The Concept Classification Dictionary is a set of concept classification records (see a figure below).
Each record consists of entry information and concept definition information. The entry information is composed of the concept identifier and the headconcept.
The concept definition information is composed of the concept explication, concept classification information, and concept description information.
The concept classification information describes a list of super-sub relations between concepts.
The super-sub relation is an inclusion relation between concepts.
The concept of a 'school,' for example, has 'organization,' 'building,' and 'function' as its super-concepts, and has 'elementary school,' 'university,' and so forth, as its sub-concepts.
The concept description information describes the semantic relations (e.g. agent, implement, and place) with other concepts.
The other fields, that is the concept identifier, headconcept, and concept explication are explained in the semantic information section of the Word Dictionary.
The Concept Description Dictionary is a set of concept description records.
In this information, the semantic relation between concepts is described with a truth value, and a plausibility value is assigned for each relation set.
