recent studies in affective computing are focused on sensing human cognitive context using biosignals. in this study, electrooculography (eog) was utilized to investigate memory recall accessibility via eye movement patterns. 12 subjects were participated in our experiment wherein pictures from four categories were presented. each category contained nine pictures of which three were presented t...

The complexity and impact of many real world decision making problems lead to the necessity of considering multiple points of view, building group decision making problems in which a group of experts provide their preferences to achieve a solution. In such complex problems uncertainty is often present and although the use of linguistic information has provided successful results in managing it,...

An increase of asynchronous online discussions in website provides much opportunity for L2 learners from different global communities to be exposed to the target language at their own pace and time. However, no research looking at the essentials of social presence and cognitive presence in creating a supportive learning environment in such a context has been done. This study investigated the pa...

Research on context-aware communications recently led to the introduction of features and algorithms relying on the presence and rich, accurate context information, requiring however the introduction of cross-layer information exchanges. Cognitive radio (CR), in particular, is expected to benefit from context awareness, as the cognitive engine (CE) relies on the availability of multiple informa...

ADAPT (Adaptive Dynamics and Active Perception for Thought) is a cognitive architecture specifically designed for robotics. The ADAPT architecture is in the initial state of development. ADAPT manipulates a hierarchy of perceptual and planning schemas that include explicit temporal information and that can be executed in parallel. Perception is active, which means that all perceptual processing...

Object identification via a perceptual-demonstrative mode of presentation has been studied in cognitive science as a particularly direct and context-dependent means of identifying objects. Several recent works in cognitive science have attempted to clarify the relation between attention, demonstrative identification and context exploration. Assuming a distinction between ‘(language-based) demon...

Four different kinds of grammars that can define crossing dependencies in human language are compared here: (i) context sensitive rewrite grammars with rules that depend on context, (ii) matching grammars with constraints that filter the generative structure of the language, (iii) copying grammars which can copy structures of unbounded size, and (iv) generating grammars in which crossing depend...
