LRTA_Perturbed_Dataset

This repository contains the perturbed datasets (val and testdev) presented in the paper- LRTA: A Transparent Neural-Symbolic Reasoning Framework with Modular Supervision for Visual Question Answering (NeurIPS 2020)
The zip files contain masked (attribute and relationships) version of the GQA evaluation dataset. (https://cs.stanford.edu/people/dorarad/gqa/download.html). Mask term used is "XXXunknownXXX", the json structure remains the same as the original dataset with an extra field "question_orig" that denotes the original unmasked question.

Format

  • attribute_masked_data.zip
    • val_balanced_attribute_masked_questions.json
    • testdev_balanced_attribute_masked_questions.json
  • vrb_prpn_masked_data.zip
    • val_balanced_vrb_prpn_masked_questions.json
    • testdev_balanced_vrb_prpn_masked_questions.json

Snippets from data generation code

The below snippets give a broad overview of the masking procedure used to generate the perturbed datasets, the question mentioned in the functions is a string containing the question text.

Attribute masking

#ATTRIBUTES is a list of attributes obtained from https://github.com/wenhuchen/Meta-Module-Network/blob/master/Constants.py
MASK_TOKEN = "XXXunknownXXX"

def mask_attributes(question):
  for word in question.split(" "):
    if word in ATTRIBUTES:
      masked_question = question.replace(word,MASK_TOKEN) 
  return masked_question        

Relationship masking

MASK_TYPES = ('VERB', 'ADP') #verbs and prepostions are masked to capture relationships
pos_tagger = spacy.load("en_core_web_sm") #spacy POS Tagger is used
MASK_TOKEN = "XXXunknownXXX"

def mask_relationship(question):
    tagged_dict = pos_tagger(question)
    masked_question = " ".join([ x.text if x.pos_ not in MASK_TYPES else MASK_TOKEN for x in tagged_dict])
  return masked_question
