Information Theory as a Measure of Information Content

Belzer, Jack

Journal of the American Society for Information Science, 24, 4, 300-304, Jul-Aug 73

Entropies of surrogates such as citations, abstracts, first paragraphs, last paragraphs, and first and last paragraphs are measures of how well each class of surrogates predicts relevancy of documents. They are measures of meaningful information in the text of surrogates. Such measures of information are important to information system designers. (4 references) (Author)
