The semantic analysis system can automatically tag semantic class for each word and analyze the semanticdependency structure between words with the precision of 90.85% and 75.84% respectively.
This enables semantic queries to target individual elements of the service metadata, and meaningful dependency analyses to take place prior to making changes.
