Is there a method to determine the ideal amount of Keywords, High Frequency Terms and High Key Terms for the Keygraph?
To determine the ideal amount of topics for the LDA you have Topic Coherence or Perplexity. Is there something similiar for KeyGraph?
I don’t know of a method to determine these parameters, unfortunately.
However, you could read the paper which describes the KeyGraph algorithm. Maybe you’ll find some more information there, which helps to optimize your outcome. Here is the link to the paper: http://sclab.yonsei.ac.kr/courses/06mobile/4-1.pdf
