Abstract: An automatic annotation method for professional literature was proposed. Through comparing with other storage formats and literary styles, two features of professional literature were summarized, and then three assumptions were proposed. To improve annotation efficiency, based on topology structure, the domain ontology was partitioned into segments which were self-consistent, then the most related segments were located with the keywords extracted from document, finally the document with located segments was annotated and the annotation scope was expanded according to the correspondence between grammatical structure and semantic structure. The experimental results show that the proposed method can improve annotation efficiency, annotation quantity and annotation accuracy.

Key words: professional literature, semantic annotation, ontology partition, semantic context, syntax context

摘要： 提出了一种标注方法实现语义网中无结构专业文档的自动标注。通过分析给出专业文档的两方面特征，并提出了三个假设。为提高标注效率，基于结构对本体进行分割，将本体划分成具有较高语义独立性的片断；然后利用从专业文档中抽取的关键词定位本体片断；最后，使用选中的片断，利用语法结构和三元组的对应性对文档进行标注。实验结果表明，所提出方法在标注效率、标注数量和准确性三个方面都有所提高。
