For example , in the OLW lexicon , when two people'sometimes but not always a man and a woman'agree that they Lword one another , they often enter into one of the Cwords , which leads perhaps eventually to the M-word , which in turn authorizes them to F-word with the sanction of church and state .
Case in point : using the OLW lingo , when a couple ( regardless of the gender makeup thereof ) Lword each other , it can lead them to a Cword , which may lead to the Mword , allowing them to F-word with divine and governmental permission .

The answer has nothing to do with their cause , however , but with the simple fact that dictionaries are not exercises in bi-unique substitutability ; in other words , if one of the senses of run is operate ' ( as in She runs an engine factory ) , that does not make it valid to assume that one can substitute operate for run in We run in the marathon every year . Although recognizing this as a shortcoming of dictionaries and assigning it arbitrarily to what , for lack of a better term , we might call the genius of the language , might seem trivial to the casual observer , it is a valid matter for concern in the realm of lexicology .
The answer given is irrelevant to their cause .

## Overview

Original dataset is available in the original Github repo.

This dataset is a collection of NLI benchmarks constructed as described in the paper An Empirical Study on Model-agnostic Debiasing Strategies for Robust Natural Language Inference published at CoNLL 2020.

## Dataset curation

No specific curation for this dataset. Label encoding follows exactly what is reported in the paper by the authors. Also, from the paper:

all the following datasets are collected based on the public available resources proposed by their authors, thus the experimental results in this paper are comparable to the numbers reported in the original papers and the other papers that use these datasets

Most of the datasets included follow the custom 3-class NLI convention {"entailment": 0, "neutral": 1, "contradiction": 2}. However, the following datasets have a particular label mapping

• IS-SD: {"non-entailment": 0, "entailment": 1}

• LI_TS: {"non-contradiction": 0, "contradiction": 1}

## Dataset structure

This benchmark dataset includes 10 adversarial datasets. To provide more insights on how the adversarial datasets attack the models, the authors categorized them according to the bias(es) they test and they renamed them accordingly. More details in section 2 of the paper. A mapping with the original dataset names is provided below

Name Original Name Original Paper Original Curation
0 PI-CD SNLI-Hard Gururangan et al. (2018) SNLI test sets instances that cannot be correctly classified by a neural classifier (fastText) trained on only the hypothesis sentences.
1 PI-SP MNLI-Hard Liu et al. (2020) MNLI-mismatched dev sets instances that cannot be correctly classified by surface patterns that are highly correlated with the labels.
2 IS-SD HANS McCoy et al. (2019) Dataset that tests lexical overlap, subsequence, and constituent heuristics between the hypothesis and premises sentences.
3 IS-CS SoSwap-AddAMod Nie et al. (2019) Pairs of sentences whose logical relations cannot be extracted from lexical information alone. Premise are taken from SNLI dev set and modified. The original paper assigns a Lexically Misleading Scores (LMS) to each instance. Here, only the subset with LMS > 0.7 is reported.
4 LI-LI Stress tests (antonym) Naik et al. (2018) and Glockner et al. (2018) Merge of the 'antonym' category in Naik et al. (2018) (from MNLI matched and mismatched dev sets) and Glockner et al. (2018) (SNLI training set).
5 LI-TS Created by the authors Created by the authors Swap the two sentences in the original MultiNLI mismatched dev sets. If the gold label is 'contradiction', the corresponding label in the swapped instance remains unchanged, otherwise it becomes 'non-contradicted'.
6 ST-WO Word overlap Naik et al. (2018) 'Word overlap' category in Naik et al. (2018).
7 ST-NE Negation Naik et al. (2018) 'Negation' category in Naik et al. (2018).
8 ST-LM Length mismatch Naik et al. (2018) 'Length mismatch' category in Naik et al. (2018).
9 ST-SE Spelling errors Naik et al. (2018) 'Spelling errors' category in Naik et al. (2018).
