Collaborative Filtering Based on Bi-Relational Data Representation
Authors: Szwabe Andrzej , Misiorek Pawel , Ciesielczyk Michal , Jedrzejek Czeslaw 
Published: February 2013

Abstract
Widely-referenced approaches to collaborative filtering (CF) are based on the use of an input matrix that represents each user profile as a vector in a space of items and each item as a vector in a space of users. When the behavioral input data have the form of (userX, likes, itemY) and (userX, dislikes, itemY) triples one has to propose a representation of the user feedback data that is more suitable for the use of propositional data than the ordinary user-item ratings matrix. We propose to use an element-fact matrix, in which columns represent RDF-like behavioral data triples and rows represent users, items, and relations. By following such a triple-based approach to the bi-relational behavioral data representation we are able to improve the quality of collaborative filtering. One of the key findings of the research presented in this paper is that the proposed bi-relational behavioral data representation, while combined with reflective matrix processing, significantly outperforms state-of-the-art collaborative filtering methods based on the use of a ‘standard’ user-item matrix.

Background IDX184 is a liver-targeted nucleotide prodrug that selectively inhibits HCV NS5B polymerase. Methods This randomized, double-blind, placebo-controlled, ascending-dose study investigated the antiviral activity, safety and pharmacokinetics of IDX184 plus pegylated interferon-α2a and ribavirin (P/R) in treatment-naive patients with genotype-1 HCV. A total of 81 patients with baseline HCV RNA≥5 log10 IU/ml, alanine aminotransferase ≤3x upper limit of normal and compensated liver disease were dosed. Sequential cohorts of 20 patients, randomized 16:4 (active:placebo), received IDX184 for 14 days at rising daily doses of 50, 100, 150 or 200 mg in combination with P/R for 14 days. Results At the end of triple dosing, HCV RNA changes from baseline (mean ±sd log 10) and proportion of patients achieving undetectable viral load (<15 IU/ml) based on the efficacy-evaluable population were -2.7 ±1.3 (13%), -4.0 ±1.7 (50%), -4.2 ±1.9 (50%), -4.1 ±1.2 (40%), -4.3 ±1.5 (29%) and -3.7 ±1.2 (25%) for the 50 mg once daily, 50 mg twice daily, 100 mg once daily, 150 mg once daily, 100 mg twice daily and 200 mg once daily IDX184 doses, respectively. P/R alone resulted in a reduction of -1.5 ±1.3 log10 with only 6% of patients with undetectable viral load. Patients with genotypes-1a or -1b responded similarly. No viral breakthrough or resistance associated with IDX184 was observed. Anti-HCV activity of IDX184 correlated with plasma exposure of its nucleoside metabolite 2′-methylguanosine. Most adverse events were mild or moderate in severity and were consistent with those associated with P/R. The most common adverse events were fatigue and headache. Conclusions IDX184 in combination with P/R for 14 days was well tolerated and demonstrated greater antiviral activity with more patients achieving undetectable viral load than P/R.

Published: February 2013

Digitization has bestowed upon librarians and archivists of the late 20th and early 21st centuries the opportunity to reexamine how they access their collections. It draws these two traditional groups together with IT specialists in order to collaborate on this new great challenge. In this paper, the authors offer a strategy for adapting a library system to traditional archival practice.
A Dynamic Methodology for Improving the Search Experience
Authors: Kerchner Marcia D. 
Published: February 2013

In the early years of modern information retrieval, the fundamental way in which we understood and evaluated search performance was by measuring precision and recall. In recent decades, however, models of evaluation have expanded to incorporate the information-seeking task and the quality of its outcome, as well as the value of the information to the user. We have developed a systems engineering-based methodology for improving the whole search experience. The approach focuses on understanding users’ information-seeking problems, understanding who has the problems, and applying solutions that address these problems. This information is gathered through ongoing analysis of site-usage reports, satisfaction surveys, Help Desk reports, and a working relationship with the business owners.
Usability Testing of a Large, Multidisciplinary Library Database: Basic Search and Visual Search
Authors: Fagan Jody Condit 
Published: February 2013

Visual search interfaces have been shown by researchers to assist users with information search and retrieval. Recently, several major library vendors have added visual search interfaces or functions to their products. For public service librarians, perhaps the most critical area of interest is the extent to which visual search interfaces and text-based search interfaces support research. This study presents the results of eight full-scale usability tests of both the EBSCOhost Basic Search and Visual Search in the context of a large liberal arts university.
OpenSearch and SRU: A Continuum of Searching
Authors: LeVan Ralph 
Published: February 2013

