    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
    Machine-Readable Cataloging (MARC) is currently the most broadly used bibliographic standard for encoding and exchanging bibliographic data. However, MARC may not fully support representation of the dynamic nature and semantics of digital resources because of its rigid and single-layered linear structure. The Functional Requirements for Bibliographic Records (FRBR) model, which is designed to overcome the problems of MARC, does not provide sufficient data elements and adopts a predetermined hierarchy. A flexible structure for bibliographic data with detailed data elements is needed. Integrating MARC format with the hierarchical structure of FRBR is one approach to meet this need. The purpose of this research is to propose an approach that can facilitate interoperability between MARC and FRBR by providing a conceptual structure that can function as a mediator between MARC data elements and FRBR attributes.

    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
    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.
