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 fifteenth 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).


Building on the successes in previous years, in addition to the usual program of contributed talks, posters, and demos, ICWSM-2021 will also hold a dedicated day of workshops and tutorials on June 7th, 2021.

Social Science and Sociophysics Track
We will be continuing the 'social science and sociophysics' track at ICWSM-2021 following its successful debut in 2013. This option is for researchers in social science and sociophysics who wish to submit works without publication in the conference proceedings. While papers in this track will not be published, we expect these submissions to describe the same high-quality and complete work as the main track submissions. Papers accepted to this track will be presented either as full-length or poster presentations integrated with the conference, and their abstracts will be published in the conference proceedings. Papers submitted to this track will be reviewed through the same reviewing process as full papers.

Workshops


The ICWSM-2021 Committee invites proposals for Workshops Day at the 15th International AAAI Conference on Weblogs and Social Media (ICWSM-2021). The Workshops Day will be held on June 7th, 2021. Workshop participants will have the opportunity to meet and discuss issues with a selected focus -- providing an informal setting for active exchange among researchers and developers from a wide range of disciplines, including social science and computer science. Workshops are an excellent forum for exploring emerging approaches and task areas, bridging gaps between the social sciences and computing, and elucidating results of exploratory research.


Members of all segments of the social media research community are encouraged to submit proposals. To foster interaction and exchange of ideas, the workshops will be kept small, with up to 40 participants.


The format of workshops will be determined by their organizers. The two main criteria for the selection of the workshops will be the following:

  • The organizers encourage workshops that promote different types of activities, including challenges, games, and brainstorming, and networking sessions. The organizers discourage workshops that are structured as mini-conferences dominated by long talks and short discussions. Workshops should leave ample time for discussions and interaction between the participants and should also encourage the submission and presentation of position papers that discuss new research ideas.
  • The workshop should have the potential to attract the interest of researchers in computer science and social science. Proposals involving people of different backgrounds in the organizing committee and addressing topics at the intersection of different disciplines will have a higher chance of acceptance.

Workshop organizers who want to publish the papers from their workshop (or significant portions of it) will have the opportunity to do so through workshop proceedings by the AAAI Press. For a list of last year's workshops see https://www.icwsm.org/2020/index.html#workshops_schedule.


Workshop proposal content

Proposals for workshops should be no more than five (5) pages in length (10pt, single column, with reasonable margins), written in English, and should contain the following:

  • A concise title
  • The names, affiliations, and contact information of the organizing committee. A main contact author should be specified. A typical proposal should include no more than four co-chairs.
  • An indication as to whether the workshop should be considered for a half-day or full-day meeting.
  • A short abstract describing the scope and main objective of the workshop. Identify the specific issues and research questions the workshop will focus on, with a brief discussion of why the topic is of particular interest at this time and for which research communities.
  • A two/three paragraph description of the workshop topic and themes.
  • A description of the proposed workshop format and a detailed list of proposed activities, with special emphasis on those activities that distinguish it from a mini-conference (e.g., games, brainstorming sessions, challenges, group activities).
  • An approximate timeline of the activities.
  • A description of how workshop submissions will be evaluated and selected (invited contributions, peer review, etc.). In case a PC is needed, provide a tentative list of the members.
  • Historical information about the workshop, if available. Short description of the previous editions reporting highlights and details about the approximate number of attendees and number of submissions.
  • A list of other related workshops held previously at related conferences, if any (list does not have to be exhaustive), together with a brief statement on how the proposed workshop differs from or how it follows-up on work presented at previous workshops.
  • A short bio for each member of the organizing committee, including a description of their relevant expertise. Strong proposals include organizers who bring differing perspectives to the workshop topic and who are actively connected to the communities of potential participants.


Please email your proposal in a single file to the workshop chairs at workshops@icwsm.org before the deadline. For additional information please contact the workshop chairs at the same address.

