The present invention relates to a text mining application technique for efficient construction document management. The construction document management and visualization system developed using the text mining technology according to the present invention is applied to the development of a "UNI (User Needed Information) - Tacit" system prototype for a text mining application technique for efficient construction document management, Can improve the productivity of construction projects by enabling effective and efficient management of documents in the construction industry field and more specifically by automating much of the process of document management that has previously been done passively, It is possible to reduce the consumption and manage the mutually exclusively managed documents based on the keyword, thereby enhancing the efficiency of the business and facilitating the collaboration and improving the productivity. Also, the document management through the construction document management system utilizing the text mining technology according to the present invention can be applied not only to the construction industry but also to other industrial fields, thereby enabling effective and efficient management of complex and various types of documents.
