Risk Prediction Pattern Matching Method of Construction Project Management System in Big Data Era

In view of the influence of the scale of pattern information set on the pattern matching of risk prediction, aiming at improving the performance of pattern matching of risk prediction, this paper puts forward the method of pattern matching of risk prediction of construction project management system in the era of big data. In the era of big data, the central idea of risk prediction pattern matching algorithm is analyzed. Based on the description of risk prediction pattern matching algorithm, the specific implementation steps of risk prediction pattern matching algorithm are designed, the design of risk prediction pattern matching algorithm is completed, and the risk prediction pattern matching process of construction project management system is combined to achieve the risk prediction pattern matching. The experimental results show that, under different experimental platforms, compared with other risk prediction pattern matching methods, the accuracy of risk prediction pattern matching method of construction project management system in the era of big data is higher.
