  • Social Data Biases and Methodological Pitfalls
    A Social Data: Biases, Methodological Pitfalls, and Ethical Boundaries Alexandra Olteanu Carlos Castillo, Eurecat Fernando Diaz, Microsoft Research Emre Kıcıman, Microsoft Research Social data in digital form, which includes user-generated content, expressed or implicit relationships between people, and behavioral traces, are at the core of many popular applications and platforms, and drive the research agenda of many re- searchers. The promises of social data are many, including understanding “what the world thinks” about a social issue, brand, product, celebrity, or other entity, as well as enabling better decision making in a variety of fields including public policy, healthcare, and economics. Many academics and practitioners have warned against the na¨ıve usage of social data. There are biases and inaccuracies at the source of the data, but also introduced during processing. There are methodological limitations and pitfalls, as well as ethical boundaries and unexpected consequences that are often overlooked. This survey recognizes that the rigor with which these issues are addressed by different researchers varies across a wide range. We present a framework for identifying a broad range of menaces in the research and practices around social data. Additional Key Words and Phrases: Social media, user-generated content, behavioral traces, biases, evaluation 1. INTRODUCTION “For your own sanity, you have to remember that not all problems can be solved. Not all problems can be solved, but all problems can be illuminated.” –Ursula Franklin1 This survey covers a series of concerns on the usage by researchers of social data for a variety of goals. To set the context, in this section, we describe social data and what is it being used for (x1.1), outline general concerns about its usage as voiced by academics in the past (x1.2), and overview the remainder of the survey (x1.3).

  • Chapter 1 Social Big Data: an Overview and Applications
    Chapter 1 Social Big Data: An Overview and Applications Bilal Abu-Salih1, Pornpit Wongthongtham2 Dengya Zhu3 , Kit Yan Chan3 , Amit Rudra3 1The University of Jordan 2 The University of Western Australia 3 Curtin University Abstract : The emergence of online social media services has made a qualitative leap and brought profound changes to various aspects of human, cultural, intellectual, and social life. These significant Big data tributaries have further transformed the businesses processes by establishing convergent and transparent dialogues between businesses and their customers. Therefore, analysing the flow of social data content is necessary in order to enhance business practices, to augment brand awareness, to develop insights on target markets, to detect and identify positive and negative customer sentiments, etc., thereby achieving the hoped-for added value. This chapter presents an overview of Social Big Data term and definition. This chapter also lays the foundation for several applications and analytics that are broadly discussed in this book. Keywords: Social Big Data; Social Credibility; Domain Knowledge; Sentiment Analysis; Affective Design; Predictive Analytics; 1.1 Introduction The social media services, positioned on the throne of cyberspace, in their broad sense, cover an ample set of freely accessible electronic platforms that are built to encourage and simplify communication between people with similar interests by enabling interactive conversations and exchanging information regardless of physical location. Those virtual platforms are continuing to spread exponentially by providing social communication services to their affiliated members. The services offered by these sites have expanded, providing their consumers with extensive possibilities for exchanging information in the fields of education, health, culture, sports and other domains of knowledge [1, 2].

  • Over a Decade of Social Opinion Mining: a Systematic Review
    Over a Decade of Social Opinion Mining: A Systematic Review Keith Cortis ADAPT Centre, Dublin City University, Ireland [email protected] Brian Davis ADAPT Centre, Dublin City University, Ireland [email protected] Abstract Social media popularity and importance is on the increase due to people using it for various types of social interaction across multiple channels. This sys- tematic review focuses on the evolving research area of Social Opinion Mining, tasked with the identification of multiple opinion dimensions, such as subjectiv- ity, sentiment polarity, emotion, affect, sarcasm and irony, from user-generated content represented across multiple social media platforms and in various media formats, like text, image, video and audio. Through Social Opinion Mining, nat- ural language can be understood in terms of the different opinion dimensions, as expressed by humans. This contributes towards the evolution of Artificial In- arXiv:2012.03091v2 [cs.CL] 6 Jul 2021 telligence which in turn helps the advancement of several real-world use cases, such as customer service and decision making. A thorough systematic review was carried out on Social Opinion Mining research which totals 485 published studies and spans a period of twelve years between 2007 and 2018. The in-depth analysis focuses on the social media platforms, techniques, social datasets, lan- guage, modality, tools and technologies, and other aspects derived. Social Opin- ion Mining can be utilised in many application areas, ranging from marketing, Preprint submitted to Artificial Intelligence Review July 8, 2021 advertising and sales for product/service management, and in multiple domains and industries, such as politics, technology, finance, healthcare, sports and gov- ernment.

