 ## Data Programming & Weak Supervision
+### General ML
 - [Cleanlab](https://github.com/cgnorthcutt/cleanlab): A Python library for machine learning with noisy labels. It supports finding label errors in datasets and training models on noisily labeled data.
 - [Knodle](http://knodle.cc/): A modular Python framework that allows combining different classifiers, weak supervision approaches and denoising methods.
+
+### NLP
+- [skweak](https://github.com/NorskRegnesentral/skweak): A Python library to support weak supervision and labeling functions for sequence and text classification. 
+- [ANEA](https://github.com/uds-lsv/anea): A GUI and Python library to annotate NER tags via distant supervision for many languages and entity types.
+
+## Data Augmentation
+- [Albumentations](https://github.com/albumentations-team/albumentations): A Python library supporting more than 70 types of image augmentation and including support for bounding boxes and keypoints.
+- [nlpaug](https://github.com/makcedward/nlpaug): A Python libraries for data augmentation for text and signal data. 
+-  [TextAttack](https://github.com/QData/TextAttack): A Python library for adversarial attacks and data augmentation for NLP tasks.
