Yes, the press release is (actually) pretty difficult to parse and really opaque in how the comparison is measured, which is why I wanted to throw into question the blog&#x27;s headline, &quot;The World&#x27;s Most Accurate Parser.&quot; It seems more clear now but obviously Google doesn&#x27;t feel the need to overtly prove that they are the best in the world at tasks, which is a bit questionable considering their number of followers. In all, it seems they have tested against several other dependency parsers, but clearly not all of them, and it&#x27;s fair to say that it is &quot;highly accurate,&quot; but this parser still falls victim to some of the same issues that most statistical parsers do, and while faster than some dependency parsers, it is not faster than all of them.<p>The point about overfitting is valid, too, which is another reason why this &quot;most accurate such model in the world&quot; claim is obnoxious.<p>It&#x27;s also fair to note that their advance is in fractions of percentage points on this specific dataset over models that are 5-10 years older.
