Abstract

The argumetns of Pt.1-3 are applied to two main issues: (a) the separation of the physical and mental components of information phenomena, illustrated by a discussion of the aging of periodicals, (b) the role of the Bradford Law and ranking techniques as a means of exploiting all the information inherent in the raw data. The paper concludes with a brief discussion of a propsed new kind of data-base in which objective information is structured into objective knowledge

Abstract

The metrical characteristics of information space are compared with those of physical space. An abstract model is used to show that information space is like that of landscapes and skyscapes. As individuals we learn very early to correct the distortions that subjective appearances impose on us but traces of this process are shown by cosmological history. These arguments are supported by other evidence indicating that information quantities should be measured logarithmically

Abstract

It is argued that in information science we have to distinguish physical, objective, or document space from perspective, subjective, or information space. These two spaces are like maps and landscapes: each is a systematic distortion of the other. However, transformations can be easily made once the two spaces are distinguished. If the transformations are omitted we only get unhelpful physical solutions to information problems

Abstract

It is first argued that a niche for information science, unclaimed by any other discipline, can be found by admitting the near-autonomy of Popper's World III - the world of objective knowledge. The task of information science can then be defined as the exploration of this world of objective knowledge which is an extension of, but is distinct from, the world of documentation and librarianship. The Popperian ontology then has to be extended to admit the concept of information and its relations to subjective and objective knowledge. The spaces of Popper's three worlds are then considered. It is argued that cognitive and physical spaces are not identical and that this lack of identity creates problems for the proper quantification of information phenomena

Abstract

An outline history describes how man has extended the process of objectivization from everyday practicalities to modern science. Modern techniques of quantification awaited the adoption of the Hindu-Arab numerals and the creation of a calculus for their use. It is argued that the use of these numerals has provided analytical instruments which, though ideally adapted to the exploration and exploitation of the physical world, fail to capture important aspects of the individuality of response within groups which humans display in their social behaviour. New quantitative techniques more sensitive to these aspects are therefore needed in the social sciences. A numerical example is used to illustrate how frequency-rank statistics make fuller use of empirical information in the social sciences than conventional statistics which, by using classes, discards information related to individuality
