Draft

Introduction

Rapidminer is both a free open source and commercial product for text mining (content analysis).

“RapidMiner provides data mining and machine learning procedures including: data loading and transformation (ETL), data preprocessing and visualization, modelling, evaluation, and deployment. The data mining processes can be made up of arbitrarily nestable operators, described in XML files and created in RapidMiner's graphical user interface (GUI). RapidMiner is written in the Java programming language. It also integrates learning schemes and attribute evaluators of the Weka machine learning environment and statistical modelling schemes of the R-Project.” (Wikipedia, retrieved 20:37, 13 March 2012 (CET))

Installation

Installation of RapidMiner Studio is very easy on Windows (tested on Windows 7 and Windows 8.1, both 64 bits), when using the Installer provided on your RapidMiner Account page.
Installation is kind of difficult on Mac OS X depending on Java versions. In 10.10, RapidMiner asks for Java 1.7 or above, even if you've got 1.8.X installed.

Note : RapidMiner is now a commercial software, so you can only use the product for 14 days, after asking a trial license.

A complete set of tools

First of all, it is important to say that RapidMiner Studio - and RapidMiner Server, that work with it - are a complete set of tools, rather than a more specific software. RapidMiner website says that "RapidMiner lets you easily sort through and run more than 1500 operations".

Because of it's complexity, i will only describe some of RapidMiner Studio's functions. However, I will show above an use example of RapidMiner Studio as a basic text miner. RapidMiner Studio's highlights are :

A visual - code-free - environment, so no programming needed
Available on all major operating systems and platforms

Main function : Design of analysis processes
Predictive analytics (with pre-made templates)
Data loading
Data transformation
Data modeling
Data visualization (with lots of visualizations)
Extension API

Lots of data sources : Excel, Access, Oracle, IBM DB2, Microsoft SQL, Sybase, Ingres, MySQL, Postgres, SPSS, dBase, Text files, and more
RapidMiner allows you to work with different types and sizes of data sources

Use example : text mining

As described before, RapidMiner can be used as a text mining software. I will describe here an example of text mining process, where we will :

Load and extract words from (the text files in) two directories
Ignore some words that are not wanted (stoplist)
Generate the results
View results

Launch RapidMiner Studio and load data

Fig.1 : Text Mining Extension

Fig.2 : The workspace

As you launched RapidMiner Studio (v. 6.1.1000) you will need to install the Text Mining extension. RapidMiner works with extensions that plug into the core system. The Text Mining extension can be found in RapidMiner Marketplace, which can be accessed from Help > Updates and Extensions (Marketplace) as shows the figure 1.

After restarting the software, we can start working with it. First of all create a New Process. You will see now the main window of RapidMiner Studio, and I will briefly describe the main zones of the working space :

In blue we have the main toolbar
In orange we can see all the operators that we can use in our processes
In green we have the repositories
In purple we have the main process windows, where we will be able to see process results and progression
In black we have parameters of each element of or process and help

From here, we will first of all find our operator Process Documents from Files (screenshot here) and we will drag it into the Process zone, in the center. At this point we have our operator in our process, and we need to set his parameters. Clic on our operator in the main process area, and see which parameters you can set on the right side. First parameter is text directories which we will set right away.

Fig.3 : Text Directories

Note : On the right side of your toolbar you can see a four-element menu that allows you to switch between Design and Results (also with F8 and F9 keys) that will be very useful. If your results aren't what you were expecting, or you made a mistake when designing your process, you can easily return from the results to the design area.

In my case, i have a directory on my Desktop which name is "data"
In /data/, I have /litterature/text1.txt and /photographie/text2.txt
I will set up my text directories like suggested in the Fig. 3 and give both a different name to be able to show results depending on text directory

In next section we will talk about operators, and we will come back to Process Documents from Files parameters to choose which vector we want RapidMiner to create.

Tokenize & define StopWords

Now that we have our Process Documents from Files operator in our Main Process area and our text directories set up correctly, we need to connect our operator Process Documents from Files on the left (from inp to wor) and on the right (from exa to res, and wor to res). This will allow the data to be processed.

Fig. 5 : Tokenize and Stopwords operators

We will now define what steps (or processes) should be executed during our Process Documents from Files operator. So by double-clicking on it, we can see it's inside. We will now add a Tokenize operator that can be found in operators area (in Tokenization) on the left. Tokenize will separate words making them independent values. One of RapidMiner big values is that graphic user interface, that allows you to build processes quite naturally. We will also be able to add Filter Stopwords (french) - because my text files are in french - into our main Process Documents from Files operator, also by dragging it. You should see something like in Fig. 5 above.

View result

If your main operator is connected (input - output) and that inside of it, your Tokenize operator and your Stopwords operator are also connected to each other, and to input and output as suggests the figure above, you should be ready to launch the process which should generate your results.

Before clicking on the launch button, i want to make you notice that we didn't change the Vector Creation parameter of our Process Documents from Files. That parameter allows you to set the type of visualization you want the software to create from the data given.

If you launch the process leaving the default value (TF-IDF), RapidMiner will present you the results in different ways. First you have two tabs, WordList and ExampleSet.

WordList View

Fig. 6 : WordList View

In the WordList view tab (Fig. 6) we have an occurrences analysis.

First column presents the words found in documents
Second column presents the attributes of words (which in my case are equal to the words themself)
Third column shows Total Occurences (how many times we can find the word in all documents)
Fourth column shows Document Occurences (in how many documents we can find the word)
Fifth and sixth column shows Text Directory Occurences (how many times we can find the word in each text directory)

ExampleSet View

Fig. 7 : ExampleSet View

Fig. 8 : Charts view types

In the ExampleSet view tab (Fig. 7) we have a left menu with five tabs. I will try to present them :

First tab is an Overview of the process. We can find there each text directory, each document processed and some other informations.
Second tab is Statistics, and allows you to see statistics about the data given.
Third and fourth tabs are Charts and Advanced Charts and allows the user to visualize some default charts, or build advanced and customized charts that feed in the data and analysis results of our text mining process.
Fifth tab allows the user to save annotations into the process.

Note : Fig. 8 shows you some of the charts view types that RapidMiner proposes.

Export results

When it comes to export results in RapidMiner Studio, each extension and RapidMiner Studio function will allow to do different sort of things. For example, after a text mining process, data will be available in different forms :

WordList view will allow you to export the spreadsheet in image (png, svg, jpg, eps, pdf), to print it, or you can even copy/paste the spreadsheet data into Microsoft Excel or Google Drive Spreadsheets.
ExampleSet view also allows the user to copy/paste the data from the software, to print it or to export it as an image.

Note : The export as an image function seems to allow you to export all software main area (in the center) but not to export individually an image.
