Generation of Classificatory Metadata for Web Resources using Social Tags

With the increasing popularity of social tagging systems, the potential for using social tags as a source of metadata is being explored. Social tagging systems can simplify the involvement of a large number of users and improve the metadata generation process, especially for semantic metadata. This research aims to find a method to categorize web resources using social tags as metadata. In this research, social tagging systems are a mechanism to allow non-professional catalogers to participate in metadata generation. Because social tags are not from a controlled vocabulary, there are issues that have to be addressed in finding quality terms to represent the content of a resource. This research examines ways to deal with those issues to obtain a set of tags representing the resource from the tags provided by users.Two measurements that measure the importance of a tag are introduced. Annotation Dominance (AD) is a measurement of how much a tag term is agreed to by users. Another is Cross Resources Annotation Discrimination (CRAD), a measurement to discriminate tags in the collection. It is designed to remove tags that are used broadly or narrowly in the collection. Further, the study suggests a process to identify and to manage compound tags. The research aims to select important annotations (meta-terms) and remove meaningless ones (noise) from the tag set. This study, therefore, suggests two main measurements for getting a subset of tags with classification potential. To evaluate the proposed approach to find classificatory metadata candidates, we rely on users' relevance judgments comparing suggested tag terms and expert metadata terms. Human judges rate how relevant each term is on an n-point scale based on the relevance of each of the terms for the given resource

Personal Health Information Management by College Students: Patterns of Inaction

Introduction. College students\u27 diverse health information management activities are rarely studied within a personal health context. Our study identified an inactive group of college students and their information management activities to understand what factors determine inactivity. Methods. An online questionnaire was distributed to college students enrolled in a state-owned university in the USA between January and March 2017. A total of eighty-four questions on twelve information management activities grouped by seven types of personal health information were used to identify inactive performers within our student sample. Additionally, potential factors regarding demographics, academics, information resource types, and information workload were tested. Analysis. Our study sample includes 1,408 student responses. K-means clustering segmented the sample into two groups (inactive and active). Group differences between inactive and active personal health information managers were compared. Binary logistic regression was also performed to determine key factors predicting inactivity. Results. The inactive group (N=772, 54.80%) identified more male students, less clinic visits, and health information primarily sought through the Internet and mass media. Additionally, the awareness of personal health information management and training perceptions were found to be significant determinants of the inactivity. The inactive group proved to be lacking in most information management activities, except for discarding, and showed less interests in all types of health documents. Conclusion. Based on the inactive personal health information management group, how to collect, organize, retrieve, backup and migrate personal health documents, should be integrated into a formal college curriculum

Analysis of College Students’ Personal Health Information Activities: Online Survey

Background: With abundant personal health information at hand, individuals are faced with a critical challenge in evaluating the informational value of health care records to keep useful information and discard that which is determined useless. Young, healthy college students who were previously dependents of adult parents or caregivers are less likely to be concerned with disease management. Personal health information management (PHIM) is a special case of personal information management (PIM) that is associated with multiple interactions among varying stakeholders and systems. However, there has been limited evidence to understand informational or behavioral underpinning of the college students’ PHIM activities, which can influence their health in general throughout their lifetime. Objective: This study aimed to investigate demographic and academic profiles of college students with relevance to PHIM activities. Next, we sought to construct major PHIM-related activity components and perceptions among college students. Finally, we sought to discover major factors predicting core PHIM activities among college students we sampled. Methods: A Web survey was administered to collect responses about PHIM behaviors and perceptions among college students from the University of Kentucky from January through March 2017. A total of 1408 college students were included in the analysis. PHIM perceptions, demographics, and academic variations were used as independent variables to predict diverse PHIM activities using a principal component analysis (PCA) and hierarchical regression analyses (SPSS v.24, IBM Corp, Armonk, NY, USA). Results: Majority of the participants were female (956/1408, 67.90%), and the age distribution of this population included an adequate representation of college students of all ages. The most preferred health information resources were family (612/1408, 43.47%), health care professionals (366/1408, 26.00%), friends (27/1408, 1.91%), and the internet (157/1408, 11.15%). Organizational or curatorial activities such as Arranging, Labeling, Categorizing, and Discarding were rated low (average=3.21, average=3.02, average=2.52, and average=2.42, respectively). The PCA results suggested 3 components from perception factors labeled as follows: Assistance (alpha=.85), Awareness (alpha=.716), and Difficulty (alpha=.558). Overall, the Demographics and Academics variables were not significant in predicting dependent variables such as Labeling, Categorizing, Health Education Materials, and Discarding, whereas they were significant for other outcome variables such as Sharing, Collecting, Knowing, Insurance Information, Using, and Owning. Conclusions: College years are a significant time for students to learn decision-making skills for maintaining information, a key aspect of health records, as well as for educators to provide appropriate educational and decision aids in the environment of learning as independent adults. Our study will contribute to better understand knowledge about specific skills and perceptions for college students’ practice of effective PHIM throughout their lives

The Impact of Source Credibility on Young Adults' Health Information Activities on Facebook: Preliminary Findings

ABSTRACT Within the context of SNSs, particularly Facebook, this study aims to understand how young adults perceive the credibility of various information sources, how their information activities differ by those information sources, and how young adults' perception of credibility impacts their information activities. The results of an online survey demonstrated that young adults consider medical/health organizations and government agencies the most credible and friends the least credible for health issues. As for information activities, although young adults' intents to read postings were significantly greater than those to post questions or answers, intents of information activities were generally lower than neutral. Nevertheless, it was found that the more young adults trust information sources, the more likely they are to be involved in information activities. The results showed the potential of Facebook as a good information channel, especially for health professionals and governmental organizations.
