From bc9366b054b62998d2b0b7070a0621cec072f282 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Wed, 29 Jul 2026 17:24:38 +0000 Subject: [PATCH] Memoize clinical lexicons and alias mappings to drastically improve document processing performance. This adds `@functools.lru_cache` to `_compiled_context_lexicon`, `_alias_lookups`, and `_aliases_for_language` in `openmed.clinical` as these deterministic lexicons were previously constructed and regex-compiled repeatedly per-document or per-span during text processing.
