Usefulness of social tagging in organizing and providing access to the web: An analysis of indexing consistency and quality
This dissertation research points out major challenging problems with current Knowledge Organization (KO) systems, such as subject gateways or web directories: (1) the current systems use traditional knowledge organization systems based on controlled vocabulary which is not very well suited to web resources, and (2) information is organized by professionals not by users, which means it does not reflect intuitively and instantaneously expressed users’ current needs. In order to explore users’ needs, I examined social tags which are user-generated uncontrolled vocabulary. As investment in professionally-developed subject gateways and web directories diminishes (support for both BUBL and Intute, examined in this study, is being discontinued), understanding characteristics of social tagging becomes even more critical.
Several researchers have discussed social tagging behavior and its usefulness for classification or retrieval; however, further research is needed to qualitatively and quantitatively investigate social tagging in order to verify its quality and benefit. This research particularly examined the indexing consistency of social tagging in comparison to professional indexing to examine the quality and efficacy of tagging. The data analysis was divided into three phases: analysis of indexing consistency, analysis of tagging effectiveness, and analysis of tag attributes. Most indexing consistency studies have been conducted with a small number of professional indexers, and they tended to exclude users. Furthermore, the studies mainly have focused on physical library collections. This dissertation research bridged these gaps by (1) extending the scope of resources to various web documents indexed by users and (2) employing the Information Retrieval (IR) Vector Space Model (VSM) - based indexing consistency method since it is suitable for dealing with a large number of indexers. As a second phase, an analysis of tagging effectiveness with tagging exhaustivity and tag specificity was conducted to ameliorate the drawbacks of consistency analysis based on only the quantitative measures of vocabulary matching. Finally, to investigate tagging pattern and behaviors, a content analysis on tag attributes was conducted based on the FRBR model.
The findings revealed that there was greater consistency over all subjects among taggers compared to that for two groups of professionals. The analysis of tagging exhaustivity and tag specificity in relation to tagging effectiveness was conducted to ameliorate difficulties associated with limitations in the analysis of indexing consistency based on only the quantitative measures of vocabulary matching. Examination of exhaustivity and specificity of social tags provided insights into particular characteristics of tagging behavior and its variation across subjects. To further investigate the quality of tags, a Latent Semantic Analysis (LSA) was conducted to determine to what extent tags are conceptually related to professionals’ keywords and it was found that tags of higher specificity tended to have a higher semantic relatedness to professionals’ keywords. This leads to the conclusion that the term’s power as a differentiator is related to its semantic relatedness to documents. The findings on tag attributes identified the important bibliographic attributes of tags beyond describing subjects or topics of a document. The findings also showed that tags have essential attributes matching those defined in FRBR. Furthermore, in terms of specific subject areas, the findings originally identified that taggers exhibited different tagging behaviors representing distinctive features and tendencies on web documents characterizing digital heterogeneous media resources. These results have led to the conclusion that there should be an increased awareness of diverse user needs by subject in order to improve metadata in practical applications.
This dissertation research is the first necessary step to utilize social tagging in digital information organization by verifying the quality and efficacy of social tagging. This dissertation research combined both quantitative (statistics) and qualitative (content analysis using FRBR) approaches to vocabulary analysis of tags which provided a more complete examination of the quality of tags. Through the detailed analysis of tag properties undertaken in this dissertation, we have a clearer understanding of the extent to which social tagging can be used to replace (and in some cases to improve upon) professional indexing

A Child-Driven Metadata Schema: A Holistic Analysis of Children\u27s Cognitive Processes During Book Selection
The purpose of this study was to construct a child-driven metadata schema by understanding children\u27s cognitive processes and behaviors during book selection. Existing knowledge organization systems including metadata schemas and previous literature in the metadata domain have shown that there is a no specialized metadata schema that describes children\u27s resources that also is developed by children. It is clear that children require a new or alternative child-driven metadata schema. Child-driven metadata elements reflected the children\u27s cognitive perceptions that could allow children to intuitively and easily find books in an online cataloging system. The literature of development of literacy skills claims that the positive experiences of selecting books empower children\u27s motivation for developing literacy skills. Therefore, creating a child-driven metadata schema not only contributes to the improvement of knowledge organization systems reflecting children\u27s information behavior and cognitive process, but also improves children\u27s literacy and reading skills.
Broader research questions included what metadata elements do children like to use? What elements should a child-driven metadata schema include? In order to answer these research questions, a triangulated qualitative research design consisting of questionnaires, paired think-aloud, interview, and diaries were used with 22 child participants between the ages of 6 and 9. A holistic understanding of the children\u27s cognitive processes during book selection as a foundation of a child-driven metadata schema displays an early stage of an ontological contour for a children\u27s knowledge organization system. A child-driven metadata schema constructed in this study is apt to include different metadata elements from those metadata elements existing in current cataloging standards. A child-driven metadata schema includes five classes such as story/subject, character, illustration, physical characteristics, and understandability, and thirty three metadata elements such as character\u27s names and images, book cover\u27s color, shape, textured materials, engagement element, and tone. In addition, the analysis of the relationship between emergent emotional vocabularies and cognitive factors and facets illustrated the important role of emotion and attention in children\u27s information processing and seeking behaviors
Emergent digital services in public libraries : a domain study
Purpose: This paper explores the emergence of digital services in the public library domain via an extensive study of the websites of all Scottish public library services Design/methodology/approach: In a 4 month period all 32 of Scotland’s public library authority websites were visited by a researcher. The goal of the researcher was to record the options available from the library homepages in the following way: •Role of library in providing page content: content provider or access provider? •Was the page providing a digital service? •What was the audience for the page? Adult, child, or not specified? •Description of page content •Any noted usability issues Each site was only visited to three levels below that of the initial homepage. Findings: The study found a good standard of innovation in digital services around LMS functions, offering users the ability to keep in control of their borrowing and reserving. In addition there was a consistent set of electronic reference resources subscribed to by multiple libraries, offering high quality information both within the library and for library members from their home or workplace. Problems were found with regards to guidance on the usage of these resources, as well as confusion and inconsistency in terminology usage across different library services. Research limitations/implications: The paper examines only Scottish public library sites, thus can only claim to be representative of that country. It also can only represent the sites at the time they were examined. Practical implications: The paper should be of interest to public and other librarians interested in patterns across web sites in their sector. Originality/value: This is the first national study of Scottish public library websites and its findings should be of value as a result

Visual perception in relation to levels of meaning for children: An exploratory study.
This study explores distinct levels of meaning from images of picture books perceived by 3- to 5-year-old children and investigates how the certain visual perception factors influence children's meaning making and if these factors are correlated. The literature review supports associations among visual perception, information, picture books, meaning, and children. Visual perception serves as the first channel that filters and interprets visual information, and picture books provide visual and verbal experience for children, who constantly search for meaning. Children age 3 to 5 years are potential users of picture books because pictorial information is considered useful to children's learning tasks. Previous research reveals that various factors influence visual perception, and meaning has been mostly associated with its semantic significance in information retrieval. In information science, little research has focused on young children's own way of categorizing information, especially visual information. In order to investigate the distinct levels of meaning perceived by children, the investigation employed both qualitative and quantitative methods including unobtrusive and participant observation, factor analysis, content analysis, and case study. The result of this study contributes to understanding the cognitive process of children related to visual literacy and their interpreting visual information in a digital environment
