We need more carrots: give academic researchers the support and incentives to share data

Making data available for other researchers to find, use, reuse, and reproduce is fundamental to open science, and ultimately makes research more efficient and effective. Yet despite funder policies that encourage and require data sharing, researchers in both the UK and the US report lower percentages of data sharing than the global average. In addition to progressive policies, Grace Baynes […]

Student data systems and GovTech apps will increase competition and performance measurement in higher education

Current debates in higher education policy have drawn attention to the significant impacts of marketisation, metrics, and performance management on the sector. Ben Williamson argues that a restructuring of the data infrastructure is shaping these HE trends. An examination of the HE data infrastructure reveals the political aspirations coded into its architecture, the actors involved in its production, and its […]

What a fossil revolution reveals about the history of “big data”

Improved technologies have allowed faster and more powerful statistical analysis and changed how we “see” data. It’s now taken for granted that the best way to understand large, complex phenomena is by crunching the numbers via computers and projecting the results as visual summaries. To David Sepkoski, that’s not a bad thing, but it does pose some challenges. The complexity […]

How people feel about what companies do with their data is just as important as what they know about it

The recent revelation that Cambridge Analytica was able to acquire the Facebook data of 50 million people has led to a surge of interest and questions around what companies do with people’s data. Amidst all of this, little attention has been paid to the feelings of those whose data are used, shared, and acted upon. According to Helen Kennedy, more […]

Releasing 1.8 million open access publications from publisher systems for text and data mining

Text and data mining offers an opportunity to improve the way we access and analyse the outputs of academic research. But the technical infrastructure of the current scholarly communication system is not yet ready to support TDM to its full potential, even for open access outputs. To address this problem, Petr Knoth, Nancy Pontika and Lucas Anastasiou have developed the […]

What factors do scientists perceive as promoting or hindering scientific data reuse?

Increased calls for data sharing have formed part of many governments’ agendas to boost innovation and scientific development. Data openness for reuse also resonates with the recognised need for more transparent, reproducible science. But what are scientists’ perceptions about data reuse? Renata Gonçalves Curty, Kevin Crowston, Alison Specht, Bruce W. Grant and Elizabeth D. Dalton make use of existing survey […]

Without urgent action big and open data may widen existing inequalities and social divides

The juncture of big and open data informs areas as diverse as artificial intelligence, agriculture, and public health, and promises to transform our ability to tackle global challenges. However, Sabina Leonelli highlights three major concerns over how big and open data are currently managed: the unsustainable nature of the digital data landscape; the quality and credibility of the data themselves; […]

An emerging iron cage? Understanding the risks of increased use of big data applications in social policy

Big data technologies are increasingly being utilised in the field of social policy. Although big data methods and strategies are often preferred as a form of evidence-based policy development, big data techniques do not necessarily guarantee scientific objectivity. Hamish Robertson and Joanne Travaglia discuss concerns about the rapid growth in big data methods being used to inform and shape social […]

More data or better data? Using statistical decision theory to guide data collection

When designing data collection, researchers must take important decisions on how much data to collect and what resources to devote to enhancing the quality of the collected data. But the threshold for choosing better over bigger data may be reached long before the sample numbers in the thousands, write Jeff Dominitz and Charles F. Manski. Big data has become an […]

Book Review: Open Data and the Knowledge Society by Bridgette Wessels, Kush Wadhwa, Rachel L. Finn and Thordis Sveinsdottir

In Open Data and the Knowledge Society, authors Bridgette Wessels, Kush Wadhwa, Rachel L. Finn and Thordis Sveinsdottir place the management of open data ecosystems at the heart of the transformation into a “knowledge society”, presenting five case studies through which to consider various ways of dealing with different types of data. Miranda Nell welcomes this book for showing how open data is […]
