Apache cTAKES
open-in-new
<p>Apache cTAKES: clinical Text Analysis and Knowledge Extraction System is an open-source <a href="/facts/Natural_Language_Processing/1hjMKsSN">Natural Language Processing</a> (NLP) system that extracts clinical information from <a href="/facts/Electronic_health_record/0my0rktq">electronic health record</a> <a href="/facts/Unstructured_data/HrYRs7wq">unstructured text</a>. It processes clinical notes, identifying types of clinical named entities — drugs, diseases/disorders, signs/symptoms, anatomical sites and procedures. Each named entity has attributes for the text span, the ontology mapping code, context (family history of, current, unrelated to patient), and negated/not negated. </p><p>cTAKES was built using the <a href="/facts/UIMA/yPYDpQPS">UIMA Unstructured Information Management Architecture framework</a> and <a href="/facts/OpenNLP/dDUPnuzz">OpenNLP</a> natural language processing toolkit. </p>
