Early warning of risks of copyright infringement in digital library based on extension theory.

Purpose – The purpose of this study is to evaluate the potential risks of copyright infringement in digital library based on the extension theory. Design/methodology/approach – At first, the analytic hierarchy process (AHP) is used to determine the weights of the existing indicator system for early warning. Second, a model is built to evaluate the potential risks of copyright infringement based on the extension theory in digital library. Finally, a real-world application is presented to show the effectiveness and usefulness of this approach. Findings – The main findings of this paper are as follows: the early warning extension theory model is effective in distinguishing the degree of the potential risks of copyright infringement in digital library; the ranges of the value and the values of the indicators can directly affect the results while using this approach, so the accuracy of these two aspects is a crucial question. Social implications – The social impact is that copyright infringement risks of digital library is reduced; the lawsuit rate and economic loss due to copyright infringement are thereby decreased as well. Originality/value – This paper introduces the evaluation of the potential risks of copyright infringement based on the extension theory in digital library. The results provide support for the decision-makers in handling the potential risks of copyright infringement in digital library. [ABSTRACT FROM AUTHOR]
