Abstract

Three of the world's most accomplished and deep thinkers come together to explore Artificial Intelligence (AI) and the way it is transforming human society-and what this technology means for us all. An AI learned to win chess by making moves human grand masters had never conceived. Another AI discovered a new antibiotic by analyzing molecular properties human scientists did not understand. Now, AI-powered jets are defeating experienced human pilots in simulated dogfights. AI is coming online in searching, streaming, medicine, education, and many other fields and, in so doing, transforming how humans are experiencing reality. In The Age of AI, three leading thinkers have come together to consider how AI will change our relationships with knowledge, politics, and the societies in which we live. The Age of AI is an essential roadmap to our present and our future, an era unlike any that has come before. Artificial Intelligence (AI) is transforming human society in fundamental and profound ways. Not since the Age of Reason have we changed how we approach security, economics, order, and even knowledge itself. In the Age of AI, three deep and accomplished thinkers come together to consider what AI will mean for us all.

Abstract

Purpose Public attitudes towards COVID-19 and social distancing are critical in reducing its spread. It is therefore important to understand public reactions and information dissemination in all major forms, including on social media. This article investigates important issues reflected on Twitter in the early stages of the public reaction to COVID-19. Design/methodology/approach A thematic analysis of the most retweeted English-language tweets mentioning COVID-19 during March 10-29, 2020. Findings The main themes identified for the 87 qualifying tweets accounting for 14 million retweets were: lockdown life; attitude towards social restrictions; politics; safety messages; people with COVID-19; support for key workers; work; and COVID-19 facts/news. Research limitations/implications Twitter played many positive roles, mainly through unofficial tweets. Users shared social distancing information, helped build support for social distancing, criticised government responses, expressed support for key workers and helped each other cope with social isolation. A few popular tweets not supporting social distancing show that government messages sometimes failed. Practical implications Public health campaigns in future may consider encouraging grass roots social web activity to support campaign goals. At a methodological level, analysing retweet counts emphasised politics and ignored practical implementation issues. Originality/value This is the first qualitative analysis of general COVID-19-related retweeting.

Abstract

Accurate demand forecasting plays a critical role in hotel revenue management. Online reviews have emerged as a viable information source for hotel demand forecasting. However, existing hotel demand forecasting studies leverage only sentiment information from online reviews, leading to capturing insufficient information. Furthermore, prevailing hotel demand forecasting methods either lack explainability or fail to capture local correlations within sequences. In this study, we (1) propose a comprehensive framework consisting of four components: expertise, sentiment, popularity, and novelty (ESPN framework), to investigate the impact of online reviews on hotel demand forecasting; (2) propose a novel dual attention-based long short-term memory convolutional neural network (DA-LSTM-CNN) model to optimize the model effectiveness. We collected online review data from Ctrip.com to evaluate our proposed ESPN framework and DA-LSTM-CNN model. The empirical results show that incorporating features derived from the ESPN improves forecasting accuracy and our DA-LSTM-CNN significantly outperforms the state-of-the-art models. Further, we use a case study to illustrate the explainability of the DA-LSTM-CNN, which could guide future setups for hotel demand forecasting systems. We discuss how stakeholders can benefit from our proposed ESPN framework and DA-LSTM-CNN model.

Abstract

Politics is about the distribution of goods and risks. We can describe the distribution of goods, and we can also characterize those distributions as a kind of inequality. As a baseline definition of "politics of information" we mean the distribution of information goods across different populations. Despite a strong tradition of disciplinary focus in information science, much of the literature is still given over to fairly simple notions of social form and structure. A nascent knowledge organization practice dedicated to social difference is explicitly motivated by justice and nomenclature. Not only is knowledge organization a tool of cultural hegemony, but also it can be read as a product of cultural ordering and bias. Identifying unjust and politically oppressive practice must be part of the path to justice. Understanding the political construction of knowledge organization is essential for the theory of information service in order to build a more just professional practice.

Abstract

As the prevalence of online misinformation grows increasingly apparent, our need to understand its spread becomes more essential. Trolling, in particular, may aggravate the spread of misinformation online. While many studies have investigated the negative impact of trolling and misinformation on social media, less attention has been devoted to the relationships between the two and their manifestation on social question and answer (SQA) sites. We examine the extent of and relationships between trolling and misinformation on SQA sites. Through content analysis of 8,401 posts (159 questions and 8,242 answers) from the Yahoo Answers! Politics & Government and Society & Culture categories, we identified levels of and relationships between misinformation and trolling. We find that trolling and misinformation tend to reinforce themselves and each other and that trolling and misinformation are more common in the Politics & Government category than in the Society & Culture category. Our study is among the first to consider the prevalence of and relationship between misinformation and trolling on SQA sites.

