摘要

[目的] 抽取领域科技文献中句子级创新点。[方法] 面向文献中的句子，以领域词表和本体中的关系为基础构建识别规则，采用基于主题词重叠度的冗余度计算方法过滤创新点候选集。[结果] 选取肿瘤领域的数据集进行实验，抽取结果的准确率为89.42%，召回率为60.14%。[局限] 规则有待进一步完善，提高召回率。[结论] 利用领域词表和本体中的关系能有效地抽取科技文献中的句子级创新点。

Abstract：

[Objective] This article aims to extract innovation points of sentence-level from scientific research paper of specific domain. [Methods] The field thesaurus and Ontology are used in constructing rules to extract innovation points from sentences in research papers, and a redundancy computing method based on keyword-overlap computing is used to filter redundant innovation points. [Results] The experiment is undertaken on data set of Neoplasm and the result shows that the accuracy rate is 89.42% and the recall rate is 60.14%. [Limitations] The rules need to be further improved, and the recall rate needs to be improved. [Conclusions] Using field thesaurus and the relationships in Ontology is effective in extracting innovation points from scientific research paper.

Key words： Scientific research paper Linguistic feature Structured abstract Innovation point extraction Overlap computing
