Matching patients to suitable clinical trials is a pivotal but highly challenging process in modern medical research. It involves analyzing complex patient medical histories and mapping them against considerable levels of detail found in trial eligibility criteria. These criteria are complex, ambiguous, and heterogeneous, making the undertaking labor-intensive and prone to error, inefficient, and delaying the realization of critical research progress while many patients are kept waiting for experimental treatments. This is exacerbated by the requirement to scale across large collections of trials, especially in areas like oncology and rare diseases, where precision and efficiency are highly valued. Traditional methods
