    Abstract
    Previous studies of user-generated vocabularies (e.g., Golder & Huberman, 2006; Munk & Mork, 2007b; Yoon, 2009) have proposed that a primary source of tag agreement across users is due to wide-spread use of tags at the basic level of abstraction. However, an investigation of levels of abstraction in user-generated tagging vocabularies did not support this notion. This study analyzed approximately 8000 tags generated by 40 subjects. Analysis of 7617 tags assigned to 36 online resources representing four content categories (TOOL, FRUIT, CLOTHING, VEHICLE) and three resource genres (news article, blog, ecommerce) did not find statistically significant preferences in the assignment of tags at the superordinate, subordinate or basic levels of abstraction. Within the framework of Heidegger's (1953/1996) notion of handiness , observed variations in the preferred level of abstraction are both natural and phenomenological in that perception and understanding -- and thus the meaning of "things" -- arise out of the individual's contextualized experiences of engaging with objects. Operationalization of superordinate, subordinate and basic levels of abstraction using Heidegger's notion of handiness may be able to account for differences in the everyday experiences and activities of taggers, thereby leading to a better understanding of user-generated tagging vocabularies.

    Abstract
    Argues that Beghtol's (2003) use of the terms "naive classification" and "professional classification" is valid because they are nominal definitions and that the distinction between these two types of classification points up the need for researchers in knowledge organization to broaden their scope beyond traditional classification systems intended for information retrieval. Argues that work by Beghtol (2003), Kwasnik (1999) and Bailey (1994) offer direction for the development of a classification of classifications based on the pragmatic dimensions of extant classification systems.

    Abstract
    LIS genre studies have suggested that representing the genre of a resource could provide better knowledge representation, organization and retrieval (e.g., Andersen, 2008; Crowston & Kwasnik, 2003). Beghtol (2001) argues that genre analysis could be a useful tool for creating a "framework of analysis for a domain ... [to] structure and interpret texts, events, ideas, decisions, explanations and every other human activity in that domain" (p. 19). Although some studies of user-generated tagging vocabularies have found a preponderance of content-related tags (e.g., Munk & Mork, 2007), Lamere's (2008) study of the most frequently applied tags at Last.fm found that tags representing musical genres were favored by taggers. Studies of user-generated genre tags suggest that, unlike traditional indexing, which generally assigns a single genre, users' assignments of genre-related tags provide better representation of the fuzziness at the boundaries of genre categories (Inskip, 2009). In this way, user-generated genre tags are more in line with Bakhtin's (Bakhtin & Medvedev, 1928/1985) conceptualization of genre as an "aggregate of the means for seeing and conceptualizin reality" (p. 137). For Bakhtin (1986), genres are kinds of practice characterized by their "addressivity" (p. 95): Different genres correspond to different "conceptions of the addressee" and are "determined by that area of human activity and everyday life to which the given utterance is related" (p.95). Miller (1984) argues that genre refers to a "conventional category of discourse based in large-scale typification of rhetorical action; as action, it acquires meaning from situation and from the social context in which that situation arose" (p. 163). Genre is part of a social context that produces, reproduces, modifies and ultimately represents a particular text, but how to reunite genre and situation (or text and context) in systems of knowledge organization has not been addressed. Based on Devitt's (1993) argument suggesting that "our construction of genre is what helps us to construct a situation" (p. 577), one way to represent genre as "typified rhetorical actions based in recurrent situations" (Miller, 1984, p. 159) would be to employ genre tags generated by a particular group or community of users. This study suggests application of social network analysis to detect communities (Newman, 2006) of genre taggers and argues that communities of genre taggers can better define the nature and constitution of a discourse community while simultaneously shedding light on multifaceted representations of the resource genres.

