Promoting International Interoperability of Research Information Systems: VIVO and CERIF
No full textInstitutional repositories (IR) and Current Research Information Systems (CRIS) store and manage information on the context in which research activity takes place. Several models, standards and ontologies have been proposed to date as solutions to provide coherent semantic descriptions of research information. These present a large degree of overlap but also present very different approaches to modelling. This paper introduces a contrast of two of the more widespread models, the VIVO ontology and the CERIF standards, and provides guidance for mapping them in a way that enables clients to integrate data coming from heterogeneous sources. The majority of mapping challenges have risen from the representation of VIVO sub-hierarchies in CERIF as well as from the representation of CERIF attributes in VIVO. In addition, the paper illustrates features for linking data across the Web, for querying of geographically distributed data stores and for aggregating data described using different data models in a common store. These features are supported by semantic web technologies including RDF, OWL and SWRL
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The GlobalAccess2.info Portal: A Flexible Technology for Managing Journal Access Information
Get PDFContributing institutions: Cornell University; Albert R. Mann LibraryWeb-based portals bring together information from many sources and add value to that information by providing a single browsing interface and more consistent display of individual content items. However, designing a portal has typically required developers to pick one or two primary organizing facets at the expense of other valid ones or else face maintenance-intensive cross-referencing between different views of the same information. A new general-purpose portal technology developed at Mann Library offers greater flexibility for coordinating multiple modes of access to information. Developed originally for the VIVO virtual life science library at Cornell (http://vivo.library.cornell.edu), the Vitro portal technology leverages a flexible ontology structure to link related information and deliver multiple facets or views to a top-level interface. Individual records display in a richly cross-linked structure designed to optimize context for the user while highlighting the original resources gathered together in the portal. The new http://globalaccess2.info portal provides a common Web presence for a consortium of international programs than provide free or reduced cost access to scholarly journals for developing countries, including AGORA, eIFL, HINARI, INASP, and TEEAL. Resources are equally discoverable by country, by program, by donor agency, by publisher, and by topic area, meeting the needs of diverse users including librarians in the developing world who are potential program participants, staff at the programs themselves, donor agencies, publishers reviewing availability of their own and other services, and librarians in the developing world who have partners in developing countries. A free-text search facility brings up individual entries along with any relevant donor, publisher, program, or country information, allowing users to navigate via multiple independent paths depending on their needs. Detailed content listings at the individual journal level are maintained on the program's own Web sites and linked at the page level from the common portal.
Over the last 7 months the system that supports both globalaccess2.info and VIVO has been rewritten to promote maintainability and with the hope of releasing the source for use by other institutions. The system is written in Java and runs on the Apache Tomcat servlet container. MySQL is used for back end storage and Lucene is used for full text indexing
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
