To solve this problem, this study introduces a hybrid ontology matching method that integrates a Recurrent Neural Network (RNN) with syntax-based analysis. The method first extracts representative entities by leveraging in-degree and out-degree information from ontological tree structures, which reduces training noise and improves model generalization. Next, a matching framework combining RNN and N-gram is designed: the RNN captures medium-distance dependencies and complex sequential patterns, supporting the dynamic optimization of embedding parameters and semantic feature extraction; the N-gram module further captures local information and relationships between adjacent characters, improving the coverage of matched entities. The experiments were conducted on the OAEI benchmark dataset, where the proposed method was compared with representative baseline methods from OAEI as well as a Transformer-based method. The results demonstrate that the proposed method achieved an 18.18% improvement in F-measure over the best-performing baseline. This improvement was statistically significant, as validated by the Friedman and Holm tests. Moreover, the proposed method achieves the shortest runtime among all the compared methods. Compared to other RNN-based hybrid frameworks that adopt classical structure-based and semantics-based similarity measures, the proposed method further improved the F-measure by 18.46%. Furthermore, a comparison of time and space complexity with the standalone RNN model and its variants demonstrated that the proposed method achieved high performance while maintaining favorable computational efficiency. These findings confirm the effectiveness and efficiency of the method in addressing ontology heterogeneity in complex IoE environments.<\/jats:p>","DOI":"10.3390\/bdcc9080208","type":"journal-article","created":{"date-parts":[[2025,8,14]],"date-time":"2025-08-14T14:51:46Z","timestamp":1755183106000},"page":"208","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ontology Matching Method Based on Deep Learning and Syntax"],"prefix":"10.3390","volume":"9","author":[{"given":"Jiawei","family":"Lu","sequence":"first","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Lanzhou University of Technology, Lanzhou 730050, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5472-9401","authenticated-orcid":false,"given":"Changfeng","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Lanzhou University of Technology, Lanzhou 730050, China"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"63839","DOI":"10.1109\/ACCESS.2024.3390939","article-title":"Energy efficient hybrid evolutionary algorithm for Internet of Everything (IoE)-enabled 6G","volume":"12","author":"Singh","year":"2024","journal-title":"IEEE Access"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1815","DOI":"10.1007\/s11277-024-11577-3","article-title":"A review on cyber-twin in sixth generation wireless networks: Architecture, research challenges & issues","volume":"138","author":"Nivetha","year":"2024","journal-title":"Wirel.
