## Overview
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.
## Performance
Welcome to add performance report.
| Task | Language | Dataset | Score |
| -------------------------- | -------- | --------------------------- | ----- |

## Installation
The project is based on Python 3.6+, because it is 2019 and type hinting is cool.
| Backend | kashgari version | desc |
| ---------------- | -------------------------------------- | --------------------- |
| TensorFlow 2.2+ | `pip install 'kashgari>=2.0.2'` | TF2.10+ with tf.keras |
| TensorFlow 1.14+ | `pip install 'kashgari>=1.0.0,<2.0.0'` | TF1.14+ with tf.keras |
| Keras | `pip install 'kashgari<1.0.0'` | keras version |
You also need to install `tensorflow_addons` with TensorFlow.
