Abstract
A system method for facilitating presentation of subject categorizations for use in an on-line search query engine is described. A synonym list is built including a set of synonym entries. Each synonym entry includes a synonym name and a heading code. The synonym list is arranged in order of synonym name. A search query is accepted from a user on the on-line search query engine. The search query is normalized into a standardized word form with at least one word in the standardized word form matching one of the synonym names in the synonym list. Each of the synonym entries in the synonym list having at least one synonym name matching the at least one word in the standardized word form is retrieved. A heading list including a set of heading entries is accessed. Each heading entry includes a heading name and a heading code. The heading list is arranged in order of heading code. Subject categorizations are presented as the heading names from each entry in the heading list having a heading code matching one of the heading codes in each of the retrieved synonym list entries.
