Big data for monitoring educational systems
This report considers âhow advances in big data are likely to transform the context and methodology of monitoring educational systems within a long-term perspective (10-30 years) and impact the evidence based policy development in the sectorâ, big data are âlarge amounts of different types of data produced with high velocity from a high number of various types of sources.â Five independent experts were commissioned by Ecorys, responding to themes of: students' privacy, educational equity and efficiency, student tracking, assessment and skills. The experts were asked to consider the âmacro perspective on governance on educational systems at all levels from primary, secondary education and tertiary â the latter covering all aspects of tertiary from further, to higher, and to VETâ, prioritising primary and secondary levels of education
Social media and public policy
Introduction: Government and public service delivery is taking place in a changed world. A significant level of social, economic and political activity is now happening on the internet.As people buy and sell goods, search for information, browse the web and share their dayâtoâday experiences with colleagues, friends and family through social networks, they produce an enormous amount of data.The use of this data to develop insights is growing rapidly. In the private sector it is being used to enhance decision making, understand customer behaviour, improve operational efficiency and identify new markets.The new information environment also obliges government to develop new capabilities to understand the information available and to compete for attention and influence within it.Part of the challenge in embracing the digital age is that, in the midst of rapid change, itâs very difficult to know where to place your bets. We do not yet know exactly what access to large volumes of social data will mean for our society. It certainly will not present a panacea for longâstanding social problems; but it can add another dimension to our understanding of them.This report considers whether social media data can improve the quality and timeliness of the evidence base that informs public policy. Can the myriad of human connections and interactions on the web provide insight to enable government to develop better policy, understand its subsequent impact and inform the many different organisations that deliver public services?The report is based on an evaluation of available literature and interviews with 25 experts from a number of disciplines. Given that developments in this field are at such an early stage, it aims to provide helpful signposts rather than definitive answers
AAPOR Report on Big Data
In recent years we have seen an increase in the amount of statistics in society describing different phenomena based on so called Big Data. The term Big Data is used for a variety of data as explained in the report, many of them characterized not just by their large volume, but also by their variety and velocity, the organic way in which they are created, and the new types of processes needed to analyze them and make inference from them. The change in the nature of the new types of data, their availability, the way in which they are collected, and disseminated are fundamental. The change constitutes a paradigm shift for survey research.There is a great potential in Big Data but there are some fundamental challenges that have to be resolved before its full potential can be realized. In this report we give examples of different types of Big Data and their potential for survey research. We also describe the Big Data process and discuss its main challenges
Mobile Privacy and Business-to-Platform Dependencies: An Analysis of SEC Disclosures
This Article systematically examines the dependence of mobile apps on mobile platforms for the collection and use of personal information through an analysis of Securities and Exchange Commission (SEC) filings of mobile app companies. The Article uses these disclosures to find systematic evidence of how app business models are shaped by the governance of user data by mobile platforms, in order to reflect on the role of platforms in privacy regulation more generally. The analysis of SEC filings documented in the Article produces new and unique insights into the data practices and data-related aspects of the business models of popular mobile apps and shows the value of SEC filings for privacy law and policy research more generally. The discussion of SEC filings and privacy builds on regulatory developments in SEC disclosures and cybersecurity of the last decade. The Article also connects to recent regulatory developments in the U.S. and Europe, including the General Data Protection Regulation, the proposals for a new ePrivacy Regulation and a Regulation of fairness in business-to-platform relations
Knowledge will Propel Machine Understanding of Content: Extrapolating from Current Examples
Machine Learning has been a big success story during the AI resurgence. One
particular stand out success relates to learning from a massive amount of data.
In spite of early assertions of the unreasonable effectiveness of data, there
is increasing recognition for utilizing knowledge whenever it is available or
can be created purposefully. In this paper, we discuss the indispensable role
of knowledge for deeper understanding of content where (i) large amounts of
training data are unavailable, (ii) the objects to be recognized are complex,
(e.g., implicit entities and highly subjective content), and (iii) applications
need to use complementary or related data in multiple modalities/media. What
brings us to the cusp of rapid progress is our ability to (a) create relevant
and reliable knowledge and (b) carefully exploit knowledge to enhance ML/NLP
techniques. Using diverse examples, we seek to foretell unprecedented progress
in our ability for deeper understanding and exploitation of multimodal data and
continued incorporation of knowledge in learning techniques.Comment: Pre-print of the paper accepted at 2017 IEEE/WIC/ACM International