Tutorials


ICWSM-2021 invites proposals for Tutorials Day at the 15th International AAAI Conference on Web and Social Media (ICWSM). ICWSM-2021 is seeking proposals for tutorials on topics related to the analysis and understanding of social phenomena in the following themes:


  • Course: Traditional tutorials to teach concepts, methodologies, tools, and software packages. We encourage hands-on tutorials that promote interactivity.
  • Translation: Tutorials that aim to translate concepts between disciplines. For example, such a tutorial could introduce social science concepts to computer scientists, or computational concepts to social scientists. Thus, these tutorials should be geared towards a beginner audience.
  • Case study: Focused tutorials that emphasize real world applications of ICWSM work. These tutorials should walk the audience through how research insights and tools were applied in practice. We welcome submissions from practitioners in industry, government, and NGOs in addition to academics.

We welcome tutorials of various lengths (including 45 minutes, 90 minutes, or a half day). We are looking for contributions from experts in both the social and computational sciences, in industry, academia, and beyond. For a list of tutorials from previous years, we encourage you to visit the tutorials page for 2018, 2019 and 2020.


Acceptance criteria

The format will be entirely determined by the tutorial organizers—i.e., you! Proposals will be selected for inclusion considering the following criteria:


  • Cross-pollination potential. Tutorials that attract an interdisciplinary audience will be given preference. The proposals should highlight, when applicable, the tutorial potential to transfer knowledge from one discipline/area to another.
  • Interactivity. We will favor tutorials that aim to include hands-on experiences, collaborative approaches, and interactivity.

Proposals of tutorials presented at past events are allowed, although novelty is a plus.


Tutorial proposal content and format

Proposals for tutorials should be no more than three pages in length. Please try to use AAAI Author Kit to format your submission; the author kit is available at http://www.aaai.org/Publications/Templates/AuthorKit19.zip. However, using the AAAI Author Kit is not strictly required. Proposal submissions should include the following information:


  • Tutorial title, type, and summary. A short description (200 words) of the main objective of the tutorial to be published on the main ICWSM website. Please indicate the type of tutorial you are proposing: course, translation, or case study.
  • Names, affiliations, emails, and personal websites of the tutorial organizers. A main contact author should be specified. A typical proposal should include no more than three presenters (more people can be involved in the organization).
  • Duration. A short timeline description of how you plan to break down the material over 45 mins, 90 mins, or half-day. Please mention here the proposed duration, but keep in mind that the Tutorial Chairs might conditionally accept a proposal and suggest a different duration to best fit the organization of the whole event.
  • Tutorial schedule and activities. A description of the proposed tutorial format, a schedule of the proposed activities (e.g., presentations, interactive sessions) along with a *detailed* description for each of them.
  • Target audience, prerequisites and outcomes. A description of the target audience, the prerequisite skill set for the attendee (if any) as well as a brief list of goals for the tutors to accomplish by the end of the tutorial.
  • Materials. The organizers of accepted tutorials will be required to set up a web page containing all the information for the tutorial attendees before the tutorial day (roughly 2 weeks before the tutorial day). The proposal should contain the list of materials that will be made available on the website.
  • Precedent [when available]: A list of other tutorials held previously at related conferences, if any, together with a brief statement on how it follows-up on previous events. If the authors of the proposal have organized other tutorials in the past, pointers to the relevant material (e.g., slides, videos, web pages, code) should be provided.

Proposals should be submitted in PDF to the submission email (tutorials@icwsm.org). Pre-submission questions can be sent to the tutorials chairs (Jisun An, Sauvik Das and Shaomei Wu) at the same address (tutorials@icwsm.org).

