This paper introduces a novel approach for document re-ranking in information retrieval based on topic-comment structure of texts. While most information retrieval models make the assumption that relevant documents are about the query and that aboutness can be captured considering bags of words only, we rather consider a more sophisticated analysis of discourse to capture document relevance by distinguishing...
Framing or priming a situation can subtly influence how a person reacts to or thinks about the situation. In this paper, we describe a recent study and some preliminary results in which the framing of a robot is manipulated such that it is presented as a social agent or as a machine-like entity. We ask whether framing the robot in these ways influences young children's social behavior during an interaction...
Written language as a symbolic medium of expression plays an important role in communications. In particular, written words communicated online can provide indications of an actor's behavioral intent. This paper describes an ongoing investigation into the interconnectivity between words and actions for a deceptive insider on group dynamics in virtual team collaboration. An experiment using an online...
As the use of computer-mediated communications has increased, the potential risk of online deception has grown -- as has the importance of better understanding human behavior online to mitigate these risks. Previous research has demonstrated that linguistic features provide crucial cues to detect deception, and that reasonable accuracy in detection of deception can be achieved by applying certain...
The aim of this study was to investigate the effects of using a smartphone application in a Communicative Language Teaching context. Specifically, a web-based application called Let's Talk was designed to facilitate an Information Gap activity in an English language class. Participants were assigned to an experiment group using Let's Talk or a control group using textbooks to practice English conversation...
Explicit customer review ratings mark future business success. One important and well-studied aspect of customer satisfaction is a review's affective — positive or negative — valence. More recently, tools from natural language processing (NLP) applied to reviews show less obvious linguistic differences in review texts dependent on reviewer rating. Consistent with this is previous work using Linguistic...

The task of achieving competent artificial natural language systems is enormous. Advances in hardware and the structural analysis of verbalizations have outpaced theories of language and cognition. Functional contextualism, a behavioral approach in psychology, has seen the rise of relational frame theory, which offers an alternative conceptualization of language and cognition. This theory is based...
Given the very ambiguous and imprecise nature of sentiments and of their expressions, this survey focuses on approaches making use of components of graduality in the task of automatic sentiments analysis. To that aim, we review methods taking account of intrinsic psychological models components of graduality as well as extrinsic components issued from computational intelligence approaches. In particular,...
This paper reports the results of a survey regarding motivation for learning English as a foreign language. The subjects are 64 Japanese university students majoring in computer science and engineering. Research on motivation for learning second/foreign languages, first initiated in the 1970s, has been attracting attention especially since the 1990s. The results indicate that these students, whose...
The paper discusses several issues concerning the lexicon within a psycholinguistic pragmatic model of language which takes into account both use and competence. Besides semantic information entailed in the word meaning, the lexicon also includes the semantic relations. Therefore, the logical line of research should combine the pragmatic perspective with a model of language competence and language...
