\opening{Dear members of the search committee,
}
I am writing to apply for the position of Assistant Professor in the
Department of Information Systems at the University of Maryland,
Baltimore County. I am a postdoctoral research fellow in the School of
Information at the University of Michigan advised by Ceren Budak. I
completed my Ph.D. in the fall of 2021 in the Department of
Communication at the University of Washington (UW) and was advised by
Benjamin Mako Hill. My scholarship is about human-centered computing
and artificial intelligence.
% Contact
% information for my references Professors Ceren Budak, Benjamin Mako
% Hill, and Aaron Shaw follows my signature.
The core question of my scholarship is: ``When people organize around
a common interest using digital media, how do the media technologies
they use shape (and are shaped by) the practices and outcomes of their
efforts?'' This is important to me because people use digital media to
self-organize incredible collaborative and collective efforts, but
doing so often depends on the use of rapidly changing technology they
do not control and that can harm or under-support their efforts.
Therefore, much of my research focuses on digital environments such as
Wikipedia and Reddit that have afforded self-organizers considerable
flexibility to shape their technology and institute policies, As a
basis of comparison, some of my work looks at platforms, such as
Change.org, that do not. I use a broad toolkit of data science methods
in this work and I specialize in analyzing behavioral digital trace
data using big data systems, machine learning algorithms, causal
inference from observational data, and statistical methodology. I am
an innovator and emerging leader in such methods within the field of
communication --- the computational methods division of the
International Communication Association has honored my first-authored
work with top paper awards in three consecutive years.

% in a range of digital environments. Like Wikipedia and Reddit, some of
% these afford communities considerable technical and organizational
% flexibility.
% Questions of responsible data science are increasingly core to my
% work, as exemplified by my two writing samples. The first, titled
% ``\textit{Effects of Algorithmic Flagging on Fairness}'', is published
% in \textit{Proceedings of the ACM: Human-Computer Interaction: CSCW},
% and I discuss it in depth below. The second, under review with a
% ``minor revisions'' decision at the journal \textit{Communication
% Methods and Measures}, addresses an important problem in modern
% study designs in a broad range of social science which incorporate
% supervised machine learning tools for measuring unstructured data
% (e.g., to categorize social media posts as ``toxic''). The problem is
% that such tools are prone to measurement error that may be correlated
% with social categories. When input into statistical procedures,
% classification errors can cause misleading inferences. My article uses
% monte-carlo simulations to evaluate recently proposed methods for
% adjusting regression models to account for such forms of measurement
% error and introduces a new method that can use validation data to
% obtain a consistent estimator that is more precise than can be
% obtained using validation data alone. My future research plans,
% discussed below, are to continue developing this line of
% methodological research and to open an investigation into how
% generative models may restructure the ecosystem of online voluntary
% organizations.
As suited to my broad and multi-faceted research questions, I take a
pragmatic and pluralistic approach to scholarship that engages many
areas of social and behavioral science including organizational
sociology, communication, human-computer interaction, and computer
supported cooperative work. My first-authored research is published in
competitive and high-impact interdisciplinary outlets including the
\textit{ACM CHI Conference on Human Factors in Computing Systems
(CHI)} (25\% acceptance rate), \textit{International AAAI Conference
on Web and Social Media (ICWSM)} (17\% acceptance rate), and
\textit{Proceedings of the ACM: Human-Computer Interaction: Computer
Supported Cooperative Work (ACM CSCW)} (24\% acceptance
rate)\footnote{ACM CSCW changed from an archival conference into a
journal in 2020 and stopped publishing acceptance rates.}. I also
have a paper on how algorithmic bias contaminates social science
research and how this can be addressed under review with a ``minor
revisions'' decision at the journal \textit{Communication Methods and
Measures}. My ongoing projects continue targeting such outlets as
well as top general-science journals that publish social and
behavioral research.
My 2021 \textit{ACM CSCW} article, ``Effects of Algorithmic Flagging
on Fairness: Quasi-Experimental Evidence from Wikipedia'' exemplifies
how my scholarship brings together online communities and artificial
intelligence. I investigated how machine learning algorithms used by
platform moderators to flag harmful behavior shape the fairness of
their moderation actions. Algorithmic fairness research has uncovered
how models can learn spurious associations between social signifiers
(e.g., someone's skin color or use of a Wikipedia account) and
predicted outcomes (e.g., whether someone attends their court date or
vandalizes Wikipedia) in ways that risk amplifying social inequalities
when models are used to make decisions. Yet scholars in science and
technology studies have pointed out that focusing narrowly on
model-building as the location of problems and their solutions ignores
how social inequalities are sustained by broader social forces.
To understand how algorithmic flags shape the fairness of moderation
on Wikipedia, I used a regression discontinuity analysis to estimate
causal effects of flagging algorithms on moderation actions in several
Wikipedia language communities. Leading research groups at Carnegie
Mellon, École Polytechnique Fédérale de Lausanne (EPFL), and Meta have
already used the method that I developed in their AI Fairness,
Accountability, and Transparency research. I found that even though
the algorithm was biased against editors lacking important social
signals of trustworthiness on Wikipedia, algorithmic flagging made
moderation more fair to these editors because it helped moderators
find and correct misbehavior by apparently trustworthy users. This
demonstrates that AI technologies can be designed to promote equity in
ways that go beyond eliminating bias.