    Abstract
    In information science, classification systems are conventionally viewed as tools for representing knowledge in the universe of ideas, the human mind, or one or more sets of documents. In this view, developing and maintaining relationships and structures in classification schemes must primarily consider two abstract ingredients: i) a set of concepts for one or more domains; and ii) a (set of) unambiguous structure(s) to articulate the relationships that persist between the various concepts that comprise the classificatory structure. We contend that design decisions pertaining to the structure of a classification system consist of far more than simply creating links between the elements in a particular set of concepts. Ultimately, a simplistic tool view of classifications implies that the construction is little more than a technical task in a very narrow sense: that classificatory concepts are viewed as standard representations of what are assumed to be the central and/or important topics in the knowledge domain(s), and that there is i) an unambiguous Platonic ideal or universal consensus that determines how the links will be generated within a classificatory structure; or, conversely, ii) that there are no general structures and relationships available at all, but that only diverse individual knowledge structures exist, which cannot be reconciled into a general organization of knowledge

    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
    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
    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
    Studies of user-generated tagging vocabularies (e.g., Yoon 2009) suggest that tag agreement across users is due to wide-spread use of basic level category terms. This study investigated whether differences in the superordinate, subordinate or basic level of abstraction were influenced by resource content. Analysis of 7617 tags assigned by 40 participants to 36 online resources representing four content categories (i.e., TOOL, FRUIT, CLOTHING, VEHICLE) found significant differences in the frequency of occurrence of subordinate and basic level tags assigned to resources in the FRUIT content category and of superordinate and basic level tags assigned to resources in the CLOTHING content category. This study suggests that variation in the level of abstraction of content related tags is natural in that perception and understanding arise out of the individual's contextualized experiences of engaging with objects.

    Abstract
    On the possible role of classification schemes in the production of knowledge in organizations
    Content
    The notion of the classification scheme as a transitional element or "boundary object" (Star, 1989) offers an alternative to the more traditional approach that views classification as an organizational structure imposed upon a body of knowledge to facilitate access within a universal and frequently static framework. Recognition of the underlying relationship between user access and the collective knowledge structures that are the basis for knowledge production indicates the dynamic role of classification in supporting coherence and articulation across heterogeneous contexts. To this end, it is argued that the library should be an active participant in the production of knowledge, and that this role can be effected by the development of classificatory structures that can support the needs of a diverse information ecology consisting of a complex web of interacting agents, users, and technologies. Within such an information ecology, a classificatory structure cannot follow a one-size-fits-all paradigm but must evolve in cooperative interaction between librarians and their user groups.

    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.

    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
    Structural differences between systems of classification and categorization lead to meaningful differences in the contexts within which information can be apprehended. Examination of systemic properties, forms of interaction and functional capabilities that distinguish classification and categorization can identify the fundamental features that influence the conceptual context of an information system and contribute to its utility as a meaningful information environment.

    Abstract
    Controlled vocabulary and fixed citation order are two of the mechanisms used to effect collocation in traditional bibliographic classification schemes. Analysis of the rationale underlying application of each of these mechanisms provides a framework for the development of nontraditional approaches to the organization of resources available an the World Wide Web. When supported by an extralinguistic faceted vocabulary of concepts, this framework facilitates construction and implementation of flexible, dynamic indexing systems that can be applied in the design of electronic information systems and the organization of Web-based knowledge resources.

    Abstract
    Examination of the systemic properties and forms of interaction that characterize classification and categorization reveals fundamental syntactic differences between the structure of classification systems and the structure of categorization systems. These distinctions lead to meaningful differences in the contexts within which information can be apprehended and influence the semantic information available to the individual. Structural and semantic differences between classification and categorization are differences that make a difference in the information environment by influencing the functional activities of an information system and by contributing to its constitution as an information environment.

    Abstract
    Search statements in this revision process can be viewed as a 'move' in the overall search strategy. Very little is known about how end users develop and revise their search strategies. A study was conducted to analyse the moves made in 244 data base searches conducted by 26 medical students at the University of North Carolina at Chapel Hill. Students search INQUIRER, a data base of facts and concepts in microbiology. The searches were conducted during a 3-week period in spring 1990 and were recorded by the INQUIRER system. Each search statement was categorised, using Fidel's online searching moves (S. Online review 9(1985) S.61-74) and Bates' search tactics (s. JASIS 30(1979) S.205-214). Further analyses indicated that the most common moves were Browse/Specity, Select Exhaust, Intersect, and Vary, and that selection of moves varied by student and by problem. Analysis of search tactics (combinations of moves) identified 5 common search approaches. The results of this study have implcations for future research on search behaviours, for thedesign of system interfaces and data base structures, and for the training of end users
