Abstract
A method and apparatus for classifying textual data is provided. The invention is adapted to automatically classify text. In particular, the invention utilizes a sparse vector framework to evaluate natural language text and to accurately and automatically assign that text to a predetermined classification. This can be done even where the disclosed system has not seen an example of the exact text before. The disclosed method and apparatus are particularly well-suited for coding adverse event reports, commonly referred to as “verbatims,” generated during clinical trials of pharmaceuticals, The invention also provides a method and apparatus that can be used to translate verbatims that have already been classified according to one coding scheme to be translated to another coding scheme in a highly automated process.
