G-layer of RGPS requirement meta-model is used to refine the general business goals acquired on the basis of the Role layer. A business goal is a high-level and general statement when first proposed. Whether it can be achieved or not depends on the correctness of goal decomposition. Towards these problems, a decomposition model is proposed in this paper. Particularly, with the development of semantic...
This paper presents an overview of the emerging field of emotion detection from text and describes the current generation of detection methods that are usually divided into the following three main categories: keyword-based, learning-based, and hybrid recommendation approaches. Limitations of current detection methods are examined, and possible solutions are suggested to improve emotion detection...
Nonlinear analysis of electroencephalogram (EEG) signals provides a means for studying the dynamical changes in cortical networks related to brain electrical activity. In this study, the correlation dimension (D/sub 2/) and point correlation dimension (PD/sub 2/) were used to investigate the quantitative complexity of EEG during cognitive processes. EEGs were recorded in 30 normal subjects under seven...
Cognition process is directly related to the brain functionality and is a dynamically changing system. Nonlinear analysis of EEG signals has been used as a means for studying the dynamical changes in cortical networks. In the course of cognition process, the activity complexity of the neuronal units is continually shifting. This phenomenon can be viewed with the topographic map and nonlinear EEG measures...
There has been relatively little study of the longitudinal course of cognitive functioning before the onset of schizophrenia. We report scores from standardized academic examinations at ages 12 and 16 years of 30 male patients with a first episode of schizophrenia (FES) and a normal control group balanced for gender, age, parental socio-economic class and academic scores at age 12. The FES group had...
