This paper introduces an intelligent legal consulting system that integrates three key components: the Legal-Onto knowledge representation model, the VietnamLegalText-SBERT embedding model, and a ReAct-based multi-agent framework. Legal-Onto organizes legal knowledge into semantic graphs of legal concepts, capturing internal relationships, definitions, and key attributes from legal texts. Each node in the knowledge graph is embedded using VietnamLegalText-SBERT\u2014a BERT-based model fine-tuned on Vietnamese legal corpora\u2014and stored in Elasticsearch to enable efficient vector-based retrieval. A multi-agent architecture facilitates step-by-step reasoning, query decomposition, document retrieval, legal interpretation, and output validation. The system is evaluated on real-world legal queries collected from public sources, showing superior performance over a general-purpose GPT-4o baseline in terms of answer accuracy, citation correctness, and contextual relevance. The results demonstrate that combining domain-specific semantic modeling with reasoning agents yields interpretable, reliable, and context-aware legal support, paving the way for broader public access to legal guidance in Vietnam.<\/jats:p>","DOI":"10.3233\/faia250544","type":"book-chapter","created":{"date-parts":[[2025,9,16]],"date-time":"2025-09-16T13:19:55Z","timestamp":1758028795000},"source":"Crossref","is-referenced-by-count":0,"title":["Integrating Legal BERT-Based Embedding and ReAct Multi-Agent for an Intelligent Consulting System"],"prefix":"10.3233","author":[{"given":"Tho H.","family":"Nguyen","sequence":"first","affiliation":[{"name":"University of Information Technology, Ho Chi Minh City, Vietnam"},{"name":"Vietnam National University, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hung Q.","family":"Ngo","sequence":"additional","affiliation":[{"name":"University of Information Technology, Ho Chi Minh City, Vietnam"},{"name":"Vietnam National University, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vuong T.","family":"Pham","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics and Computer Science, University of Science, Ho Chi Minh City, Vietnam"},{"name":"Vietnam National University, Ho Chi Minh City, Vietnam"},{"name":"Sai Gon University, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dung A.","family":"Tran","sequence":"additional","affiliation":[{"name":"University of Information Technology, Ho Chi Minh City, Vietnam"},{"name":"Vietnam National University, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anh T.","family":"Huynh","sequence":"additional","affiliation":[{"name":"University of Information Technology, Ho Chi Minh City, Vietnam"},{"name":"Vietnam National University, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hien D.","family":"Nguyen","sequence":"additional","affiliation":[{"name":"University of Information Technology, Ho Chi Minh City, Vietnam"},{"name":"Vietnam National University, Ho Chi Minh City, Vietnam"},{"name":"Computer Science Department, New Mexico State University, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","New Trends in Intelligent Software Methodologies, Tools and Techniques"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA250544","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,9,16]],"date-time":"2025-09-16T13:19:55Z","timestamp":1758028795000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA250544"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,9,16]]},"ISBN":["9781643686196"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia250544","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,9,16]]}}}
