abstract = "We introduce the problem of Task Assignment and
Sequencing, which models online optimization in expert
crowdsourcing settings that involve non-decomposable
macrotasks. Non-decomposition is a property of certain
types of complex problems, like the formulation of an
R\\&D approach or the definition of a research
methodology, which cannot be handled through the
``divide-and-conquer'' approach typically used in
microtask crowdsourcing. In contrast to splitting the
macrotask to multiple microtasks and allocating them to
several workers in parallel, our model supports the
sequential improvement of the macrotask one worker at a
time, across distinct time slots of a given timeline,
until a sufficient quality level is achieved. Our model
assumes an online environment where expert workers are
available only at specific time slots and worker/task
arrivals are not known a priori. With respect to this
setting, we propose TAS-ONLINE, an online algorithm
that aims to complete as many tasks as possible within
budget, required quality, and a given timeline, without
any future input information regarding job release
dates or worker availabilities. Experimental results
comparing TAS-ONLINE to five benchmarks show that it
achieves more completed jobs, lower flow times, and
higher job quality. This work bears practical
implications for providing performance and quality
guarantees to expert crowdsourcing platforms that wish
to integrate non-decomposable macrotasks into their
offered services.",

a systematic methodological study of controversy
detection by using the content and the network
structure of social media. Unlike previous work, rather
than studying controversy in a single hand-picked topic
and using domain-specific knowledge, we take a general
approach to study topics in any domain. Our approach to
quantifying controversy is based on a graph-based
three-stage pipeline, which involves (i) building a
conversation graph about a topic, (ii) partitioning the
conversation graph to identify potential sides of the
controversy, and (iii) measuring the amount of
controversy from characteristics of the graph. We
perform an extensive comparison of controversy
measures, different graph-building approaches, and data
sources. We use both controversial and
non-controversial topics on Twitter, as well as other
external datasets. We find that our new
random-walk-based measure outperforms existing ones in
capturing the intuitive notion of controversy and show
that content features are vastly less helpful in this

ConsensUs, a novel visualization tool that highlights
disagreement by asking group members to quantify their

evaluate this approach, we conducted a between-subjects

a group decision: written discourse only, visualization
only, and written discourse plus visualization. We
confirmed that the visualization helped participants
identify disagreements within the group and then
measured subsequent changes to their individual
opinions. The results show that disagreement
highlighting led participants to align their ratings
more with the opinions of other group members. While
disagreement highlighting led to better score
alignment, participants reported a number of reasons
for shifting their score, from genuine consensus to
appeasement. We discuss further research angles to
understand how disagreement highlighting affects social

abstract = "It has been observed that different media outlets
exert bias in the way they report the news, which
seamlessly influences the way that readers' knowledge
is built through filtering what we read. Therefore,
understanding bias in news media is fundamental for
obtaining a holistic view of a news story. Traditional
work has focused on biases in terms of ``agenda
setting,'' where more attention is allocated to stories
that fit their biased narrative. The corresponding
method is straightforward, since the bias can be
detected through counting the occurrences of different
stories/themes within the documents. However, these
methods are not applicable to biases which are implicit
in wording, namely, ``framing'' bias. According to
framing theory, biased communicators will select and
emphasize certain facts and interpretations over others
when telling their story. By focusing on facts and
interpretations that conform to their bias, they can
tell the story in a way that suits their narrative.
Automatic detection of framing bias is challenging
since nuances in the wording can change the
interpretation of the story. In this work, we aim to
investigate how the subtle pattern hidden in language
use of a news agency can be discovered and further
leveraged to detect frames. In particular, we aim to
identify the type and polarity of frame in a sentence.
Extensive experiments are conducted on real-world data
from different countries. A case study is further
provided to reveal possible applications of the
proposed method.",

