Use of the input–output matrix to determine the hierarchy of information on the Internet

Abstract

The author examines the Internet network as a global economy in which the only output is information. It is assumed that there is a certain hierarchy of keywords in the net space. Important keywords create large information graphs, which attract smaller graphs consisting of less important data. Information graphs are linked to each other like branches of production in classical economics. Thus, due to the huge amount of information on the net, it is difficult to measure its quality, or whether it is true or false. A non-standard method of measuring information is proposed, as well as analysis of the weights between each of the keywords. Search results from Internet search engines were used. The input–output matrix was used to analyze the amount of information, as well as dependencies which occur between individual keywords.Internet network, production of information, vector, graph of information, input–output model, keyword analysis