Not all library content can be exposed as HTML pages for harvesting by search engines such as Google and Yahoo!. If a library instead exposes its content through a local search interface, that content can then be found by users of metasearch engines such as A9 and Vivísimo. The functionality provided by the local search engine will affect the functionality of the metasearch engine and the findability of the library’s content. This paper describes that situation and some emerging standards in the metasearch arena that choose different balance points between functionality and ease of implementation.
Checking Out Facebook.com: The Impact of a Digital Trend on Academic Libraries
Authors: Charnigo Laurie , Barnett-Ellis Paula 
Published: February 2013

While the burgeoning trend in online social networks has gained much attention from the media, few studies in library science have yet to address the topic in depth. This article reports on a survey of 126 academic librarians concerning their perspectives toward Facebook.com, an online network for students. Findings suggest that librarians are overwhelmingly aware of the “Facebook phenomenon.” Those who are most enthusiastic about the potential of online social networking suggested ideas for using Facebook to promote library services and events. Few individuals reported problems or distractions as a result of patrons accessing Facebook in the library. When problems have arisen, strict regulation of access to the site seems unfavorable. While some librarians were excited about the possibilities of Facebook, the majority surveyed appeared to consider Facebook outside the purview of professional librarianship.
Introducing Zoomify Image
Authors: Smith Adam 
Published: February 2013

Zoomify Image is a mature product for easily publishing large, high-resolution images on the Web. End users view these images with existing Webbrowser software as quickly as they do normal, downsampled images. A Flash-based Zoomifyer client asynchronously streams image data to the Web browser as needed, resulting in response times approaching those of desktop applications using minimal bandwidth. The author, a librarian at Cornell University and the principal architect of a small, open-source company, worked closely with Zoomify to produce a cross-platform, opensource implementation of that company’s image-processing software and discusses how to easily deploy the product into a widely used Webpublishing environment. Limitations are also discussed as are areas of improvement and alternatives.
Index Blending: Enabling the Development of Definitive, Discipline-Specific Resources
Authors: Brooks Sam , Herrick Mark 
Published: February 2013

Index Blending is the process of database development whereby various components are merged and refined to create a single encompassing source of information. Once a research need is determined for a given area of study, existing resources are examined for value and possible contribution to the end product. Index Blending focuses on the quality of bibliographic records as the primary factor with the addition of full text to enhance the end user’s research experience as an added convenience. Key examples of the process of Index Blending involve the fields of communication and mass media, hospitality and tourism, as well as computers and applied sciences. When academia, vendors, subject experts, lexicographers, and other contributors are brought together through the various factors associated with Index Blending, relevant discipline-specific research may be greatly enhanced.

Revitalizing the Library OPAC: Interface, Searching, and Display Challenges
Authors: Mi Jia , Weng Cathy 
Published: February 2013

The behavior of academic library users has drastically changed in recent years. Internet search engines have become the preferred tool over the library online public access catalog (OPAC) for finding information. Libraries are losing ground to online search engines. In this paper, two aspects of OPAC use are studied: (1) the current OPAC interface and searching capabilities, and (2) the OPAC bibliographic display. The purpose of the study is to find answers to the following questions: Why is the current OPAC ineffective? What can libraries and librarians do to deliver an OPAC that is as good as search engines to better serve our users? Revitalizing the library OPAC is one of the pressing issues that has to be accomplished.
FRBRization of a Library Catalog: Better Collocation of Records, Leading to Enhanced Search, Retrieval, and Display
Authors: Dickey Timothy J. 
Published: February 2013

The Functional Requirements for Bibliographic Records (FRBR)’s hierarchical system defines families of bibliographic relationship between records and collocates them better than most extant bibliographic systems. Certain library materials (especially audio-visual formats) pose notable challenges to search and retrieval; the first benefits of a FRBRized system would be felt in music libraries, but research already has proven its advantages for fine arts, theology, and literature—the bulk of the non-science, technology, and mathematics collections. This report will summarize the benefits of FRBR to nextgeneration library catalogs and OPACs, and will review the handful of ILS and catalog systems currently operating with its theoretical structure.

Authors: Jeng Judy 
Published: February 2013

The aim of this research is to study the usefulness of the New Jersey Digital Highway (NJDH, www.njdigitalhighway.org) and its portal structure. The NJDH intends to provide an immersive and user-centered portal for New Jersey history and culture. The research recruited 145 participants and used a Web-based questionnaire that contained three sections: for everyone, for educators, and for curators. The feedback on the usefulness of the NJDH was positive and the portal structure was favorable. The research uncovered several reasons why some collections did not want to or could not participate. The findings also suggested priorities for further development. This study is one of the few on the evaluation of cultural heritage digital library.

