Lab 4 Using Sentiment Analysis in MobileFirst Quality
Assurance
In this lab, you will use the MobileFirst Quality Assurance to perform a sentiment analysis. As you might
already know that almost all of the apps are being rated and users are actively using the app store rating
system to provide their feedback. Sentiment analysis can evaluate the feedbacks that the millions have
provided through the app store rating system.
3.1 Quick overview of MobileFirst Quality Assurance on Bluemix
MobileFirst Quality Assurance can be run on premise or off premise (on BlueMix).
IBM® Bluemix™ is a software as a service (SAAS) platform. It has a growing number of IBM software
and non-IBM software on the BlueMix platform. The Bluemix SAAS platform is open standard and cloud
based - it enables any vendors to expose their software as SAAS. Without the hassle of installing and
configuring any hardware and software, you can use the Bluemix platform to support your project. The
capabilities on the Bluemix platform covers a wide range from development, management, operation,
performance, monitoring and deployed runtimes and it is not limited to just IBM software. Some example
of the continuous growing capabilities in Bluemix include:
• Workflow
• WAS Liberty for Java
• Cloudant Mobile Data
• PHP (community)
• SDK for Node JS
• Twilio (3rd party)
• BlazeMeter (3rd party)
• Dev/Op
• Mobile Quality Assurance
• And a lot more!!
We will be using the Mobile Quality Assurance capability on Bluemix for this lab.

feedback with sentiment analysis, over-the-air build distribution, automated crash reporting, in-
app bug reporting and user feedback.

if the user doesn’t leave many words in their feedback, that feedback will be evaluated with
lower priorities.
