ICWSM Code of Conduct

For inquiries about the code of conduct, please contact

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 sixteenth 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.

ICWSM-2022 Keynotes

The importance of multiple languages and multiple cultures in NLP research

Alice Oh

Abstract: Among the thousands of human languages used throughout the world, NLP researchers have so far focused on only a handful. This is understandable from the perspective that resources and researchers are not readily available for all languages, but nevertheless it is a profound limitation of our research community, one that must be addressed. I will discuss research on Korean and other low- to medium-resource languages and share the interesting findings that extend beyond the linguistic differences. I will share our work on ethnic bias in BERT language models in six different languages which particularly illustrates the importance of studying multiple languages. I will describe our efforts in building a benchmark dataset for Korean and the main challenge of building the dataset when the sources of data are much smaller compared to English and other major languages. I will also present our latest findings with historical documents written in ancient Korean. Finally, I will share some preliminary results of working with non native speakers who can potentially contribute to research in low-resource languages. Through this talk, I hope to inspire NLP researchers, myself included, to actively engage in a diverse set of languages and cultures.

Bio: Alice Oh is a Professor in the School of Computing at KAIST. She received her PhD in 2008 from MIT and joined KAIST in the same year. Her major research area is at the intersection of machine learning and computational social science. Within machine learning, she studies various models designed for analyzing written text including social media posts, news articles, and personal conversations. She also looks at non-textual data such as social network friendship and logs from online games for which she interacts closely with social scientists for an interdisciplinary approach to computational social science. A particular application focus of applying computational methods to a social science problem is computer science education. Her students have developed a Web-based system for improving programming education, and through that system they collect and analyze large-scale, fine-grained student behavior data. With that data, they aim to understand the behaviors of students and teaching assistants via machine learning models such that they can offer identification of students in need of assistance, provide automatic assistance for simple problems, track students’ progress, and help students to learn better through social learning.

Perceived Gender and Political Persuasion: A Social Media Field Experiment during the 2020 Democratic National Primary

Chris Bail

Abstract: Women have less influence than men in many decision-making settings. We evaluate possible sources of this gender gap using a field experiment conducted during the 2020 presidential primary. We paid Democrats to discuss their preferred candidates with another voter on a social media platform that we created called UniteDem. Within these conversations, we randomly assigned some respondents to appear to their partners using gendered avatars that did not match their gender identity. We find that misrepresenting a man as a woman undermines his influence on his partner’s candidate preferences. However, misrepresenting a woman as a man does not significantly increase her relative influence. Additionally, we find evidence of gender differences in word use. The results indicate that both gender stereotypes and differences in speech contribute to a gender gap in interpersonal influence, suggesting that changes to a woman’s behavior or a man’s perception alone will not improve inequalities in women’s influence.

Deep Learning For Human Mobility: Data, Models, and Challenges

Abstract: Urban population is increasing strikingly and human mobility is becoming more complex and bulky, affecting societal aspects such as the spreading of viral diseases (e.g., the COVID-19 pandemics), public and private transportation, well-being, and the quality of the environment. The proliferation of digital mobility data, such as phone records, GPS traces, and social media posts, combined with the outstanding predictive power of AI, triggered the application of deep learning to human mobility. Currently, the literature is mainly focusing on three mobility-related tasks: next-location prediction, which is predicting an individual's future locations; crowd flow prediction, which is forecasting flows on a geographic region; and trajectory generation, i.e., generating realistic individual trajectories. In this tutorial, we provide the audience with: (i) an introduction to the fundamental concepts of human mobility, such as trajectories, flows, tessellations, and mobility patterns; (ii) a review of mobility data sources and common public datasets; (iii) a definition of next-location, crowd flow prediction, and trajectory generation, and a discussion of why they are relevant and challenging problems; (iv) a description of peculiarities and limitations of the deep learning approaches to these three problems, with practical examples on how to train and use them; (v) a discussion about relevant open technical challenges and promising research directions. On the one hand, our tutorial is a guide to the leading deep learning solutions for people already working on human mobility. At the same time, it helps AI scientists and practitioners understand the fundamental concepts and the open challenges of the study of human mobility. Our tutorial is based on our recent review paper, available at

