Abstract

Data integration and mediation have become central concerns of information technology over the past few decades. With the advent of the Web and the rapid increases in the amount of data and the number of Web documents and users, researchers have focused on enhancing the interoperability of data through the development of metadata schemes. Other researchers have looked to the wealth of metadata generated by bookmarking sites on the Social Web. While several existing ontologies have capitalized on the semantics of metadata created by tagging activities, the Upper Tag Ontology (UTO) emphasizes the structure of tagging activities to facilitate modeling of tagging data and the integration of data from different bookmarking sites as well as the alignment of tagging ontologies. UTO is described and its utility in modeling, harvesting, integrating, searching, and analyzing data is demonstrated with metadata harvested from three major social tagging systems (Delicious, Flickr, and YouTube).

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 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.

Content

This paper presents a longitudinal case study and analysis of tagging patterns in del.icio.us. Previous research has indicated that a tagging vocabulary will stabilize over time, suggesting that convergence may occur. This case study investigates the possibility of stability and convergence in a subset of the tagging vocabulary used with del.icio.us.

Abstract

Research on categories indicates that superordinate categories lack informativeness because they are represented by only a few attributes while subordinate categories lack cognitive economy because they are represented by too many attributes (e.g., Rosch, Mervis, Gray, Johnson, & Boyes-Braem, 1976). Basic level categories balance informativeness and cognitive economy: They represent the most attributes common to category members and the fewest attributes shared across categories. Green (2006) has suggested that the universality of basic level categories can be used for building crosswalks between classificatory systems. However, studies of basic level categories in KO systems have assumed that the notion of a basic level category is understood and have failed to operationalize the notion of "basic level category" before applying it in the analysis of user-generated vocabularies. Heidegger's (1953/1996) notion of handiness (i.e., zuhandenheit, or being "at hand" can provide a framework for understanding the unstable and relational nature of basic level categories and for operationalizing basic level categories in KO research.

Abstract

This paper proposes to explore the nature of graphic language documents from the contrasting perspectives of structure and function -- from the perspectives of the document's structure as a spatially-oriented object. Using design principles derived from Gestalt theory and the Bauhaus concept that form (or structure) follows function, the paper addresses the relationship that exists between structure and function in the broad domain of graphic language documents

Abstract

The argument presented here seeks to extend the notion of the classification scheme as a culturally-transmitted tool by emphasizing the cognitive value of the scheme's internal patterns of relationship. lt elaborates an the use of classification as cognitive scaffolding (Jacob, 2001) and amplifies this idea through application of three constructs - constraints, selections and expectations - derived from Luhmann's (1995) theory of social systems.
