Highlights
► We developed automated methods to derive a probabilistic syntacto-semantic grammar. ► The grammar was derived based on concepts in public biomedical terminologies. ► We evaluated the grammar on parsing noun phrases in clinical notes. ► The grammar achieved higher parsing accuracy than a semantic-null control. ► The methods appear helpful in semantic engineering of biomedical parsers.
