The ways individuals use words can reflect basic psychological processes, including clues to their thoughts, feelings, perceptions, and personality. This paper seeks to determine whether there is a relationship between Iranian EFL learners' writing styles and their personality and gender.  It focuses on gender and two key dimensions of personality (Neuroticism and Extroversion), which were asse...

Dialogue systems are artefacts that converse with human users in order to achieve some task. Each step of the dialogue requires understanding the user’s input, deciding on what to reply, and generating an output utterance. Although there are many ways to express any given content, most dialogue systems do not take linguistic variation into account in both the understanding and generation phases...

While text-based deception in computer mediated communication has been studied, e.g., Zhou (2005) and Duran et al. (2010), there has been less focus on the differentiation of strategies for deception, especially those which may manifest in modern communication, such as found in social media. In this paper, we extend our previous work on the evaluation of linguistic indicators to strategic decep...

Linguistic markers of personality traits have been studied extensively, but few crosscultural studies exist. In this paper, we evaluate how native speakers of American English and Arabic perceive personality traits and naturalness of English utterances that vary along the dimensions of verbosity, hedging, lexical and syntactic alignment, and formality. The utterances are the turns within dialog...

Psychology research suggests that certain personality traits correlate with linguistic behavior. This correlation can be effectively modeled with statistical natural language processing techniques. Prediction accuracy generally improves with larger data samples, which also allows for more lexical features. Most existing work on personality prediction, however, focuses on small samples and close...

Microblogging services such as Twitter have become increasingly popular in recent years. However, little is known about how personality is manifested and perceived in microblogs. In this study, we measured the Big Five personality traits of 142 participants and collected their tweets over a 1-month period. Extraversion, agreeableness, openness, and neuroticism were associated with specific ling...

Leveraging the findings in Psycholinguistic studies, we now can automatically compute an individual’s personality traits, including Big 5 traits, emotions, and human basic values, from one’s linguistic footprints left on social media. To help users interpret one’s personality traits derived from social media, we are building interactive visual analytic systems with a set of visual representatio...
