Sentence Structure Identification - Spacy

I intend to identify the sentence structure in English using spacy and textacy. For example: The cat sat on the mat - SVO , The cat jumped and picked up the biscuit - SVV0. The cat

Solution 1:

Issue 1: The SVO are overwritten. Why?

This is textacy issue. This part is not working very well, see this blog

Issue 2: How to identify the sentence as SVOO SVO SVVO etc.?

You should parse the dependency tree. SpaCy provides the information, you just need to write a set of rules to extract it out, using .head, .left, .right and .children attributes.

>>for word in text: 
    print('%10s %5s %10s %10s %s'%(word.text, word.tag_, word.dep_, word.pos_, word.head.text_))

I recommend you look at this code, just add pobj to the list of OBJECTS, and you will get your SVO and SVOO covered. With a little fiddling you can get SVVO also.