Abstract

Constructivism in the social sciences has known several ups and downs over the last decades. It was successful rather early in sociology but hotly contested in International Politics/Relations (IR). Oddly enough, just at the moments it made important inroads into the research agenda and became accepted by the mainstream, the enthusiasm for it waned. Many constructivists-as did mainstream scholars-moved from "grand theory" or even "meta-theory" toward "normal science," or experimented with other (eclectic) approaches, of which the turns to practices, to emotions, to new materialism, to the visual, and to the queer are some of the latest manifestations. In a way, constructivism was "successful," on the one hand, by introducing norms, norm-dynamics, and diffusion; the role of new actors in world politics; and the changing role of institutions into the debates, while losing, on the other hand, much of its critical potential. The latter survived only on the fringes-and in Europe more than in the United States. In IR, curiously, constructivism, which was rooted in various European traditions (philosophy, history, linguistics, social analysis), was originally introduced in Europe via the disciplinary discussions taking place in the United States. Yet, especially in its critical version, it has found a more conducive environment in Europe than in the United States.
In the United States, soon after its emergence, constructivism became "mainstreamed" by having its analysis of norms reduced to "variable research." In such research, positive examples of for instance the spread of norms were included, but strangely empirical evidence of counterexamples of norm "deaths" (preventive strikes, unlawful combatants, drone strikes, extrajudicial killings) were not. The elective affinity of constructivism and humanitarianism seemed to have transformed the former into the Enlightenment project of "progress." Even Kant was finally pressed into the service of "liberalism" in the U.S. discussion, and his notion of the "practical interest of reason" morphed into the political project of an "end of history." This "slant" has prevented a serious conceptual engagement with the "history" of law and (inter-)national politics and the epistemological problems that are raised thereby. This bowdlerization of constructivism is further buttressed by the fact that in the "knowledge industry" none of the "leading" U.S. departments has a constructivist on board, ensuring thereby the narrowness of conceptual and methodological choices to which the future "professionals" are exposed. This article contextualizes constructivism and its emergence within a changing world and within the evolution of the discipline. The aim is not to provide a definition or a typology of constructivism, since such efforts go against the critical dimension of constructivism. An application of this critique on constructivism itself leads to a reflection on truth, knowledge, and the need for (re-)orientation.

Abstract

Although the Internet allows people to circulate messages using different media, most censorship studies discuss the removal of text content. This article presents a systematic study regarding the censorship of both plain text and multimedia content on the Chinese Internet. By analyzing both censored and surviving posts on the Chinese social media platform Weibo during the 2014 Hong Kong Umbrella Movement, we find that multimedia posts suffered more intensive censorship deletion than plain text posts, with censorship programs being oriented more toward multimedia content like images than the text content of multimedia posts. Our analysis has significant implications for censorship studies, information control, and politics in the "post-text" era.

Abstract

Critical race theory (CRT) is a framework that evolved from critical legal studies of the 1970s but has only recently been the target of intense scrutiny in education and politics. This article aims to describe CRT and how it can frame issues within cataloging and classification standards and practice. CRT tenets permanence of racism, whiteness as property, the critique of liberalism, intersectionality, counter-storytelling, and interest convergence are explored in the context of cataloging and classification work. Concepts of "authority" and "justice" are also examined. CRT can provide valuable evidence for critical cataloging efforts to make cataloging more diverse, equitable, and inclusive.

Abstract

COVID-19 is an unprecedented global health crisis that will have immeasurable consequences for our economic and social well-being. Tedros Adhanom Ghebreyesus, the director general of the World Health Organization, stated "We're not just fighting an epidemic; we're fighting an infodemic". Currently, there is no robust scientific basis to the existing definitions of false information used in the fight against the COVID-19infodemic. The purpose of this paper is to demonstrate how the use of a novel taxonomy and related model (based upon a conceptual framework that synthesizes insights from information science, philosophy, media studies and politics) can produce new scientific definitions of mis-, dis- and malinformation. We undertake our analysis from the viewpoint of information systems research. The conceptual approach to defining mis-,dis- and malinformation can be applied to a wide range of empirical examples and, if applied properly, may prove useful in fighting the COVID-19 infodemic. In sum, our research suggests that: (i) analyzing all types of information is important in the battle against the COVID-19 infodemic; (ii) a scientific approach is required so that different methods are not used by different studies; (iii) "misinformation", as an umbrella term, can be confusing and should be dropped from use; (iv) clear, scientific definitions of information types will be needed going forward; (v) malinformation is an overlooked phenomenon involving reconfigurations of the truth.

