System and method for assessing TV-related information over the internet
First Claim
1. A system for accessing supplemental network-resident information about an audio/video program comprising:
- a network connection through which network-resident information may be obtained;
a speech recognizer receptive of a user'"'"'s input speech request for information about a program;
a natural language parser coupled to said speech recognizer for extracting a semantic representation of the user'"'"'s request for information;
a data store for storing a representation of an electronic program guide, said program guide having an indicator identifying the program being enjoyed by said user at the time of said user'"'"'s request;
a search engine commander that issues at least one search request to at least one search engine through said network connection, wherein said search engine commander issues said at least one search request based on said semantic representation and using said representation of an electronic program guide as a first filter to constrain said search request to identify useful information relevant in determining what information the user is interested in retrieving;
a search results processor for receiving search results in response to said search request, for filtering said received search results based on the electronic program guide, and for providing a filtered portion of the received search results to the user as information about an audio/video program; and
at least one second filter, said second filter being used by said search results processor for selecting a first group of search results from said received search results and setting aside a second group of search results from said received search results, said second filter being customizable by the user; and
updating said information filters on a per-user basis based on historical data gathered as said use of the system.

Abstract
The system retrieves information from the internet using multiple search engines that are simultaneously launched by the search engine commander. The commander is responsive to a speech-enabled system including a speech recognizer and natural language parser. The user speaks to the system in natural language requests, and the parser extracts the semantic content from the user'"'"'s speech, based on a set of goal oriented grammars. The preferred system includes a fixed grammar and an updatable or downloaded grammar, allowing the system to be used without extensive training and yet capable of being customized for a particular user'"'"'s purposes. Results obtained from the search engines are filtered based on information extracted from an electronic program guide and from prestored user profile data. The results may be displayed on screen or through synthesized speech.

9. A method of conducting a search for network-resident information about an audio/video program, comprising the steps of:
-
processing a user'"'"'s input speech request for information about a program to generate a semantic representation;
formulating a search engine search request based on said semantic representation;
accessing a stored electronic program guide and using an electronic program guide to constrain said search request to identify useful information relevant in determining what information the user is interested in retrieving, said programming guide having an indicator identifying the program being enjoyed by said user at the time of said user'"'"'s request;
sending said constrained search request to at least one search engine over a network;
receiving search results from said at least one search engine;
filtering said received search results based on the electronic program guide; and
filtering said received search results for selecting a first group of search results from the said received search results and discarding a second group of search results from said received search results, said second filter being customizable by the user; and
updating said information filters on a per-user basis based on historical data gathered as said use of the system. - View Dependent Claims (10, 11, 12, 13)
