Do you (or someone you know) care about online communities and organizing, scientific research, education, and sharing ideas? We are looking for a person to join us and help grow our research and public impact. The (paid, part-time with benefits) position will focus on responsibilities such as research assistance, research administration, communications and outreach. 

This is a new position and will be the first dedicated staff member with the group. The person who takes the job will shape the role together with us based on their interests and skills.  While we have some ideas about the qualifications that might make somebody a compelling candidate (see below), we are eager to hear from anyone who is willing to get involved, learn on the job, and collaborate with us. You do not need to be an expert or have decades of experience to apply for this job. We aim to value and build on applicants’ experiences.

The position is about half time (25 hours per week) through Northwestern University and could be performed almost entirely remotely (the collective hosts in-person meetings and workshops when public health/safety allows). The salary will start at around $30,000 per year and includes excellent benefits through Northwestern. We’re looking for a minimum 1 year commitment.

Expected responsibilities will likely fall into three areas:

• Support research execution (example: develop materials to recruit study participants)
• Research administration (example: manage project tracking, documentation)
• Community management (example: plan meetings with partner organizations)

Candidates must hold at least a bachelor’s degree. Familiarity with scientific research, project management, higher education, and/or event planning is a plus, as is prior experience in the social or computer sciences, research organizations, online communities, and/or public interest technology and advocacy projects of any kind.

To learn more about the Community Data Science Collective, you should check out our wiki, read previous posts on this blog, and look at some of our recent publications. Please feel free to contact anyone in the group with questions. We are committed to creating a diverse, inclusive, equitable, and accessible work environment within our collective and we look forward to working with someone who shares these values.

Ready to apply? Please do so via this Northwestern University job posting.  We are reviewing applications on a rolling basis and hope to hire someone to begin later this summer.

As we do every year, members of the Community Data Science Collective will be presenting work at the International Communication Association (ICA)’s 71st Annual Conference which will take place virtually next week. Due to the asynchronous format of ICA this year, none of the talks will happen at specific times. Although the downside of the virtual conference is that we won’t be able to meet up with you all in person, the good news is that you’ll be able to watch our talks and engage with us on whatever timeline suits you best between May 27 and and 31st.

This year’s offerings from the collective include:

Nathan TeBlunthuis will be presenting work with Benjamin Mako Hill as part of the ICA Computational Methods section on “Time Series and Trends in Communication Research.” The name of their talk is “A Community Ecology Approach for Identifying Competitive and Mutualistic Relationships Between Online Communities.”

Aaron Shaw is presenting a paper on “Participation Inequality in the Gig Economy” on behalf of himself, Floor Fiers and Eszter Hargittai . The talk will be as part of a session organized by the ICA Communication and Technology section on “From Autism to Uber: The Digital Divide and Vulnerable Populations.”

Floor Fiers collaborated with Nathan Walter on a poster titled “Sharing Unfairly: Racial Bias on Airbnb and the Effect of Review Valence.” The poster is part of the interactive poster session of the ICA Ethnicity and Race section.

Nick Hager will be talking about his paper with Aaron Shaw titled “Randomly-Generated Inequality in Online News Communities,” which is part of a high density session on “Social Networks and Influence.”

Finally, Jeremy Foote will be chairing a session on “Cyber Communities: Conflicts and Collaborations” as part of the ICA Communication and Technology division.

We look forward to sharing our research and connecting with you at ICA!

UPDATE: The paper led by Nathan TeBlunthuis won the best paper award from the ICA Computational Methods section! Congratulations, Nate!

We try to keep this blog updated with new research and presentations from members of the group, but we often fall behind. With that in mind, this post is more of a listicle: 22 things you might not have seen from the CDSC in the past year! We’ve included links to (hopefully un-paywalled copies) of just about everything.

It’s Ph.D. application season and the Community Data Science Collective is recruiting! As always, we are looking for talented people to join our research group. Applying to one of the Ph.D. programs that the CDSC faculty members are affiliated with is a great way to do that.

This post provides a very brief run-down on the CDSC, the different universities and Ph.D. programs we’re affiliated with, and what we’re looking for when we review Ph.D. applications. It’s close to the deadline for some of our programs, but we hope this post will still be useful to prospective applicants now and in the future.

What is the Community Data Science Collective?

The Community Data Science Collective (or CDSC) is a joint research group of (mostly) quantitative social scientists and designers pursuing research about the organization of online communities, peer production, online communities, and learning and collaboration in social computing systems. We are based at Northwestern University, the University of Washington, Carleton College, the University of North Carolina, Chapel Hill, Purdue University, and a few other places. You can read more about us and our work on our research group blog and on the collective’s website/wiki.

What are these different Ph.D. programs? Why would I choose one over the other?

Although we have people at other places, this year the group includes four faculty principal investigators (PIs) who are actively recruiting PhD students: Aaron Shaw (Northwestern University), Benjamin Mako Hill (University of Washington in Seattle), Sayamindu Dasgupta (University of North Carolina at Chapel Hill), and Jeremy Foote (Purdue University). Each of these PIs advise Ph.D. students in Ph.D. programs at their respective universities. Our programs are each described below.

Although we often work together on research and serve as co-advisors to students in each others’ projects, each faculty person has specific areas of expertise and interests. The reasons you might choose to apply to one Ph.D. program or to work with a specific faculty member could include factors like your previous training, career goals, and the alignment of your specific research interests with our respective skills.

At the same time, a great thing about the CDSC is that we all collaborate and regularly co-advise students across our respective campuses, so the choice to apply to or attend one program does not prevent you from accessing the expertise of our whole group. But please keep in mind that our different Ph.D. programs have different application deadlines, requirements, and procedures!

Who is actively recruiting this year?

Given the disruptions and uncertainties associated with the COVID19 pandemic, the faculty PIs are more constrained in terms of whether and how they can accept new students this year. If you are interested in applying to any of the programs, we strongly encourage you to reach out the specific faculty in that program before submitting an application.

Ph.D. Advisors

Sayamindu Dasgupta is is an Assistant Professor in the School of Information and Library Science at UNC Chapel Hill. Sayamindu’s research focus includes data science education for children and informal learning online—this work involves both system building and empirical studies.

Benjamin Mako Hill is an Assistant Professor of Communication at the University of Washington. He is also an Adjunct Assistant Professor at UW’s Department of Human-Centered Design and Engineering (HCDE) and Computer Science and Engineering (CSE). Although many of Mako’s students are in the Department of Communication, he also advises students in the Department of Computer Science and Engineering, HCDE, and the Information School—although he typically has limited ability to admit students into those programs. Mako’s research focuses on population-level studies of peer production projects, computational social science, efforts to democratize data science, and informal learning.

Aaron Shaw is an Associate Professor in the Department of Communication Studies at Northwestern. In terms of Ph.D. programs, Aaron’s primary affiliations are with the Media, Technology and Society (MTS) and the Technology and Social Behavior (TSB) Ph.D. programs. Aaron also has a courtesy appointment in the Sociology Department at Northwestern, but he has not directly supervised any Ph.D. advisees in that department (yet). Aaron’s current research projects focus on comparative analysis of the organization of peer production communities and social computing projects, participation inequalities in online communities, and empirical research methods.

Jeremy Foote is an Assistant Professor at the Brian Lamb School of Communication at Purdue University. He is affiliated with the Organizational Communication and Media, Technology, and Society programs. Jeremy’s current research focuses on how individuals decide when and in what ways to contribute to online communities, and how understanding those decision-making processes can help us to understand which things become popular and influential. Most of his research is done using data science methods and agent-based simulations.

What do you look for in Ph.D. applicants?

There’s no easy or singular answer to this. In general, we look for curious, intelligent people driven to develop original research projects that advance scientific and practical understanding of topics that intersect with any of our collective research interests.

To get an idea of the interests and experiences present in the group, read our respective bios and CVs (follow the links above to our personal websites). Specific skills that we and our students tend to use on a regular basis include experience consuming and producing social science and/or social computing (human-computer interaction) research; applied statistics and statistical computing, various empirical research methods, social theory and cultural studies, and more.

Formal qualifications that speak to similar skills and show up in your resume, transcripts, or work history are great, but we are much more interested in your capacity to learn, think, write, analyze, and/or code effectively than in your credentials, test scores, grades, or previous affiliations. It’s graduate school and we do not expect you to show up knowing how to do all the things already.

Intellectual creativity, persistence, and a willingness to acquire new skills and problem-solve matter a lot. We think doctoral education is less about executing a task that someone else hands you and more about learning how to identify a new, important problem; develop an appropriate approach to solving it; and explain all of the above and why it matters so that other people can learn from you in the future. Evidence that you can or at least want to do these things is critical. Indications that you can also play well with others and would make a generous, friendly colleague are really important too.

All of this is to say, we do not have any one trait or skill set we look for in prospective students. We strive to be inclusive along every possible dimension. Each person who has joined our group has contributed unique skills and experiences as well as their own personal interests. We want our future students and colleagues to do the same.

Now what?

Still not sure whether or how your interests might fit with the group? Still have questions? Still reading and just don’t want to stop? Follow the links above for more information. Feel free to send at least one of us an email. We are happy to try to answer your questions and always eager to chat.

A few months ago we announced the launch of a COVID-19 Digital Observatory in collaboration with Pushshift and with funding from Protocol Labs. As part of this effort over the last several months, we have aggregated and published public data from multiple online communities and platforms. We’ve also been hard at work adding a series of new data sources that we plan to release in the near future.

More specifically, we have been gathering Search Engine Response Page (SERP) data on a range of COVID-19 related terms on a daily basis. This SERP data is drawn from both Bing and Google and has grown to encompass nearly 300GB of compressed data from four months of daily search engine results, with both PC and mobile results from nearly 500 different queries each day.

We have also continued to gather and publish revision and pageview data for COVID-related pages on English Wikipedia which now includes approximately 22GB of highly compressed data (several dozen gigabytes of compressed revision data each day) from nearly 1,800 different articles—a list that has been growing over time.

In addition, we are preparing releases of COVID-related data from Reddit and Twitter. We are almost done with two datasets from Reddit: a first one that includes all posts and comments from COVID-related subreddits, and a second that includes all posts or comments which include any of a set of COVID-related terms.

For the Twitter data, we are working out details of what exactly we will be able to release, but we anticipate including Tweet IDs and metadata for tweets that include COVID-related terms as well as those associated with hashtags and terms we’ve identified in some of the other data collection. We’re also designing a set of random samples of COVID-related Twitter content that will be useful for a range of projects.

In conjunction with these dataset releases, we have published all of the code to create the datasets as well as a few example scripts to help people learn how to load and access the data we’ve collected. We aim to extend these example analysis scripts in the future as more of the data comes online.

We hope you will take a look at the material we have been releasing and find ways to use it, extend it, or suggest improvements! We are always looking for feedback, input, and help. If you have a COVID-related dataset that you’d like us to publish, or if you would like to write code or documentation, please get in touch!

All of the data, code, and other resources are linked from the project homepage. To receive further updates on the digital observatory, you can also subscribe to our low traffic announcement mailing list.

Congratulations to Sohyeon Hwang, who will be awarded a prestigious Graduate Research Fellowship (a.k.a., GRFP) from the U.S. National Science Foundation!

The award will support Sohyeon’s proposed doctoral research on the complexity of governance practices in online communities. This work will focus on the ways communities heterogeneously fill the gap between rules-as-written (de jure) and rules-as-practiced (de facto) to impact the credibility and effectiveness of online governance work. The main components of this project will center around understanding the significance and role of shared (or conversely, localized) rules across communities; the automated tools utilized by these communities; and how users perceive, experience, and practice heterogeneity in online governance practices.

Sohyeon is a first year Ph.D. student in the Media, Technology & Society Program at Northwestern, advised by Aaron Shaw, and began working with the Community Data Science Collective last summer. She completed her undergraduate degree at Cornell University, where she double-majored in government and information science, focusing on Cold War era politics in the former and data science in the latter.

Sohyeon is currently pursuing graduate coursework, and her ongoing research includes a project comparing governance across several of the largest language editions of Wikipedia as well as work with Dr. Ágnes Horvát developing a project on multi-platform information spread. Recently, she has also taken a lead role in the efforts by CDSC and Pushshift to create a Digital Observatory for COVID-19 information resources.

The Community Data Science Collective, in collaboration with Pushshift and others, is launching a new collaborative project to create a digital observatory for socially produced COVID-19 information. The observatory has already begun the process of collecting, and aggregating public data from multiple online communities and platforms. We are publishing reworked versions of these data in forms that are well-documented and more easily analyzable by researchers with a range of skills and computation resources. We hope that these data will facilitate analysis and interventions to improve the quality of socially produced information and public health.

During crises such as the current COVID-19 pandemic, many people turn to the Internet for information, guidance, and help. Much of what they find is socially produced through online forums, social media, and knowledge bases like Wikipedia. The quality of information in these data sources varies enormously and users of these systems may receive information that is incomplete, misleading, or even dangerous. Efforts to improve this are complicated by difficulties in discovering where people are getting information and in coordinating efforts to focus on refining the more important information sources. There are number of researchers with the skills and knowledge to address these issues, but who may struggle to gather or process social data. The digital observatory facilitates data collection, access, and analysis.

Our initial release includes several datasets, code used to collect the data, and some simple analysis examples. Details are provided on the project page as well as our public Github repository. We will continue adding data, code, analysis, documentation, and more. We also welcome collaborators, pull-requests, and other contributions to the project.

What’s the goal for this project?

Our hope is that the public datasets and freely licensed tools, techniques, and knowledge created through the digital observatory will allow researchers, practitioners, and public health officials to more efficiently gather, analyze, understand, and act to improve these crucial sources of information during crises. Ultimately this will support ongoing responses to COVID-19 and contribute to future preparedness to respond to crisis events through analyses conducted after the fact.

How do I get access to the digital observatory?

The digital observatory data, code, and other resources will exist in a few locations, all linked from the project homepage. The data we collect, parse, and publish lives at covid19.communitydata.org/datasets. The code to collect, parse, and output those datasets lives in our Github repository, which also includes some scripts for getting started with analysis. We will integrate additional data and data collection resources from Pushshift and adjacent projects as we go. For more information, please check out the project page.

Stay up to date!

To receive updates on the digital observatory, please subscribe to our low traffic announcement mailing list. You will be the first to know about new datasets and other resources (and we won’t use or distribute addresses for any other reason).

Do online communities compete with each other over resources or niches? Do they co-evolve in symbiotic or even parasitic relationships? What insights can we gain by applying ecological models of collective behavior to the study of collaborative online groups?

We  are delighted to announce that a Community Data Science Collective (CDSC) team led by Nate TeBlunthuis and Jeremy Foote has just started work on a three-year grant from the U.S. National Science Foundation to study the ecological dynamics of online communities! Aaron Shaw and Benjamin Mako Hill are principal investigators for the grant.

The projects supported by the award will extend the study of peer production and online communities by analyzing how aspects of communities’ environments impact their growth, patterns of participation, and survival. The work draws on recent research on various biological systems, organizational ecology, and human computer interaction (HCI). In general, we adapt these approaches to inform quantitative and computational analysis of populations of peer production communities and other online organizations.

As a major goal, we want to explain the conditions under which certain ecological dynamics emerge versus when they do not. For example, prior work has suggested that communities interact in ways that are both competitive and mutalistic. But what leads two communities to become competitors and others to benefit each other?  We aim to understand when these patterns to arise. We are also interested in how community leaders might pursue effective strategies for survival given circumstances in the surrounding environment.

The grant promises to support a number of projects within the CDSC. Nate and Jeremy led the proposal writing as well as two key pilot studies that informed the development of the proposal. Other group members are now involved in planning and developing multiple studies under the grant.

The grant was awarded by the NSF Cyber-Human Systems (CHS) program within the Directorate for Information and Intellligent Systems (IIS) and the award is shared by Northwestern and the University of Washington (award numbers IIS-1910202 and IIS-1908850). 

We’ve published the description of the proposal that we submitted to the NSF, although some details will shift as we carry out the project. The best place to stay up-to-date about the work will be to follow [the CDSC Twitter account (@ComDataSci)or the CDSC blog.

It’s Ph.D. application season and the Community Data Science Collective is recruiting! As always, we are looking for talented people to join our research group. Applying to one of the Ph.D. programs that Aaron, Mako, Sayamindu, and Jeremy are affiliated with is a great way to do that.

Earlier this year, a team led by Kaylea Champion were announced as recipients of a generous grant from the Ford and Sloan Foundations to support research into into peer produced software infrastructure. Now that the project is moving forward in earnest, we’re thrilled to tell you about it.

The project is motivated by the fact that peer production communities have produced awesome free (both as in freedom and beer) resources—sites like Wikipedia that gather the world’s knowledge, and software like Linux that enables innovation, connection, commerce, and discovery. Over the last two decades, these resources have become key elements of public digital infrastructure that many of us rely on every day. However, some pieces of digital infrastructure we rely on most remain relatively under-resourced—as security vulnerabilities like Heartbleed in OpenSSL reveal. The grant from Ford and Sloan aims will support a research effort to understand how and why some software packages that are heavily used receive relatively little community support and maintenance.

We’re tackling this challenge by seeking to measure and model patterns of usage, contribution, and quality in a population of free software projects. We’ll then try to identify causes and potential solutions to the challenges of relative underproduction. Throughout, we’ll draw on both insight from the research community and on-the-ground observations from developers and community managers. We aim to create practical guidance that communities and software developers can actually use as well as novel research contributions. Underproduction is, appropriately enough, a challenge that has not gotten much attention from researchers previously, so we’re excited to work on it.

Although Kaylea Champion is leading the project, the team working on the project includes Benjamin Mako Hill, Aaron Shaw, and collective affiliate Morten Warncke-Wang who did pioneering work on underproduction in Wikipedia.
