Abstract
To archive information, a phrase or sentence describing the information, typically expressed in a natural language and conforming to the rules of a grammar (like a natural language grammar) is used to create a structured index which also conforms to the natural language grammar. The structured index has structure because the words in the index have a function and a relationship among each other as determined by the grammar. The index is combined with a location pointer of information to be cataloged, preferably multimedia information, to form a matched pair, i.e., a structured index and a segment (or a pointed to a multimedia object). The matched pair is stored in a database for later retrieval. Retrieval is based on parsing a query into a query structure that is identical or similar to the structured index. A heuristic interface presents the multimedia information along with a template in order to prompt the user into describing the multimedia information with a string of words so that they conform to the grammar.
