Task 1.b - Abstract/Concrete Nouns Discrimination
Introduction
The contrast between abstract and concrete words plays a central role in human cognition. Actually, behavioural and neuropsychological evidence suggests that abstract and concrete concepts might be represented, retrieved and processed differently in the human brain.
Since semantic classifications of abstract nouns have a higher degree of arbitariness than the ones for concrete nouns, we have not defined any a priori "ontology" of classes for the abstract domain. Instead, we will test computational models for their ability to discriminate between abstract and concrete nouns.
The data set consists of 40 nouns extracted from the MRC Psycholinguistic Database, with rates by human subjects on the concreteness scale.
Task Operationalization
The nouns have been classified into three classes, dependdng on their concreteness value in MRC:
