Abstract:

The primitive in the different formats needs to be associated by the primary key. According Heinz, Hartmut and Dietmars weighted information theory, we use a different way to deal with it. Based on the idea, we construct WEMFBCDNM(Weighted Entropy Model Based on Fractal Box Counting Dimension and  Natural Measure), which is more suitable for the vector diagram format. Comparing with the traditional algorithms,this method has improved its performance to a certain extent.

Key words: information theory, vector diagram format, box dimension, natural measure
