Abstract:

Based on summarising and analyzing the research status of policy research and the technology of concept description, this paper proposes an effective mining method of recessive lineage relationship between policies. This method introduces the theory of factor space and gives a method for decomposing concept factor. We introduce the recessive gene as a new "synonym" and calculate the fitting degree of policy texts to reveal the recessive lineage relationship, which cannot be reflected through the direct calculation of similarity. Finally, we use the articles of law as the set of policy texts to carry out a large number of experiments. The comparison and analysis of the experimental results verify the effectiveness of the proposed method.