Detailed Guidelines for Paper Submission

Content Guidelines

Format: Papers must be in high resolution PDF format, formatted for US Letter (8.5" x 11") paper, using Type 1 or TrueType fonts. Full papers are recommended to be 8 pages and must be at most 10 pages long, including references and any appendix. Revision papers and final camera-ready full papers can be up to 12 pages. Poster papers must be no longer than 4 pages, and demo descriptions must be no longer than 2 pages, and all must be submitted by the deadlines given above, and formatted in AAAI two-column, camera-ready style (templates can be found at https://www.aaai.org/Publications/Templates/AuthorKit21.zip). No source files (Word or LaTeX) are required at the time of submission for review; only the PDF file is permitted. Finally, the copyright slug may be omitted in the initial submission phase and no copyright form is required until a paper is accepted for publication.


Anonymity: ICWSM-2021 review is double-blind. Therefore, please anonymize your submission: do not put the author(s) names or affiliation(s) at the start of the paper, and do not include funding or other acknowledgments in papers submitted for review. References to authors' own prior relevant work should be included, but should not specify that this is the authors' own work. Citations to the author's own work should be anonymized, if possible, or can be added later to the final camera-ready version for publication. It is up to the authors' discretion how much to further modify the body of the paper to preserve anonymity. The requirement for anonymity does not extend outside of the review process, e.g. the authors can decide how widely to distribute their papers over the Internet before the program committee meeting. Even in cases where the author's identity is known to a reviewer, the double-blind process will serve as a symbolic reminder of the importance of evaluating the submitted work on its own merits without regard to authors' reputation. Note that 2-page demo submissions and the dataset paper submissions, and only these, are exempt from the anonymization requirement as they often contain system URLs or URLs to data sharing services.


Language: All submissions must be in English.


Revisions: Papers that were previously submitted to ICWSM and received a "Revise and Resubmit " decision should be accompanied by a copy of the previous reviews and an author response statement. The response statement may be in any format, but many reviewers appreciate a response that begins with an overall summary and then includes a table, with each row containing a reviewer comment in the left cell, and author's response in the right cell. The response cell may explain why no changes were made, or may describe changes and direct the reviewer to a particular page, section, or figure, where the revised content appears. At the discretion of the Senior PC member handling the paper, the revised version may be sent back to some or all of the original reviewers for comment and evaluation, and may also be sent to additional reviewers.


Optional publication for social sciences and sociophysics papers

Researchers who wish to submit full papers without publication in the conference proceedings, may designate their submission as 'social sciences and sociophysics (not for publication)'. Submissions must adhere to the formatting and content guidelines above. They will be reviewed according to the same process and criteria as all other full paper submissions. While we will not accept previously published papers, papers submitted as social sciences and sociophysics (not for publication) may be under review concurrently at a journal. Papers accepted to this track will be full presentations, integrated with the conference, but will be published only as abstracts in the ICWSM conference proceedings.


Submissions originally designated as not for publication cannot be converted at the end to publication in the ICWSM conference proceedings, because that would provide a mechanism enabling simultaneous consideration of the same paper for publication in two venues. Researchers who do wish to publish their papers in the ICWSM proceedings should submit to the regular track. All submitted papers, whether targeted for publication or not, will be judged according to the same acceptance criteria.


Duplicate Submission

ICWSM-2021 will not accept any paper that, at the time of submission, is under review for or has already been published or accepted for publication in a journal or conference. This restriction does not apply to submissions for non-archival workshops.


If duplicate submissions are identified during the review process then:

  • All submissions from that author will be disqualified from the current ICWSM conference;
  • And authors will not be permitted to submit papers to the ICWSM conference in the following year.

Conference Registration

Authors will be contacted about how to register for the conference. General registration for this year’s virtual conference will open soon. Stay tuned!


Publication

All accepted papers and extended abstracts will be published in the conference proceedings, except for those submitted to the 'social sciences and sociophysics (not for publication)'; only abstracts will be published for those. Though initial submissions of full papers must not exceed ten (10) pages, full papers accepted for publication will be allocated up to twelve (12) pages in the conference proceedings to facilitate to address comments raised by the reviewers. Authors will be required to transfer copyright to AAAI.


