately model the observed co‐occurrence patterns for select parts of the distribution using chi‐square values. With knowledge of the structure of such a hypertext system, an appropriate model may be constructed and used as the basis for studying systems design of inter‐record linkages and system navigation by users in such a hypertext system. © 1996 John Wiley & Sons, Inc.
