For the interpretation of relationship major and minor categories, this matrix was standard and based on the similarity was interred to XL.STAT Software. The terms were optimized in 7 clusters. For the next steps of analysis has been used from MATHLAB software, and for display coword network from Pajak software. The results of this research show that Cluster 2 by 10, and Cluster 4 by 9 terms, are known as the principal clusters. The Cluster 5 has the most of selective terms from the major categories and Cluster 2 & 1 have minimum distance that it shows the relationship between the major and minor topics in these clusters is higher.
