Document Summary

> network: an interrelated set of concepts or interrelated body of knowledge. > node: a point or location in the semantic space. > property statement: x has the property or feature y . > isa statement: x is a y . * advantage: it limits the amount of information in memory (cognitive economy) Spreading activation model: both concepts and properties are represented by nodes, the organization is non-hierarchical. Every node is connected to every node: only one node may be activated at one time, however, once activated, nodes send activation to their neighbours in parallel, the strength of association between nodes may be represented by distance. Sentence verification task: premises are presented with a sentence, which either makes it true or false. * assumes that concepts are defined by lists of semantic features. A concept"s features are listed in terms of definingness (how essential is the feature to a concept)
