Abstract

A classification scheme is more predictable-and, thus, more effective-if it has a consistent structure. In this paper, a number of (defeasible) consistency rules for constructing classification schemes are identified (e.g., division by a single type of attribute, division at a single level of abstraction, horizontal consistency, vertical consistency). An explicit statement of these rules, not all of which have been explicitly codified in the library and information science literature, should be useful to the developers of retrieval systems. In addition, some preliminary suggestions are made regarding how these rules might be used to define a measure of the consistency of a classification scheme
