中文摘要：

为促进项目参与方的合作和交流从而使项目更优质高效的完成，研究了结合IFC标准进行建设项目文档分类的方法。在对建设项目管理的特点进行深入分析的基础上，文章提出了将项目生命期中产生的大量的半结构化或非结构化的中文文本按照国际通用的IFC标准进行分类的方法，从而改进了文本的管理与利用效果。通过空间向量模型来表示中文文本，并采用夹角余弦的方法与国际通用的IFC标准中的实体进行相似度计算，最终实现中文文本的标准化分类，并通过案例分析验证了该方法的可行性。最后对本文提出的算法进行了评价，并提出了下一步的研究方向。

英文摘要：

In order to improve the usage of the construction documents, facilitate the communication and cooperation among the participants to enhance project management, this paper presents a method of classifying the semi-structured and unstructured Chinese documents, which are produced during the project lifecycle, combined with the commonly used IFC standard based on the analysis of the characteristics of construction project management. This paper conducts a similarity computing between the entities of IFC standard and the Chinese documents by means of Space Vector Model and Cosine similarity algorithm in order to realize the standardized classification of the Chinese documents. Case study proves the effectiveness of the proposed method.
