An LLM-SPARQL Hybrid Framework for Named Entity Linking and Disambiguation to Wikidata
摘要
This research tackles the complex issue of Named Entity Disambiguation (NED) by harnessing the power of Large Language Models (LLMs), such as Generative Pre-trained Transformers (GPTs), and integrating these with structured information from knowledge graphs like Wikidata. The overarching goal is to markedly enhance NED accuracy through a synergistic approach that combines the predictive prowess of advanced LLMs with the detailed semantic repositories of KGs. Our key innovation is the formulation of a novel methodology that employs SPARQL queries to methodically retrieve potential Uniform Resource Identifiers (URIs) from Wikidata. These URIs serve as candidate references for named entities. We then apply cutting-edge generative AI techniques to accurately match each entity’s mention within texts to the most contextually relevant URI. This refined approach allows for a more sophisticated, context-aware resolution of entity references. We conducted extensive experiments to evaluate our method, which indicates a substantial achievement in performance, as evidenced by precision, recall, and F-measure. Impressively, our model achieves an F-measure of 96% on the Wikidata-Disamb dataset, a meticulously curated benchmark specifically developed for robust, scalable evaluation of NED performance leveraging Wikidata entries.
