This paper investigates the factors that affect users’ communication satisfaction within a virtual community, in particular, an online chat room. A research model consisting of 3 aspects—psychological, technological and environmental—is developed to examine effects of anonymity, media richness and activeness of chat room on social presence, privacy concern, and further communication satisfactio...

The purpose of this study is to explore the advergame personality (AP) dimensions and to explicate the underlying relationships of the AP dimensions with company attributes, product categories, and consumers' behavioral intentions. A series of surveys with convenience samples indicates that consumers ascribe personality characteristics to advergames and that the perceived AP is five-dimensional...

Service Orientation has been an extensively used approach to model the services Collaborative Networks' (CN) members are willing to provide to customers. The evolution of this paradigm has followed an improvement path since its early forms. Nevertheless bottlenecks still exist, namely in what concerns: 1) a gap between the business and the information and communication technology perspectives; ...

Recently, there has been a growing interest in the Agent-oriented paradigm to cope with the needs imposed by nowadays complex and networked systems. Developing Multi-Agent Systems (MAS) calls for addressing aspects such as interaction, autonomy, collaboration and pro-activeness. One way to cope with these needs is to have agency properties as well as intentionality in the center of the software...

Household robots need to communicate with human beings in a friendly fashion. To achieve better understanding of displayed information, an importance and a certainty of the information should be communicated together with the main information. The proposed intent expression system aims to convey this additional information using an eye robot. The eye motions are represented as states in a pleas...

We present PLANet: an active network architecture and implementation. In addition to a standard suite of Internet-like services, PLANet has two key programmability features: 1. all packets contain programs 2. router functionality may be extended dynamically Packet programs are written in our special purpose programming language PLAN, the Packet Language for Active Networks, while dynamic router...

Question Answering platforms are becoming an important repository of crowd-generated knowledge. In these systems a relatively small subset of users is responsible for the majority of the contributions, and ultimately, for the success of the Q/A system itself. However, due to built-in incentivization mechanisms, standard expert identification methods often misclassify very active users for knowl...

We present a new methodology for controlling the space-time behavior of VLSI and FPGA-based processor arrays. The main idea is to generate simple local control elements which take control over the activeness of each attached processor element. Each control element thereby propagates a “start” and a “stop execution” signal to its neighbors. We show that our control mechanism is much more efficie...

Distributed Artificial Intelligence techniques have evolved toward multi-agent systems (MASs) where agents solve specific problems. Bargaining is a challenging area well-explored in both MAS and economics. To make agents more human-like and to increase their flexibility to reach an agreement, the authors investigated the role of personality behaviors of participants in a multi-criteria bilatera...
