The value of information in the information system in its quality assessment

Abstract

The purpose of the article is to determine to what extent and how to evaluate the value of information available in the information system when assessing its quality. Such an evaluation, especially for systems operating on the Internet, is absolutely necessary because of the constant and rapid growth of the information resources available there, bearing the unnecessary economic costs of their poor quality and related to that negative social phenomena. The quality of information is a multidimensional category and requires evaluation of great number of different attributes. Are there among conceptual models for evaluating the quality of information also such that require evaluating the value of information? What quality attributes are associated with the value of information? What are the concepts and how one can evaluate the value of information in an information system in practice? These are just some of the questions that the author is trying to answer in this article. As a research method, comparative analysis of the best literature known models of information quality assessment in the information system was used. The results of the considerations are conclusions regarding the practice of evaluating the quality of information. They concern, firstly, the emplacement of the criterion of information value in the dimension structure of information quality. Secondly, they relate to the possible methods and techniques for evaluating the value of information that is used to assess the quality of information in the information system. It was concluded that the proposed method of measuring the value of information in analysed models is the method of a survey.
