Despite the fact that F1 score will be the extensively utilized metric on account of its balancing mother nature, other parameters which include precision (which is efficacious in the event the dataset is balanced) and precision (to watch the overhead) ought to be used for comparison Together with the baseline classifier.
Beneath the consistent strain of lingering distress, it can become virtually difficult to acknowledge the possibilities that continue on being. This tunnel eyesight will help make suicide appear to be not only a method out but the only true
Then, especially for each dataset Di for use in Ei, two extra features were being extracted: doc phrase matrix for title (Tit) and document phrase matrix for publish overall body (Tib). See Multimedia Appendix 2 to get a diagram of feature extraction along with the experiment design and style measures.
