Comparison to Stanford Scene Graph Parser

berthyf96 opened this issue · 2 comments

Thanks for the great implementation. Does this function the exact same way as the Stanford Scene Graph Parser? If not, how is it different from the Stanford parser?

No. They are not identical. This repo tries to replicate only part of the results of the rule-based scene graph parser by Schuster et al, with a focus on the empirical performance.

It DOES cover all rules implemented in the Stanford Parser, with minor heuristic optimizations and extra rules for handling

  • compound nouns
  • phrasal prepositions such as "in front of"
  • phrasal verbs
  • detection of scene-level nouns (e.g., airport)

However, it does NOT cover some features of the Stanford Parser, including:

  • quantificational modifiers such as "a lot of"
  • pronoun resolution
  • plural nouns (see Sec. 3.1.3 of Schuster et al)

Thanks for the quick and detailed response!
