Semantic relevance and semantic disorders.
Semantic features are of different importance in concept representation. The concept elephant may be more easily identified from the feature than from the feature . We propose a new model of semantic memory to measure the relevance of semantic features for a concept and use this model to investigate the controversial issue of category specificity. Category-specific patients h...

متن کاملThe Relevance of Semantic Subtyping
We compare Meyer and Routley’s minimal relevant logic B+ with the recent semanticsbased approach to subtyping introduced by Frisch, Castagna and Benzaken in the definition of a type system with intersection and union. We show that – for the functional core of the system – such notion of subtyping, which is defined in purely set-theoretical terms, coincides with the relevant entailment of the lo...
متن کاملOntology-based Semantic Relevance Measure
Semantic relevance among information resources can play an effective role in information retrieval, and there are several different approaches to measure semantic similarities. However, they are usually limited measuring similarities among structured concepts, and some also considers the similarities between individual resources but they are limited to to textual documents. This paper aims to e...
