Abstract

One major aspect of T.D. Wilson's research has been his insistence on situating the investigation of information behaviour within the context of its occurrence - within the everyday world of work. The significance of this approach is reviewed in light of the notion of embodied cognition that characterises the evolving theoretical episteme in cognitive science research. Embodied cognition employs complex external props such as stigmergic structures and cognitive scaffoldings to reduce the cognitive burden on the individual and to augment human problem-solving activities. The cognitive function of the classification scheme is described as exemplifying both stigmergic structures and cognitive scaffoldings. Two different but complementary approaches to the investigation of situated cognition are presented: cognition-as-scaffolding and cognition-as-infrastructure. Classification-as-scaffolding views the classification scheme as a knowledge storage device supporting and promoting cognitive economy. Classification-as-infrastructure views the classification system as a social convention that, when integrated with technological structures and organisational practices, supports knowledge management work. Both approaches are shown to build upon and extend Wilson's contention that research is most productive when it attends to the social and organisational contexts of cognitive activity by focusing on the everyday world of work.

Abstract

This paper introduces the Just-in-Time Teaching (JiTT) digital library and describes the pedagogical nature of the resources that make up this library for educators. Because resources in this library are stored in the form of metadata records, the utility of the metadata scheme, its elements and its relationships is central to the ability of the library to address the pedagogical needs of instructors in the work domain of the classroom. The analytic framework provided by cognitive work analysis (CWA) is proposed as an innovative approach for evaluating the effectiveness of the JiTT metadata scheme. CWA is also discussed as an approach to assessing the ability of this extensive networked library to create a common digital environment that fosters cooperation and collaboration among instructors.

Abstract

This paper describes work in progress to identify automated methods to complement and streamline the intellectual process in the generation of faceted schemes. It reports on the development of the word pair heuristic, the suffix heuristic, and the WordNet heuristic, and how the three heuristics integrate to produce an initial organization of terms from which a classificationist can more efficiently construct a faceted vocabulary.

This paper outlines a formal and systematic approach to explication of the role of structure in information organization. It presents a preliminary set of constructs that are useful for understanding the similarities and differences that obtain across information organization systems. This work seeks to provide necessary groundwork for development of a theory of structure that can serve as a lens through which to observe patterns across systems of information organization.
