Extroverts Tweet Differently from Introverts in Weibo
Being dominant factors driving the human actions, personalities can be
excellent indicators in predicting the offline and online behavior of different
individuals. However, because of the great expense and inevitable subjectivity
in questionnaires and surveys, it is challenging for conventional studies to
explore the connection between personality and behavior and gain insights in
the context of large amount individuals. Considering the more and more
important role of the online social media in daily communications, we argue
that the footprint of massive individuals, like tweets in Weibo, can be the
inspiring proxy to infer the personality and further understand its functions
in shaping the online human behavior. In this study, a map from self-reports of
personalities to online profiles of 293 active users in Weibo is established to
train a competent machine learning model, which then successfully identifies
over 7,000 users as extroverts or introverts. Systematical comparisons from
perspectives of tempo-spatial patterns, online activities, emotion expressions
and attitudes to virtual honor surprisingly disclose that the extrovert indeed
behaves differently from the introvert in Weibo. Our findings provide solid
evidence to justify the methodology of employing machine learning to
objectively study personalities of massive individuals and shed lights on
applications of probing personalities and corresponding behaviors solely
through online profiles.Comment: Datasets of this study can be freely downloaded through:

Predicting Personality from Book Preferences with User-Generated Content Labels
Psychological studies have shown that personality traits are associated with
book preferences. However, past findings are based on questionnaires focusing
on conventional book genres and are unrepresentative of niche content. For a
more comprehensive measure of book content, this study harnesses a massive
archive of content labels, also known as 'tags', created by users of an online
book catalogue, Goodreads.com. Combined with data on preferences and
personality scores collected from Facebook users, the tag labels achieve high
accuracy in personality prediction by psychological standards. We also group
tags into broader genres, to check their validity against past findings. Our
results are robust across both tag and genre levels of analyses, and consistent
with existing literature. Moreover, user-generated tag labels reveal unexpected
insights, such as cultural differences, book reading behaviors, and other
non-content factors affecting preferences. To our knowledge, this is currently
the largest study that explores the relationship between personality and book
content preferences
Development and Maintenance of Self-Disclosure on Facebook: The Role of Personality Traits
This study explored the relationships between Facebook self-disclosure and personality traits in a sample of Italian users.
The aim was to analyze the predictive role of Big Five personality traits on different parameters of breadth and depth of selfdisclosed
behaviors online. Facebook users, aged between 18 and 64 years of age (Mage = 25.3 years, SD = 6.8; N = 958),
of which 51% were female, voluntarily completed an online survey assessing personality traits and Facebook self-disclosure.
Results at a series of hierarchical regression analyses significantly corroborated the hypotheses that high extroverted and
openness people tend to disclose on Facebook a significant amount of personal information, whereas high consciousness
and agreeableness users are less inclined to do it. Furthermore, more extroverts and agreeableness people develop less
intimacy on Facebook, differently from those with high levels of openness. Results also corroborated the hypothesis of a
full mediation of time usage in the relationship between personality factors such as extroversion and conscientiousness with
breadth of Facebook self-disclosure. Overall, according to the findings of the current study, personality traits and Facebook
self-disclosure become central both as predictive variables for depicting the different profiles of potential addicted and as
variables to help educators, teachers, and clinicians to develop training or therapeutic programs aimed at preventing the risk
of Internet addiction. Limitations of the study are discussed, and directions for future research are suggested
Towards Psychometrics-based Friend Recommendations in Social Networking Services
Two of the defining elements of Social Networking Services are the social
profile, containing information about the user, and the social graph,
containing information about the connections between users. Social Networking
Services are used to connect to known people as well as to discover new
contacts. Current friend recommendation mechanisms typically utilize the social
graph. In this paper, we argue that psychometrics, the field of measuring
personality traits, can help make meaningful friend recommendations based on an
extended social profile containing collected smartphone sensor data. This will
support the development of highly distributed Social Networking Services
without central knowledge of the social graph.Comment: Accepted for publication at the 2017 International Conference on AI &

Big-Five Personality Prediction Based on User Behaviors at Social Network Sites
Many customer services are already available at Social Network Sites (SNSs),
including user recommendation and media interaction, to name a few. There are
strong desires to provide online users more dedicated and personalized services
that fit into individual's need, usually strongly depending on the inner
personalities of the user. However, little has been done to conduct proper
psychological analysis, crucial for explaining the user's outer behaviors from
their inner personality. In this paper, we propose an approach that intends to
facilitate this line of research by directly predicting the so called Big-Five
Personality from user's SNS behaviors. Comparing to the conventional
inventory-based psychological analysis, we demonstrate via experimental studies
that users' personalities can be predicted with reasonable precision based on
their online behaviors. Except for proving some former behavior-personality
correlation results, our experiments show that extraversion is positively
related to one's status republishing proportion and neuroticism is positively
related to the proportion of one's angry blogs (blogs making people angry).Comment: 7 pages, predicting user's Big-five personality based on Social

