Authors : Sahar Vahdati, Guillermo Palma, Rahul Jyoti Nath, Christoph Lange, Sören Auer, Maria-Esther Vidal

Knowledge graphs represent the meaning of properties of real-world entities and relationships among them in a natural way. Exploiting semantics encoded in knowledge graphs enables the implementation of knowledge-driven tasks such as semantic retrieval, query processing, and question answering, as well as solutions to knowledge discovery tasks including pattern discovery and link prediction.

In this paper, we tackle the problem of knowledge discovery in scholarly knowledge graphs, i.e., graphs that integrate scholarly data, and present Korona, a knowledge-driven framework able to unveil scholarly communities for the prediction of scholarly networks.

Korona implements a graph partition approach and relies on semantic similarity measures to determine relatedness between scholarly entities. As a proof of concept, we built a scholarly knowledge graph with data from researchers, conferences, and papers of the Semantic Web area, and apply Korona to uncover co-authorship networks.

Results observed from our empirical evaluation suggest that exploiting semantics in scholarly knowledge graphs enables the identification of previously unknown relations between researchers.

By extending the ontology, these observations can be generalized to other scholarly entities, e.g., articles or institutions, for the prediction of other scholarly patterns, e.g., co-citations or academic collaboration.

Open Education Science

Posté le par

Authors : Tim van der Zee, Justin Reich

Scientific progress is built on research that is reliable, accurate, and verifiable. The methods and evidentiary reasoning that underlie scientific claims must be available for scrutiny.

Like other fields, the education sciences suffer from problems such as failure to replicate, validity and generalization issues, publication bias, and high costs of access to publications—all of which are symptoms of a nontransparent approach to research. Each aspect of the scientific cycle—research design, data collection, analysis, and publication—can and should be made more transparent and accessible.

Open Education Science is a set of practices designed to increase the transparency of evidentiary reasoning and access to scientific research in a domain characterized by diverse disciplinary traditions and a commitment to impact in policy and practice.

Transparency and accessibility are functional imperatives that come with many benefits for the individual researcher, scientific community, and society at large—Open Education Science is the way forward.

Scholarly Communication Librarians’ Relationship with Research Impact Indicators: An Analysis of a National Survey of Academic Librarians in the United States

Posté le par

Authors: Rachel Ann Miles, Stacy Konkiel, Sarah Sutton

INTRODUCTION

Academic librarians, especially in the field of scholarly communication, are often expected to understand and engage with research impact indicators. However, much of the current literature speculates about how academic librarians are using and implementing research impact indicators in their practice.

METHODS

This study analyzed the results from a 2015 survey administered to over 13,000 academic librarians at Carnegie-classified R1 institutions in the United States. The survey concentrated on academic librarians’ familiarity with and usage of research impact indicators.

RESULTS

This study uncovered findings related to academic librarians’ various levels of familiarity with research impact indicators and how they implement and use research impact indicators in their professional development and in their library job duties.

DISCUSSION

In general, academic librarians with regular scholarly communication support duties tend to have higher levels of familiarity of research impact indicators. In general, academic librarians are most familiar with the citation counts and usage statistics and least familiar with altmetrics.

During consultations with faculty, the Journal Impact Factor (JIF) and citation counts are more likely to be addressed than the author h-index, altmetrics, qualitative measures, and expert peer reviews.

The survey results also hint towards a growing interest in altmetrics among academic librarians for their professional advancement.

CONCLUSION

Academic librarians are continually challenged to keep pace with the changing landscape of research impact metrics and research assessment models. By keeping pace and implementing research impact indicators in their own practices, academic librarians can provide a crucial service to the wider academic community.

Challenges of Adopting Open Educational Resources (OER) in Kenyan Secondary Schools: The Case of Open Resources for English Language Teaching (ORELT)

Authors : Daniel Ochieng Orwenjo, Fridah Kanana Erastus

Kenya, like many African countries, has faced enormous challenges in the production of and access to quality relevant teaching and learning materials and resources in her primary and secondary school classrooms.

