Optimization of Candidate Topic Clause Evaluation Function in Topic Clause Identification

Topics were often omitted in the beginning of Chinese punctuation clause(abbreviated as PC).In order to better recover topics more accurately,an improved candidate topic clause(abbreviated as CTC) evaluation function was proposed in the topic clause(abbreviated as TC) identification task.Both the context similarity and the local similarity of CTC were taken into account in the evaluation function.Result shows that the performance of TC identification measured by accuracy is increased by 5.72 percent.