Inferring Human Traits From Facebook Statuses
This paper explores the use of language models to predict 20 human traits
from users' Facebook status updates. The data was collected by the
myPersonality project, and includes user statuses along with their personality,
gender, political identification, religion, race, satisfaction with life, IQ,
self-disclosure, fair-mindedness, and belief in astrology. A single
interpretable model meets state of the art results for well-studied tasks such
as predicting gender and personality; and sets the standard on other traits
such as IQ, sensational interests, political identity, and satisfaction with
life. Additionally, highly weighted words are published for each trait. These
lists are valuable for creating hypotheses about human behavior, as well as for
understanding what information a model is extracting. Using performance and
extracted features we analyze models built on social media. The real world
problems we explore include gendered classification bias and Cambridge
Analytica's use of psychographic models.Comment: Submitted to the International Conference on Social Informatics 201
Identifying Social Satisfaction from Social Media
We demonstrate the critical need to identify social situation and instability
factors by acquiring public social satisfaction in this research. However,
subject to the large amount of manual work cost in subject recruitment and data
processing, conventional self-reported method cannot be implemented in real
time or applied in large scale investigation. To solve the problem, this paper
proposed an approach to predict users' social satisfaction, especially for the
economy-related satisfaction based on users' social media records. We recruited
2,018 Cantonese active participants from each city in Guangdong province
according to the population distribution. Both behavioral and linguistic
features of the participants are extracted from the online records of social
media, i.e., Sina Weibo. Regression models are used to predict Sina Weibo
users' social satisfaction. Furthermore, we consult the economic indexes of
Guangdong in 2012, and calculate the correlations between these indexes and the
predicted social satisfaction. Results indicate that social satisfaction can be
significantly expressed by specific social media features; local economy
satisfaction has significant positive correlations with several local economy
indexes, which supports that it is reliable to predict social satisfaction from
social media.Comment: 8 pages, 2 figure
Confiding in and Listening to Virtual Agents: The Effect of Personality
We present an intelligent virtual interviewer that engages with a user in a
text-based conversation and automatically infers the user's psychological
traits, such as personality. We investigate how the personality of a virtual
interviewer influences a user's behavior from two perspectives: the user's
willingness to confide in, and listen to, a virtual interviewer. We have
developed two virtual interviewers with distinct personalities and deployed
them in a real-world recruiting event. We present findings from completed
interviews with 316 actual job applicants. Notably, users are more willing to
confide in and listen to a virtual interviewer with a serious, assertive
personality. Moreover, users' personality traits, inferred from their chat
text, influence their perception of a virtual interviewer, and their
willingness to confide in and listen to a virtual interviewer. Finally, we
discuss the implications of our work on building hyper-personalized,
intelligent agents based on user traits
The effect of personality on collaborative task performance and interaction
Collocated, multi-user technologies, which support group-work are becoming increasingly popular. Examples include MERL's Diamondtouch and Microsoft's Surface, both of which have evolved from research prototypes to commercial products. Many applications have been developed for such technologies which support the work and entertainment needs of small groups of people. None of these applications however, have been studied in terms of the interactions and performances of their users with regards to their personality. In this paper, we address this research gap by conducting a series of user studies involving dyads working on a number of multi-user applications on the DiamondTouch tabletop device
Current Challenges and Visions in Music Recommender Systems Research
Music recommender systems (MRS) have experienced a boom in recent years,
thanks to the emergence and success of online streaming services, which
nowadays make available almost all music in the world at the user's fingertip.
While today's MRS considerably help users to find interesting music in these
huge catalogs, MRS research is still facing substantial challenges. In
particular when it comes to build, incorporate, and evaluate recommendation
strategies that integrate information beyond simple user--item interactions or
content-based descriptors, but dig deep into the very essence of listener
needs, preferences, and intentions, MRS research becomes a big endeavor and
related publications quite sparse.
The purpose of this trends and survey article is twofold. We first identify
and shed light on what we believe are the most pressing challenges MRS research
is facing, from both academic and industry perspectives. We review the state of
the art towards solving these challenges and discuss its limitations. Second,
we detail possible future directions and visions we contemplate for the further
evolution of the field. The article should therefore serve two purposes: giving
the interested reader an overview of current challenges in MRS research and
providing guidance for young researchers by identifying interesting, yet
under-researched, directions in the field