increased user activity, motivation, and engagement to
large-scale scientific projects. However, there is an
ongoing debate about whether or not gamifying systems
such as these is actually an effective means by which
to increase motivation and engagement in the long term.
While gamification itself is receiving a large amount
of attention, there has been little beyond individual
studies to assess its suitability or success for
citizen science; similarly, while frameworks exist for
assessing citizen science performance, they tend to
lack any appreciation of the effects that game elements
might have had. We therefore review the literature to
determine what the trends are regarding the performance
of particular game elements or characteristics in
citizen science, and survey existing projects to assess
how popular different game features are. Investigating
this phenomenon further, we then present the results of
a series of interviews carried out with the EyeWire
citizen science project team to understand more about
how gamification elements are introduced, monitored,
and assessed in a live project. Our findings suggest
that projects use a range of game elements with points
and leaderboards the most popular, particularly in
projects that describe themselves as ``games.''
Currently, gamification appears to be effective in
citizen science for maintaining engagement with
existing communities, but shows limited impact for
attracting new players.",

ratings) and implicit feedback (e.g., browsing history,
click logs), which are both useful for improving
recommendations. However, as far as we are concerned,
no existing works have integrated both explicit and
multiple implicit feedback simultaneously. Therefore,
we propose a unified and flexible model, named Multiple
Feedback-based Personalized Ranking (MFPR), to make
full use of multiple feedback, which uses a
personalized ranking framework. To train model MFPR, we
design an algorithm to generate ordered item pairs as
labeled data, with consideration of both rating scores
and multiple implicit feedback. Extensive experiments
on two real-world datasets validate the effectiveness
of the MFPR model. With the integration of multiple
feedback, MFPR significantly improves recommendation

negative feedback, presumably to fix errors, whereas
students who had peer support did not. Two experiments
in which Mechanical Turk workers edited Wikipedia

information infrastructure constituted by the actions

is not a social computing technology a priori; instead
to emerge as one, much effort and work is required to
radically transform existing domains, including
wrestling with traditions, standards, and legacy. In
this article, we expand on previous work on Blockchain
as an information infrastructure, and on the notion of
infrastructural grind. Infrastructural grind allows us
to analytically explore how the emerging Blockchain
technology is appropriated into established business
domains, in our case the shipping industry. We present
ethnographic data unpacking three different accounts of
infrastructural grind taking place at the intersection
of the shipping and the Blockchain information
infrastructures. The results demonstrate that
infrastructural grind occurs as a result of various
infrastructuring activities taking place at different
intersections between the two infrastructures and is
constituted of the sum of these activities. We propose
a framework in which infrastructural grind is
constituted of three entangled dimensions:
permeability, interoperability, and velocity. These
socio-technical dimensions relate to infrastructural
properties such as legacy, embeddedness, and standards,
as well as to technical properties of specific
solutions deployed at specific points of
infrastructural grind. Our analysis shows that these
dimensions are enacted differently along the shipping
supply chain, and depending on the dynamic interplay
between them at various points of infrastructural
grind. At different points in time, the infrastructural
grind between Blockchain and the shipping domain will
thus manifest itself differently and at differential
velocity.",

characteristics, such as interests and political views,
that can be exploited to identify and track them, thus
raising privacy and identity concerns in online
communities. In this article, we investigate the
problem of user identity linkage on two behavior
datasets collected from different experiments.
Specifically, we focus on user linkage based on users'
interaction behaviors with respect to content topics.
We propose an embedding method to model a topic as a
vector in a latent space to interpret its deep
semantics. Then a user is modeled as a vector based on
his or her interactions with topics. The embedding
representations of topics are learned by optimizing the
joint-objective: the compatibility between topics with
similar semantics, the discriminative abilities of
topics to distinguish identities, and the consistency
of the same user's characteristics from two datasets.
The effectiveness of our method is verified on
real-life datasets and the results show that it
outperforms related methods. We also analyze failure
cases in the application of our identity linkage
method. Our analysis shows that factors such as the
visibility and variance of user behaviors and users'
group psychology can result in mis-linkages. We also
analyze the details of the behaviors of some
representative users to understand the essential
reasons for their identity being mis-linked. We find
that these users have high variance level in their
behaviors. According to the above experimental results,
we introduce a confidence score into identity linkage

