The data for "What Makes Reading Comprehension Questions Easier?" (Sugawara et al., EMNLP 2018)

Easy and Hard subsets for machine reading comprehension datasets

Datasets

This repository now has easy/hard question ids and annotation data for the following datasets:

1. SQuAD (v1.1) [Rajpurkar et al., 2016]
2. AddSent [Jia and Liang, 2017]
3. NewsQA [Trischler et al., 2017]
4. TriviaQA (Wikipedia set) [Joshi et al., 2017]
5. QAngaroo (WikiHop) [Welbl et al., 2018]
6. MS MARCO (v2) [Nguyen et al., 2016]
7. NarrativeQA (summary) [Kočiský et al., 2018]
8. MCTest (160 + 500) [Richardson et al., 2013]
9. RACE (middle + high) [Lai et al., 2017]
10. MCScript [Ostermann et al., 2018]
11. ARC Easy [Clark et al., 2018]
12. ARC Challenge [Clark et al., 2018]

Easy and hard subsets

A json file consists as follows:

{question_id:
  {"f1"/"exact_match"/"rouge_l": [score],
   "predictions": [prediction]
  }
 question_id:
 ...
}

The score and prediction are made by the baseline system (BiDAF or GAR).

Validity and requisite skill annotation

Validity

• valid/invalid = 1/0
• multiple/single candidate = 1/0
• unambiguous/ambiguous = 1/0

Skills

Multi-labeling. if multiple labels are selected, we used the most bottom label to compute statistics

• 0 = word matching
• 1 = paraphrasing
• 2 = knowledge reasoning
• 3 = meta/whole reasoning
• 4 = math/logical reasoning

Multisentence reasoining or not = 1/0

Relations (single-labeling)

• 0 = coreference
• 1 = causal relation
• 2 = spatial temporal
• 3 = none

See the paper for the details.
