False News On Social Media: A Data-Driven Survey

In the past few years, the research community has dedicated growing interest to the issue of false news circulating on social networks. The widespread attention on detecting and characterizing false news has been motivated by considerable backlashes of this threat against the real world. As a matter of fact, social media platforms exhibit peculiar characteristics, with respect to traditional news outlets, which have been particularly favorable to the proliferation of deceptive information. They also present unique challenges for all kind of potential interventions on the subject. As this issue becomes of global concern, it is also gaining more attention in academia. The aim of this survey is to offer a comprehensive study on the recent advances in terms of detection, characterization and mitigation of false news that propagate on social media, as well as the challenges and the open questions that await future research on the field. We use a data-driven approach, focusing on a classification of the features that are used in each study to characterize false information and on the datasets used for instructing classification methods. At the end of the survey, we highlight emerging approaches that look most promising for addressing false news

Are All Successful Communities Alike? Characterizing and Predicting the Success of Online Communities

The proliferation of online communities has created exciting opportunities to study the mechanisms that explain group success. While a growing body of research investigates community success through a single measure -- typically, the number of members -- we argue that there are multiple ways of measuring success. Here, we present a systematic study to understand the relations between these success definitions and test how well they can be predicted based on community properties and behaviors from the earliest period of a community's lifetime. We identify four success measures that are desirable for most communities: (i) growth in the number of members; (ii) retention of members; (iii) long term survival of the community; and (iv) volume of activities within the community. Surprisingly, we find that our measures do not exhibit very high correlations, suggesting that they capture different types of success. Additionally, we find that different success measures are predicted by different attributes of online communities, suggesting that success can be achieved through different behaviors. Our work sheds light on the basic understanding of what success represents in online communities and what predicts it. Our results suggest that success is multi-faceted and cannot be measured nor predicted by a single measurement. This insight has practical implications for the creation of new online communities and the design of platforms that facilitate such communities.Comment: To appear at The Web Conference 201

Analysis of Portugal´s Wine Certifying Entities Social Networks as Communication Channels

Almeida, C. M., Afonso, C. M., Serra, M., & António, N. (2023). Analysis of Portugal´s Wine Certifying Entities Social Networks as Communication Channels. In C. M. Q. Ramos, C. M. R. Sousa, N. M. S. Matos, & R. I. Ashqar (Eds.), Measuring Consumer Behavior in Hospitality for Enhanced Decision Making (pp. 121-160). IGI Global. https://doi.org/10.4018/978-1-6684-6607-0.ch007Organizations have used social media networks to build and grow virtual communities, enabling organizations to spread the word about products and services. This research analyzes the activity and effectiveness of the Facebook and Instagram pages of the Portuguese wine certifying entities between January and March 2022, using the updated PRGS (Presence, Response, Generation, Suggestion) model, updated with Engagement, Interaction, and Efficiency. Results show that Facebook stands out as the main social network for wine-certifying entities, with wider communities and more posts. However, when it comes to reactions, Instagram shows superior numbers for most wine-certifying entities’ pages. Instagram indicators show consistent and interesting results, indicating that it is a solid channel for Portuguese wine-certifying entities. These findings shed light on how to improve their online presence and have a more balanced presence on both social media platforms.authorsversionpublishe