Tending a Wild Garden: Library Web Design for Persons with Disabilities
Authors: Vandenbark R. Todd 
Published: February 2013

Nearly one-fifth of Americans have some form of disability, and accessibility guidelines and standards that apply to libraries are complicated, unclear, and difficult to achieve. Understanding how persons with disabilities access Web-based content is critical to accessible design. Recent research supports the use of a database-driven model for library Web development. Existing technologies offer a variety of tools to meet disabled patrons’ needs, and resources exist to assist library professionals in obtaining and evaluating product accessibility information from vendors. Librarians in charge of technology can best serve these patrons by proactively updating and adapting services as assistive technologies improve.
Geographic Information Systems: Tools for Displaying In-Library Use Data
Authors: Mandel Lauren H. 
Published: February 2013

In-library use data is crucial for modern libraries to understand the full spectrum of patron use, including patron self-service activities, circulation, and reference statistics. Rather than using tables and charts to display use data, a geographic information system (GIS) facilitates a more visually appealing graphical display of the data in the form of a map. GISs have been used by library and information science (LIS) researchers and practitioners to create maps that display analyses of service area populations and demographics, facilities space management issues, spatial distribution of in-library use of materials, planned branch consolidations, and so on. The “seating sweeps” method allows researchers and librarians to collect in-library use data regarding where patrons are locating themselves within the library and what they are doing at those locations, such as sitting and reading, studying in a group, or socializing. This paper proposes a GIS as a tool to visually display in-library use data collected via “seating sweeps” of a library. By using a GIS to store, manage, and display the data, researchers and librarians can create visually appealing maps that show areas of heavy use and evidence of the use and value of the library for a community. Example maps are included to facilitate the reader’s understanding of the possibilities afforded by using GISs in LIS research.
Reducing Psychological Resistance to Digital Repositories
Authors: Quinn Brian 
Published: February 2013

The potential value of digital repositories is dependent on the cooperation of scholars to deposit their work. Although many researchers have been resistant to submitting their work, the literature on digital repositories contains very little research on the psychology of resistance. This article looks at the psychological literature on resistance and explores what its implications might be for reducing the resistance of scholars to submitting their work to digital repositories. Psychologists have devised many potentially useful strategies for reducing resistance that might be used to address the problem; this article examines these strategies and how they might be applied.
Generating Collaborative Systems for Digital Libraries: a Model-Driven Approach
Authors: Malizia Alessio , Bottoni Paolo , Levialdi S. 
Published: February 2013

The design and development of a digital library involves different stakeholders, such as: information architects, librarians, and domain experts, who need to agree on a common language to describe, discuss, and negotiate the services the library has to offer. To this end, high-level, language-neutral models have to be devised. Metamodeling techniques favor the definition of domainspecific visual languages through which stakeholders can share their views and directly manipulate representations of the domain entities. This paper describes CRADLE (Cooperative-Relational Approach to Digital Library Environments), a metamodel-based framework and visual language for the definition of notions and services related to the development of digital libraries. A collection of tools allows the automatic generation of several services, defined with the CRADLE visual language, and of the graphical user interfaces providing access to them for the final user. The effectiveness of the approach is illustrated by presenting digital libraries generated with CRADLE, while the CRADLE environment has been evaluated by using the cognitive dimensions framework.

Bridging the Gap: Self-Directed Staff Technology Training
Authors: Quinney Kayla L. , Smith Sara D. , Galbraith Quinn 
Published: February 2013

Undergraduates, as members of the Millennial Generation, are proficient in Web 2.0 technology and expect to apply these technologies to their coursework—including scholarly research. To remain relevant, academic libraries need to provide the technology that student patrons expect, and academic librarians need to learn and use these technologies themselves. Because leaders at the Harold B. Lee Library of Brigham Young University (HBLL) perceived a gap in technology use between students and their staff and faculty, they developed and implemented the Technology Challenge, a self-directed technology training program that rewarded employees for exploring technology daily. The purpose of this paper is to examine the Technology Challenge through an analysis of results of surveys given to participants before and after the Technology Challenge was implemented. The program will also be evaluated in terms of the adult learning theories of andragogy and selfdirected learning. HBLL found that a self-directed approach fosters technology skills that librarians need to best serve students. In addition, it promotes lifelong learning habits to keep abreast of emerging technologies. This paper offers some insights and methods that could be applied in other libraries, the most valuable of which is the use of self-directed and andragogical training methods to help academic libraries better integrate modern technologies.
Next-Generation Library Catalogs and the Problem of Slow Response Time
Authors: Brown-Sica Margaret , Beall Jeffrey , McHale Nina 
Published: February 2013

Response time as defined for this study is the time that it takes for all files that constitute a single webpage to travel across the Internet from a Web server to the end user’s browser. In this study, the authors tested response times on queries for identical items in five different library catalogs, one of them a next-generation (NextGen) catalog. The authors also discuss acceptable response time and how it may affect the discovery process. They suggest that librarians and vendors should develop standards for acceptable response time and use it in the product selection and development processes.