BERT for Social Sciences and Humanities

Abstract: In this interactive tutorial, we will introduce participants to large language models that are now common in natural language processing (NLP). We will focus on variants of the popular Bidirectional Encoder Representations from Transformers (BERT) model (Devlin et al., 2018). This family of pre-trained models performs well across a wide range of NLP tasks, but their use poses challenges for researchers in other disciplines. This tutorial will highlight opportunities for social media researchers, from the humanities and social sciences, to take advantage of these large models. Participants will gain hands-on experience with downloading and setting up a pre-trained model, using BERT to analyze words in context, adapting or “fine-tuning” a BERT model to perform better on a curated dataset, and using the fine-tuned model for classification tasks. We will also discuss practical details, like how to run these large models using free resources and which open libraries to use. Most importantly, we will discuss nuances of these models that are most relevant for researchers outside of NLP, including example use cases and exploratory uses of these models; limits to these methods and common errors; using datasets of varying sizes, including small, curated collections; and data processing and tokenization choices.

Trustworthy Business Decision Making Methodologies in Web and Social Media

Abstract: Online controlled experiments are the gold standard for tech companies decision making and feature iterations. However, in a social media setting, experimenters often face unique challenges including inconsistency between short-term and long-term results, correlated impacts between content producer and consumers, and/or external validation of online experiment results. These issues make it difficult to interpret and understand experiment results, and create hurdles to leverage them to make informed decisions. There are multiple data science tools and causal inference frameworks which can be applied to improve scientific rigor for the decision making process. In this tutorial, we will first review the causal inference methodologies. Then we will introduce double machine learning, surrogate modeling and meta analysis framework with some Twitter’s applications. Finally there will be a hands-on interactive session for the audience to learn how to apply those techniques in their research.

Misinformation and Disinformation in Social Media: Where we are and the Path Ahead

Abstract: This tutorial will address the problem of false information and its propagation in media. In order to take a holistic view, on the one end, we need to look at the very related problem of misinformation and disinformation in newspapers in the early 20th century and how society evolved to eradicate the most egregious of its forms and learned to live with it. On the other end, we will survey the promising technological solutions that have been designed in the last 5-10 years and a bit. The issue of digital literacy will be examined and efforts to teach our school-children how to determine the trustworthiness of information will be discussed. Solutions involving trustworthy third-parties and digital signatories will be evaluated. Time permitting, we will demonstrate these issues studying a few cases and demonstrations. We will also look at governmental policies that have been designed to curb this problem. Finally, an agenda for future work will be discussed.

Controlling for Text in Causal Inference with Double Machine Learning

Abstract: Text plays an increasingly important role in the study of causal relationships. In this tutorial, we consider the specific case of using text as a control to eliminate bias from confounders operating through the text. We formalize the problem of controlling for text using causal graphs and the potential outcomes framework, describe principled estimation and inference procedures to realize this goal using dou-ble/debiased machine learning, and compare this procedure (hands-on) against several alternatives such as controlling for low-dimensional representations of the text obtained via topic modeling, principal component analysis, or other techniques. We conclude with a case study on using text as a control to quantify the causal impact of status on persuasion online.

Organizer:Emaad Manzoor is an assistant professor at the University of Wisconsin Madison. He designs randomized and quasi-experiments to quantify the determinants of persuasion in text-based communication. He received his PhD from Carnegie Mellon University.

Using Word Embeddings to Measure Group and Temporal Differences in Meaning

Abstract: Word embeddings — representation of words as vectors such that words with similar meanings share geometrical properties — have become standard instruments in a text analyst's toolkit. Two types of representations have gained popularity: a single vector per word invariant to context (non-contextual embeddings) or multiple vectors per word that are sensitive to linguistic context (contextual embeddings). This tutorial is aimed to provide a hands-on introduction to both non-contextual and contextual word embeddings. We’ll demonstrate the utility of these embeddings on measuring differences in meaning across groups (e.g., political parties, subreddits, etc) or over time. The tutorial is designed for an audience who wants to get started with using word embeddings in their own research. Through the tutorial, we will give a conceptual overview of these two types of embeddings, highlight the differences between them, and include a deeper examination through code about how they can be used to analyze variation or change in meaning.

Organizer: Sandeep Soni is a Postdoctoral scholar at the University of California, Berkeley. His research interest is broadly in the field of computational linguistics with an emphasis in studying the social aspects of language. He finished his PhD at Georgia Institute of Technology.

