Abstract：To improve theaccuracyof chemical informationretrieval，acomprehensivesemantic similarityretrieval method was proposed.A comprehensive semantic similarity calculation model was constructed by combining string semantic similarity，node semantic distance similarity，and neighboring nodesimilarity.To determine the weightsof diffrent semantic similarities，a generalized regression neural network（GRNN）optimized bythebat algorithm was used to train and alocate weight values.The comprehensive semantic similarity formula was used to retrieve semanticsinthe fieldof chemical engineering.Theresults indicatethatthesemanticretrieval resultsofchemical information obtained bythe proposed method are close to the expert rating results，with an average Pearson corelation coefficient value ofO.94.Compared to the comparison method，the calculation results of this method are more similar to the expert rating results.
