The Power of Ontology-Based KRP
Ontology-based Knowledge Retrieval Practices (KRP) transform scattered engineering records into a coherent, semantically rich knowledge space, boosting both efficiency and accuracy. Unlike conventional keyword search, KRP exploits concept uniqueness, semantic relations, and logical reasoning to infer user intent and deliver precise, relevant answers. This approach is crucial for complex aircraft assembly, where traditional methods struggle with vast, interrelated knowledge types and semantic dependencies.
It creates a shared vocabulary for people and systems, enabling the system to interpret intent, disambiguate terms, and return context-aware answers, accelerating innovation and sustaining operational excellence.
Integrated Retrieval Mechanisms
The system orchestrates three retrieval modes: Ontology Based Semantic (OBS) for conceptual and attribute queries, Rule-Based Inference (RBI) for computable dimensioning and sequencing, and Case-Based Reasoning Instances (CBRI) for structural analogies and fine adjustments. This multi-strategy approach ensures that the most appropriate retrieval method is used based on the knowledge type requested, leading to highly accurate and context-aware results.
Each strategy plays a complementary role, addressing different facets of the complex tooling design process and ensuring comprehensive knowledge discovery.
Robust Evaluation & Outcomes
Evaluation across twenty decision-like tasks, graded tooling corpora (100–420 documents), and a domain-agnostic stress test demonstrated a mean task-level accuracy of 93.1%, with the hybrid OBS+RBI+CBRI configuration reaching 96.9% confidence. Document-level accuracy was 98–99% on tooling corpora. The system consistently outperformed traditional retrieval methods, showing significant gains in precision and recall for complex engineering queries.
These robust results validate the effectiveness of the KRP framework in delivering reliable, decision-ready guidance for aerospace manufacturing.
