Wikipedia: the difference between information acquisition and learning knowledge

Posted on by Hans Dillaerts

This paper attempts to define Wikipedia in an information literacy context by providing an analysis of learning knowledge and Wikipedia’s structure. The distribution of learning in the digital information age is a core topic for scholarly communication. It is highly relevant to students, citizens and instructors in their roles as users of content and as creators of content.

Even though it appears to be far removed from traditional publishing in the print world, many students, citizens and instructors use digital information tools to share aspects of their works in a way that is defined as publishing. Understanding the difference between information acquisition and learning knowledge are essential in educational settings.

Semantic representation of scientific literature: bringing claims, contributions and named entities onto the Linked Open Data cloud

Posted on by Hans Dillaerts

Motivation

Finding relevant scientific literature is one of the essential tasks researchers are facing on a daily basis. Digital libraries and web information retrieval techniques provide rapid access to a vast amount of scientific literature. However, no further automated support is available that would enable fine-grained access to the knowledge ‘stored’ in these documents. The emerging domain of Semantic Publishing aims at making scientific knowledge accessible to both humans and machines, by adding semantic annotations to content, such as a publication’s contributions, methods, or application domains.

However, despite the promises of better knowledge access, the manual annotation of existing research literature is prohibitively expensive for wide-spread adoption. We argue that a novel combination of three distinct methods can significantly advance this vision in a fully-automated way: (i) Natural Language Processing (NLP) for Rhetorical Entity (RE) detection; (ii) Named Entity (NE) recognition based on the Linked Open Data (LOD) cloud; and (iii) automatic knowledge base construction for both NEs and REs using semantic web ontologies that interconnect entities in documents with the machine-readable LOD cloud.

Results

We present a complete workflow to transform scientific literature into a semantic knowledge base, based on the W3C standards RDF and RDFS. A text mining pipeline, implemented based on the GATE framework, automatically extracts rhetorical entities of type Claims and Contributions from full-text scientific literature. These REs are further enriched with named entities, represented as URIs to the linked open data cloud, by integrating the DBpedia Spotlight tool into our workflow.

Text mining results are stored in a knowledge base through a flexible export process that provides for a dynamic mapping of semantic annotations to LOD vocabularies through rules stored in the knowledge base. We created a gold standard corpus from computer science conference proceedings and journal articles, where Claim and Contribution sentences are manually annotated with their respective types using LOD URIs. The performance of the RE detection phase is evaluated against this corpus, where it achieves an average F-measure of 0.73. We further demonstrate a number of semantic queries that show how the generated knowledge base can provide support for numerous use cases in managing scientific literature.

Donor Funded Open Educational Resources: Making the Case

Posted on by Hans Dillaerts

PURPOSE

This paper aims to explain the concept of Open Educational Resources (OER) and how libraries can make a good case to donors to fund these types of projects.

DESIGN/METHODOLOGY/APPROACH

The literature reveals that donors have been willing to support projects that save students money on textbooks. Course reserves have traditionally been a popular model. More recently, libraries have found funding for OER initiatives. These types of initiatives are discussed and several case studies of donors currently funding OER projects are examined.

FINDINGS

Donors, internal and external to the library and to the university, have shown an interest in funding projects that reduce textbook costs for students. They have funded course reserves in the past and have begun to fund OER projects. There are both qualitative and quantitative methods to induce donors to fund these types of projects.

PRACTICAL IMPLICATIONS

Libraries have traditionally supported the mission of access to information and for academic libraries that has sometimes included access to textbooks. Course reserves are a limited solution, whereas when an OER replaces an expensive textbook, it is a viable solution for all students.

SOCIAL IMPLICATIONS

OERs have strong social implications. Any person, whether associated with an institution of higher learning, or not, can access the information in an OER and learn the associated content.

ORIGINALITY/VALUE

There is some literature on specific OER projects. This paper aims to fill a gap in the literature, specifically on how to approach donors regarding OER initiatives.

Science bloggers’ self-perceived communication roles

Posted on by Hans Dillaerts

This study addresses an open question about science bloggers’ self-perceived roles as science communicators. Previous research has investigated the roles science journalists see themselves engaging in, but such research has failed to capture the experiences of science bloggers as a broad and diverse group that is yet often very different in their practices from professional journalists.

In this study, a survey of over 600 science bloggers reveals that on the broadest level, science bloggers see themselves engaging most often as explainers of science and public intellectuals. Perceived communication role depends predominantly on occupation, science communication training, blog affiliation and gender.

Open Scholarship Practices Reshaping South Africa’s Scholarly Publishing Roadmap

Posted on by Hans Dillaerts

South African higher education institutions are the largest producers of research output on the African continent. Given this status, South African researchers have a moral obligation to share their research output with the rest of the continent via a medium that minimizes challenges of access; open scholarship is that medium. The majority of South African higher education libraries provide an open access publishing service. However, in most of these cases this service is via engagement with the green open access route, that is, institutional repositories (IR).

Some of the libraries have piloted and adopted gold open access services such as publishing of “diamond” gold open access journals and supporting article processing charges. The experiment with publishing open monographs is a new venture. This venture must be viewed against the backdrop of the need for open educational resources (OERs). OER is an area that is very much in a fledgling stage and is gaining traction, albeit, at a slow pace.

The growth of IRs, the growth in support for gold open access including the library acting as a publisher, the experimentation with open monographs, and OERs are all shaping South Africa’s scholarly publishing roadmap.

Considering Non-Open Access Publication Charges in the “Total Cost of Publication”

Posted on by Hans Dillaerts

Recent research has tried to calculate the “total cost of publication” in the British academic sector, bringing together the costs of journal subscriptions, the article processing charges (APCs) paid to publish open-access content, and the indirect costs of handling open-access mandates. This study adds an estimate for the other publication charges (predominantly page and colour charges) currently paid by research institutions, a significant element which has been neglected by recent studies.

When these charges are included in the calculation, the total cost to institutions as of 2013/14 is around 18.5% over and above the cost of journal subscriptions—11% from APCs, 5.5% from indirect costs, and 2% from other publication charges. For the British academic sector as a whole, this represents a total cost of publication around £213 million against a conservatively estimated journal spend of £180 million, with non-APC publication charges representing around £3.6 million.

A case study is presented to show that these costs may be unexpectedly high for individual institutions, depending on disciplinary focus. The feasibility of collecting this data on a widespread basis is discussed, along with the possibility of using it to inform future subscription negotiations with publishers.

The Challenges of Journal Startup in the Digital Era

Posted on by Hans Dillaerts

This paper aims to contribute to the evolving literature on the new landscape of scholarly journals. It builds on a series of experiences as a journal editor which span the print and digital eras, and focuses on two current activities with new journals.

One was designed as a synoptic journal in a broad multidisciplinary field, supported by a commercial publisher; the other a non-revenue journal which aims to showcase the work of undergraduates in the author’s institution. Despite the uniqueness of goals and delivery, some of the experiences—and challenges—have proved remarkably similar.
