Automatic grammar generation using distributedly collected knowledge
First Claim
1. A computer based method for automatically generating a hierarchical grammar associated with a plurality of tasks comprising the steps of:
- creating a sub-grammar for each of the plurality of tasks, wherein creating a sub-grammar for a task comprises;
receiving data representing the task based from responses received from a distributed database;
automatically tagging the data into parts of speech to form tagged data using a processor executing instructions included in a memory coupled to the processor;
identifying filler words and core words from said tagged data by applying rules to differentiate between filler words and core words using the processor executing instructions included in the memory coupled to the processor;
automatically modeling sentence structure based upon said tagged data using a set of modeling rules retrieved from the memory coupled to the processor;
automatically identifying synonyms of said core words; and
automatically creating a sub-grammar using the modeled sentence structure, the tagged data, the identified synonyms, and the identified core words; and
creating a high-level grammar by combining filler words identified in the creation of the sub-grammars.

Abstract
The invention includes a computer based system or method for automatically generating a grammar associated with a first task comprising the steps of: receiving first data representing the first task based from responses received from a distributed network; automatically tagging the first data into parts of speech to form first tagged data; identifying filler words and core words from said first tagged data; modeling sentence structure based upon said first tagged data using a first set of rules; identifying synonyms of said core words; and creating the grammar for the first task using said modeled sentence structure, first tagged data and said synonyms.

12. A computer based system for automatically generating a hierarchical grammar associated with a plurality of tasks comprising:
-
creation means for creating a sub-grammar for each of the plurality of tasks, wherein the creation means comprises; receiving means for receiving data representing the task based from responses received from a distributed database; tagging means for automatically tagging the data into parts of speech to form tagged data; identification means for identifying filler words and core words from said tagged data by applying rules to differentiate between filler words and core words; modeling means for automatically modeling sentence structure based upon said tagged data using a set of modeling rules; synonym means for automatically identifying synonyms of said core words; and grammar means for automatically creating a sub-grammar using the modeled sentence structure, the tagged data, the identified synonyms, and the identified core words; and creation means for creating a high-level grammar by combining filler words identified in the creation of the sub-grammars. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
