Natural language processing for a location-based services system

Abstract

A method and system for providing natural language processing in a communication system is disclosed. A voice request is generated with a remote terminal that is transmitted to a base station. A voice recognition application is then used to identify a plurality of words that are contained in the voice request. After the words are identified, a grammar associated with each word is also identified. Once the grammars have been identified, each word is categorized into a respective grammar category. A structured response is then generated to the voice request with a response generation application.

Description

[0001] This application claims the benefit of U.S. Provisional Application Serial No. 60 / 286,916, filed Apr. 27, 2001.[0002] The present invention relates generally to a natural language processing application and, more particularly, to providing an enhanced natural language processing application for interpreting structured requests for products and services in a location-based services system.[0003] Wireless communication devices have recently evolved from a technology used by an elite segment of the population to a technology that is used by the masses. In the year 2000, it has been estimated that well over 100 million people in the United States alone subscribed to at least one type of wireless communication service. Worldwide, the number of wireless communication device users has reached a staggering number and is growing all of the time. In the near future, it is envisioned that almost everyone will own or use some sort of wireless communication device that is capable of perfo...

AI Technical Summary

Benefits of technology

This approach enhances user experience by providing more accurate and relevant responses to voice requests, reducing the need for extensive setup and maintenance, and ensuring that users receive information about products and services available in their vicinity, thereby improving the usability of wireless communication devices for business information retrieval.

Problems solved by technology

Currently, most of these devices are only used by a small segment of the population due, in large part, to the fact that there are a limited number of applications and services available for such devices.

Generally speaking, one of the problems associated with searching for business information on specific products and services using the Internet is being able to locate relevant business information for products and services that are available in a geographic area that is located near the user.

While this enables a system to recognize content contained in an utterance, it places a significant burden on the developer both before and after the system is deployed.

Additionally, due to the various speech patterns and utterances, it is currently impossible to obtain a near 100% successful recognition of utterances.

While current speech recognition engines are tuned to interpret sound, they cannot interpret meaning or understanding of context.
