Kashgari is a simple and powerful NLP Transfer learning framework, build a state-of-art model in 5 minutes for named entity recognition (NER), part-of-speech tagging (PoS), and text classification tasks.

  • Human-friendly. Kashgari's code is straightforward, well documented and tested, which makes it very easy to understand and modify.
  • Powerful and simple. Kashgari allows you to apply state-of-the-art natural language processing (NLP) models to your text, such as named entity recognition (NER), part-of-speech tagging (PoS) and classification.
  • Built-in transfer learning. Kashgari built-in pre-trained BERT and Word2vec embedding models, which makes it very simple to transfer learning to train your model.
  • Fully scalable. Kashgari provides a simple, fast, and scalable environment for fast experimentation, train your models and experiment with new approaches using different embeddings and model structure.
  • Production Ready. Kashgari could export model with SavedModel format for tensorflow serving, you could directly deploy it on the cloud.

Our Goal

  • Academic users Easier experimentation to prove their hypothesis without coding from scratch.
  • NLP beginners Learn how to build an NLP project with production level code quality.
  • NLP developers Build a production level classification/labeling model within minutes.
