The syntax analysis is incorrect

[udnaan]

When comparing the analyzed syntax with a state of the art model such as google nlp api, the analysis is not quite correct. Take for instance a sentence such as the house had thick and wide stone walls
On the demo page (and using the nodejs module), the syntax outputs the wide and stone as a MWE, part of the walls. Which is incorrect.

Using google nlp, the syntax output for the same sentence is wide is conj and stone is nn, which is correct.
