1Hajibayova, L.: (Un)theorizing citizen science : investigation of theories applied to citizen science studies.
In: Journal of the Association for Information Science and Technology. 71(2020) no.8, S.916-926.
Abstract: This article provides an analysis of theories and methodologies that have been applied in citizen science research. This study suggests a significant contribution of citizen science to various disciplines as well as overall science education, literacy, and development. A solid theoretical grounding of citizen science research, coupled with application of pertinent emergent theories to various processes associated with scientific inquiry and discovery, suggests the disciplinary traits and unique contributions. This study proposes that the current pace of citizen science research, empowered by ordinary citizens as well as technological affordances, provides solid evidence to warrant further development of citizen science as a unique discipline that can strengthen and democratize scientific inquiry.

2Buente, W. ; Baybayan, C.K. ; Hajibayova, L. ; McCorkhill, M. ; Panchyshyn, R.: Exploring the renaissance of wayfinding and voyaging through the lens of knowledge representation, organization and discovery systems.
In: Journal of documentation. 76(2020) no.6, S.1279-1293.
Abstract: The purpose of this paper is to provide a critical analysis from an ethical perspective of how the concept of indigenous wayfinding and voyaging is mapped in knowledge representation, organization and discovery systems. Design/methodology/approach In this study, the Dewey Decimal Classification, the Library of Congress Subject Headings, the Library of Congress Classifications systems and the Web of Science citation database were methodically examined to determine how these systems represent and facilitate the discovery of indigenous knowledge of wayfinding and voyaging. Findings The analysis revealed that there was no dedicated representation of the indigenous practices of wayfinding and voyaging in the major knowledge representation, organization and discovery systems. By scattering indigenous practice across various, often very broad and unrelated classes, coherence in the record is disrupted, resulting in misrepresentation of these indigenous concepts. Originality/value This study contributes to a relatively limited research literature on representation and organization of indigenous knowledge of wayfinding and voyaging. This study calls to foster a better understanding and appreciation for the rich knowledge that indigenous cultures provide for an enlightened society.

4Hajibayova, L. ; Latham, K.F.: Exploring museum crowdsourcing projects through Bordieu's lens.
In: Knowledge organization. 44(2017) no.7, S.506-514.
Abstract: Museum crowdsourcing projects have drastically changed the ways in which individuals engage with cultural objects. In particular, individuals' participation in representation of cultural objects through creating, sharing, and curating museum cultural objects contributes to the creation of multifaceted and rich representation of cultural objects as well as transgression of institutional boundaries between cultural heritage institutions. Applying Bourdieu's (2010) conceptualization of cultural capital to museum crowdsourcing initiatives, this study suggests that cultural objects should be considered not only in relation to other objects, but also in relation to the social structure of the world and suggests that successful engagement with the crowd is grounded on an understanding of engaged individuals' cultural capital and habitus. This approach will facilitate creation of not only multifaceted and multivalent representation of cultural objects but also ensure sustainable and meaningful engagement of individuals.

5Hajibayova, L. ; Jacob, E.K.: Factors influencing user-generated vocabularies : how basic are basic level terms?.
In: Knowledge organization. 42(2015) no.2, S.102-112.
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: 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.

7Hajibayova, L. ; Jacob, E.K.: Investigation of levels of abstraction in user-generated tagging vocabularies : a case of wild or tamed categorization?.
In: Knowledge organization in the 21st century: between historical patterns and future prospects. Proceedings of the Thirteenth International ISKO Conference 19-22 May 2014, Kraków, Poland. Ed.: Wieslaw Babik. Würzburg : Ergon Verlag, 2014. S.397-404.

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.

8Hajibayova, L. ; Jacob, E.K.: ¬A theoretical framework for operationalizing basic level categories in knowledge organization research.
In: Categories, contexts and relations in knowledge organization: Proceedings of the Twelfth International ISKO Conference 6-9 August 2012, Mysore, India. Eds.: Neelameghan, A. u. K.S. Raghavan. Würzburg : Ergon Verlag, 2012. S.159-165.
(Advances in knowledge organization; vol.13)
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.

9George, N.L. ; Jacob, E.K. ; Guo, L. ; Hajibayova, L. ; Chuttur, M.Y.: ¬A case study of tagging patterns in del.icio.us.
In: Culture and identity in knowledge organization: Proceedings of the Tenth International ISKO Conference 5-8 August 2008, Montreal, Canada. Ed. by Clément Arsenault and Joseph T. Tennis. Würzburg : Ergon Verlag, 2008. S.164-169.
(Advances in knowledge organization; vol.11)
Inhalt: 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.
