中文摘要： 对项目知识情境的深入理解可以提升项目知识学习与重用的效率和效果，促进企业/组织中的项目知识共享，提高项目管理水平。从项目数据中获取项目知识情境，并将其以恰当的方式展现出来，是学习、理解项目知识情境的前提。但是目前还缺乏在大量项目数据中进行项目知识情境提取和展现的有效方法。本课题将通过对大量项目数据的分析与挖掘，完成以下工作：1）探索大数据环境下项目知识情境提取的方法，通过对传统主题模型的改进，得到考虑项目工作数据信息和项目知识情境关系的新型主题模型；2）梳理、阐释项目情境与知识以及情境与情境之间的关系，探索能在大数据环境下清晰、完整、准确地表示项目知识情境内容及关系的项目知识地图的构建方法；3）根据上述方法设计项目知识情境提取与展现系统原型，实现项目知识情境的自动化提取与可视化展现。本课题的研究将为促进大数据环境下的项目知识学习与重用、提高项目知识管理信息化水平提供科学的理论方法与模型

英文摘要： Understanding the context of project knowledge in depth can help project members improve the efficiency and effectiveness of project knowledge learning and reuse, promote project knowledge sharing in enterprises or organizations, and raise the level of project management. Extracting project knowledge contexts from project data and representing them in an appropriate way are the key premise of learning and understanding these context information.However, it is lack of effective methods to extract project knowledge contexts from a huge number of project data and represent them at present. Through analyzing and mining a huge mass of project data, this research will achieve the following objectives: 1) to explore possible methods of extracting project knowledge contexts at the big data environment, through improving the traditional topic models, build a new topic models by analyzing project working data and the relationships among project knowledge contexts. 2）to systemize and explain the relationships among project knowledge and project knowledge contexts, and find a method of building a project knowledge map model which can show these relationships clearly, completely and correctly under the big data environment. 3）Based on the above methods, a system prototype of extracting and representing project knowledge contexts will be designed for making project knowledge contexts extracting automatically and representing realization. This research will provide scientific methods and models to promote project knowledge learning and reuse in organizations and enhance the organizations' informatization ability on project knowledge management at the age of big data.
