Contributor II
Hello!
I'm new in this forum. i'm from Chile. I want know if you can help me about how integrating rapidminer in netbeans. I need run the API of Rapidminer in Netbeans for can be classify text. I took the software of Rapidminer to create a model and now need read the model, and can be apply this model to unlabeled data. I searched for more web pages, but unfortunately to no avail. I hope you can help, because, is for my project to my degree of engineer in informatic and computer.
thank you very much
This is what I have:
import com.rapidminer.operator.ModelApplier;
import com.rapidminer.operator.Operator;
import com.rapidminer.operator.io.ModelLoader;
import com.rapidminer.tools.OperatorService;
public static void main(String args[]) {
com.rapidminer.RapidMiner.setExecutionMode(com.rapidminer.RapidMiner.ExecutionMode.EMBEDDED_WITHOUT_UI);
System.setProperty("rapidminer.home", "/rapidminer");
System.setProperty(com.rapidminer.RapidMiner.PROPERTY_RAPIDMINER_INIT_PLUGINS_LOCATION, "/rapidminer/lib/plugins");
com.rapidminer.RapidMiner.init();
try {
com.rapidminer.Process p = new com.rapidminer.Process();
Operator ApplyModelo= OperatorService.createOperator(ModelApplier.class);
p.getRootOperator().getSubprocess(0).addOperator(ApplyModelo);
ModelLoader readmodel = OperatorService.createOperator(ModelLoader.class);
readmodel.setUserDescription("leermodelo");
readmodel.setParameter("model_file", "C:\\Users\\Monitos\\Documents\\modeloOut.mod");
p.getRootOperator().getSubprocess(0).addOperator(readmodel);
connect(readmodel,"out",ApplyModelo,"mod");
} catch (Exception ex) {
Logger.getLogger(test.class.getName()).log(Level.SEVERE, null, ex);
}
}
this is the error:
