Table 2 Results for the gene-disease corpus.

From: Extraction of semantic biomedical relations from text using conditional random fields

  Recall Precision F-score
Dictionary + naive rule-based 43.31 42.98 43.10
CRF + naive rule-based 67.62 71.88 69.68
one-step CRF 73.36 78.66 75.90
cascaded CRF 76.61 79.46 78.00
CRF + SVM 76.63 79.48 78.03
  1. NER and SRE performance comparison of one-step and cascaded CRF with three benchmark methods. The cascaded CRF is on par with the CRF+SVM model, where the latter one requires an expensive preceding feature selection step.
