Contrasting Human- and Machine-Generated Word-Level Adversarial Examples for Text Classification

This repository contains the data collected for our EMNLP 2021 paper Contrasting Human- and Machine-Generated Word-Level Adversarial Examples for Text Classification.

Human- and machine-generated adversarial examples

The human- and machine-generated adversarial examples are in the file collected_adversarial_examples.csv. The file contains 1020 rows, representing the 170 sequences unperturbed and perturbed with each of the 5 attacks.

The columns are as follows:

• id: the sequence ID, which also identifies the attack used (or no attack)
• text: the corresponding text
• succ: whether the adversarial examples successfully flipped the classifier label
• label: the actual ground truth label of the sequence
• num_queries: the number of queries needed to generate the adversarial example
• sub_rate: the word substitution rate

Collected data

Stage one

The raw collected data from the crowdsourcing experiments corresponding to Task 4 of the first data collection stage (see Section 3.1 in the paper) can be found in task_4.json.

Stage two

The collected ratings for each generated adversarial example can be found in ratings.json. For each rated text, the JSON provides the total amount of ratings for both naturalness and sentiment. For both criteria, the ratings are on a scale from 1 (very negative sentiment/very unnatural) to 5 (very positive sentiment/very natural).
