  • In dependency parsing of long sentences with fewer subjects than predicates, it is difficult to recognize which predicate governs which subject. To handle such syntactic ambiguity between subjects and predicates, this paper proposes an 'S-clause' segmentation method, where an S(ubject)-clause is defined as a group of words containing several predicates and their common subject. We propose an automatic S -clause segmentation method using decision trees. The S-clause information was shown to be very effective in analyzing long sentences, with an improved parsing performance of 5 percent. In addition, the performance in detecting the governor of subjects was improved by $32\%$.
