Ontology-Guided Neuro-Symbolic Inference: Grounding Language Models with Mathematical Domain Knowledge

arXiv:2602.17826v1 Announce Type: new Abstract: Language models exhibit fundamental limitations -- hallucination, brittleness, and lack of formal grounding -- that are particularly problematic in high-stakes specialist fields requiring verifiable reasoning. I investigate whether formal domain ontologies can enhance language model reliability through retrieval-augmented generation. Using mathematics as proof of concept, I implement a neuro-symbolic pipeline leveraging the OpenMath ontology with hybrid retrieval and cross-encoder reranking to inject relevant definitions into model prompts. Evaluation on the MATH benchmark with three open-source models reveals that ontology-guided context improves performance when retrieval quality is high, but irrelevant context actively degrades it -- highlighting both the promise and challenges of neuro-symbolic approaches.

Executive Summary

This article explores the potential of using formal domain ontologies to enhance the reliability of language models. By leveraging the OpenMath ontology and a neuro-symbolic pipeline, the author demonstrates improved performance on the MATH benchmark when retrieval quality is high. However, the study also reveals that irrelevant context can degrade performance. These findings highlight the promise and challenges of neuro-symbolic approaches and suggest that the effective application of domain ontologies is crucial to unlocking their potential. The study has significant implications for the development of language models in high-stakes specialist fields and underscores the need for further research into the integration of formal domain knowledge and machine learning.

Key Points

  • The use of formal domain ontologies can enhance the reliability of language models.
  • A neuro-symbolic pipeline leveraging the OpenMath ontology can improve performance on the MATH benchmark when retrieval quality is high.

Merits

Strength in Conceptual Framework

The article provides a clear and well-defined conceptual framework for integrating formal domain ontologies with language models, which is a significant contribution to the field.

Methodological Rigor

The study demonstrates methodological rigor through the use of a well-established benchmark and the evaluation of multiple open-source models.

Demerits

Limitation in Generalizability

The study's focus on mathematics as a proof of concept may limit the generalizability of the findings to other domains.

Overreliance on Retrieval Quality

The article highlights the importance of retrieval quality, but does not explore potential solutions for when retrieval quality is low.

Expert Commentary

The article's findings have significant implications for the development of language models in high-stakes specialist fields. While the use of formal domain ontologies shows promise, the challenges of neuro-symbolic approaches must be carefully considered. Future research should focus on addressing the limitations of the study, including the potential for irrelevant context to degrade performance and the need for solutions to improve retrieval quality when it is low. Additionally, the integration of formal domain knowledge and machine learning has significant implications for the development of AI systems in various industries and domains, and policymakers should take note of these developments.

Recommendations

  • Future research should focus on developing more robust methods for integrating formal domain ontologies with language models.
  • Developers should prioritize the careful evaluation and selection of retrieval algorithms to improve the quality of retrieved information.