Datasets

ICWSM provides a service for hosting datasets pertaining to research presented at the conference. Authors of accepted papers will be encouraged to share the datasets on which their papers are based, while adhering to the terms and conditions of the data provider. Of these datasets, one will be selected for an award which will be based on the quality, scope, and timeliness of each dataset. More information will be available on our website.


Attending ICWSM-2021

The main conference will be held on 8th, 9th, and 10th June between 9:00 am - 3:00 pm Eastern Standard Time (2:00 pm to 8:00 pm British Standard Time), with a replay (featuring a mix of recorded and live sessions) for Asia (10:00 am China Standard Time).


Earlier this year, we circulated a survey among present and past authors about your preferences for a virtual conference. Based on the feedback we received from all of you, we have carefully planned this year’s virtual conference to be an accessible and rewarding experience for everyone.


There are two ways of enjoying the conference this year:


  • ICWSM Lite: The MiniConf and Slack experience. Similar to last year’s ICWSM, participants can choose a largely solo journey through the talks and events in ICWSM but still meet up with others through Slack and the Single-track events. There are limited opportunities to interact with paper authors, but you can always invite them to catch up on Slack!
  • ICWSM Deluxe: The Gathertown, MiniConf, and Slack experience. Enrich your conference experience by hanging out in a custom-designed green space, much like your favorite spot on campus. Walk to your next session with your friends. Ask questions of the authors of the papers you really dig. Bump into the keynote speakers on your way to the next session. Hang out with the organizing committee and ask all your burning questions. And when the sessions are over, unwind with new friends over a game of scribbl.

We're getting everything ready for you, so we appreciate your patience. Please do start exploring the keynotes, panels, and the list of accepted papers this year.

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 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.

Nomination Process and Eligibility

Both self-nominations and nominations 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.


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 computational social sciences or social computing in terms of their thematic and methods.
  3. Have published their research in the top venues for social computing or computational social science, including active participation in ICWSM.

Selection Process

The selection committee consists of three or more members and is appointed by the AAAI ICWSM Steering Committee Chair. The committee solicits nominations and self-nominations from the computational social science and social computing 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 behaviour, which may be quantitative or qualitative in nature. Depth and impact are valued over breadth of contribution for this award.


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.

ICWSM-2021 Keynote Address

All Paths From Blogs to Social Media Point to Need of Digital Governance

Virgilio Almeida (UFMG and Berkman Klein Center at Harvard University)


The list of governance challenges brought by digital technology is long and touches every aspect of modern life. Platforms such as Amazon, Uber, Google, Facebook, Linkedin, YouTube, and Twitter effectively control access to a wide variety of information, services, and products. Surveillance systems, algorithmic filtering of information, bias, discrimination, social and political rankings of citizens are a few examples of challenges of the digital world.


I will first focus on the structural level to discuss three digital governance problems that are worth highlighting, namely the multistakeholder nature of the Internet, the climate of growing global polarization and the rampant online misinformation. I will also discuss how computing research can stimulate the development of future policies and regulation for the digital world, with novel conceptions of governance using new technologies of distributed systems. This talk will suggest new opportunities to construct the future of digital governance, in a legitimate, inclusive, and secure use of digital resources to produce sustainable services and public policies for the online world.


Virgilio Almeida is a Professor Emeritus of Computer Science at the Federal University of Minas Gerais (UFMG). He is also Faculty Associate at the Berkman Klein Center at Harvard University. Virgilio received his PhD degree in Computer Science at Vanderbilt University, a Master's degree in computer science at PUC-Rio and a bachelor degree in Electrical Engineering from UFMG. He held visiting positions in several universities and research labs, such as Harvard University (School of Engineering and Applied Sciences), New York University, Boston University, Santa Fe Institute HP Labs. Professor Virgilio is the co-author of five books dealing Web technologies, e-commerce, performance modeling and capacity planning, published by Prentice Hall. His most recent book published by Palgrave MacMIllam is, "Governance for the Digital World." Virgilio was one of the commissioners of the Global Commission for the Stability of Cyberspace. His current research interests focus on social computing, governance of algorithms, modeling and analysis of large scale distributed systems.

