It was highlighted that the original article [1] contained an error in the Quantitative evaluation of Methods. A bracket was misplaced in the formula. This Correction article shows the incorrect and correct formula.

  • Incorrect formula

  • $$ {\text{Recall}} = \left( {{{\text{TP}} \mathord{\left/ {\vphantom {{\text{TP}} {{\text{TP}} + {\text{FN}}}}} \right. \kern-0pt} {{\text{TP}} + {\text{FN}}}}} \right) \cdot 100 $$
  • Correct formula

  • $$ {\text{Recall}} = {{\text{TP}} \mathord{\left/ {\vphantom {{\text{TP}} {\left( {{\text{TP}} + {\text{FN}}} \right)}}} \right. \kern-0pt} {\left( {{\text{TP}} + {\text{FN}}} \right)}} \cdot 100 $$
