Automatic deception detection is a crucial task that has many applications both in direct physical and in computer-mediated human communication. Our focus is on automatic deception detection in text across cultures. In this context, we view culture through the prism of the individualism/collectivism dimension, and we approximate culture by using country as a proxy. Having as a starting point recent conclusions drawn from the social psychology discipline, we explore if differences in the usage of specific linguistic features of deception across cultures can be confirmed and attributed to cultural norms in respect to the individualism/collectivism divide. In addition, we investigate if a universal feature set for cross-cultural text deception detection tasks exists. We evaluate the predictive power of different feature sets and approaches. We create culture/language-aware classifiers by experimenting with a wide range of n-gram features from several levels of linguistic analysis, namely phonology, morphology and syntax, other linguistic cues like word and phoneme counts, pronouns use, etc., and token embeddings. We conducted our experiments over eleven data sets from five languages (English, Dutch, Russian, Spanish, and Romanian), from six countries (United States of America, Belgium, India, Russia, Mexico, and Romania), and we applied two classification methods, namely logistic regression and fine-tuned BERT models. The results showed that the undertaken task is fairly complex and demanding. Furthermore, there are indications that some linguistic cues of deception have cultural origins and are consistent in the context of diverse domains and data set settings for the same language. This is more evident for the usage of pronouns and the expression of sentiment in deceptive language. The results of this work show that the automatic deception detection across cultures and languages cannot be handled in unified manners and that such approaches should be augmented with knowledge about cultural differences and the domains of interest.
Most existing Natural Language Database Interfaces (NLDB) were
designed to be used with
database systems that provide very limited facilities for manipulating
and they do not support adequately temporal linguistic mechanisms (verb
adverbials, temporal subordinate clauses, etc.). The database community
increasingly interested in temporal database systems, which are intended
to store and manipulate
in a principled manner information not only about the present, but also
about the past and
future. When interfacing to temporal databases, supporting temporal linguistic
We present a framework for constructing Natural Language Interfaces
Databases (NLTDB), which draws on research in tense and aspect theories,
and temporal databases. The framework consists of a temporal intermediate
language, called TOP, an HPSG grammar that maps a wide range of questions
temporal mechanisms to appropriate TOP expressions, and a provably correct
translating from TOP to TSQL2, TSQL2 being a recently proposed temporal
extension of the
SQL database language. This framework was employed to implement a prototype
