What Does it Take to Make Discovery a Success?: A Survey of Discovery Tool Adoption, Instruction, and Evaluation Among Academic Libraries

Discovery tools have been widely adopted by academic libraries, yet little information exists that connects common practices regarding discovery tool implementation, maintenance, assessment, and staffing with conventions for research and instruction. The authors surveyed heads of reference and instruction departments in research and land-grant university libraries. The survey results revealed common practices with discovery tools among academic libraries. This study also draws connections between operational, instructional, and assessment practices and perceptions that participants have of the success of their discovery tool. Participants who indicated successful implementation of their discovery tool hailed from institutions that made significant commitments to the operations, maintenance, and acceptance of their discovery tool. Participants who indicated an unsuccessful implementation, or who were unsure about the success of their implementation, did not make lasting commitments to the technical maintenance, operations, and acceptance of their discovery tool

Open access to educational resources in energy and sustainability: Usability evaluation prototype for repositories

The purpose of this paper is to show a PhD dissertation research plan, which aims to assess whether the users’ experience of users to perform various tasks in an open access repository, increases by integrating Discovery Tools. The tasks to perform by the users are management and information design, dissemination and searches of open educational resources (OER) of sustainability energy. This research aims to develop a usability evaluation prototype which will offer new insights in the design of the information architecture. In the first stage, the criteria will be selected to measure the level of usability of the tasks to evaluate and develop the analysis of the current interactive design of the web repository. In the second stage, will consist of measure, once implemented the Discovery Tools in the web repository and check the usability level increase in relation with the criteria. In this paper you could find aspects as the motivations and the context in which it will develop this research, state of the art, hypothesis, research objectives, aspects of the methodology of the research, developed under the method of mixed layout, the current an expected contribution, the results and the validation and dissertation status. The results will contribute for detect new criteria and parameters for provide flexible interfaces, specifically for the web repositories, which are a part of the technological ecosystem of the scientific activity

The Alliance of Genome Resources: Building a Modern Data Ecosystem for Model Organism Databases.

Model organisms are essential experimental platforms for discovering gene functions, defining protein and genetic networks, uncovering functional consequences of human genome variation, and for modeling human disease. For decades, researchers who use model organisms have relied on Model Organism Databases (MODs) and the Gene Ontology Consortium (GOC) for expertly curated annotations, and for access to integrated genomic and biological information obtained from the scientific literature and public data archives. Through the development and enforcement of data and semantic standards, these genome resources provide rapid access to the collected knowledge of model organisms in human readable and computation-ready formats that would otherwise require countless hours for individual researchers to assemble on their own. Since their inception, the MODs for the predominant biomedical model organisms [Mus sp (laboratory mouse), Saccharomyces cerevisiae, Drosophila melanogaster, Caenorhabditis elegans, Danio rerio, and Rattus norvegicus] along with the GOC have operated as a network of independent, highly collaborative genome resources. In 2016, these six MODs and the GOC joined forces as the Alliance of Genome Resources (the Alliance). By implementing shared programmatic access methods and data-specific web pages with a unified "look and feel," the Alliance is tackling barriers that have limited the ability of researchers to easily compare common data types and annotations across model organisms. To adapt to the rapidly changing landscape for evaluating and funding core data resources, the Alliance is building a modern, extensible, and operationally efficient "knowledge commons" for model organisms using shared, modular infrastructure

Evaluating product search and recommender systems for E-commerce environments

Online systems that help users select the most preferential item from a large electronic catalog are known as product search and recommender systems. Evaluation of various proposed technologies is essential for further development in this area. This paper describes the design and implementation of two user studies in which a particular product search tool, known as example critiquing, was evaluated against a chosen baseline model. The results confirm that example critiquing significantly reduces users' task time and error rate while increasing decision accuracy. Additionally, the results of the second user study show that a particular implementation of example critiquing also made users more confident about their choices. The main contribution is that through these two user studies, an evaluation framework of three criteria was successfully identified, which can be used for evaluating general product search and recommender systems in E-commerce environments. These two experiments and the actual procedures also shed light on some of the most important issues which need to be considered for evaluating such tools, such as the preparation of materials for evaluation, user task design, the context of evaluation, the criteria, the measures and the methodology of result analyse

The Perfect Storm: Examining User Experience and Conducting a Usability Test to Investigate a Disruptive Academic Library Web Site Redevelopment

The researchers conducted a task-based usability test of the effectiveness of online research beginning on the library Web site homepage. The participants included five university faculty members, six graduate students, and six undergraduate students. All participants reported feeling satisfied with their overall research experience, though most were unable to effectively complete all the research tasks of the test. The researchers identified weaknesses in the approach and process of many participants, and overall usability issues of the library discovery tool and other library Web site pages and research interfaces. Findings indicate the need to strategically incorporate self-service information literacy and research skills help into the library Web site, and to implement navigation and design changes to the library homepage, discovery tool interface, online catalog, and across all the library\u27s Web services

Discovering Usability : Comparing two discovery systems at one academic library

In the spring of 2013, the University Library at the University of Illinois at Chicago was in the unique position of having access to two discovery systems, Summon and WorldCat Local, at the same time. When tasked with choosing between the two systems, librarians undertook a usability study of Summon and WorldCat Local. The goal of this study was two-fold: to test the ease-of-use of each discovery system with an eye toward identifying one tool to retain for the longer term, and to learn about the search behaviors of different types of user groups. Eighteen subjects, consisting of undergraduate students, graduate students and faculty, participated in the study. Participants performed usability tasks using each tool and answered pre-task and post-task questions. While there was no clear preference among study participants for either discovery layer, individual groups did express preferences. Faculty, for example, preferred Summon to WorldCat Local at a rate of five to one. The study findings are explored in detail through an examination of the three major data sets produced by the usability test instrument: results derived from tasks performed by participants as part of the study; themes and trends identified by the investigators within the recorded participant tests; and discovery tool preferences as determined from pre-task and post-task questionnaires administered to study participants. This study has implications for librarians engaged in information literacy instruction; those considering implementing discovery tools, as well as for librarians currently using Summon or WorldCat Local at their libraries

A zoomable shopping browser using a graphic-treemap

Effective and efficient navigation and representation of the entire structure of the product catalogue is one of the important factors for on-line market. This paper proposes an application using Treemaps visualization to enhance the functionality of online product category. We aim to develop high-quality catalog interfaces in terms of readability, understandability and comprehension by integrating graphics into Treemaps. We applied two types of Treemaps: 1) Slice-and-Dice Treemap, 2) Squarified Treemap, into the on-line catalogue to address the small windowproblem allowing buyers to overview and navigate large product categories dynamically. We also use a history bar that locates on the top of each category and sub-category to provide a 2.5-dimensional view of contextual information. © 2009 IEEE
