Teodora Cristiana Nemțoc, PhD student in Business Informatics supervised by Prof.dr. Gheorghe Cosmin Silaghi within the Doctoral School of Economics and Business Administration, participated in the ER 2025 – 44th International Conference on Conceptual Modeling, held in Poitiers, France, between October 20–23, 2025. The Conceptual Modelling conference is an established international venue in computer science, ranked in category A by the The Computing Research and Education Association of Australasia (CORE – https://portal.core.edu.au/conf-ranks/971/).
The presented paper (published in the Lecture Notes in Computer Science series by Springer and available at https://link.springer.com/chapter/10.1007/978-3-032-08623-5_16) explores the synergy between Large Language Models and Knowledge Graphs, proposing a custom GraphRAG framework designed to handle natural language queries in a manner analogous to a specialized environment required for SPARQL-based queries. The experimental setup serves as a comprehensive catalog that highlights the strengths and limitations of the system with respect to key parameters such as model type, query pattern, and integrated prompting strategy, illustrating how GraphRAG can bridge the gap between the ease of formulating natural language queries and the rigor and accuracy inherent in deterministic SPARQL queries.
