Using IBM Watson Tone Analyzer with Python

Here is a sample Python program that you can use to analyze the tone of text using IBM’s Watson Tone Analysis service on Bluemix. To get started with Bluemix you can sign up at http://bluemix.net. Feel free to use and modify the code as needed.

Slack Bot – Slack Channel Tone Analysis Using IBM Watson

In this video, I demonstrate how I used IBM Watson’s Tone Analyzer service to analyze an entire Slack channels’ textual content history. The bot allows you to select the channel you want to have analyzed and then presents charts displaying the various tones in the channel.

I’m Bringing IBM Bluemix and IBM Watson to the Classroom

I am very happy to announce that students enrolled in my “Intro to Programming and Problem Solving” class at Clark College in Vancouver, Washington will be using IBM Bluemix and IBM Watson this week in class. Students will be building a language translation program and a tone analyzer┬áprogram using the Python programming language.

Many thanks to IBM for their “Academic Initiative” program which makes it easy for educators to get access to IBM Bluemix for a limited time.

Students in my other programming language course will also soon be using Bluemix and Watson.

Stay tuned.
