Using off-the-shelf LLMs to query enterprise data by progressively revealing ontologies (2410.09244v1)

Abstract: Ontologies are known to improve the accuracy of LLMs when translating natural language queries into a formal query language like SQL or SPARQL. There are two ways to leverage ontologies when working with LLMs. One is to fine-tune the model, i.e., to enhance it with specific domain knowledge. Another is the zero-shot prompting approach, where the ontology is provided as part of the input question. Unfortunately, modern enterprises typically have ontologies that are too large to fit in a prompt due to LLM's token size limitations. We present a solution that incrementally reveals "just enough" of an ontology that is needed to answer a given question.
