dataset and coding problem

bangbadabang

Hi,

I have to cluster texts (course lectures) into different categories using hierarchical clustering.
My data input is from mysql database.

1st question, what format does my data have to be in?

I also need to connect RM with the system I work for (nonprofitable org), to trigger it to run automatically after a certain period.
But I have problem with the coding..
I have looked into the documentation, but it's really confusing..
Could you suggest me on where to and what functions in which location that does :
load the data
pick learner type
construct the output model

Thanks so much!

You can read the data directly from your database, e.g. using a DatabaseExampleSource. Just make sure your texts are marked as Sting attributes. Use a Nominal2String operator for that purpose.

Probably the easiest method would be not do any coding at all. Just setup a process that does the work, use cron or whatever scheduler you will be using to trigger a call to RapidMiner <yourprocess.xml>. If that does not suit your needs, you would have to be more specific about what your problem is and what confuses you. The functions you are asking for are done in the respective operators' apply methods. What operators these are depends only on your choice.
