"How to do text classification only by java code"

lucky_q

Hi all,

I am new to RapidMiner communuty. Recently, I'm planning to use Rapidminer for text classification. I want to develop a small demo system (which means do not write xml file) in order to get familiar with the source code of Rapidminer. I tried rapidminer5.0 at first, as there isn't enough documentation and sample for rapidminer5.0, I decided to use 4.6 instead. Unfortunately, I still do not know how to finish that only by java code.

I meet 2 problems :

1: Which operator could help me in transforming all the original messages stored in particular folder into single file which contains the word vector or feature vector. I know the Text Processing plugin, but I'm not sure how to do that from reading original file and only using java code. could anybody show me how to do that?

2: For training the feature vector, which is the easiest way for me to do if I want to use only java code? Is there any sample code could show me how to reading a feature vector file and generate a mod file. (like using weka)

I know these are all stupid questions, it's just I have know idea how to do this. I would be very very appreciated if somebody could give me some sample code (for rapidminer4.6) to show me how the whole process work. Thanks.

Thank you so much. I'm so sorry to post this subject in two different places.

Is there any sample java code for that? does rapidminer 4.6 could use weka 5.0 plugin? I have no idea how to implement them.

Thanks, again.
