AgentMap: Joint Equivalence and Subsumption Discovery for Ontology Matching
Yiping Song, Jiaoyan Chen, Renate Schmidt +2
The paper introduces Hybrid Ontology Matching (HOM), a task that simultaneously discovers equivalence and subsumption relations between ontologies, and presents AgentMap, a multi‑a…
NeurOWL: An LLM-Based Neural-symbolic Framework for Incomplete OWL Ontology Reasoning
Hui Yang, Jiaoyan Chen, Yiping Song +2
OWL ontologies provide a formal knowledge representation framework that enables semantic reasoning, and have been widely adopted across domains such as healthcare and bioinformatic…
Hierarchical Retrieval with Out-Of-Vocabulary Queries: A Case Study on SNOMED CT
Jonathon Dilworth, Hui Yang, Jiaoyan Chen +2
SNOMED CT is a biomedical ontology with a hierarchical representation, modelling terminological concepts at a large scale. Knowledge retrieval in SNOMED CT is critical for its appl…
RegD: Hierarchical Embeddings via Dissimilarity between Arbitrary Euclidean Regions
Hui Yang, Jiaoyan Chen
Hierarchical data is common in many domains like life sciences and e-commerce, and its embeddings often play a critical role. While hyperbolic embeddings offer a theoretically grou…
Large Language Model for OWL Proofs
Hui Yang, Jiaoyan Chen, Uli Sattler
The ability of Large Language Models (LLMs) to perform reasoning tasks such as deduction has been widely investigated in recent years. Yet, their capacity to generate proofs-faithf…
Unbiased Platform-Level Causal Estimation for Search Systems: A Competitive Isolation PSM-DID Framework
Ying Song, Yijing Wang, Hui Yang +12
Evaluating platform-level interventions in search-based two-sided marketplaces is fundamentally challenged by systemic effects such as spillovers and network interference. While wi…
