RapidMiner Day One: Introduction and Installation

by | May 18, 2015

This is the first in a series of blogs about me learning to use RapidMiner with Shaun McGirr who is one of OptimalBI’s Analytical Modellers and a RapidMiner expert.

What is my goal?

As OptimalBI’s community manager I spend a lot of time and effort on Twitter sharing relevant content to our audience of people in the BI space. I want to get an understanding of how to engage with our audience in the future. I’m hoping RapidMiner can help me understand this by predicting which Tweet will be the most viewed in future based on what has been popular in the past.

Why RapidMiner?

Shaun McGirr is an Analytical Modeller who has recently completed RapidMiner training. If he can teach me to use RapidMiner it will show that it is a tool can be deployed by Analytical Modellers to users like me who have a goal but are not analytically trained. This will mean that Analytical Modellers can move on to other stuff rather than crunch data for people like me.

Getting started

In order for me to start actually using RapidMiner to I needed to download and install it. So here is my first day of doing just that.
As with most software there are there are prerequisites that you need to have sorted.
RapidMiner is written in Java so it looks and behaves the same regardless of the operating system it’s running on. That means you need Java on your machine, and it’s probably there already but needs to be up to date. If you’re installing to a Mac, you’ll need both the Java JRE and the Java JDK for RapidMiner to work.
Conveniently both can be downloaded for free from Oracle. You can get them as shown below.
1) Java Runtime Environment here
2) Java SE Development Kit because Java RE will work better with this, here.
I required some help from Shaun to sort this out but it is a one time job so that isn’t a real problem, also these are only for Mac users and won’t be required for Windows machines.
Once that has been taken care of installing RapidMiner itself is very easy.

  1. Visit the RapidMiner website.
  2. Click on Getting Started.
  3. Use my email address to create an account.
  4. Go to Licences and Select Trial Licence which gives me 14 days to try out RapidMiner Professional before it revert to the RapidMiner Starter.
  5. Agree to licence terms.
  6. Go to Downloads and select Macintosh because that is the type of computer I use, download.
  7. Open RapidMiner Studio. Ensure that your system preferences allow the opening of programs from the internet.

RapidMiner has excellent documentation here.
From that you are greeted with this screen:

Next time I will be working my way through RapidMiner’s online tutorials to get a feel for how it work and how I can use it to analyse my Twitter data.
See you then.