abstract = "Participation by product users is critical to success
in free, open-source software (FOSS) software
communities as they originate and develop valuable
ideas for product innovation that are unlikely to
originate from the core software development community.
Users tend to be involved at the periphery of FOSS
communities, suggesting new product ideas, highlighting
problems with user documentation, or explaining when
the product design fails to fit with the needs of their
local user application domain. As an increasing number
of FOSS projects employ a hybrid participation model
that combines volunteer effort with paid software
development effort or product support, it can be
difficult for non-developer users to participate in
product innovation. In colocated organizations, it is
theorized that peripheral participants learn how to
engage with the practices and cultural identity of a
community through a sociocultural apprenticeship known
as legitimate peripheral participation. But we have
little literature that explores how legitimate
peripheral participation is enabled in online
communities. The research study presented in this
article explores how participation by peripheral users
in a hybrid FOSS project is afforded by participation
architecture channels and community mechanisms that
mediate two forms of engagement: a ``cognitive
apprenticeship'' that introduces participants to
situated domain activity, such as the community
processes involved in product innovation, and a
``social apprenticeship'' by which participants become
enculturated in the system of meanings, values, norms,
and behaviors that govern community/participant
identity. We identified five stages of community
innovation, analyzing sociotechnical affordances of the
online participation architecture that enable
peripheral participants to internalize the meanings of
community practice and to develop a social identity
within the FOSS community. Our contribution to theory
is provided by the substantive explanation of the
cognitive and social translations that enable
legitimate peripheral participation in online
communities, mediated by sociotechnical access channels
and mechanisms that afford two contrasting forms of
opportunities for action: those resulting from
interactions between a goal-oriented actor and the
technology platform features or channels of
participation, and those associated with the social
structures, roles, and relationships underpinning
community interactions. Neither of these is sufficient
without the other. Our contribution to practice is
provided by an explanation of how four distinct
categories of affordance provide these cognitive and
social apprenticeship benefits, allowing participation
architecture designers to cater to all forms of
peripheral user participation. We conclude that the
technical affordances of a typical FOSS community
participation architecture are insufficient to mediate
peripheral participation by nontechnical users.
Meaningful participation is mediated by interactions
between boundary spanners who play knowledge-brokering
and organizational bridging roles. The combination of
technical and social affordances enables peripheral
participants to acquire an interior view of community
practices and social culture and in turn to introduce
new ideas, new values, and new rationales to produce a
generative dance of innovation that percolates through
the community.",

psychometric user profiling has emerged as an effective
way of reaching individuals who are predisposed to

This article argues that in the case of political
advertising, this may present a democratic and ethical
challenge. Hypertargeting methods such as psychometrics
can ``crowd out'' political communication with opposing
views due to individual attention and time limitations,
creating inequities in the access to information
essential for voting decisions. The use of
psychometrics also appears to have been used to spread
both information and misinformation through social
media in recent elections in the U.S. and Europe. This
article is an applied ethics study of these methods in
the context of democratic processes and compared to
purely commercial situations. The ethical approach is
based on the theoretical, contractarian work of John
Rawls, which serves as a lens through which the author
examines whether the rights of individuals, as Rawls
attributes them, are violated by this practice. The
article concludes that within a Rawlsian framework, use
of psychometrics in commercial advertising on social
media platforms, though not immune to criticism, is not
necessarily unethical. In a democracy, however, the
individual cannot abandon the consumption of political
information, and since using psychometrics in political
campaigning makes access to such information unequal,
it violates Rawlsian ethics and should be regulated.",

collect the results once the workers complete them.
Currently, these systems provide limited guarantees
over the execution time, which is problematic for many
applications. Timely completion may even be impossible
to guarantee due to factors specific to the
crowdsourcing platform, such as the availability of
workers and concurrent tasks. In our previous work, we
presented the architecture of a crowd-powered system
that reshapes the interaction mechanism with the crowd.
Specifically, we studied a push-crowdsourcing model
whereby the workers receive tasks instead of selecting
them from a portal. Based on this interaction model, we
employed scheduling techniques similar to those found
in distributed computing infrastructures to automate
the task assignment process. In this work, we first
devise a generic scheduling strategy that supports both
fairness and deadline-awareness. Second, to complement
the proof-of-concept experiments previously performed
with the crowd, we present an extensive set of
simulations meant to analyze the properties of the
proposed scheduling algorithms in an environment with
thousands of workers and tasks. Our experimental
results show that, by accounting for human factors,

