# Tweet Sentiment

This is an addition to Tweet Simple where it takes the output from the function and does sentimental analysis on the tweet and provides a sentimental score . This then prints the score on the debug panel as well as the Positive Tweet or Negative Tweet

## How to Build this Flow

### Step 1: Copy The flow from Tweet Simple

Copy the flow from Tweet Simple and paste nodes into this new project

### Step 2. Insert Sentiment Analysis node

Insert the Sentiment node from the analysis palette and name node. Connect sentiment node to the output of the function node from Tweet Simple

### Step 3. Insert Switch Node and Debug Node

1. Insert switch node and connect it to Sentiment node. Name the property **msg.sentiment.score :**
2. Name the Switch Statement - Positive / Negative Tweets
3. A value of greater or equal to 2 will output positive tweets 
4. A value of less than 0 will output negative tweets

1. Insert a debug message node and connect it to Sentiment node. Name the property **msg.sentiment.score :**

### Step 4. Insert Debug nodes for Positive & Negative Tweets

Insert debug nodes

* Name one Debug Node : Positive Tweets  
* Name another Debug Node : Negative Tweets 

Make sure both nodes output is msg.payload

### Step 5 : Deploy

You should be able to see the tweet output and sentiment score on the debug pannel
