Named Entity Recognition (NER) is essential for extracting and classifying specialized domain terms from textual data. Schemas provide structured frameworks by defining relevant entity classes and relationships, enabling computer systems to process discipline-specific terminology accurately. This study introduces the Schema for Mineral Systems (SMS), developed to evaluate NER accuracy in geoscientific texts on mineral systems, with nine geological and five general entity classes. SMS was created through domain characterization, word disambiguation, taxonomy development, and expert input to address the complexity of geological terminology. Domain-specific dictionaries and schema-linked annotations facilitated the identification of unique terms in mineral systems, while expert validation highlighted the importance of iterative verification to improve NER model performance. Applied to corpora on iron and lithium deposits in Western Australia, SMS use demonstrates the challenges of context-specific schemas in enhancing specialized knowledge extraction and accurate entity recognition in complex domains.
