1. A computer-implemented method for integrating textual data from disparate data sources in order to have data standardization with respect to the textual data, comprising: receiving an input stream of textual data from one or more of the disparate data sources; wherein the input stream of textual data is related to a predetermined category; accessing character-level rules that are related to the predetermined category and that define how the input stream is to be segmented into textual data elements through pattern matching; applying the rules to the input stream to determine the textual data elements in the input stream; and outputting the textual data elements to a morphological parser; wherein the morphological parser provides semantic analysis of the textual data elements for integrating the textual data elements in order to have data standardization with respect to the textual data.
