It is our pleasure to welcome all of you to Budapest on behalf of the organizers of the 4th IEEE International Conference on Cognitive Infocommunications.
A survey of software and technology architecture about systems dedicated for analysis of Online Social Networks (OSN) will be presented. Based on the comparison and own experiments a novel approach proposed. The steps of experiments are described. The proposed solution is applied for Twitter and Facebook.
Human activities are embedded in the space. People need to know where they are (positioning) and how they can arrive to their destination (wayfinding). Among several navigation aids (e.g., maps and satellite navigation systems), they may use their spatial knowledge (i.e., cognitive map) for this aim, especially in familiar spaces. This paper presents an agent-based modelling of how spatial knowledge...
Using a sentiment lexicon for German translated into English, Italian, Spanish and Swedish, Tumblr URL names for blog archives are inspected with regard to the category of the content. Across the five languages, where the content would be of concern to anyone who would be inclined to filter offensive content, the URLs are constructed with negative sentiment expressions more often than positive sentiment...
This paper presents an implementation of a reduced Ethernet MAC. The reduced MAC is simple and not resource wasteful. Therefore it is suitable to every project which includes network communication. It is especially useful to low performance FPGAs. In practice, the FPGA boards are well applicable to implement network protocols because the implemented protocols will work in parallel. The main topics...
Based on the incremental nature of knowledge learning, in this study a growing self-organizing neural network approach for modeling the acquisition process of semantic features is proposed. The Growing Self-Organizing Map (GSOM) algorithm is extended and applied to the problem of language acquisition. Based on that algorithm, experiments are conducted using Standard German children's books corpus...
This paper presents and demonstrates a Brain Computer Interface (BCI) system for EEG control of an industrial robot manipulator. An Emotiv EPOC device is applied for the recording of the brain activity. The developed BCI system registers the brain rhythmic activity through electrodes situated on the scalp. The recognition of the brain activity is associated with facial expressions and cognitive actions...
We consider the problem of distributing media files for streaming on a distributed storage network, where servers have heterogeneous capacities and bandwidths. Regarding networking the servers' bandwidths are the bottlenecks for streaming. We present an algorithm that computes an assignment of n files to m servers for distributing media files such that the streaming speed requirements and capacity...
Cognitive infocommunications (CogInfoCom) study the connections between infocommunications and cognitive experiences. This paper matches with the purpose of the Conference because it explores Enactive knowledge and its relations with Interaction Design of Multimodal Interfaces. Enactive knowledge is what it is built through the action and is built on motor skills as manipulating an object, riding...
We present an emotion ontology for describing and reasoning on emotion context in order to improve emotion detection based on bodily expression. We incorporate context into the two-factor theory of emotion (bodily reaction plus cognitive input) and demonstrate the importance of context in the emotion experience. In attempting to determine emotion felt by another person, the bodily expresson of their...
This research aims at finding how suspects in police interrogations express their interpersonal stance -in terms of T.Leary's interpersonal circumplex- through body postures and facial expressions and how this can be simulated by virtual humans. Therefore, four types of stances were acted by eight actors. To see if the resulted postures are valid, short recordings were shown online in a survey to...
We propose a method of generating different scale-free networks, which has several input parameters in order to adjust the structure, so that they can serve as a basis for computer simulation of real-world phenomena. The topological structure of these networks was studied to determine what kind of networks can be produced and how can we give the appropriate values of parameters to get a desired structure.
This document reports a public exhibition organized during the French National Days of Archaeology, that is the result of an interdisciplinary collaboration between archaeologists and computer scientists, centered on the immersive virtual reality platform Immersia, a node of the European Visionair project. This public exhibition had three main goals: (i) presentating our interdisciplinary collaboration,...
In this paper we present a mathematical model of a quadrocopter, together with a complete supervisor solution for path planning to cover a designated area with a quadrocopter type UAV. The supervisor is also able to optimize and recalibrate its route in the case of unexpected events during flight, such as sudden changes in wind, or someone physically altering its position in the path. Simulations...
Temporal Discrete Cosine Transform (TDCT) features have shown good performance in the speaker verification task, and in this paper we utilize them in speech emotion recognition. Tests were conducted on a Serbian emotional speech database, using Neural Networks (NN) as a classifier and Mel-Frequency Cepstral Coefficients (MFFC) as a reference feature set. Even though MFCC is one of the most employed...
We present two components of a computational system for emotion detection. PEMs (Personalized Emotion Maps) store links between bodily expressions and emotion values, and are individually calibrated to capture each person's emotion profile. They are an implementation based on aspects of Scherer's theoretical complex system model of emotion [1], [2]. We also present a regression algorithm that determines...
