Abstract

A natural language query is received, and an answer to the natural language query is determined. A message is formatted such that the message includes the answer, and metadata corresponding to the answer, the metadata including information to enable construction, using the metadata, of a sentence that rephrases the query and recites the answer.

the metadata includes information to enable construction by the computing device, using the metadata, of the sentence or statement so that the sentence or statement describes the electronic object and/or contents of the electronic object.

11. The computer readable storage medium or media of claim 10, wherein

the electronic object comprises a picture;

and

the metadata includes descriptive information regarding content of the picture to enable construction by the computing device, using the metadata, of the sentence or statement so that the sentence or statement describes content of the picture.

12. A system for providing information, comprising:

a network interface device to communicatively couple to a communication network;

one or more processors configured to;

receive a natural language query;

determine an answer to the natural language query;

format one or more electronic messages that include;

the answer, and

metadata corresponding to the answer, the metadata separate from the answer and including information to enable construction by a computing device, using the metadata, of a syntactically correct natural language sentence or statement that recites and/or describes the answer, wherein the information to enable construction comprises information (i) indicating how the natural language query was interpreted in determining the answer and (ii) not included in the query; and

cause the network interface device to transmit the one or more electronic messages via the communication network.

13. The system of claim 12, wherein the metadata includes information to enable construction by the computing device, using the metadata, of the sentence or statement so that the sentence or statement further rephrases the query.

14. The system of claim 12, wherein:

the answer comprises an electronic object; and

the metadata includes information to enable construction by the computing device, using the metadata, of the sentence or statement so that the sentence or statement describes the electronic object and/or contents of the electronic object.

15. A method for providing information, the method comprising:

receiving, at one or more processors, a natural language query;

receiving, via a communication network, one or more first electronic messages that include

an answer to the natural language query, and

metadata corresponding to the answer, the metadata separate from the answer and including information to enable construction by a computing device, using the metadata, of a syntactically correct natural language sentence or statement that recites and/or describes the answer, wherein the information to enable construction comprises information (i) indicating how the natural language query was interpreted in determining the answer and (ii) not included in the query; and

generating, at one or more processors, the syntactically correct natural language sentence or statement that recites and/or describes the answer using the metadata in the one or more first electronic messages.

16. The method of claim 15, further comprising:

transmitting, via the communication network, a second electronic message that includes the natural language query;

wherein the one or more first electronic messages are responsive to the second electronic message.

17. The method of claim 15, wherein:

the metadata includes information to enable construction by the computing device, using the metadata, of the natural language sentence or statement so that the natural language sentence or statement further rephrases the query.

18. The method of claim 15, wherein generating the natural language sentence or statement further uses the answer.

19. The method of claim 15, wherein:
