    • An apparatus and method for efficiently constructing learning data required in statistical methodology used in information retrieval, information extraction, translation, natural language processing, etc. are provided. The method includes the steps of: generating learning models by performing machine learning with respect to learning data; attaching tags to a raw corpus automatically by using the generated learning models to thereby generate learning data candidates; calculating confidence scores of the generated learning data candidates, and then selecting a learning data candidate using the confidence scores; and allowing a user to correct an error in the selected learning data candidate through an interface and adding the error-corrected learning data candidate to the learning data, thereby adding new learning models incrementally.
    • 提供了一种用于有效地构建用于信息检索,信息提取,翻译,自然语言处理等的统计方法中所需的学习数据的装置和方法。 该方法包括以下步骤:通过相对于学习数据执行机器学习来产生学习模型; 通过使用生成的学习模型自动附加标签到原始语料库,从而生成学习数据候选; 计算生成的学习数据候选的置信度分数,然后使用置信分数选择学习数据候选; 并且允许用户通过接口校正所选择的学习数据候选中的错误,并将纠错学习数据候选者添加到学习数据中,从而逐渐增加新的学习模型。

    • The present invention relates to a semi-automatic construction method for knowledge base of an encyclopedia question answering system, in which concept-oriented systematic templates are designed and important fact information related to entries is automatically extracted from summary information and body of the encyclopedia to semi-automatically construct the knowledge base of the encyclopedia question answering system. A semi-automatic construction method for knowledge base of an encyclopedia question answering system of the present invention comprises the steps of: (a) designing structure of the knowledge base with a plurality of templates for each entry and a plurality attributes related to each of the templates; (b) extracting structured information including the entry, an attribute name and attribute values from summary information of the encyclopedia; (c) extracting unstructured information including an attribute name and attribute values of the entry from a body of the encyclopedia; and (d) storing the structured information and the unstructured information in corresponding template and attribute of the knowledge base according to the entry.
    • 本发明涉及一种百科全书问答系统的知识库的半自动构建方法,其中设计了面向概念的系统模板,并且将从条目的重要事实信息自动地从百科全书的摘要信息提取为半 - 自动构建百科全书问答系统的知识库。 本发明的百科全书问答系统的知识库的半自动构建方法包括以下步骤:(a)利用每个条目的多个模板来设计知识库的结构,以及与每个条目相关的多个属性 模板; (b)从百科全书的摘要信息中提取包括条目,属性名称和属性值的结构化信息; (c)从百科全书的主体中提取非结构化信息,包括该条目的属性名称和属性值; 以及(d)根据该条目将结构化信息和非结构化信息存储在知识库的相应模板和属性中。