Hate speech: Detection, Mitigation and Beyond

Abstract

Social media sites such as Twitter and Facebook have connected billions of people and given the opportunity to the users to share their ideas and opinions instantly. That being said, there are several ill consequences as well such as online harassment, trolling, cyber-bullying, fake news, and hate speech. Out of these, hate speech presents a unique challenge as it is deep engraved into our society and is often linked with offline violence. Social media platforms rely on local moderators to identify hate speech and take necessary action, but with a prolific increase in such content over social media many are turning toward automated hate speech detection and mitigation systems. This shift brings several challenges on the plate, and hence, is an important avenue to explore for the computation social science community.


In this translation style tutorial, we present an exposition of hate speech detection and mitigation in three steps. First, we shall describe the current state of research in the hate speech domain, focusing on different detection and mitigation systems that have developed over time. Next, we shall highlight the challenges that these systems might carry like bias and lack of transparency. The final section will concretize the path ahead, providing clear guidelines for the community working on hate speech and related areas. We shall outline the open challenges and research directions for interested researchers.


Here, we plan to cover the following topics, i) How is hate speech affecting different platforms? ii) Existing dataset, iii) Text-based hate speech systems, iv) User-based hate speech systems, v) How we can mitigate or slow down the process of spread of hate speech, vi) What are the challenges still present in the domain, e.g.: Explainability and bias, Multimodal and multilingual challenges etc, in the tutorial.

Engaging the Ethics of “Public” Data in Social Media Research

Abstract

This tutorial bridges social media research methods with concepts in ethics and privacy. Researchers studying the web and social media find themselves immersed in a domain where data flows freely and is often considered “public,” but that data is also potentially bound by contextual norms and expectations. While many research communities have engaged with the ethics of data collection, sharing, and retention practices, these debates are often less-visible to parts of the data and computational social science communities. In this tutorial, we will engage the concept of contextual integrity to provide space for the community to discuss how ethical risks emerge when engaging with “public” data, and offer practical methods for addressing this risk. This tutorial will bridge ongoing conversations in research ethics about practices of data collection and retention with emerging practices of data and computational social science researchers. Participants will gain practical methods for identifying, tracking, and mitigating ethical harms related to the collection and use of “public” data in web and social media research.

Knowledge In - Wisdom Out - Explainable Data for AI in Cyber Social Threats and Public Health

Abstract

In today's data-driven world, organizations derive insights from massive amounts of data through large scale statistical machine learning models. However, statistical techniques can be easy to fool with adversarial instances (a neural network can predict a non-extremist as an extremist by mere presence of the word Jihad), which raises question in Data Quality. In high stakes decision making problems, such as cyber social threats, it is highly sensitive to classify a non-extremist as an extremist and vice-versa. Data quality is good if the data possesses adequate domain coverage and the labels contain adequate semantics. For example, is the semantics of an extremist vs. non-extremist vis-a-vis the word Jihad captured in the label (adequate semantics in labels)? Also, are there enough non-extremists with the word Jihad in the training data from the perspective of religion, hate, or ideology? Thus semantic annotation of the data, beyond mere labels attached to data instances, can significantly improve the robustness of model outcomes and ensure that the model has learned from trustworthy, knowledge-guided data standards. It is important to note that the knowledge-guided standards help de-bias the data if specified correctly (contextualized de-biasing extremist behavior data from bias towards the word Jihad). Therefore, in addition to trust in the robustness of outcomes, knowledge guided data creation also enables fair and ethical practices during real-world deployment of machine learning in high stakes decision making. We denote such data as Explainable Data. In this tutorial of type course and case-studies, we detail how to construct Explainable Data using various expert resources and knowledge graphs. All the materials (resources and implementations) presented during the tutorial will be made available on: KIWO-ICWSM, a week before the tutorial. We plan a 90 minute tutorial (Intermediate Level) with 2 breaks (5 mins each).
