    This paper is written for (social science) researchers seeking to analyze the wealth of social media now available. It presents a comprehensive review of software tools for social networking media, wikis, really simple syndication feeds, blogs, newsgroups, chat and news feeds. For completeness, it also includes introductions to social media scraping, storage, data cleaning and sentiment analysis. Although principally a review, the paper also provides a methodology and a critique of social media tools. Analyzing social media, in particular Twitter feeds for sentiment analysis, has become a major research and business activity due to the availability of web-based application programming interfaces (APIs) provided by Twitter, Facebook and News services. This has led to an ‘explosion’ of data services, software tools for scraping and analysis and social media analytics platforms. It is also a research area undergoing rapid change and evolution due to commercial pressures and the potential for using social media data for computational (social science) research. Using a simple taxonomy, this paper provides a review of leading software tools and how to use them to scrape, cleanse and analyze the spectrum of social media. In addition, it discussed the requirement of an experimental computational environment for social media research and presents as an illustration the system architecture of a social media (analytics) platform built by University College London. The principal contribution of this paper is to provide an overview (including code fragments) for scientists seeking to utilize social media scraping and analytics either in their research or business. The data retrieval techniques that are presented in this paper are valid at the time of writing this paper (June 2014), but they are subject to change since social media data scraping APIs are rapidly changing

    Towards A Taxonomy of Emerging Topics in Open Government Data: A Bibliometric Mapping Approach

    Get PDF
    The purpose of this paper is to capture the emerging research topics in Open Government Data (OGD) through a bibliometric mapping approach. Previous OGD research has covered the evolution of the discipline with the application of bibliometric mapping tools. However, none of these studies have extended the bibliometric mapping approach for taxonomy building. Realizing this potential, we used a bibliometric tool to perform keyword analysis as a foundation for taxonomy construction. A set of keyword clusters was constructed, and qualitative analysis software was used for taxonomy creation. Emerging topics were identified in a taxonomy form. This study contributes towards the development of an OGD taxonomy. This study contributes to the procedural realignment of a past study by incorporating taxonomy building elements for taxonomy creation. These contributions are significant because there is insufficient taxonomy research in the OGD discipline. The taxonomy building procedures extended in this study are applicable to other fields

    Public policy: turning open data into democratic data - Portal Quality Assessment - Comparative Analysis

    Get PDF
    Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Knowledge Management and Business IntelligenceAs data, information, and their respective provisioning gets more and more ubiquitous, people start to look for - and even demand - transparency and data to support the policies in effect right now that, either directly or indirectly, affects them. There are many expectations related with Open Government Data initiatives, such as improving policymaking, increase in transparency of government spending, advance citizen engagement with the institutions, etc. This master’s proposal aims to offer research that pertains to this theme; including an in depth look into one of the most reputed OGD maturity report (EU Open Data Maturity Report), a systematic literature review of Open Data’s main objectives and goals, the influence on publication of scientific literature as well as the potential socio-economic and transparency impact they may have, in order to proceed to an assessment of the portal quality in Portugal by evaluating the usage of its data on scientific papers and articles; through the usage of bibliometrics and PRISMA methodology. My thesis research drills down on these topics: What are the most used Portuguese OGD portals in academic literature? What are the authors that make the most use of Portuguese OGD portals? What characterizes the authors and the publications

    Geospatial data analysis in Russia’s geoweb

    Get PDF
    The chapter examines the role of geospatial data in Russia’s online ecosystem. Facilitated by the rise of geographic information systems and user-generated content, the distribution of geospatial data has blurred the line between physical spaces and their virtual representations. The chapter discusses different sources of these data available for Digital Russian Studies (e.g., social data and crowdsourced databases) together with the novel techniques for extracting geolocation from various data formats (e.g., textual documents and images). It also scrutinizes different ways of using these data, varying from mapping the spatial distribution of social and political phenomena to investigating the use of geotag data for cultural practices’ digitization to exploring the use of geoweb for narrating individual and collective identities online

    Big Data Research in Italy: A Perspective
