+## 1. Zero-shot Text Classification
+
+This project provides an end-to-end application solution for universal text classification based on Universal Task Classification (UTC) finetuning and goes through the full lifecycle of **data labeling, model training and model deployment**. We hope this guide can help you apply Text Classification techniques with zero-shot ability in your own products or models.

+
+Text Classification refers to assigning a set of categories to given input text. Despite the advantages of tuning, applying text classification techniques in practice remains a challenge due to domain adaption and lack of labeled data, etc. This PaddleNLP Zero-shot Text Classification Guide builds on our UTC from the Unified Semantic Matching (USM) model series and provides an industrial-level solution that supports universal text classification tasks, including but not limited to **semantic analysis, semantic matching, intention recognition and event detection**, allowing you accomplish multiple tasks with a single model. Besides, our method brings good generation performance through multi-task pretraining.
+
+**Highlights:**
+
+- **Comprehensive Coverage**🎓: Covers various mainstream tasks of text classification,  including but not limited to semantic analysis, semantic matching, intention recognition and event detection.
+
+- **State-of-the-Art Performance**🏃:  Strong performance from the UTC model. with good zero-shot and few-shot performance.
+
+- **Easy to use**⚡: Three lines of code to use our Taskflow for out-of-box Zero-shot Text Classification capability. One line of command to model training and model deployment.
+
+- **Efficient Tuning**✊: Developers can easily get started with the data labeling and model training process without a background in Machine Learning.

+
+## 2. Quick start
+
+For quick start, you can directly use ```paddlenlp.Taskflow``` out-of-the-box, leveraging the zero-shot performance. For production use cases, we recommend labeling a small amount of data for model fine-tuning to further improve the performance.

+
+### 2.2 Data labeling
+
+We recommend using [Label Studio](https://labelstud.io/) for data labeling. You can export labeled data in Label Studio and convert them into the required input format. Please refer to [Label Studio Data Labeling Guide](./label_studio_text_en.md) for more details.
+
+Here we provide a pre-labeled example dataset `Medical Question Intent Classification Dataset`, which you can download with the following command. We will show how to use the data conversion script to generate training/validation/test set files for fine-tuning.
+
+Download the medical question intent classification dataset:
+
+```shell
+wget https://bj.bcebos.com/paddlenlp/datasets/utc-medical.tar.gz
+tar -xvf utc-medical.tar.gz
+mv utc-medical data
+rm utc-medical.tar.gz
+```
+
+Generate training/validation set files:
+
+```shell
+python label_studio.py \
+    --label_studio_file ./data/label_studio.json \
+    --save_dir ./data \
+    --splits 0.8 0.1 0.1 \
+    --options ./data/label.txt
+```
+
+For multi-task training, you can convert data with script seperately and move them to the same directory.

+
+### 2.3 Finetuning
+
+Use the following command to fine-tune the model using `utc-large` as the pre-trained model, and save the fine-tuned model to `./checkpoint/model_best/`:

+
+### 2.6 Deployment
+
+We provide the deployment solution on the foundation of PaddleNLP SimpleServing, where you can easily build your own deployment service with three-line code.
