Some Temporal Aspects of Indexing and Classification: Toward a Metrics for Measuring Scheme Change. iConference 2012, February 7-10, 2012, Toronto, ON, Canada. ACM 978-1-4503-0782-6/12/02.http://hdl.handle.net/1773/37961In this paper we discuss the temporal aspects of indexing and classification in information systems. Basing this discussion off of the three sources of research of scheme change: of indexing: (1) analytical research on the types of scheme change and (2) empirical data on scheme change in systems and (3) evidence of cataloguer decision-making in the context of scheme change. From this general discussion we propose two constructs along which we might craft metrics to measure scheme change: collocative integrity and semantic gravity. The paper closes with a discussion of these constructs.pdfArticle
