No Contextual Information
Contextual Information
Relational Semantics
Background Knowledge

Systems in this category generate representations for an entity using only its own descriptive information, such as labels and comments, while disregarding data from other entities in the ontology graph (e.g., parent or child classes).

70% Of surveyed systems employ pre-trained embedding models, adapting to domain semantics for matching tasks.

Typical Embedding-Based Matching Pipeline

Ontology Reading
Encoding (Text & Graph Embeddings)
Matching (Similarity & Filtering)
Rendering (Export Alignments)
Strategy Benefits Limitations
Lexical/Semantic Embeddings
  • Captures semantic info from labels/descriptions
  • Emphasizes language understanding
  • Often overlooks ontology structure
  • Struggles with polysemy without context
Graph-Based Embeddings
  • Represents ontologies as graphs
  • Captures hierarchical/relational patterns
  • May struggle with sparse or inconsistent graphs
  • Can produce erroneous similarities based solely on proximity
Hybrid Approaches
  • Combines lexical and structural features
  • Leverages strengths of both methods
  • Can be more complex and computationally demanding
  • Requires careful integration to avoid noise

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.

50% Of surveyed systems leverage contextual information to generate entity embeddings, showing a growing trend.

Contextual Embedding Generation Flow

Extract Entity & Neighboring Text
Enrich Text (e.g., Parent/Child Labels)
Encode with Transformer/Sentence Encoder
Aggregate (Attention/Pooling)
Compute Similarity & Align

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.

12% Only a small fraction of systems explicitly encode relational semantics, highlighting an underexplored area.

Relational Embedding Pipeline

Graph Construction (Ontology Triples)
Translate to Embedding Space (TransE/RotatE)
Encode Relationships (Property Vectors)
Aggregate with GNNs (R-GCN/GAT)
Infer Alignment with Semantic Constraints

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.

9% Only a limited number of systems integrate background knowledge, indicating an opportunity for richer embeddings.

Background Knowledge Integration Flow

Extract Ontology Entity Labels
Query External Sources (Wikipedia/WordNet)
Enrich Entity Descriptions
Generate Multi-View Embeddings
Compute Similarity & Alignment

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.
