Translate Your Tweets In Real-Time Using Bluemix and Watson

Introduction

Let’s suppose that you want to write your tweets for different audiences. Bluemix Node-Red can easily fetch your posts from a primary Twitter account (in English, for example), translate the message and post the translated post to another Twitter account(s).

In order to create your twitter accounts, you need an email for each one. In this example, I’ve created gmail accounts for each twitter account.

Because red-node does not process all the tweets, we’ll use the hashtag #translate to trigger the translation process.

Add a Watson Language Translation API

Don’t forget to add the service to the node-red application, otherwise you’ll have to provide the service credentials manually.

Get a Node-Red instance

From the catalog, choose the Node-red starter boilerplate and create a new instance.

Then, open your node-red editor (url will be something like http://twittertranslation.mybluemix.net/red/ )

Create a flow like this

Configure the Inbound Twitter account

So the idea here is to fetch twitter posts from a master account (leoks_en), translate each post and send to another account (leoks_pt).

Double-click the first node on the left

Before adding the credentials, logout from any twitter account in your browser, so you can choose the right account.

I

Configure your translation node

Double click in the middle node (language translation) and configure the source and target languages

Give it a try

Now you have to deploy your flow

Now, let’s send a tweet using the leoks_en twitter account:

and here’s what we’ve got on the other side (leoks_pt)

Configure a filter (switch) to select only your own Tweets

Double-click the switch node (orange one) and set it like this:

Configure the Outbound Twitter Account

Double click on the node on the right, and choose the option to use a different credential

Conclusion

Node-red is incredibly easy to use and highly configurable and well integrated with Watson services.
