Analyzing Patterns of Literature-Based Phenotyping Definitions for Text Mining Applications. In 2018 IEEE International Conference on Healthcare Informatics (ICHI) (pp. 374–376). https://doi.org/10.1109/ICHI.2018.00061https://hdl.handle.net/1805/18757Phenotyping definitions are widely used in observational studies that utilize population data from Electronic Health Records (EHRs). Biomedical text mining supports biomedical knowledge discovery. Therefore, we believe that mining phenotyping definitions from the literature can support EHR-based clinical research. However, information about these definitions presented in the literature is inconsistent, diverse, and unknown, especially for text mining usage. Therefore, we aim to analyze patterns of phenotyping definitions as a first step toward developing a text mining application to improve phenotype definition. A set random of observational studies was used for this analysis. Term frequency-inverse document frequency (TF-IDF) and Term Frequency (TF) were used to rank the terms in the 3958 sentences. Finally, we present preliminary results analyzing phenotyping definitions patterns.enPublisher Policytext miningbiomedical literaturephenotypingConference proceedings
