Citizen science is a form of research collaboration that actively involves the public in scientific research to address real‐world problems. Research designed specifically for public participation is a form of information work for which the design of tasks and supporting technologies for volunteers is critically important to the scientific outcomes. This study examines the relationship between information...
This paper is a short description of an information retrieval system enhanced by three model driven retrieval services: (1) co‐word analysis based query expansion, re‐ranking via (2) Bradfordizing and (3) author centrality. The different services each favor quite other – but still relevant – documents than pure term‐frequency based rankings. Each service can be interactively combined with each other...
This poster reports on a study of gaze behavior within a faceted library catalog. Initial results suggest that gaze behavior differs at definable stages within a search session.
Understanding, as opposed to seeing, depends on knowing the background, the context, of whatever is of interest. For this reason the creation of reference resources is foundational. Creating reference resources and making them available requires major investments of resources expertise. The benefits derived, the return on this investment, depends on the use made of them. The digital environment offers...
We present a general conceptual framework that maps relationships and dependencies among scientific data practices, types of data produced and used, and associated curation activities. As part of the Data Conservancy initiative, the framework is being elaborated through empirical studies of data practices in the earth sciences and life science and validated against use cases as curatorial services...
This research investigates blog usage pattern of college students and gender difference. The 25 statements developed for this study were used to measure students' blog usage, gender difference, attitude, and satisfaction toward using blog. The 25 statements are categorized into four areas: information sharing, social communication, management, and negative effect. The findings indicate that the students...
This article uses a technique called Web Analytics to examine the behavior of end users interacting with an online, web‐based image database that is part of a digital library. A quantitative analysis was conducted to compare the behavior of two types of visitors accessing the database (new visitors versus returning visitors). Significant behavior differences of the two groups of visitors are manifested...
This paper presents experimental results showing that a user's interaction with hierarchical classification may affect the user's conceptual structures. After performing a directed browsing task using a hierarchical classificatory structure, subjects rated as more important the concepts that were organized in the top tier of the hierarchy. The results of the study suggest that, although subjects adapted...
Palliative care is associated with life‐threatening diseases in the last phase between life and death. Although noted, the emotion, trauma, despair, and physical deterioration of this phase are not fully exposed in information behavior literature. Concerns about unmet information needs and frustrations continue. To deepen understanding of the complexity of information behavior in palliative care,...
This paper describes a ‘cultural probe’ study underpinning a user‐centered re‐design of the Greenstone digital library system's collection creation sub‐system (the Greenstone ‘Librarian’), with a focus on assisting seniors in developing Greenstone collections representing their personal history. The results of this investigation include a customized metadata set for these users' collections, and a...
Biosurveillance depends on accurate recognition of symptoms such as fever. We describe a manual bootstrapping method for discovering fever expressions in emergency department triage notes, which will in turn serve as seed terms for automatic discovery of novel expressions.
This paper is part of a larger research project which aims to answer whether social tagging could enhance access to web resources, and whether we could verify the usefulness of social tagging to obtain benefit from it. This paper particularly examines the indexing consistency of social tagging in comparison to professional indexing.
This study examines the relationships amongst three major usability elements – efficiency, effectiveness, and satisfaction. Based on an experiment involving twelve subjects, this pilot study measured the efficiency, effectiveness, and subjective satisfaction of an academic digital library system. The preliminary results showed all three usability elements are highly correlated with each other. In...
This paper in advancing the understanding of the life cycle of Library 2.0 in the academic library context, describes an exploratory study in two parts: (1) Use: an exploration of user experience of Library 2.0 services; and (2) Evaluation: an evaluation of impact of Library 2.0 services on academic libraries and users. Through the dual lenses of social constructivism and Phenomenology, this study...
This pilot study examines the semantic structure of tag space in Library and Information Science (LIS) using confirmatory factor analysis of social tags from Delicious.com. This study is one of the few studies to employ structural equation modelling (SEM) in investigating dimensions of Web spaces based on social tagging data. This study examines the post data collected from 34 LIS related websites...
Internet usage continues to increase and people spend more time chatting and forming friendships online. Out of this phenomenon, a new way of speaking is emerging. This poster reports on a pilot study that examines non‐standard English features in World of Warcraft chat.
Manual sorting of published journal articles into several pre‐defined subsets for the purpose of qualitative analysis is common practice in social science research. Unfortunately, this can be a time‐consuming process which requires the attention of a subject specialist, and relies on various measures of inter‐rater reliability to ensure that the results are valid and reproducible to serve as a basis...
This study compares some of the behavioural characteristics of two recommender systems for scholarly articles in a digital library: a usage‐based recommender and an experimental citation‐based recommender. Experimental results show that article recommendations based only on usage data are slightly better at solving the perennial data‐sparsity problem that plagues collaborative filtering recommenders...
This poster presents findings on student development of contemporary learning abilities among 14 middle school students enrolled in a year‐long elective game design class. The study measures students' change in attitudes towards the activities in which they participate, through their responses to a self‐report survey of frequency, motivation, and self‐reported knowledge. T‐test statistics were used...
