💡 What: Added
@functools.lru_cacheto_compiled_context_lexicon(inopenmed/openmed/clinical/context.py) and_cue_pattern(inopenmed/openmed/clinical/experiencer.py).🎯 Why: These functions were repeatedly recompiling regular expressions and re-generating lexicons dynamically during text span evaluation, creating a measurable performance bottleneck in the NLP pipeline. By memoizing the outputs based on their hashable inputs (string language codes or tuples of cue strings), we can reuse the compiled regex objects.
📊 Impact: Reduces time spent on deterministic lexicon generation and regex compilation to nearly 0 after the first run. The profiling benchmark indicated execution times for operations like
resolve_negationdropping by over 50%.🔬 Measurement: Verifiable by checking the time taken to run