  • Computational Perspectives on Large-Scale Social Networks
    COMPUTATIONAL PERSPECTIVES ON LARGE-SCALE SOCIAL NETWORKS A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Johan Holke Olof Ugander August 2014 c 2014 Johan Holke Olof Ugander ALL RIGHTS RESERVED COMPUTATIONAL PERSPECTIVES ON LARGE-SCALE SOCIAL NETWORKS Johan Holke Olof Ugander, Ph.D. Cornell University 2014 This thesis investigates both how computational perspectives can improve our under- standing of social networks, and also how modern insights about social networks can be put to work to address difficult computational and inferential challenges across systems engineering and the social sciences. The microstructure of human behavior has a rich history of study across many disciplines, and only recently — through the data deluge of online instrumentation and experimentation — has the role networks play across social and economic domains come into full view. Work in this thesis examines how social net- work neighborhoods, the rich local networks that surround individuals, function as con- tact surfaces through which individuals process information, mediating social decision and social contagion processes. Work in this thesis on distributing graph computations at Facebook, the online social networking service, has led to dramatic efficiency gains there, successfully deploying a new partitioning algorithm to reduce average query times for their “People You May Know” link prediction system by 50%. These improvements were achieved by harnessing both geographic and network structures of social graphs not necessarily found in other graph contexts. Additional work presents a highly scal- able “restreaming” approach to partitioning massive graphs with rich local structure.

  • Exploring the Value of Big Data Analysis of Twitter Tweets and Share Prices
    Exploring the value of Big Data analysis of Twitter tweets and share prices A Thesis submitted by Peter Wlodarczak, B.Sc. Computer Science, MBA For the award of Doctor of Philosophy, 2017 Peter Wlodarczak Abstract Over the past decade, the use of social media (SM) such as Facebook, Twitter, Pinterest and Tumblr has dramatically increased. Using SM, millions of users are creating large amounts of data every day. According to some estimates ninety per cent of the content on the Internet is now user generated. Social Media (SM) can be seen as a distributed content creation and sharing platform based on Web 2.0 technologies. SM sites make it very easy for its users to publish text, pictures, links, messages or videos without the need to be able to program. Users post reviews on products and services they bought, write about their interests and intentions or give their opinions and views on political subjects. SM has also been a key factor in mass movements such as the Arab Spring and the Occupy Wall Street protests and is used for human aid and disaster relief (HADR). There is a growing interest in SM analysis from organisations for detecting new trends, getting user opinions on their products and services or finding out about their online reputation. Companies such as Amazon or eBay use SM data for their recommendation engines and to generate more business. TV stations buy data about opinions on their TV programs from Facebook to find out what the popularity of a certain TV show is. Companies such as Topsy, Gnip, DataSift and Zoomph have built their entire business models around SM analysis.

  • Information Revolution from Data to Policy Action in Low-Income Countries: How Can Innovation Help?
    Information Revolution From Data to Policy Action in Low-Income Countries: How Can Innovation Help? Matjaž Jug PARIS21 Partnership in Statistics for Development in the 21st Century Discussion Paper No. 3 April 2014 Disclaimer The opinions expressed in this paper are those of the author and should not be attributed to the PARIS21 partnership or its members. Abstract While the volume and diversity of data available to researchers, policy analysts and decision- makers is growing, it is clear that traditional methods and approaches aren’t enough to realize the potential of these new data sources. The environment in low-income countries poses some additional challenges to the ways to collect, analyse, disseminate and use data. This paper investigates technological trends and enabling initiatives and opportunities that can significantly improve collection, analysis and dissemination of relevant, accurate and timely information for policy action in low income countries. Examples of innovative approaches in emerging areas like mobile data collection, big data, visualisation, and data dissemination, are presented and investigated in terms of their potential for improved policy action. Introduction The Report of the High-Level Panel of Eminent Persons on the Post-2015 Development Agenda has identified how new goals and measurable targets could be framed in the wake of transformative shifts, calling for a data revolution for sustainable development, with a new international initiative to improve the quality of statistics and information available to citizens. “We should actively take advantage of new technology, crowd sourcing, and improved connectivity to empower people with information on the progress towards the targets.”1 Information needs and challenges in low-income countries Information needs underpin policy action in our global, diverse, and fast changing environment in many different ways.
