Abstract: An automated grammar generator is disclosed, which is operable to receive a speech or text segment. The automated grammar generator identifies one or more parts of the segment suitable for processing into a natural language expression. The natural language expression is an expression which a person might use to refer to the segment. The automatic grammar generator generates one or more phrases from the segment, each of the one or more phrases corresponding to or capable of it being processed into a natural language expression or utterance suitable for referencing the text or speech segment. Noun phrases and verb phrases and other syntactic structures are identified in the speech or text segment, and modified to produce typical natural language expressions or utterances a user might employ to reference a segment. Verbs in verb phrases may be modified in order to provide further natural language expressions or utterances for use in the grammar.
