The Research Of Engineering Construction Standards Based On Data Mining

Along with related standards of domestic construction process increasingly consummate,the standardization of construction process is significant.Recently,the quantity of engineering construction standards is increasing,how to help requesters select standards from increasing engineering standards accurately and quickly,have already become a focus in academic circles.Studies show that,pretreatment engineering construction standard lack of advanced technology and methods,the path of using engineering construction standards is long and inefficient which is the root cause,therefore,it is need to research based on data mining in engineering construction standards of construction process.Based on improving the query and efficiency of engineering construction standard as the goal-oriented,exploring the data mining that play a role in engineering construction standard of construction process under the new situation.Firstly,the background of state-related policy,engineering construction standard,data mining.Comprehensivly analysis the engineering construction standard data mining research between domestic and abroad,This paper puts forward the research content,the logical framework and the innovation of the article.Secondly,it introduces the construction process and the construction engineering standard,define their concepts,analysizing the natures of engineering construction standard,and the relationship between engineering construction standard and construction process.Based on the theory of data mining of engineering construction standard in construction process,study the data mining technology introducing engineering construction standards.This paper introduces the data mining method and the text mining for the engineering construction standard,and constructs the standard classification model of engineering construction by using the data mining method,then classifies it in a targeted way to realize the agile selection of the engineering construction standard.Finally,faced with construction process of Changchun,select the corresponding evaluation method that evaluate the standard implementation of the construction process through the system,by calculating the comprehensive evaluation result,summarize and give the rationalization suggestion according to the calculation result.Since the construction standards are generally expressed by text,so bring data mining in the engineering construction standards,the primary problem is to transform engineering construction standards expressed by natural language into intermediate language,which can be able to operate by a computer.The use of Chinese word segmentation,feature extraction,standardized methods,making pre-treatment on the studied engineering construction standards,using the improved KNN algorithm based on association rules,to build engineering construction standards classification system,evaluate the system by accuracy and error rate.Combined with the subproject,analysis those who demand standards of the key points,to improve oriented implementation efficiency,which are both the focus and the innovation of this study.This study includes: the engineering construction standards of the construction process,data mining technology provide a technical support,define construction and engineering construction standards,and analysis the relationship between construction and engineering construction standards Research on engineering construction standards based on text data mining,establish text classification system of engineering construction standards,with high accuracy and high efficiency;making full use of the keyword part of engineering construction standard,improve the recognition rate of key points,that in engineering construction standards.Studies e shows that research on engineering construction standards by data mining is significative in reality.
