C4.5 for keyphrase Extraction

Postby hadyhady » Sun May 10, 2009 8:46

Hi All,

I need some help, now I'm doing my final project in my campus, the topic is Kephrase Extraction , I'm using C4.5 for the algorithm, but the result of my program is very bad.

I'm using 2 step for training process :
1. Pre-process include stemming, attribute weighting ( like tfidf, number of terms, first occurrence, is_noun)
2. Train or create a tree

I'm using 2 steps for testing process :
1. Pre-process include stemming, attribute weighting ( like tfidf, number of terms, first occurrence, is_noun)
2. Applied rule from training.

Is there anyone who knows about keyphrase extraction?

The second question is, why I can't build :"ensemble.c" , the error said can not read ensemble.obj ? What's wrong here?

Thanks a lot