% For instance, in my class on innovation communities, students identify problems they

% without spoiling them. The students drew from and re-purposed strategies covered in

While previous work has documented the importance of manual content moderation, the effects of automated content moderation remain largely unknown. Here, in a large study of Facebook comments (n = 412M), we used a fuzzy regression discontinuity design to measure the impact of automated content moderation on subsequent rule-breaking behavior (number of comments hidden/deleted) and engagement (number of additional comments posted). We found that comment deletion decreased subsequent rule-breaking behavior in shorter threads (20 or fewer comments), even among other participants, suggesting that the intervention prevented conversations from derailing. Further, the effect of deletion on the affected user's subsequent rule-breaking behavior was longer-lived than its effect on reducing commenting in general, suggesting that users were deterred from rule-breaking but not from commenting. In contrast, hiding (rather than deleting) content had small and statistically insignificant effects. Our results suggest that automated content moderation increases adherence to community guidelines.},

Thus, a "successful'' online community often evokes an image of hundreds of thousands of users, and practitioners and researchers alike have sought to devise methods to achieve growth and thereby, success. On the other hand, small online communities exist in droves and many persist in their smallness over time. Turning to the highly popular discussion website Reddit, which is made up of hundreds of thousands of communities, we conducted a qualitative interview study examining how and why people participate in these persistently small communities, in order to understand why these communities exist when popular approaches would assume them to be failures. Drawing from twenty interviews, this paper makes several contributions: we describe how small communities provide unique informational and interactional spaces for participants, who are drawn by the hyperspecific aspects of the community; we find that small communities do not promote strong dyadic interpersonal relationships but rather promote group-based identity; and we highlight how participation in small communities is part of a broader, ongoing strategy to curate participants' online experience. We argue that online communities can be seen as nested niches: parts of an embedded, complex, symbiotic socio-informational ecosystem. We suggest ways that social computing research could benefit from more deliberate considerations of interdependence between diverse scales of online community sizes.},

abstract = {Attracting and retaining newcomers is critical and challenging for online production communities such as Wikipedia, both because volunteers need specialized training and are likely to leave before being integrated into the community. In response to these challenges, the Wikimedia Foundation started the Wiki Education Project (Wiki Ed), an online program in which college students edit Wikipedia articles as class assignments. The Wiki Ed program incorporates many components of institutional socialization, a process many conventional organizations successfully use to integrate new employees through formalized on-boarding practices. Research has not adequately investigated whether Wiki Ed and similar programs are effective ways to integrate volunteers in online communities, and, if so, the mechanisms involved. This paper evaluates the Wiki Ed program by comparing 16,819 student editors in 770 Wiki Ed classes with new editors who joined Wikipedia in the conventional way. The evaluation shows that the Wiki Ed students did more work, improved articles more, and were more committed to Wikipedia. For example, compared to new editors who joined Wikipedia in the conventional way they were twice as likely to still be editing Wikipedia a year after their Wiki Ed class was finished. Further, students in classrooms that encouraged joint activity, a key component of institutional socialization, produced better quality work than those in classrooms where students worked independently. These findings are consistent with an interpretation that the Wiki Ed program was successful because it incorporated elements of institutionalized socialization.},

Prior efforts to explain why some petitions are more successful than others emphasize signer motivations, petition framing, social media, or resources from movement organizations. We advance a key insight of organizational ecology: population-level variables like density and concentration also constrain success. We use latent Dirichlet allocation (LDA) topic models to measure overlap density and frame specialization. We then model how ecological dynamics affect petition signature counts. We observe density dependence: a curvilinear relationship between overlap density and success. We anticipated resource partitioning: specialists enjoy competitive advantages under concentration, but we find no evidence for it. We discuss boundary conditions for ecological dynamics commonly found in organizational fields induced by the distinctive scope of e-tactic platforms. Platforms may produce concentration without advantages for specialists by lowering entry costs for generalists and specialists alike.},

Reliance on these clues can lead to "overprofiling'' bias when moderators focus on these signals but overlook the misbehavior of others. We propose that algorithmic flagging systems deployed to improve the efficiency of moderation work can also make moderation actions more fair to these users by reducing reliance on social signals and making norm violations by everyone else more visible. We analyze moderator behavior in Wikipedia as mediated by RCFilters, a system which displays social signals and algorithmic flags, and estimate the causal effect of being flagged on moderator actions. We show that algorithmically flagged edits are reverted more often, especially those by established editors with positive social signals, and that flagging decreases the likelihood that moderation actions will be undone. Our results suggest that algorithmic flagging systems can lead to increased fairness in some contexts but that the relationship is complex and contingent.},

abstract = {Platforms often host multiple online groups with highly overlapping topics and members. How can researchers and designers understand how interactions between related groups affect measures of group health? Inspired by population ecology, prior social computing research has studied competition and mutualism among related groups by correlating group size with degrees of overlap in content and membership. The resulting body of evidence is puzzling as overlaps seem sometimes to help and other times to hurt. We suggest that this confusion results from aggregating inter-group relationships into an overall environmental effect instead of focusing on networks of competition and mutualism among groups. We propose a theoretical framework based on community ecology and a method for inferring competitive and mutualistic interactions from time series participation data. We compare population and community ecology analyses of online community growth by analyzing clusters of subreddits with high user overlap but varying degrees of competition and mutualism.},

abstract = {Organizing complex peer production projects and advancing scientific knowledge of open collaboration each depend on the ability to measure quality. Wikipedia community members and academic researchers have used article quality ratings for purposes like tracking knowledge gaps and studying how political polarization shapes collaboration. Even so, measuring quality presents many methodological challenges. The most widely used systems use quality assesements on discrete ordinal scales, but such labels can be inconvenient for statistics and machine learning. Prior work handles this by assuming that different levels of quality are ``evenly spaced'' from one another. This assumption runs counter to intuitions about degrees of effort needed to raise Wikipedia articles to different quality levels. I describe a technique extending the Wikimedia Foundations' ORES article quality model to address these limitations. My method uses weighted ordinal regression models to construct one-dimensional continuous measures of quality. While scores from my technique and from prior approaches are correlated, my approach improves accuracy for research datasets and provides evidence that the ``evenly spaced'' assumption is unfounded in practice on English Wikipedia. I conclude with recommendations for using quality scores in future research and include the full code, data, and models.},

abstract = {Automated classifiers (ACs), often built via supervised machine learning (SML), can categorize large, statistically powerful samples of data ranging from text to images and video, and have become widely popular measurement devices in communication science and related fields. Despite this popularity, even highly accurate classifiers make errors that cause misclassification bias and misleading results in downstream analyses-unless such analyses account for these errors. As we show in a systematic literature review of SML applications, communication scholars largely ignore misclassification bias. In principle, existing statistical methods can use "gold standard" validation data, such as that created by human annotators, to correct misclassification bias and produce consistent estimates. We introduce and test such methods, including a new method we design and implement in the R package misclassificationmodels, via Monte Carlo simulations designed to reveal each method's limitations, which we also release. Based on our results, we recommend our new error correction method as it is versatile and efficient. In sum, automated classifiers, even those below common accuracy standards or making systematic misclassifications, can be useful for measurement with careful study design and appropriate error correction methods.},

abstract = {Large-scale quantitative analyses have shown that individuals frequently talk to each other about similar things in different online spaces. Why do these overlapping communities exist? We provide an answer grounded in the analysis of 20 interviews with active participants in clusters of highly related subreddits. Within a broad topical area, there are a diversity of benefits an online community can confer. These include (a) specific information and discussion, (b) socialization with similar others, and (c) attention from the largest possible audience. A single community cannot meet all three needs. Our findings suggest that topical areas within an online community platform tend to become populated by groups of specialized communities with diverse sizes, topical boundaries, and rules. Compared with any single community, such systems of overlapping communities are able to provide a greater range of benefits.},

This study assesses the generalizability of Halfaker et al.'s influential 2013 paper on "The Rise and Decline of an Open Collaboration System." We replicate its tests of several theories related to newcomer retention and norm entrenchment using a dataset of hundreds of active peer production wikis from Wikia. We reproduce the subset of the findings from Halfaker and colleagues that we are able to test, comparing both the estimated signs and magnitudes of our models. Our results support the external validity of Halfaker et al.'s claims that quality control systems may limit the growth of peer production communities by deterring new contributors and that norms tend to become entrenched over time.},

abstract = {Machine learning-based predictive systems are increasingly used to assist online groups and communities in various content moderation tasks. However, there are limited quantitative understandings of whether and how different groups and communities use such predictive systems differently according to their community characteristics. In this research, we conducted a field evaluation of how content moderation systems are used in 17 Wikipedia language communities. We found that 1) larger communities tend to use predictive systems to identify the most damaging edits, while smaller communities tend to use them to identify any edit that could be damaging; 2) predictive systems are used less in content areas where there are more local editing activities; 3) predictive systems have mixed effects on reducing disparate treatment between anonymous and registered editors across communities of different characteristics. Finally, we discuss the theoretical and practical implications for future human-centered moderation algorithms.},

abstract = {Open collaboration platforms have fundamentally changed the way that knowledge is produced, disseminated, and consumed. In these systems, contributions arise organically with little to no central governance. Although such decentralization provides many benefits, a lack of broad oversight and coordination can leave questions of information poverty and skewness to the mercy of the system's natural dynamics. Unfortunately, we still lack a basic understanding of the dynamics at play in these systems and specifically, how contribution and attention interact and propagate through information networks. We leverage a large-scale natural experiment to study how exogenous content contributions to Wikipedia articles affect the attention that they attract and how that attention spills over to other articles in the network. Results reveal that exogenously added content leads to significant, substantial, and long-term increases in both content consumption and subsequent contributions. Furthermore, we find significant attention spillover to downstream hyperlinked articles. Through both analytical estimation and empirically informed simulation, we evaluate policies to harness this attention contagion to address the problem of information poverty and skewness. We find that harnessing attention contagion can lead to as much as a twofold increase in the total attention flow to clusters of disadvantaged articles. Our findings have important policy implications for open collaboration platforms and information networks.},
