| 摘 要： | 对利用关键动词(即语义关系动词)进行关系抽取的研究进行回顾,并对生物医学语义关系抽取的常用方法进行详细介绍。认为目前关系抽取研究中所利用的关键动词主要是人工选取的,涉及的主观因素较多,影响关键动词选取的客观性、准确性和全面性。因此,如何自动化地找到这些动词可能会成为今后关系挖掘的一项关键任务。

| Abstract: | The paper mainly reviews the semantic relation extraction studies used key verbs(i.e.semantic verb),and introduces the methods of biomedical semantic relations extraction.The key verbs used in the present researches are manually selected,so the verb selection method involves more subjective factors,and influences the objectivity,accuracy and comprehensiveness of key verbs selection.Therefore,how to find these verbs automatically may be a key task of relations mining. |
