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

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 format… I propose that an OO modeling of it should be
named the Attribute-Relation Graph Hierarchy

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.
