12. A method for processing a drug information source, the method comprising creating a drug rule syntax comprising (a) drug rule syntax elements, each corresponding to a subset of a logical proposition, and (b) allowable logical relationships between said drug rule syntax elements; extracting metadata from the drug information source; extracting verbatim adverse event data from the drug information source; identifying at least one instance of drug rule content from the drug information source; mapping terms from verbatim data to a reference source; parsing drug rule elements from at least one identified instance of drug rule content into the drug rule syntax, retaining associations described in said drug rule content between those drug rule elements that form a drug rule; wherein the drug described by the drug information source is characterized by the set comprising: the syntax-parsed drug rule elements, the mapped terms, and the metadata.