topics on Question-and-Answer (Q\&A) instances.
However, not all instances and topics receive the same
amount of attention, as some thrive and achieve
self-sustaining levels of activity, while others fail
to attract users and either never grow beyond being a
small niche community or become inactive. Hence, it is
imperative to not only better understand but also to
distill deciding factors and rules that define and

community managers with quantitative methods for them
to better understand, control, and foster their

activity-based time series from 50 randomly selected

characterize user behavior. We find four distinct types
of user activity temporal patterns, which vary
primarily according to the users' activity frequency.
Finally, by breaking down total activity in our 50 Q\&A
instances by the previously identified user activity
profiles, we classify those 50 Q\&A instances into
three different activity profiles. Our parsimonious
categorization of Q\&A instances aligns with the stage
of development and maturity of the underlying
communities, and can potentially help operators of such

abstract = "Many network scientists have investigated the problem
of mitigating or removing false information propagated
in social networks. False information falls into two
broad categories: disinformation and misinformation.
Disinformation represents false information that is
knowingly shared and distributed with malicious intent.
Misinformation in contrast is false information shared
unwittingly, without any malicious intent. Many
existing methods to mitigate or remove false
information in networks concentrate on methods to find
a set of seeding nodes (or agents) based on their
network characteristics (e.g., centrality features) to
treat. The aim of these methods is to disseminate
correct information in the most efficient way. However,
little work has focused on the role of uncertainty as a
factor in the formulation of agents' opinions.
Uncertainty-aware agents can form different opinions
and eventual beliefs about true or false information
resulting in different patterns of information
diffusion in networks. In this work, we leverage an
opinion model, called Subjective Logic (SL), which
explicitly deals with a level of uncertainty in an
opinion where the opinion is defined as a combination
of belief, disbelief, and uncertainty, and the level of
uncertainty is easily interpreted as a person's
confidence in the given belief or disbelief. However,
SL considers the dimension of uncertainty only derived
from a lack of information (i.e., ignorance), not from
other causes, such as conflicting evidence. In the era
of Big Data, where we are flooded with information,
conflicting information can increase uncertainty (or
ambiguity) and have a greater effect on opinions than a
lack of information (or ignorance). To enhance the
capability of SL to deal with ambiguity as well as
ignorance, we propose an SL-based opinion model that
includes a level of uncertainty derived from both
causes. By developing a variant of the
Susceptible-Infected-Recovered epidemic model that can
change an agent's status based on the state of their
opinions, we capture the evolution of agents' opinions
over time. We present an analysis and discussion of
critical changes in network outcomes under varying
values of key design parameters, including the
frequency ratio of true or false information
propagation, centrality metrics used for selecting
seeding false informers and true informers, an opinion
decay factor, the degree of agents' prior belief, and
the percentage of true informers. We validated our
proposed opinion model using both the synthetic network
environments and realistic network environments
considering a real network topology, user behaviors,
and the quality of news articles. The proposed agent's
opinion model and corresponding strategies to deal with
false information can be applicable to combat the
spread of fake news in various social media platforms
(e.g., Facebook).",

badges on top of financial remuneration. Our analysis
focuses on a particular type of incentive, contests, as
a means to apply crowdsourcing in near-real-time

model crowdsourcing contests as a continuous-time
Markov chain with the objective to maximise the output
of the crowd workers, while varying a parameter that
determines whether a worker is eligible for a reward
based on their present rank on the leaderboard. We
conduct empirical experiments in which crowd workers
recruited from CrowdFlower carry out annotation
microtasks on Wordsmith-in our case, to identify named
entities in a stream of Twitter posts. In the
experimental conditions, we test different reward
spreads and record the total number of annotations
received. We compare the results against a control
condition in which the same annotation task was
completed on CrowdFlower without a time or contest
constraint. The experiments show that rewarding only
the best contributors in a live contest could be a
viable model to deliver results faster, though quality
might suffer for particular types of annotation tasks.
Increasing the reward spread leads to more work being
completed, especially by the top contestants. Overall,
the experiments shed light on possible design
improvements of paid microtasks platforms to boost task
performance and speed and make the overall experience

