The goal of this study is to examine and compare how library users access, use, and interact with two social discovery systems used in two Canadian public library systems. Transaction log analysis data are analyzed over a four‐month period from the AquaBrowser and BiblioCommons social discovery tools used in the Halifax and Edmonton public library systems. The results obtained from the transaction...
In order to improve our understanding of scientific data users' data usage behaviors, which has been rarely studied in the fourth science paradigm—data‐intensive science, this study conducted a content analysis of publications associated with a frequently cited data‐intensive science project, called Sloan Digital Sky Survey (SDSS). We analyzed 200 SDSS‐related publications and identified the data...
This paper analyses the tagging patterns on delicious.com for a set of documents (URLs) over a 4 year period using informetrics methods to assess how collaborative tagging supports and enhances traditional document indexing. Results of the study show that there is still a mix of consensus and divergence in tagging term use and tagging patterns. While some of the chosen URLs maintained or even increased...
This paper reports the result of a transaction log analysis on two faceted library catalogs (University of North Carolina at Chapel Hill (UNC) Library catalog and Phoenix Public Library (PPL) catalog). The goal is to investigate people's searching behavior with the faceted catalogs in an academic library and a public library. Two large data sets (with 504,142 logs for 40 days, and 1,010,239 logs for...
Collections of artifacts, images, texts, and other cultural objects are not arbitrary aggregations, but are designed to support specific research and scholarly activities. Collection‐level metadata directly supports this objective, providing critical contextual information. However, exploiting this information, especially in a semantic web environment of linked data, requires a precise formalization...
In this paper we compare author cocitation analysis (ACA) results for the highly collaborative stem cell (SC) research field 2004–2009 using three types of ACA: all‐author, first‐author, and last‐author. The latter of these, introduced here for the first time, is found to be an excellent compromise between first‐ and all‐author ACAs in that (a) Scopus directly supports it and (b) its results are close...
Over the last few years, faceted search emerged as an attractive alternative to the traditional “text box” search and has become one of the standard ways of interaction on many e‐commerce sites. However, these applications of faceted search are limited to domains where the objects of interests have already been classified along several independent dimensions, such as price, year, or brand. While automatic...
Today's readers of scholarly literature want to read more in less time. With this in mind, this study applies the idea of the functional unit to the use of digital documents. A functional unit is the smallest information unit with a distinct function within the Introduction, Methods, Results and Discussion components of scholarly journal articles. Through a review and analysis of the literature and...
Bias is inherent in classification systems because culture and worldview are linked. A Moroccan library's specialized collection on the Muslim West (Ibn Rushd) offers culturally adapted intellectual access to materials through the Ibn Rushd Thesaurus (IRT) and accompanying classification scheme. This paper compares the specialized Moroccan scheme for describing location in the historical and modern...
While some libraries have begun to offer customized mobile applications for their online public access catalogs (OPACs), little research has investigated the relative costs and benefits associated with developing such applications. To investigate this tradeoff, we have developed a prototype Mobile search application for the University of Texas library catalog (MUT). Our experience indicates that mobile...
This paper reports a study on the relationships between work tasks and users' performance when they interact with information systems, that is, interaction performance. An experiment with 24 participants was conducted to explore the issue. The participants were asked to search for useful information to support the completion of six simulated work task situations from operational information systems...
This paper reports on the findings of a user study that explored how searchers tend to fixate on information associated with different relevance criteria in the web during the relevance judgment process. The user study involved the completion of questionnaires, use of eye tracking technology, talk aloud protocols and post‐search interviews. As opposed to previous studies, the present research asked...
Newspapers have long been rich resources for historians. In the past several years many historical newspapers have been digitized, offering the promise of improved access and powerful searching. In this research, we focus on historians' needs for searching collections of newspapers and managing the information they find. This is a deeper and more targeted investigation than much previous work that...
Hjørland proposes a typology of four epistemological views in analyzing professional knowledge organization systems. In this study, we identified all four views as components of personal information organization in the current hierarchical folder structures on personal computers. The typology enabled us to synthesize the varieties and commonalities within the large number of particular information...
People can acquire health information intentionally or unintentionally from a variety of sources, and some health messages could contradict others. This study employed in‐depth qualitative interviews with college students to understand their perceptions of tanning‐related conflicting health information. We report on the inconsistency perceived by college students and their strategies to make sense...
Pre‐handoff “chart biopsy” involves the brief reviewing by a clinician of a patient's record prior to accepting responsibility for the care of that patient. It is an information seeking activity enabled by electronic health records. This paper reports on a qualitative study of chart biopsies conducted by General Medicine physicians in a large quaternary teaching hospital prior to discussing possible...
Opinion and use of thumbnails in web search is still divided, despite agreement over their particular value during re‐finding tasks. In this paper we introduce the idea of a Revisit Rack that, during re‐finding tasks, presents thumbnails together at the top of the page rather than beside each result, so that users can more effectively utilize visual recognition without scrolling. The results of a...
This panel aims at giving an overview on the situation of information science in a few selected European countries/regions (Scandinavia, France and former Yugoslavian countries). At the beginning the panelists will give an outline on the discipline in their country. In particular the following questions will be addressed:
What is the state‐of‐the‐art of information science with regard to academic...
This study investigates how people's credibility assessment processes have evolved as they engage in increasingly diverse types of online activities beyond seeking for information or reading online news. Using an online activity diary method, information on people's online activities and their associated credibility assessment processes were collected at multiple points throughout the day for three...
Users judge the credibility of websites while browsing for information. The criteria that influence how they judge the credibility depend on many factors. In this study we found that computer expertise had a strong impact on what criteria users used in their credibility judgments. Participants evaluated websites they found while searching and described their credibility evaluation process. The criteria...
