Claustrum Volume Is Reduced in Multiple Sclerosis and Predicts Disability
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective The claustrum is a small, thin structure of predominantly gray matter with broad connectivity and enigmatic function. Little is known regarding the impact of claustrum pathology in multiple sclerosis (MS). Methods This study assessed whether claustrum volume was reduced in MS and whether reductions were associated with specific ...

Early Language Impairment as an Integral Part of the Cognitive Phenotype in Huntington's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Huntington's disease (HD) speech/language disorders have typically been attributed to motor and executive impairment due to striatal dysfunction. In‐depth study of linguistic skills and the role of extrastriatal structures in HD is scarce.

Knowledge structures in a knowledge base
Expert Systems, 2016AbstractRough set theory is a useful tool for dealing with imprecise knowledge. One of the advantages of rough set theory is the fact that an unknown target concept can be approximately characterized by existing knowledge structures in a knowledge base. This paper explores knowledge structures in a knowledge base.

Knowledge bases (KBs) must be able to capture a wide range of situations. One must be able to represent and answer questions regarding indefinite information where it is not clear that there is a unique answer to a question. One must also represent and answer questions about negative information. We discuss a powerful way to represent such information,

Psychological Reports, 2007
This study tested the distinction between knowledge-based choices and gambling decisions. Gambling decisions contain stated probabilities, and success depends on chance only. In knowledge-based decisions, in contrast, the probabilities are usually unknown and the outcomes of a choice depend on a person's ability or knowledge.

Intelligence Based on Knowledge – Knowledge Based on Intelligence
Interdisciplinary Science Reviews, 1987AbstractThe title of this review indicates the fundamental difficulty of defining the difference between intelligence and knowledge. Here some of the basic differences and similarities are discussed, and by analogy with energy, the author postulates the existence of potential and kinetic intelligence. This leads him to the definition of intelligence as

The Knowledge Engineering Review, 2000
This paper surveys the most representative approaches of knowledge-base revision. After a description of the revision characterization according to the AGM paradigm, the paper reviews different revision methods. In each case, the same example is used, as a reference example, to illustrate the different approaches.

Incompleteness in knowledge bases
ACM SIGART Bulletin, 1980The first topic for discussion at the High Level Abstraction Workshop was What should be modelled? that is, what aspects of the world (slice of reality / enterprise) must be dealt with in a high level conceptual model. I would like to address this question from the point of view of incomplete knowledge bases.

One Knowledge Base or Many Knowledge Pools? [PDF]
, 2012 It is increasingly realized that knowledge is the most important resource and that learning is the most important process in the economy. Sometimes this is expressed by coining the current era as characterised by a ‘knowledge based economy'. But this concept might be misleading by indicating that there is one common knowledge base on which economic