abstract = "Crowd employment is a new form of short-term and
flexible employment that has emerged during the past
decade. To understand this new form of employment, it
is crucial to illuminate the underlying motivations of
the workforce involved in it. This article introduces
the Multidimensional Crowdworker Motivation Scale
(MCMS), a scale for measuring the motivation of
crowdworkers on microtask platforms. The MCMS is
theoretically grounded in self-determination theory and
tailored specifically to the context of paid
crowdsourced microlabor. The scale measures the
motivation of crowdworkers along six motivational
dimensions, ranging from amotivation to intrinsic
motivation. We validated the MCMS on data collected in
ten countries and three income groups. Factor analyses
demonstrated that the MCMS's six dimensions showed good
model fit, validity, and reliability. Furthermore, our
measurement invariance tests showed that motivations
measured with the MCMS are comparable across countries
and income groups, and we present a first cross-country
comparison of crowdworker motivations. This work
constitutes an important first step toward
understanding the motivations of the international
crowd workforce.",

knowledge and make important decisions in diverse areas
from health and finance to computing and data science.
Online discussion groups exhibit unique group dynamics
not found in traditional small groups, such as
staggered participation and asynchronous communication,
and the effects of these features on knowledge sharing
is not well understood. In this article, we focus on
one such aspect: wide variation in group size. Using a
controlled experiment with a hidden profile task, we
evaluate online discussion groups' capacity to share
distributed knowledge when group size ranges from 4 to
32 participants. We found that individuals in
medium-sized discussions performed the best, and we
suggest that this represents a tradeoff in which larger
groups tend to share more facts, but have more
difficulty than smaller groups at resolving
misunderstandings.",

abstract = "The increasing size of datasets with which researchers
in a variety of domains are confronted has led to a
range of creative responses, including the deployment
of modern machine learning techniques and the advent of
large scale ``citizen science projects.'' However, the
ability of the latter to provide suitably large
training sets for the former is stretched as the size
of the problem (and competition for attention amongst
projects) grows. We explore the application of
unsupervised learning to leverage structure that exists
in an initially unlabelled dataset. We simulate
grouping similar points before presenting those groups
to volunteers to label. Citizen science labelling of
grouped data is more efficient, and the gathered labels
can be used to improve efficiency further for labelling
future data. To demonstrate these ideas, we perform
experiments using data from the Pan-STARRS Survey for
Transients (PSST) with volunteer labels gathered by the
Zooniverse project, Supernova Hunters and a simulated
project using the MNIST handwritten digit dataset. Our
results show that, in the best case, we might expect to
reduce the required volunteer effort by 87.0\% and
92.8\% for the two datasets, respectively. These
results illustrate a symbiotic relationship between
machine learning and citizen scientists where each
empowers the other with important implications for the
design of citizen science projects in the future.",

that subject-matter-experts play in these knowledge
production settings has largely been left in a
theoretical and empirical void; its existence has been
assumed, but we know little about its nature and scope,
as it is difficult to observe. In this article, we
start filling that void, using Wikipedia as the setting
for our empirical investigation. First, we carefully
crossed information from individual Wikipedia editor
pages with external sources such as Google Scholar to
reliably identify editors who are credentialed experts.
Matching these credentialed experts with their
Wikipedia editing patterns, we used this dataset to
train a machine learning classifier that we then
employed to identify additional expert editors and
assess the nature and the scope of their work across
Wikipedia. Our results suggest that the scope of expert
involvement is substantial, albeit with considerable
differences across topics. We estimate that
approximately 10\%--30\% of Wikipedia s contributors
have substantial subject-matter expertise in the topics
that they edit. We discuss implications for theory and
practice of peer-production.",
