Research on knowledge database of construction scheme

Construction knowledge is divided into book knowledge,real projects and expert experience with an object-oriented method to facilitate construction knowledge representation.Knowledge obtaining mission in a knowledge database is divided into three obtaining missions in relatively independent knowledge classes in terms of knowledge class semantics and analytical hierarchy.The three levels of construction knowledge updating are reflected into the three levels of knowledge growth mechanism(knowledge item→knowledge class→structure construction system knowledge).A knowledge reasoning mechanism with dynamic link knowledge objects was put forward.The mechanism improves the operational efficiency of large-scale knowledge system.
