The invention provides a material similarity analysis method based on a semantic library and a knowledge graph, and the method comprises the following steps: S1, judging whether the decisive attributes of two materials are similar or not, if any one of the decisive attributes is not similar, determining that the two materials are non-repeated-code materials, and otherwise, entering S2; s2, calculating the similarity of the field parts according to the non-decisive attribute weight and the distance of each field; s3, combining all knowledge graph paths and weight values to calculate the similarity of graph parts; and S4, adding the similarity of the field part and the similarity of the map part to obtain a final material similarity, and judging whether the two materials are high in similarity or not through the final material similarity. The material similarity analysis method provided by the invention optimizes the accuracy of a similarity algorithm. 本发明提供了一种基于语义库和知识图谱的物资相似性分析方法，包括以下步骤：S1：判断两个物资的决定性属性是否相似，若其中