ICWSM Student Volunteer Program

We seek a limited number of student volunteers for ICWSM 2022, for both on-site and virtual versions. Student volunteers must be full-time undergraduate or graduate students at colleges and universities; have an accepted paper in the conference program or are participating in another way (workshops, demos, engagement with the organizing committee). Student volunteers will be asked to assist ICWSM organizers before and during the conference for a few hours. This may involve helping to arrange or host activities, and support in the planning and execution of conference-related tasks. In exchange, student volunteers will receive free conference registration (both main programs and workshops/tutorials). In the event that applications exceed the number of available places, we will aim to keep the volunteer team diverse in terms of language, geo-location, gender, etc.

To apply for the ICWSM 2022 Student Volunteer Program, please complete the online application at the link below no later than April 20, 2022. Notifications will be sent by April 27, and complimentary registrations will be issued through AAAI.

ICWSM Awards

ICWSM Adamic-Glance Distinguished Young Researcher Award

This annual award is presented to a young researcher who has distinguished themself through innovative research in the area of social computing/computational social science in the early stage of their independent research career. The award is named after Lada Adamic and Natalie Glance, two outstanding researchers who have made significant contributions to the International AAAI Conference on Web and Social Media (ICWSM) in particular and social computing/computational social science in general. The ICWSM research community at large has greatly impacted this field, through identifying the connections between online digital behaviors and critical societal questions and issues. From misinformation and fake news to how we can use social media and social networks to gain insight into political polarization, mental health, and social movements, the range of topics addressed by the community is continuously expanding. We want to recognize and celebrate the young researchers who are making these contributions today.

The award was established in 2021, at the 15th anniversary mark of the AAAI ICWSM conference.

The inaugural awardee is Dr. Tanu Mitra.

Nomination Process and Eligibility

Self-nominations, nominations, and letters of support are elicited.. ICWSM strongly encourages individuals from underrepresented groups in research (based on gender identity, race, ethnicity, geographical location, etc.) to self-nominate, and urges the wide community to nominate young researchers who have distinguished themselves for their creativity and rigor in identifying and addressing important research topics of societal impact. Nominations are open from February 1st to March 1st 2022.

Eligibility Criteria

The award is open to individuals who:

  1. Have received their PhD within the past 7 years. Career interruptions and other special circumstances will be considered and should be mentioned in the nomination justification document.
  2. Perform research that is recognizably within the broad field of social computing/computational social science in terms of their thematic and methodological approaches.
  3. Have published their research in the top venues for social computing or computational social science, including active participation in ICWSM.

As long as a candidate is eligible based on the three criteria above, they will be considered even if they were nominated or self-nominated in prior years.

Selection Process

The selection committee consists of three to five members and is appointed by the AAAI ICWSM Steering Committee Chair. The committee solicits self-nominations, nominations, and letters of support from the social computing/computational social science community. The selection is based on the impact of the candidate's work in the field in identifying significant new problems, creating promising new ideas, paradigms, and tools related to data-driven understanding of human behavior, which may be quantitative or qualitative in nature. Depth and impact are valued over breadth of contribution for this award. A strong regard for considering the ethical aspects of the data/methods used in social computing/computational social science is expected of the research record those nominated.

The nomination form asks the following questions:

  1. Nominator’s information (name, affiliation, email, a link to their webpage).
  2. Nominee’s information (name, affiliation, email, year of PhD, a link to their webpage that contains additional information, for example their CV/resume).
  3. A one-page statement explaining why the nominee deserves the award in question, especially highlighting the novelty and strength of their contributions in the area of computational social science / social computing, and providing evidence of their academic and societal impact. A second page can be included to contain information about career interruption or any special considerations.
  4. Citations for up to three representative publications and/or links to other artefacts documenting the contribution or impact.

Note for letters of support: The form makes it easy to submit letters of support from people other than the nominators or self-nominators. Such individuals will not need to complete the details of the nomination, they will simply upload their letter.

Form accessibility: The nomination form requires Google authentication. If for any reason this is a problem for the nominator, please send the nomination materials via email to:

Conflict of interest: The awards committee takes conflict of interest seriously. If an nominated individual is a former or current collaborator of one or more of the committee members, such member(s) recuse themselves from evaluating and voting on these nominations.
