Ontology is shaping up to be the buzzword of 2026 because they are offering what #LLMs are lacking: formal grounding
LLMs offer creativity but need logical grounding. Ontologies provide this formal structure, anchoring meaning and unifying diverse data sources into a single semantic layer. They are essential for achieving precision and are one of the most reliable defense mechanisms against

Semantic Bridges Between First Order c-Representations and Cost-Based Semantics: An Initial Perspective
Weighted-knowledge bases and cost-based semantics represent a recent formalism introduced by Bienvenu et al. for Ontology Mediated Data Querying in the case where a given knowledge base is inconsistent. This is done by adding a weight to each statement in the knowledge base (KB), and then giving each DL interpretation a cost based on how often it breaks rules in the KB. In this paper we compare this approach with c-representations, a form of non-monotonic reasoning originally introduced by Kern…