Abstract

Algorithms influence every facet of modern life: criminal justice, education, housing, entertainment, elections, social media, news feeds, work... the list goes on. Delegating important decisions to machines, however, gives rise to deep moral concerns about responsibility, transparency, freedom, fairness, and democracy. Algorithms and Autonomy connects these concerns to the core human value of autonomy in the contexts of algorithmic teacher evaluation, risk assessment in criminal sentencing, predictive policing, background checks, news feeds, ride-sharing platforms, social media, and election interference. Using these case studies, the authors provide a better understanding of machine fairness and algorithmic transparency. They explain why interventions in algorithmic systems are necessary to ensure that algorithms are not used to control citizens' participation in politics and undercut democracy.

Abstract

A second presidential social media transition in the United States occurred as Joe Biden took office on January 20, 2021. In the years since Barack Obama pioneered the use of platforms like Facebook and Twitter while President, Donald Trump shaped his Presidency around the use of Twitter, primarily through a personal account created before entering politics. In this paper, we examine Donald Trump's use of Twitter during his presidency as a lens through which to understand the ongoing archival preservation and data management challenges posed by social media platforms. The blurred lines between public and private records, deleting tweets, and the preservation issues that appeared after his suspension from Twitter and other platforms following the January 6, 2021 insurrection at the US Capitol all highlight an urgent, ongoing need by archivists, digital preservationists, and information scholars to consider how we might collect and manage social media records in an ever-changing information landscape. This paper draws primarily on publicly available information from existing preservation initiatives to analyze the state of digital preservation for presidential records. Our findings highlight how both public and private entities manage and provide access to Donald Trump's tweets, pointing to broader implications for social media data preservation.

Abstract

Records are persistent representations of activities created by partakers, observers, or their authorized proxies. People are generally willing to trust vital records such as birth, death, and marriage certificates. However, conspiracy theories and other misinformation may negatively impact perceptions of such documents, particularly when they are associated with a significant person or event. This paper explores the relationship between archival records and trustworthiness by reporting results of a survey that asked genealogists about their perceptions of 44th U.S. President Barack Obama's birth certificate, which was then at the center of the "birtherism" conspiracy. We found that although most participants perceived the birth certificate as trustworthy, others engaged in a biased review, considering it not trustworthy because of the news and politics surrounding it. These findings suggest that a conspiracy theory can act as a moderating variable that undermines the efficacy of normal or recommended practices and procedures for evaluating online information such as birth certificates. We provide recommendations and propose strategies for archivists to disseminate correct information to counteract the spread of misinformation about the authenticity of vital records, and we discuss future directions for research.

Abstract

Purpose Belkin and Robertson (1976a) reflected on the ethical implications of theoretical research in information science and warned that there was potential for abuse of knowledge gained by undertaking such research and applying it to information systems. In particular, they identified the domains of advertising and political propaganda that posed particular problems. The purpose of this literature review is to revisit these ideas in the light of recent events in global information systems that demonstrate that their fears were justified. Design/methodology/approach The authors revisit the theory in information science that Belkin and Robertson used to build their argument, together with the discussion on ethics that resulted from this work in the late 1970s and early 1980s. The authors then review recent literature in the field of information systems, specifically information retrieval, social media and recommendation systems that highlight the problems identified by Belkin and Robertson. Findings Information science theories have been used in conjunction with empirical evidence gathered from user interactions that have been detrimental to both individuals and society. It is argued in the paper that the information science and systems communities should find ways to return control to the user wherever possible, and the ways to achieve this are considered. Research limitations/implications The ethical issues identified require a multidisciplinary approach with research in information science, computer science, information systems, business, sociology, psychology, journalism, government and politics, etc. required. This is too large a scope to deal with in a literature review, and we focus only on the design and implementation of information systems (Zimmer, 2008a) through an information science and information systems perspective. Practical implications The authors argue that information systems such as search technologies, social media applications and recommendation systems should be designed with the recipient of the information in mind (Paisley and Parker, 1965), not the sender of that information. Social implications Information systems designed ethically and with users in mind will go some way to addressing the ill effects typified by the problems for individuals and society evident in global information systems. Originality/value The authors synthesize the evidence from the literature to provide potential technological solutions to the ethical issues identified, with a set of recommendations to information systems designers and implementers.
