This API was used in creating the first semantic keyword research tool that can sort by relevance. Keyword research involves skimming through long lists of keywords to find the most relevant ones. This API makes keyword research quicker by auto sorting each keyword in the list by its similarity to a user-specified topic.

This is one of the many places where sorting a long list semantically helps.
