Article Synopsis
- Comparative effectiveness research (CER) requires high-quality data from diverse electronic health record (EHR) systems, and uniformity in this data is critical for accurate study outcomes.
- The CER Hub developed a quality assurance (QA) process using the 'emrAdapter' tool, which conducts quality checks on primary care encounter records and reports data issues for local fixes.
- After implementing the QA process across six health systems, data quality significantly improved over three iterations, addressing issues such as incomplete mapping of local EHR data to a standardized framework.
A fuzzy ontological knowledge document clustering methodology.
IEEE Trans Syst Man Cybern B Cybern
June 2009
This correspondence presents a novel hierarchical clustering approach for knowledge document self-organization, particularly for patent analysis. Current keyword-based methodologies for document content management tend to be inconsistent and ineffective when partial meanings of the technical content are used for cluster analysis. Thus, a new methodology to automatically interpret and cluster knowledge documents using an ontology schema is presented.
