- Abstract
- Until very recently, classification theory was held to be nothing but an expressed or unconscious knowledge framed in intuitively given reasons for the subdivision and arrangement of any universe. Today, after clarification of the elements of classification systems as well as the basis of concept relationshios it is possible to apply a number of principles in the evaluation of existing systems as well as in the construction of new ones and by this achieving relatively predictable and repeatable results

- Abstract
- A concept is regarded as the common element of both classification systems and thesauri. Reality and knowledge are not represented by words or terms but by the meanings "behind" these tokens. A concept of, say, an object, a property of an object, a process, etc. is derived from verbal statements on these as subjects and may therefore be defined as the whole of true and possible predicates that can be collected on a given subject. It is from these predicates that the characteristics of the corresponding concepts can be derived. Common characteristics in different concepts lead to relationsbetween concepts, which relations in turn are factors for the formation of concept systems. Different kinds of relationships as well as different kinds of concepts are distinguished. It is pointed out that an orderly supply of the elements for propositions (informative statements) on new knowledge requires the construction and availability of such concept systems
