Concept evolution analysis based on the Dissipative Structure of Concept Semantic Space

In the domain of text semantic processing, concept semantic evolution is a common phenomenon involved in the lasting process of a concept's formation and development at different stages, which leads concept evolution analysis to be difficult in identifying concept evolution states. To solve the problem, the paper proposes a method of concept evolution analysis based on the Dissipative Structure of Concept Semantic Space (CSS). First, a CSS is constructed as surroundings where a concept forms and its semantic evolves. Second, an analogy is made with thermodynamics and the theory of Dissipative Structure is applied to CSS, which models the changing process of CSS from the disordered to the ordered. Third, the evolution of concept is analyzed based on the Dissipative Structure of CSS. Finally, the proposed method is verified by an application and experiments.
