magneto-schema-retriever-gdc

Model overview

This is a fine-tuned version of sentence-transformers/all-mpnet-base-v2 for schema matching tasks in the biomedical domain, specifically targeting the GDC (Genomic Data Commons) data standard. The model was fine-tuned using a self-supervised approach that leverages LLMs to generate diverse training data from the GDC target schema. The key innovation is combining LLM-based augmentation with structure-based augmentation: **1. LLM-Based Augmentation (`llm-aug`):** - For each anchor column in the GDC target schema, an LLM generates semantically equivalent but syntactically diverse variations - Captures syntactic heterogeneity common in real biomedical datasets - Example transformations: - `patient_id` → `subject_identifier`, `participant_number`, `patient_identifier` - `diagnosis_date` → `date_of_diagnosis`, `dx_date`, `diagnostic_date` - Creates diverse positive examples while preserving semantic meaning
