摘要CMS 0094022“数据库中的知识发现和数据挖掘作为支持现代建筑管理研究和教育进步的新工具”PI：Lucio Soibelman，伊利诺伊大学厄巴纳-香槟分校建筑行业正在看到其生成和收集数据的能力的爆炸性增长。科学数据收集的进步、几乎所有商业产品的条形码的引入、新的传感器技术、无线计算和新的激光扫描技术，产生了大量的数据。这些进步加上数据存储技术的进步，如更快、更高容量和更便宜的存储设备、更好的数据库管理系统和数据仓库技术，增加了计算机化建筑数据的可用性。然而，在大多数情况下，这些数据仅用于通信目的，并存储在文件或数据库中而不进行分析。本计画将应用资料探勘与知识发现于资料库中，以研究此日益增加的可用资料量。数据库中的知识发现和数据挖掘是将来自机器学习、人工智能、模式识别、统计学、数据库和可视化的技术联合收割机以自动地从大型数据库中提取概念、概念相互关系和感兴趣的模式的技术。该职业计划的目标是：1）生成改进的方法，从大型建筑数据库中获取新的知识，开发模型构建模板和向导，以指导新手建筑知识模型构建者根据自己的数据创建模型的过程; 2）改善从业人员和学生对过去建筑管理经验和知识的访问;（3）利用本研究中产生的知识开发教育模拟策略类游戏，运用主动学习技术提高各级学生的教育水平; 4）教授土木与环境工程研究生通过数据挖掘的应用和发展产生知识的过程，机器学习和人工智能工具。鉴于建筑业在美国经济中的重要性，以及由于项目延误、不切实际的预算以及既不满足质量要求也不满足性能预期的项目而导致的大量资金浪费在诉讼中，因此迫切需要改进的管理工具。这项研究有望产生有价值的管理工具，以改善项目规划和控制，如果应用于大型基础设施项目，可能会导致全国范围内的大量成本节约。这些研究成果可以推广到施工管理的各个子领域

ABSTRACT CMS0094022 "Knowledge Discovery in Databases and Data Mining as New tools to Support Research and Educational Advances in Modern Construction Management " PI: Lucio Soibelman, University of Illinois at Urbana-ChampaignThe construction industry is seeing an explosive growth in its capabilities to both generate and collect data. Advances in scientific data collection, the introduction of bar codes for almost all-commercial products, new sensor technologies, wireless computing, and new laser scanning technologies, have generated a flood of data. These advances coupled with advances in data storage technology, such as faster, higher capacity, and cheaper storage devices, better database management systems, and data warehousing technology, have increased the availability of computerized construction data. However, in most cases, these data are used only for communication purposes and stored in a file or a database without being analyzed. This project intends to study this increasing amount of available data by applying data mining and knowledge discovery in databases. Knowledge discovery in databases and data mining are technologies that combine techniques from machine learning, artificial intelligence, pattern recognition, statistics, databases and visualization to automatically extract concepts, concepts interrelationships, and patterns of interest from large databases. The objectives of this CAREER program are to: 1) Generate improved methods to obtain novel knowledge from large construction databases developing model-building templates and wizards to guide novice construction knowledge model builders through the process of creating models based on their own data; 2) Improve access to past construction management experience and knowledge by practitioners and students; 3) Use active learning techniques to improve education of students at all levels by developing an educational simulation game with the knowledge generated during this research; and 4) Teach civil and environmental engineering graduate students the process of knowledge generation through the application and development of data mining, machine learning and artificial intelligence tools.Given the importance of the construction industry in the U.S economy and the large amount of money wasted in litigation due to project delays, impractical budgets, and projects that neither satisfy quality requirements nor meet performance expectations, improved management tools are critically needed. This research promises to result in valuable management tools for improving project planning and control, which, if applied to large-scale infrastructure projects, may result in substantial cost savings nationwide. These research benefits can be extended to all sub-fields of construction management
