Classifying disease outbreak reports using n-grams and semantic features.
Conway M, Doan S, Kawazoe A, Collier N. Conway M, et al. Int J Med Inform. 2009 Dec;78(12):e47-58. doi: 10.1016/j.ijmedinf.2009.03.010. Epub 2009 May 15. Int J Med Inform. 2009. PMID: 19447070
RESULTS: A feature representation composed of unigrams, bigrams, trigrams and features derived from a semantic tagger, in conjunction with the Naïve Bayes algorithm and feature selection yielded the highest classification accuracy (and F-score). This result was stat …

Structuring an event ontology for disease outbreak detection.
Kawazoe A, Chanlekha H, Shigematsu M, Collier N. Kawazoe A, et al. BMC Bioinformatics. 2008 Apr 11;9 Suppl 3(Suppl 3):S8. doi: 10.1186/1471-2105-9-S3-S8. BMC Bioinformatics. 2008. PMID: 18426553 Free PMC article.
This event ontology is designed to support timely detection of disease outbreaks and rapid judgment of their alerting status by 1) bridging a gap between layman's language used in disease outbreak reports and public health experts' deep knowledge, and 2) making multi-lingu …
