3. A computer-assisted method of processing a drug information source, the drug information source comprising at least one instance of adverse event content, each instance of adverse event content comprising at least one adverse event characterization, 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; detecting at least one instance of adverse event content from a drug information source; and parsing at least one adverse event characterization from at least one detected instance of adverse event content, whereby a subset of the drug information source is processed into at least one parsed adverse event characterization, and wherein the at least one adverse event characterization comprises quantitatively explicit information.
