Select candidate words of descriptors in the field of digital communication based on the relationship intensity among co-words and the frequency of keywords by calculating the relationship intensity among co-words. Then compare the result with that just based on the frequency of keywords, showing that the candidate words of descriptors selected based on the relationship intensity among co-words and the frequency of keywords are better than those just based on the frequency of keywords.
