Took me 1 hour to create 1 object/concept and the visitor. My classmates probably did it with Python but not in the spirit to share it so I guess it took them less time but it is not reusable... :) Then some time to document, write the baseline and the mail.

Hello Julien, I am curious to know how much faster/slower you can do this vs people using other languages. So?

So, ARFF is the file formatâ¦ I propose that an OO modeling of it should be named the Attribute-Relation Graph Hierarchy :D On 25 April 2016 at 13:37, Julien Delplanque <julien(a)tamere.eu> wrote: > Hello everyone, > > For a university project in ''Datamining and Datawarehousing'', I have to > convert data stored as text files in different formats to the Weka[1] ARFF > format[2]. > > I did it with Pharo of course! :) > > So, I wrote this little project [3] to share what I have done with you, > just in case someone else needs to export data from Pharo objects to an > ARFF string for further analysis with Weka. > > Cheers, > > Julien > > Links: > > [1] Weka's website: http://www.cs.waikato.ac.nz/ml/weka/ > > [2] ARFF format spec: https://weka.wikispaces.com/ARFF > > [3] Arff generator for Pharo: https://github.com/juliendelplanque/Arff > > > >

[ANN] Arff generator for Pharo

by Julien Delplanque

Hello everyone, For a university project in ''Datamining and Datawarehousing'', I have to convert data stored as text files in different formats to the Weka[1] ARFF format[2]. I did it with Pharo of course! :) So, I wrote this little project [3] to share what I have done with you, just in case someone else needs to export data from Pharo objects to an ARFF string for further analysis with Weka. Cheers, Julien Links: [1] Weka's website: http://www.cs.waikato.ac.nz/ml/weka/ [2] ARFF format spec: https://weka.wikispaces.com/ARFF [3] Arff generator for Pharo: https://github.com/juliendelplanque/Arff
