Addressing the Core Bottleneck in BEL
Biomedical Entity Linking (BEL) is crucial for transforming unstructured clinical text into structured concepts, but its progress is hampered by the extreme scarcity of high-quality, expert-annotated training data. This section provides an overview of how SynCABEL directly tackles this challenge by generating context-rich synthetic training examples.
Generative AI for Enhanced BEL Training
SynCABEL employs a novel framework combining large language models for synthetic data generation, adaptive concept representation, and guided inference. This allows the creation of diverse, context-aware training instances for all candidate concepts in a knowledge base, providing broad supervision without manual annotation.
State-of-the-Art Performance and Efficiency
Our experiments demonstrate that SynCABEL, when integrated with decoder-only models, establishes new state-of-the-art results across major multilingual benchmarks (English, French, Spanish). Crucially, it achieves this with significantly less human-annotated data, proving its efficiency and real-world applicability.
Bridging the Annotation Gap and Beyond
While SynCABEL significantly mitigates annotation scarcity, it also reveals avenues for further improvement, especially for entirely unseen concepts. Future work will focus on extending generation contexts, multilingual expansion, and refining training strategies to enhance data quality and reduce computational costs.

Boosting Generalization for Unseen Concepts
A key challenge in BEL is the inability of models trained solely on human-annotated data to generalize effectively to concepts not present in the training set.
Challenge: Traditional models show poor performance on unseen concepts (e.g., 20.8% Recall@1 on SPACCC).
Solution: SynCABEL augments training data with synthetic examples for all KB concepts, including those not present in human annotations.
Result: Performance on unseen concepts drastically improves (e.g., up to 30.2% on SPACCC, an increase of 9.4 percentage points on QUAERO-EMEA), demonstrating enhanced generalization and broader KB coverage.
