As a computational linguistics grad student I find Pearson's "product" line completely mind-boggling, and their peddling it deserving a giant class-action lawsuit. Consider that the state of the art in machine representation of words is something around Word2Vec or GLoVe, and that we have some okay dependency parsers. That their system provides scores consistent with human raters is likely just evidence that they have a coarse-grained and noisy human evaluation system.
