The knowledge representation field is gaining momentum with the advent of the Semantic Web activity within the W3C. This working group, thanks to previous researches, has proposed the Ontology Web Language to enhance the expressivity of web pages and to allow semantic inferences. This paper argues that knowledge representation technologies should be core components of multi-agent platforms. In ...

Starting from the standard call-by-need reduction for the λ-calculus that is common to Ariola, Felleisen, Maraist, Odersky, and Wadler, we inter-derive a series of hygienic semantic artifacts: a reduction-free storeless abstract machine, a continuation-passing evaluation function, and what appears to be the first heapless natural semantics for callby-need evaluation. Furthermore we observe that...

Semantic priming for category coordinates (e.g. CAT–DOG; AEROPLANE–TRAIN) and for pairs of words related through function (e.g. BROOM–FLOOR; SHAMPOO–HAIR) was assessed in children with good and poor reading comprehension, matched for decoding skill. Lexical association strength was also manipulated by comparing pairs of words that were highly associated with pairs that shared low association st...

Modeling 3D shapes is a specialized skill not affordable to most novice artists due to its complexity and tediousness. At the same time, databases of complex models ready for use are becoming widespread, and can help the modeling task in a process called example-based modeling. We introduce such an example-based mesh modeling approach which, contrary to prior work, allows for the replacement of...

background and purpose: clinical competence has four essential components: knowledge , physical exam , problem solving and communication skill .the communication skill isn’t an optional extra in medical training but it is a core clinical skill. this study is performed in order to determine whether communication skill training for internal medicine and infectious disease residents improves their...

Children with specific reading comprehension difficulties were compared with control children on tests of language skill. The two groups performed at a similar level on tests requiring predominantly phonological skills, but the poor comprehenders performed less well on tests tapping semantic ability. Although the two groups were matched for decoding ability (as assessed by nonword reading), the...

Background: Individuals with autism exhibit typical recognition memory performance, but they show a reduced use of context and relational processing in more complex memory tasks. It is unclear whether the same is true for autistic individuals with exceptional memory skill for whom superior rote memory skill has been assumed. Objective: In this study, we investigated recognition memory for high ...

BACKGROUND Surgical tasks are performed in a sequence of steps, and technical skill evaluation includes assessing task flow efficiency. Our objective was to describe differences in task flow for expert and novice surgeons for a basic surgical task. METHODS We used a hierarchical semantic vocabulary to decompose and annotate maneuvers and gestures for 135 instances of a surgeon's knot performe...

The article provides an insight into a problem of lexical semantic change. A short historical outline of the development of semantic studies is given. The authors analyze some of the most important stages in the history of the formation of this field. The existing approaches to dealing with form and meaning, namely semasiological and onomasiological ones are discussed. The authors consider the ...
