为提高特定领域作战文书关键信息抽取的召回率和精确率,提出一种作战文书关键信息的抽取方法.分析作战文书的记述特征,构建领域本体以明确抽取内容,而后利用领域词典标记文书文本,并采用信息抽取模式抽取关键信息.实验结果表明,该方法在实际项目中可以很好地完成抽取任务,能促进C<'4>I系统建设和作战模拟的发展.%To improve the recall rate and precision rate of key information extraction from operational document, an approach is presented. First, it analyzes the character of operational document and builds domain ontology to ascertain what should be extracted. Then, it tags the document using domain lexicon. At last, it extracts key information employing extraction pattern. The experiment results show that the approach can accelerate the development of C4I and can be applied in practice.
