> Below I will use "Recognize Clinical Entities" model as example **↓**.
### **Recognize Clinical Entities Demos**
> **Multiple demos are actually presented for one NLP model, find more demos [here](https://nlp.johnsnowlabs.com/diagnoses_procedures).**

> Use "Detect clinical entities in text" as example to continue **↓**"

### **Detect Clinical Entities in Text**
#### **Live Demo**
> **Content page showing the model's functionality. Link available [here](https://demo.johnsnowlabs.com/healthcare/NER_CLINICAL/)**

> * **There are also online Colab samples (IPython Notebook) available [here](https://colab.research.google.com/github/JohnSnowLabs/spark-nlp-workshop/blob/master/tutorials/Certification_Trainings/Healthcare/1.Clinical_Named_Entity_Recognition_Model.ipynb)**
> * Tutorials to run the demo are presented in the page(shown below).

> * The model is required a product key from John Snow LABs to start.

> * **The product key (JSON file) can be uploaded in two ways(shown below)**![](https://i.imgur.com/AUN7WrM.png)
> Note that we may need to rename the JSON file base on the colab code, I found that they are using different filenames to read the JSON across different demos.


### **Detect Sentence Similarity**
> **Without Lisence(product key), we can still try out one of their free models to get a taste of how these demo works. Demo link available [here](https://colab.research.google.com/github/JohnSnowLabs/spark-nlp-workshop/blob/master/tutorials/streamlit_notebooks/SENTENCE_SIMILARITY.ipynb#scrollTo=TA21Jo5d9SVq).**
