Wikipedia in higher education: Changes in perceived value through content contribution

Posted on by Hans Dillaerts

Authors : Joan Soler-Adillon, Dragana Pavlovic

Wikipedia is a widely used resource by university students, but it is not necessarily regarded as being reliable and trustworthy by them, nor is it seen as a context in which to make content contributions.

This paper presents a teaching and research project that consisted in having students edit or create Wikipedia articles and testing whether or not this experience changed their perceived value of the platform. We conducted our experience at Universitat Pompeu Fabra (Barcelona, Spain) and University of Niš (Niš, Serbia) with a total number of 240 students.

These students edited articles and answered two questionnaires, one before and one after the exercise. We compared the pre and post experience answers to the questionnaires with a series of paired samples ttests, through which our data showed that students did significantly change their perception of reliability and usefulness, and of likeliness of finding false information on Wikipedia.

Their appreciation of the task of writing Wikipedia articles, in terms of it being interesting and challenge also increased. They did not significantly change, however, their judgement on the social value of the platform, neither in the university nor in the general context.

In addition, the open questions and informal feedback allowed us to gather valuable insights towards the evaluation of the overall experience.

How Many More Cites is a $3,000 Open Access Fee Buying You? Empirical Evidence from a Natural Experiment

Posted on by Hans Dillaerts

Authors :  Frank Mueller-Langer, Richard Watt

This paper analyzes the effect of open access (OA) status of published journal articles on peer recognition, as measured by the number of citations. Using cross-sectional and panel data from interdisciplinary mathematics and economics journals, we perform negative binomial, Poisson and linear regressions together with generalized method of moments/instrumental variable methods regressions.

We benefit from a natural experiment via hybrid OA pilot agreements. Under these agreements, OA status is exogenously assigned to all articles of authors affiliated with hybrid OA pilot institutions.

Our cross-sectional analysis of the full sample suggests that there is no citation benefit associated with hybrid OA. In contrast, for the subpopulation of journal articles for which neither OA pre-prints nor OA post-prints are available, we find positive hybrid OA effects for the full sample and each discipline separately.

We address the issue of selection bias by exploiting a panel of journal articles for which OA pre-prints are available. Citations to pre-prints allow us to identify the intrinsic quality of articles prior to publication in a journal.

The results from the panel analysis provide additional empirical evidence for a negligible hybrid OA citation effect.

DataMed – an open source discovery index for finding biomedical datasets

Posted on by Hans Dillaerts

Authors : Xiaoling Chen, Anupama E Gururaj, Burak Ozyurt, Ruiling Liu, Ergin Soysal, Trevor Cohen, Firat Tiryaki, Yueling Li, Nansu Zong, Min Jiang, Deevakar Rogith, Mandana Salimi, Hyeon-eui Kim, Philippe Rocca-Serra, Alejandra Gonzalez-Beltran, Claudiu Farcas, Todd Johnson, Ron Margolis, George Alter, Susanna-Assunta Sansone, Ian M Fore, Lucila Ohno-Machado, Jeffrey S Grethe, Hua Xu

Objective

Finding relevant datasets is important for promoting data reuse in the biomedical domain, but it is challenging given the volume and complexity of biomedical data. Here we describe the development of an open source biomedical data discovery system called DataMed, with the goal of promoting the building of additional data indexes in the biomedical domain.

Materials and Methods

DataMed, which can efficiently index and search diverse types of biomedical datasets across repositories, is developed through the National Institutes of Health–funded biomedical and healthCAre Data Discovery Index Ecosystem (bioCADDIE) consortium.

It consists of 2 main components: (1) a data ingestion pipeline that collects and transforms original metadata information to a unified metadata model, called DatA Tag Suite (DATS), and (2) a search engine that finds relevant datasets based on user-entered queries.

In addition to describing its architecture and techniques, we evaluated individual components within DataMed, including the accuracy of the ingestion pipeline, the prevalence of the DATS model across repositories, and the overall performance of the dataset retrieval engine.

Results and Conclusion

Our manual review shows that the ingestion pipeline could achieve an accuracy of 90% and core elements of DATS had varied frequency across repositories. On a manually curated benchmark dataset, the DataMed search engine achieved an inferred average precision of 0.2033 and a precision at 10 (P@10, the number of relevant results in the top 10 search results) of 0.6022, by implementing advanced natural language processing and terminology services.

Currently, we have made the DataMed system publically available as an open source package for the biomedical community.

Open Access and the Theological Imagination

Posted on by Hans Dillaerts

Authors : Talea Anderson, David Squires

The past twenty years have witnessed a mounting crisis in academic publishing. Companies such as Reed-Elsevier, Wiley-Blackwell, and Taylor and Francis have earned unprecedented profits by controlling more and more scholarly output while increasing subscription rates to academic journals.

Thus publishers have consolidated their influence despite widespread hopes that digital platforms would disperse control over knowledge production. Open access initiatives dating back to the mid-1990s evidence a religious zeal for overcoming corporate interests in academic publishing, with key advocates branding their efforts as archivangelism.

Little attention has been given to the legacy or implications of religious rhetoric in open access debates despite its increasing pitch in recent years. This essay shows how the Protestant imaginary reconciles–rather than opposes–open access initiatives with market economics by tracing the rhetoric of openness to free-market liberalism.

Working against the tendency to accept the Reformation as an analogy for the relationship between knowledge production, publishers, and academics, we read Protestantism as a counterproductive element of the archivangelist inheritance.

Autorité scientifique et épistémique à l’épreuve de la mesure des citations

Posted on by Hans Dillaerts

Auteur/Author : Evelyne Broudoux

Cet article est basé sur une communication donnée le 18 mars 2016 à l’occasion du Colloque « Médiations informatisées de l’autorité : nouvelles écritures, nouvelles pratiques de la reconnaissance ? », organisé à l’ISCC par le Gripic/Celsa.

Cet article fait le point sur la construction de l’autorité scientifique dans la communication scientifique en examinant sous l’angle du repérage des autorités épistémique et scientifique : le champ social des disciplines scientifiques, les études réalisées autour de l’analyse des citations et ses mesures, l’usage croissant du web social et l’auto-référence, la sémantisation des citations.

L’objectif étant de regarder les enjeux actualisés de la communication scientifique.

Open Access Determinants and the Effect on Article Performance

Posted on by Hans Dillaerts

Author : Sumiko Asai

Although open access has steadily developed with the continuous increase in subscription journal price, the effect of open access articles on citations remains a controversial issue. The present study empirically examines the factors determining authors’ choice to provide open access and the effects of open access on downloads and citations in hybrid journals.

This study estimates author’s choice of open access using a probit model, and the results show that the cost of open access is an important factor in the decision. After a test for endogeneity of open access choice, the equation for downloads is estimated with the variables representing characteristics of articles and authors.

The results of estimating downloads by ordinary least squares show that open access increases the number of downloads in hybrid journals. On the other hand, from citation estimations using a negative binominal model, this study found that the effect of open access on the number of citations differs among hybrid journals.

It is a good practice for authors to consider a balance between article processing charges and the benefits that will be gained from open access when deciding whether to provide open access.
