We represent the normalization function by N orm(•).
for the substring c j 1 (j ∈ [1, J)) in c J 1 of the sentence tuple <e I 1 , c J 1 , a K 1 >, assuming that one of its candidate segmentations is , the feature score of the inner log-linear model is derived as follows: where f k (n) represents the phrase-level features.
