TermViewer is a web application for collaborative annotation and quality assessment of clinical notes processed by Natural Language Processing (NLP) algorithms, improving Human Phenotype Ontology (HPO) term accuracy.
Area of Science:
- Biomedical Informatics
- Computational Biology
- Clinical Data Science
Background:
- Electronic Health Records (EHRs) contain valuable clinical phenotype data.
- Natural Language Processing (NLP) algorithms can annotate Human Phenotype Ontology (HPO) terms from clinical notes.
- Existing NLP tools may produce erroneous annotations, necessitating manual review.
Purpose of the Study:
- To develop TermViewer, a web application for multi-party collaborative annotation and quality assessment of NLP-processed clinical notes.
- To facilitate the classification of high-quality notes and correction of inaccurate HPO term tagging.
- To enable collaborative manual review of computationally generated HPO annotations.
Main Methods:
- Developed TermViewer, a web application for collaborative annotation of clinical notes.
- Integrated MetaMap and cTAKES, two prominent NLP tools, to identify agreement and disagreement in HPO term tagging.
- Enabled users to view clinical notes with highlighted HPO terms for review and correction.
Main Results:
- TermViewer allows efficient, multi-party review and correction of HPO annotations from clinical notes.
- The application highlights discrepancies between MetaMap and cTAKES, aiding expert review.
- TermViewer supports the creation of high-quality, curated HPO datasets from clinical text.
Conclusions:
- TermViewer enhances the accuracy and reliability of HPO term extraction from clinical notes.
- The tool can be used independently or integrated into machine learning pipelines.
- Facilitates the use of clinical phenotype data for disease research and understanding.
