These initiatives may also expand externally over time and include partners and customers. The connectionist computer uses a special representation, termed value unit encoding, that represents small subsets of parameters in a way that allows parallel access to many different parameter values. (Eds. It was originally defined by Polanyi (1958). The second part proposes a representation based on sparse information matrices together with some properties that motivate this approach. In clinical practice, a mixture of several varieties of anomia is frequent, but differentiation can often be made, particularly when related clinical signs are taken into account. Neither patient showed impairment in any other area of language performance. Introduction: The first clinical and experimental studies dealing with hemispheric asymmetries in comprehension, experience, and expression of emotions had been conducted in patients with focal brain lesions or in normal subjects investigated with special experimental procedures. The distinction between ‘animals’ and ‘plant life’ within the ‘living’ categories was confirmed by the analysis of their prevalent sources of knowledge and by a cluster analysis, which allowed to distinguish fruits and vegetables from animals. However, if semantic knowledge about objects contributes to visual working memory capacity, then it follows that age-related increases in semantic knowledge may also contribute to improvements in visual working memory capacity over development. Introduction Theories about knowledge organization in the human brain propose that concepts may be described according either to perceptual processes ortosemanticrepresentations.Speci fically,the modality-specificitytheory In contrast, collective knowledge initiatives in an organization consist of creating and sharing knowledge for improving business and increasing productivity. In aphasia output, one of two distinctly different naming problems may be apparent. An advantage for artefacts is typically associated with an aetiology of Herpes simplex virus encephalitis (which predominantly affects temporolimbic structures) whilst the opposite pattern more often follows damage to frontoparietal regions, ... Several clinical observations of aphasics support this assumption. Access scientific knowledge from anywhere. The resulting knowledge base is a major step beyond WordNet: in quality by adding knowledge about individuals like persons, organizations, products, etc. It plays a central role in enabling the processing and sharing of knowledge within an accepted domain. The problem of producing words appears to be universal in aphasia, but word-finding problems also occur in normal individuals and in many types of cerebral dysfunction. Tentatively, Case 2 is described as being more morphologically impaired but less syntactically impaired than Case 1, while neither has damage to a central language processor. Linguistic data is also presented in support of the hypothesis that semantics knowledge is organized into domains. The authors theorize that these symptoms are mainly correlated with the amnestic syndrome, which is constantly reported in human Kluver-Bucy syndrome. It was Pick's opinion that this symptom, which he called autotopographia or autotopagnosia, could not be accounted for by aphasia, apraxia, or general dementia, and that it reflected the impairment of a discrete ability, the body image (Vorstellungsbild des Körpers). This interesting pattern of preserved semantic information and disrupted phonological processing is unusual in dementia and contrasts with the severe dysnomia of patients with surface dyslexia who are able to read by the indirect, assembly-of-phonology route and show better reading of nonwords than irregular words. In this paper, we present He was mainly influenced by the ideas of Reiff and Scheers, who in 1959 made the distinction between two primary forms of memory. The influence of age was checked by comparing results obtained on our group of elderly subjects with those obtained in a previous study, conducted with the same methodology on a sample of young students, whereas the influence of stimulus modality was assessed by presenting the stimuli in the verbal modality to 50 subjects and in the pictorial modality to 50 other subjects. His speech was slow and dysarthric, consisting of short disconnected phrases with some omission of lexical verbs. a CiteSeer-like, Language is the most evolved and complex of cognitive functions. In Section II, related work is discussed. However, an update of the representation itself needs only constant time, making it highly attractive for building a SLAM algorithm. An ontology provides an agreed understanding of an organization domain knowledge that rests on a common vocabulary. Semantic knowledge is organized such that it affords meaningful and adaptive inferences (e.g., apples and oranges are fruit and therefore can play similar functional roles). Connectionist models are used as examples to illustrate neural representation and computation in the pronouncing of English text, and in the extracting of shape parameters from shaded images. In one, the patient appears to have a problem saying the word while in the second he appears to have a problem knowing the word desired. Tacit Knowledge: This is knowledge acquired through personal experience that is difficult to express. This computer can be thought of as computing hierarchies of sensorimotor invariants. Rather general knowledge also counts in the same. In more recent times, our knowledge of these hemispheric asymmetries has been increased by new lines of research which have investigated: (a) asymmetries in emotional behaviors in animals; (b) neuroanatomical asymmetries in structures playing a critical role in various aspects of emotions, and (c) behavioral and emotional disorders in patients with degenerative brain diseases, temporal lobe epilepsy, and abnormal kinds of emotion regulations On the contrary, according to the second model, proposed by Allport (1985) and Jackendoff (1987) and developed byDamasio (1989Damasio ( , 1990), We constructed a test battery in which subjects were requested to recognize the same persons (well-known at the national level) through their faces and voices, evaluating familiarity and identifica, We organize a Special Issue in the journal "Brain Sciences" on "Emotions and the Right Hemisphere". A complete Enterprise 'Semantic' Knowledge Graph. Semantic Organizational Knowledge (SOK): This concept refers to technologies of the Semantic Web and Linked Data applied to the principles and procedures of organizational knowledge. The popular view of this type of knowledge is a form of knowledge encoded in organizational practices, procedures and routines. They had suggested the models of a different hemispheric specialization and of a general right hemisphere dominance for emotions. Verb production was far superior to noun production in single word naming. One of the deepest mysteries of the function of cortex is that neural processing times are only about one hundred times as fast as the fastest response times for complex behavior. Explicit knowledge is intuitive, based on experience, intractable and refers to knowledge known as “know-how”. Our first aim consisted in rating the influence that different sources of knowledge could have in the representation of animals, plant life and artifact categories, rather than in those of living and non-living beings, as many previous studies on this subject have made. These findings indicate that the difference between the (verbal) format of the semantic knowledge supported by the left hemisphere and the (sensory-motor) format of conceptual representations supported by the right hemisphere is not qualitative, as suggested by the Paivio (e.g., [13,14]) "dual code" theory, but quantitative as proposed by the sensory-motor account of conceptual knowledge (e.g., [12, ... One idea is that representations of different knowledge types are located in separate regions of the brain, and that the location of brain damage is therefore critical in determining which domain of knowledge is prefer- entially disrupted. To derive an estimated map from the representation a sparse linear equation system has to be solved. information to improve the organization, analysis and evaluation of scientific digital libraries. Case 2 had an unusual transient aphasia of acute onset without hemiplegia; speech rate, articulation, and sentence length and complexity appeared normal. Some technologies have been fully studied and utilized upon this meaningful From an early age, children play sorting and matching games. Feature Comparison Model 3. According to the “embodied cognition” theory and to the “sensory-motor model of semantic knowledge”: (a) concepts are represented in the brain in the same format in which they have been constructed by the sensory-motor system and (b) various conceptual categories differ for the weight that different kinds of information play in their representation. SDP relaxations are computationally expensive and hard to exploit in a branch-and-bound framework, where one needs to solve convex relaxations repeatedly. She was remarkable because her relatively preserved object naming and semantic categorization abilities contrasted with severe deficits in speech fluency, oral reading, inability to execute spoken and written commands, and severely impaired auditory-verbal short-term memory. received increasing research interests in recent years.
