      Description


      Terrier 3.5
      org.terrier.matching.dsms.MRFDependenceScoreModifier.java
      linenumber : 68


      Regarding this MRFDependence scoring formula
      [linenumber68] return w_o * (Idf.log(1 + (tf/(mu * (defaultCf / super.numTokens))) ) + Idf.log(mu/(docLength+mu)));
      I'm worried about that first term(w_o) should be removed from this formula,
      because weight(w_o or w_u) will be combined in DFRDependenceScoreModifier.java

      Please check out above formula, and let me know if I'm wrong.

      Thank you.
