Abstract: In order to improve the accuracy and efficiency of the environmental protection evaluation results of building materials, a new environmental protection evaluation method of inorganic non-metallic building materials based on principal component analysis was proposed. Firstly, knowledge atlas and collaborative filtering algorithm are used to mine evaluation indicators. Then, the evaluation index system is constructed, and the judgment matrix is established to calculate and sort the weight of the evaluation index. Finally, the principal component analysis method is introduced to evaluate the environmental protection performance, and the original evaluation index is standardised to obtain the comprehensive score of the environmental protection performance of building materials, to realise the environmental protection performance evaluation. The experimental results show that the evaluation accuracy of the proposed method is high and the time consumption is short, indicating that the evaluation results are reliable.

Keywords: principal component analysis; standardised treatment; judgment matrix; knowledge map; collaborative filtering algorithm.
