How to evaluate the model performance ?

Open Yazooliu opened this issue 6 years ago • 0 comments

When use tf-idf model to extract keywords in comments from taobao or tianmao.

  1. How to evaluate your model performance is good or not ?
  2. How did you know the keywords extracted from comments can reflect the main topic of user comments ?

Thanks ..
