The cleanlab package has been extended to entity recognition tasks, which involves annotating each word in a sentence with its corresponding label. The cleanlab package can now identify label errors in token classification data, including the CoNLL-2003 dataset, which is commonly used for benchmarking entity recognition models. The code provided by cleanlab allows users to easily find and fix issues in their datasets, using an open-source algorithm that has been proven to be effective in detecting label errors. The package also provides additional functions to help understand the dataset better, such as identifying the most commonly mislabeled words and determining what types of labels are most frequently assigned incorrectly. Overall, cleanlab is a useful tool for improving text data quality and developing reliable machine learning models.
