Case Study: Cross-Lingual Ontology Matching
In a multilingual domain, Word2Vec and fastText embeddings are used to generate representations for cross-lingual ontology matching. An intermediate vector based on cross-similarity between words in entity labels addresses out-of-vocabulary (OOV) terms. This approach enhances generalization and performance across diverse linguistic contexts, demonstrating the power of embedding strategies beyond monolingual applications.
Systems that exploit contextual information derived from neighboring entities (e.g., class hierarchy, associated properties, instances) to compute entity similarity, enriching representations by aggregating features from the surroundings.

Of surveyed systems leverage contextual information to generate entity embeddings, showing a growing trend.

Case Study: Enhancing Biomedical Ontology Alignment with BERTMap
BERTMap leverages BERT-based contextual embeddings to align biomedical ontologies, addressing issues like polysemy and lack of explicit definitions. By fine-tuning BERT on ontology-specific data and using a binary classifier to predict alignment probability, BERTMap significantly improves F-measure scores in challenging biomedical domains. This demonstrates the critical role of contextual understanding in complex ontology matching scenarios.
Systems that explicitly encode the type of properties an entity has with its neighbors when generating embeddings, distinguishing between different kinds of properties (e.g., inheritance, disjointness) to reflect semantic constraints.

Only a small fraction of systems explicitly encode relational semantics, highlighting an underexplored area.

Case Study: GNNs for Precise Alignment
Graph Neural Networks (GNNs), particularly R-GCNs, explicitly encode relationship types during aggregation, providing richer contextual depth. For example, a system using GNNs for biomedical ontologies successfully distinguished between sameAs and broadMatch relations, achieving higher precision by reflecting semantic constraints that simple proximity measures would miss. This is crucial for high-stakes domains.
Systems that enrich entity embeddings by incorporating information from sources external to the input ontologies, such as Wikipedia or WordNet, providing supplementary context beyond explicitly stated ontology data.

Only a limited number of systems integrate background knowledge, indicating an opportunity for richer embeddings.

Case Study: ALOD2Vec with External Vector Datasets
ALOD2Vec improves ontology matching by querying external RDF2Vec-based vector datasets using entity lexical information. This approach is particularly effective for entities lacking rich descriptive text within the ontology itself. By leveraging the vast knowledge encoded in external sources, ALOD2Vec achieves a higher F-measure in tracks like KnowledgeGraph and LargeBio, demonstrating the power of external knowledge for robust and generalizable embeddings.