This has been occasioned by a plethora of factors which include, but are not limited to a lack of finances, tradition, competence, and experience to develop such resources. Such a situation has persisted despite the existence and availability of many Open Educational Resources (OERs) that have been developed by many education stakeholders at enormous costs.

Such freely available resources could potentially improve the quality of existing resources or help to develop new courses. Yet, their uptake and reuse in secondary and primary schools in Kenya continues to be very low. This paper reports the findings of a study in which Open Resources for English Language Teaching (ORELT) developed by the Commonwealth of Learning (COL), Canada, were piloted in sampled fifty (50) Kenyan secondary schools.

The study applied the Model 1 – Distance and Dependence (Zhao et al 2002) model to investigate the challenges that hinder instructors to adopt and use ORELT materials. The study reported that poor infrastructure, negative attitudes, lack of ICT competencies, and other skill gaps among teachers and lack of administrative support are some of the implementation challenges that have continued to dog the implementation, adoption and use of OERs in Kenyan schools.

The findings of the present study will go a long way in providing useful insights to the developers of OERs and Kenyan education stakeholders in devising strategies of maximum utilisation of OERs in the Kenyan school system.

There has been tremendous growth in the amount of digital content created by libraries, publishers, cultural institutions and the general public. While there are great benefits to having content available in digital form, digital objects can be extremely short-lived unless proper attention is paid to preservation.

Reflecting on our experience with the digital preservation service Portico, we provide background on Portico’s history and evolving practice of sustainable preservation of the digital artifacts of scholarly communications.

We also provide an overview of the digital preservation landscape as we see it now, with some thoughts on current requirements for preservation, and thoughts on the opportunities and challenges that lie ahead.

The Modern Research Data Portal: a design pattern for networked, data-intensive science

Authors : Kyle Chard, Eli Dart, Ian Foster​, David Shifflett, Steven Tuecke, Jason Williams

We describe best practices for providing convenient, high-speed, secure access to large data via research data portals. We capture these best practices in a new design pattern, the Modern Research Data Portal, that disaggregates the traditional monolithic web-based data portal to achieve orders-of-magnitude increases in data transfer performance, support new deployment architectures that decouple control logic from data storage, and reduce development and operations costs.

We introduce the design pattern; explain how it leverages high-performance data enclaves and cloud-based data management services; review representative examples at research laboratories and universities, including both experimental facilities and supercomputer sites; describe how to leverage Python APIs for authentication, authorization, data transfer, and data sharing; and use coding examples to demonstrate how these APIs can be used to implement a range of research data portal capabilities.

Sample code at a companion web site, https://docs.globus.org/mrdp, provides application skeletons that readers can adapt to realize their own research data portals.

Data in the life sciences are extremely diverse and are stored in a broad spectrum of repositories ranging from those designed for particular data types (such as KEGG for pathway data or UniProt for protein data) to those that are general-purpose (such as FigShare, Zenodo, Dataverse or EUDAT).

These data have widely different levels of sensitivity and security considerations. For example, clinical observations about genetic mutations in patients are highly sensitive, while observations of species diversity are generally not.

The lack of uniformity in data models from one repository to another, and in the richness and availability of metadata descriptions, makes integration and analysis of these data a manual, time-consuming task with no scalability.

Here we explore a set of resource-oriented Web design patterns for data discovery, accessibility, transformation, and integration that can be implemented by any general- or special-purpose repository as a means to assist users in finding and reusing their data holdings.

We show that by using off-the-shelf technologies, interoperability can be achieved atthe level of an individual spreadsheet cell. We note that the behaviours of this architecture compare favourably to the desiderata defined by the FAIR Data Principles, and can therefore represent an exemplar implementation of those principles.

The proposed interoperability design patterns may be used to improve discovery and integration of both new and legacy data, maximizing the utility of all scholarly outputs.
