One is the comparison between the attributes ‘abstract’ and ‘keyword’. While both ‘abstract’ and ‘keyword’ are provided by the authors for represent...

Semantic cognition is underpinned by regions involved in representing conceptual knowledge and executive control areas that provide regulation of this information according to current task requirements. Using distortion-corrected fMRI, we investigated the contributions of these two systems to abstract and concrete word comprehension. We contrasted semantic decisions made either with coherent co...

The Hierarchical Temporal Memory (HTM) approach to perception processing, pursued by prior authors including Jeff Hawkins and Itamar Arel, is expanded to encompass more abstract semantic forms of HTM, and to include separate, coupled hierarchies for perception, motor control and goal management. No experimental evidence or detailed calculations are presented; this is merely a conceptual paper d...

Patients with semantic dementia (SD) have a striking impairment in semantic memory, but the basis for this deficit is unclear. We examined semantic memory for concrete and abstract verbs with a two-alternative, forced-choice measure of lexical semantic associative knowledge. Patients with SD had significantly greater difficulty with concrete verbs (z = -3.33) than with abstract verbs (z = -2.05...

We propose a method for semantic structure analysis of noun phrases using Abstract Meaning Representation (AMR). AMR is a graph representation for the meaning of a sentence, in which noun phrases (NPs) are manually annotated with internal structure and semantic relations. We extract NPs from the AMR corpus and construct a data set of NP semantic structures. We also propose a transition-based al...

Abstract In this paper we report on the analyses of alternative approaches to semantic role annotation (FrameNet (FrameNet, 2005), PropBank (Palmer et al., 2005) and VerbNet (Kipper, 2006)) with respect to their models of description; granularity of semantic role sets; definitions of semantic roles concepts; and consistency and reliability of annotations, and we propose a methodological basis f...

Abstract. Semantic annotation of digital documents is typically done at metadata level. However, for fine-grained access semantic enrichment of text elements or passages is needed. Automatic annotation is not of sufficient quality to enable focused search and retrieval: either too many or too few terms are semantically annotated. User-defined semantic enrichment allows for a more targeted appro...

The neuropsychological investigation of semantic memory has mainly focused on concrete concepts, while abstract concepts have been relatively neglected. We describe a new battery for assessing abstract concepts in brain-damaged patients. The battery includes three different tests: an association task, a multiplechoice naming-to-description task and a sentence completion task. The three tasks ar...

This paper presents a static semantic analysis for CASL, the Common Algebraic Speciication Language. Abstract syntax trees are generated including subsorts and overloaded functions and predicates. The static semantic analysis, through the implementation of an overload resolution algorithm, checks and qualiies these abstract syntax trees. The result is a fully qualiied CASL abstract syntax tree ...
