Abstract

Scientific documents are more or less important in relation to give subjects and this importance can be measured. An empirical investigation into philosophical information was carried out using a weighting algorithm developed by N. Henrichs which results in a distribution by weighting of documents on an average philosophical subject. With the aid of statistical methods a threshold value can be obtained that separates the important and unimportant documents on a subject. The knowledge of theis threshold value is important for various practical and theoretic questions: providing new possibilities for research strategy in information retrieval; evaluation of the 'titleworthiness' of subjects by comparison of document titles and themes for which the document at hand is important; and making available data on thematic trends for scientific results
