    摘要:

    针对军用命名实体的识别难点,采用多模型结合的方法进行军事命名实体识别。在对军用文本信息进行 深入的研究和分析的基础上,根据其特点设计了一个基于双层模型的军事命名实体识别系统,并将军事命名实体分 为简单实体名和复杂实体名2 类:在底层采用CRFs 模型进行简单实体名识别,再采用SVM 与CRFs 结合判断命名 实体的左右边界,进行复杂命名实体的辅助识别,最后进行两层识别结果的合并。实验结果表明:该识别模型是一 种比较理想的方法。

    Abstract:

    In order to identify military named entities a multi-models method was proposed. After detailed research and analysis on military text efficient military named entity recognition system, which is based on a dual-layered model, is presented. The military named entity group is divided into two categories: simple name and complicated ones. First the simple named entity is recognized in the first layer with CRFs, the results are transferred to the second layer to support the recognition of complicated named entity. In the second layer, SVM was used to decide the right boundary of a complicated named entity and then CRFs model was used to tag the former boundary. Last the simple and complicated named entity recognition results are combined together. Experimental results show that the model is effective.
