The International AAAI Conference on Web and Social Media (ICWSM) is a forum for researchers from multiple disciplines to come together to share knowledge, discuss ideas, exchange information, and learn about cutting-edge research in diverse fields with the common theme of online social media. This overall theme includes research in new perspectives in social theories, as well as computational algorithms for analyzing social media. ICWSM is a singularly fitting venue for research that blends social science and computational approaches to answer important and challenging questions about human social behavior through social media while advancing computational tools for vast and unstructured data.

ICWSM, now in its seventeenth year, has become one of the premier venues for computational social science, and previous years of ICWSM have featured papers, posters, and demos that draw upon network science, machine learning, computational linguistics, sociology, communication, and political science. The uniqueness of the venue and the quality of submissions have contributed to a rapidly growing conference, and a competitive acceptance rate of approximately 20% for full-length research papers published in the proceedings by the Association for the Advancement of Artificial Intelligence (AAAI).

ICWSM-2023 will be held from June 5th – 8th at the St. Raphael Resort and Marina in Limassol, Cyprus.

The Shortcut - Why Intelligent Machines do not Think Like Us
by Nello Cristianini

Abstract: The key to address our social anxieties in the face of Intelligent Machines is understanding how they “think”, what we can expect of them, and what can be the consequences of the specific type of intelligence that they exhibit, and the specific position we have chosen for them in our global data infrastructure, particularly web and social media. In order to do that, we will examine the fundamental steps that took us to the present form of AI, in particular the idea of the Shortcut. This will allow us to consider what we can expect from modern AI, and how we can manage our relation with it. (This talk will be based on the book “The Shortcut” by Nello Cristianini).

Bio: Nello Cristianini is a Professor of Artificial Intelligence at the University of Bath, and a researcher in many areas of Artificial Intelligence, including machine learning theory, natural language processing, social implications of AI, philosophical foundations of AI, computational social science. He is the author of “The Shortcut” published by CRC Press (2023).

Digital Inequality During COVID-19 Lockdowns
by Eszter Hargittai

Abstract: Rarely is access to information as important as during a global health crisis. During the initial COVID-19 lockdowns, at a time when information could mean the difference between life and death, information inequalities were of paramount significance. Drawing on national survey data collected in the early days of the pandemic in three countries (US, Italy, Switzerland), this talk shares how people’s digital privilege related to their knowledge and misconceptions about the virus with consequences for whether they stayed safe during lockdowns.

Bio: Eszter Hargittai is Professor and holds the Chair of Internet Use and Society at the Institute of Communication and Media Research of the University of Zurich. She is Fellow of the International Communication Association and an External Member of the Hungarian Academy of Sciences. Hargittai's research looks at how people may benefit from or be left behind as a result of their varied digital media skills and uses. Her work has received awards from several professional associations. Her latest book is Connected in Isolation: Digital Privilege in Unsettled Times published by The MIT Press in 2022.

Prevalence Estimation in Social Media Using Black Box Classifiers

Abstract: Many problems in computational social science require estimating the proportion of items with a particular property. This counting task is called prevalence estimation or quantification. Frequently, researchers have a pre-trained classifier available to them. However, it is usually not safe to simply apply the classifier to all items and count the predictions of each class, because the test dataset may differ in important ways from the dataset on which the classifier was trained, a phenomenon called distribution shift. In addition, a second type of distribution shift may occur when one wishes to compare the prevalence between multiple datasets, such as tracking changes over time. To cope with that, some assumptions need to be made about the nature of possible distribution shifts across datasets, a process that we call extrapolation.

This tutorial will introduce an end-to-end framework for prevalence estimation using black box (pre-trained) classifiers, with a focus on social media datasets. The framework consists of a calibration phase and an extrapolation phase, aiming to address the two types of distribution shifts described above. We will provide hands-on exercises that walk the participants through solving a real world problem of quantifying positive tweets in datasets from two separate time periods. All datasets, pre-trained models, and example codes will be provided in a Jupyter notebook. After attending this tutorial, participants will be able to understand the basics of the prevalence estimation problem in social media, and construct a data analysis pipeline to conduct prevalence estimation for their projects.

Computational Approaches to Studying Anti-Social Behaviour in Social Media

Abstract: In less than a generation, social media has moved into the center of modern life. It has altered many aspects of our daily lives, from how we form and maintain social relationships to how we discover, access and share information online. However, the same platforms have also given way to troublesome anti-social behaviours such as online trolling, cyberbullying, and expressions of hate speech. In some online communities, what is commonly referred to as ‘anti-social’ may be a communal norm and a way to socialize. However, that is not the case in most online communities where such behaviour may negatively affect the overall group cohesion and may have psychological and emotional consequences for individual social media users.

This tutorial will demonstrate how to use automated content analysis to detect and study anti-social behaviours in social media. The session will introduce and discuss advantages and disadvantages of two common approaches often used to detect instances of ‘anti-social’ behaviour in online discourse: lexicon-based and machine learning approaches. As part of the hands-on part, the tutorial will introduce Communalytic, a new online research tool for studying online communities. The participants will then use Communalytic to analyze a sample dataset using a toxicity analysis.

A hitchhiker’s guide to user-centric browsing data Cancelled

Abstract: Digital traces come in two rather different forms, depending on whether they are venue-centric or user-centric. Venue-centric data consists of everything users did on a given site or platform in a given context (e.g. all ‘stop the steal’ tweets published on Twitter over a certain period). User-centric data consists of everything a certain population of users did in a given context (e.g. monitoring data from wearable devices for a set of people who agreed to share their data for a specific research). Venue-centric data typically is massive, anonymous and full of blind spots, when user-centric data typically is more scarce but richer in external knowledge about people involved (social demographics but also possibly complementary survey data) and more thorough (because they are not limited to what people did on a specific platform). The aim of the present tutorial is to introduce researchers to opportunities and challenges associated with using user-centric data for research on web behavior, showing focusing on a specific kind of such data, namely browsing trace data collected via passive metering devices installed on personal mobile and laptops supplemented with extra survey data. We aim at presenting both methods (starting from data cleaning and preprocessing to data analysis and statistical modeling) and potential research questions (in terms of broad social science interests) that are specially relevant to user-centric browsing data.