ORGANIZING FOR THE DIGITAL WORLD: A PATHWAY TOWARDS THE AGILE MARKETING CAPABILITY

The ultimate goal of this dissertation is to explain how agility intersects in the field of marketing capabilities, in order to deepen the understanding about a new marketing capability: the Agile Marketing Capability. My dissertation consists of three papers. The first paper inquires how the Agile Marketing Capability can be formally theorized and conceptualized, identifying its key theorizing elements and putting the basis for its further exploration and analysis. The outcomes of this first study identify the core dimensions (or constructs) of the Agile Marketing Capability, advance a holistic theoretical model, and discuss the underlying constructs and relationships. With this first conceptualization of a marketing-focused capability of agility, I start outlining a new path of marketing capabilities, seeking to redefine marketing capabilities by learning more about Agile Marketing implementation. Thus, I lay the terrain for future exploration and forecast of this topic, and enrich the debate on the opportunity to integrate agile principles into marketing studies, and ultimately impact marketing capabilities. The second paper provides an initial empirical investigation of agile capability in marketing field, exploring its main defining features and thus elaborating some key theoretical and empirical dimensions which may characterize and compose the Agile Marketing Capability. The outcomes of this second study identify and organize the key theoretical concepts and dimensions of the Agile Marketing Capability in a theoretical framework. To summarize study results I also formulate some propositions, which could stimulate future theoretical and empirical research towards this topic. The findings of this research considerably advance extant knowledge on capabilities greater aligned with digital transformation challenges, which is a topic still at an early stage in current literature. Specifically, the analysis carried out in the second paper improves the understanding on agility in digital and international marketing settings, contributing to extend dynamic capabilities and marketing capabilities literature. In the meantime, the framework and propositions of this study, as well as the empirical findings, contribute to explain what strategic actions are needed to foster marketing agility, thus pursuing and implementing an Agile Marketing Capability. The third and final paper extends the body of knowledge of agile capabilities in marketing field by looking at how different organizations pursue and implement the Agile Marketing Capability. The outcomes of this third study deepen the conceptualization and definition of the Agile Marketing Capability dimensions, proposing a four-stage Agile Marketing Capability maturity framework. The framework provides key actions, activities and behaviours organized in progressive maturity levels to enable organizations to assess and improve their capabilities in Agile Marketing implementation. The findings of this work contribute to deepen the body of knowledge on marketing capabilities and agility research streams, explaining the benefits that could derive from employing agile approaches and capabilities in marketing, and how their employment actually may enhance organizations’ extant marketing capabilities, particularly in turbulent and fast-changing contexts. Notably, the analysis performed in this third study sheds light on progressive behaviors and actions representative of different maturity levels in the development and management of the Agile Marketing Capability. The maturity framework proposed in this paper and the empirical findings clarify to managers and practitioners how to assess current maturity level in the development of such capability, understand potential improvement actions, and, thus, achieve higher levels of performance. Briefly, it provides useful guidelines for organizations to become more agile in their marketing capabilities

Computational Sociolinguistics: A Survey

Language is a social phenomenon and variation is inherent to its social nature. Recently, there has been a surge of interest within the computational linguistics (CL) community in the social dimension of language. In this article we present a survey of the emerging field of "Computational Sociolinguistics" that reflects this increased interest. We aim to provide a comprehensive overview of CL research on sociolinguistic themes, featuring topics such as the relation between language and social identity, language use in social interaction and multilingual communication. Moreover, we demonstrate the potential for synergy between the research communities involved, by showing how the large-scale data-driven methods that are widely used in CL can complement existing sociolinguistic studies, and how sociolinguistics can inform and challenge the methods and assumptions employed in CL studies. We hope to convey the possible benefits of a closer collaboration between the two communities and conclude with a discussion of open challenges.Comment: To appear in Computational Linguistics.

RSS Feeds, Browsing and End-User Engagement

Despite the vast amount of research that has been devoted separately to the topics of browsing and Really Simple Syndication (RSS) aggregation architecture, little is known about how end-users engage with RSS feeds and how they browse while using a feed aggregate. This study explores the browsing behaviors end-users exhibit when using RSS and Atom feeds. The researcher analyzed end-users’ browsing experiences and discusses browsing variations. The researcher observed, tested, and interviewed eighteen (N=18) undergraduate students at the University of Tennessee to determine how end-users engage with RSS feeds. This study evaluates browsing using two variations of tasks, (1) an implicit task with no final goal and (2) an explicit task with a final goal. The researcher observed the participants complete the two tasks and conducted exit interviews, which addressed the end-users’ experiences with Google Reader and provided further explanation of browsing behaviors. The researcher analyzed the browsing behaviors based upon Bates’ (2007) definitions and characteristics of browsing. The results of this exploratory research provide insights into end-user interaction with RSS feeds
