In the field of agents, there are a wide variety of them, such as learning agents, planning agents or communicative agents. One of the youngest members in the family are mobile agents, which provide us with the interesting feature of mobility in order to perform their tasks in different machines. In this paper, we will see some of the current uses of mobile agents and we will suggest how we cou...

A comparison of the effects of transactional and transformational leadership in synchronous and a synchronous online teamwork was conducted. In the study, groups of four participants interacted in online text chat and online text forum in problem solving tasks. The groups were leaded by a confederate who acted as a transactional or a transformational leader. Satisfaction in the interactions and...

The problem of classifying text with respect to belonging to a document or a meta-document is formulated and its application areas are proposed. An algorithm is proposed for document classification tasks where counts of words is insufficient do differentiate between such abstract classes of text as metalanguage and object-level. We extend the parse tree kernel method from the level of individua...

Dogs are more skillful than great apes at a number of tasks in which they must read human communicative signals indicating the location of hidden food. In this study, we found that wolves who were raised by humans do not show these same skills, whereas domestic dog puppies only a few weeks old, even those that have had little human contact, do show these skills. These findings suggest that duri...

The purpose of this paper is to present a method for automatic classification of dialogue utterances and the results of applying that method to a corpus. Superficial features of a set of training utterances (which we will call cues) are taken as the basis for finding relevant utterance classes and for extracting rules for assigning these classes to new utterances. Each cue is assumed to partial...

This paper investigates phonetic and prosodic features of polite versus informal speech. Two different communicative tasks were performed by speakers of two unrelated and culturally distant languages, Korean and German. We found that the polite speech of Korean speakers can be characterized by an increase of filled pauses and extralinguistic markers, a higher degree of breathiness, as well as l...

Young children with developmental (cognitive) delays experience unusual difficulties in establishing relationships with their peers and developing friendships. A conceptual model of children’s peer-related social competence is presented by identifying information-processing and emotional regulation processes governing the production of social strategies occurring during social tasks. Contempora...

This work explores what people do to inform their surroundings about who is the main addressee of their communicative acts in smart environments. A corpus of naive users, solving daily tasks in a smart home, which is additionally inhabited by a robot, is investigated. Evidence drawn from the corpus is used to create a first model for addressee recognition in smart environments. Finally, the per...

Human communicative competence is based on the ability to process a specific class of mental states, namely, communicative intention. The present fMRI study aims to analyze whether intention processing in communication is affected by the expressive means through which a communicative intention is conveyed, that is, the linguistic or extralinguistic gestural means. Combined factorial and conjunc...

Humans are biased toward social interaction. Behaviorally, this bias is evident in the rapid effects that self-relevant communicative signals have on attention and perceptual systems. The processing of communicative cues recruits a wide network of brain regions, including mentalizing systems. Relatively less work, however, has examined the timing of the processing of self-relevant communicative...
