NoisyNER dataset

A dataset for evaluation of noisy label methods

About

NoisyNER is a dataset for the evaluation of methods to handle noisy labels when training machine learning models. It is from the NLP/Information Extraction domain and was created through a realistic distant supervision technique. Some highlights and interesting aspects of the data are:

Seven sets of labels with differing noise patterns to evaluate different noise levels on the same instances
Full parallel clean labels available to compute upper performance bounds or study scenarios where a small amount of gold-standard data can be leveraged
Skewed label distribution (typical for Named Entity Recognition tasks)
For some label sets: noise level higher than the true label probability
Sequential dependencies between the labels

Instructions

Clone this repository
Download the original Estonian NER dataset from https://doi.org/10.15155/1-00-0000-0000-0000-00073L .The official dataset seems to be non available at the moment (temporarily according to the authors), you can also download the file estner.cnll.zip here: https://code.google.com/archive/p/patnlp/downloads . Thanks to @WinterShiver for pointing this out.
Extract the downloaded .zip file and save the "estner.cnll" file in the "data" subdirectory
Run python prepare_data.py with Python3

You will then find in the "data" directory all the dataset files.

Structure

For each of the 7 noisy label sets, we provide the full dataset (with the file ending *_all.tsv) as well as an 80/10/10 train/dev/test split (with the file ending *_train.tsv/*_dev.tsv/*_test.tsv). The splits for the original, clean dataset are estner_clean_{train,dev,test}.tsv.

All files are tsv files with the same structure. The structure follows the CoNLL standard for NER datasets. Each line corresponds to one word or token. The first column gives the actual token. The last column gives the label. The two middle columns give additional, grammatical features which used to be leveraged by NLP methods but are often ignored by modern neural methods.
