Improved VSM algorithm for judging paragraph logic label
Xi Peng · Journal of Beijing Information Science & Technology University · 2014
In document format layout checking algorithm,it is impossible to compare a paragraph with many logical labels at same time to find the most similar logical label.Based on the prior VSM algorithm,membership tables for qualitative component quantization are designed based on the membership theory in fuzzy pattern recognition.The variation range and divergence change after standardization are analyzed.The standardization methods which suit the format vector is found.The standardization methods and similarity measurements are combined to analyze their outcomes,finding the suitable similarity measurements for standardization methods.Experiments show that,compared with prior algorithm,the improved algorithm can compare paragraph with any logical labels,decrease the information loss in standardization and similarity computation process.It significantly improves the logical label judging precision and recall rate,which is a suitable solution to vector similarity computation problems with many different kinds of components in one vector.
