Abstract

A method and a system for providing snippets of source documents of an answer to a fact query are disclosed. Snippets of source documents may be provided in response to a user request for the source documents from which the fact answer to a fact query was extracted. The snippets include the terms of the fact query and terms of the answer. The snippets may be displayed along with Uniform Resource Locators (URL'"'"'s) of the source documents.

Claims

1. A method for responding to a factual query, comprising:

receiving a user-formulated factual query, the factual query including one or more query terms;

identifying, from a fact repository, an answer to the factual query, the answer including one or more factual answer terms, wherein the fact repository includes a plurality of objects, the plurality of objects including a respective object having a list of a plurality of sources of the answer;

searching a document database distinct from the fact repository to identify documents matching the user formulated factual query; and

generating a response including both factual information that answers the factual query, wherein the factual information is from the fact repository, and information, distinct from the factual information, identifying at least a subset of the documents identified from the document database.

2. The method of claim 1, including:

generating a snippet for a source corresponding to the answer, the snippet including one or more query terms of the factual query and one or more of the factual answer terms of the answer; and

including the snippet in the generated response.

3. The method of claim 2, wherein generating the response further comprises highlighting within the snippet the one or more terms of the factual query and the one or more factual answer terms of the answer.

4. The method of claim 2, wherein identifying the answer includes identifying a respective factual answer term that comprises one or more words or numbers, and wherein generating the snippet includes:

identifying a text portion of a respective source that includes the identified factual answer term and generating the snippet so as to include the identified text portion that includes the identified respective factual answer term.

5. The method of claim 1, wherein:

the identifying includes identifying for the answer one or more source documents;

the method includes;

accessing at least one of the source documents in the document database; and

generating a snippet for at least one of the source documents, the snippet including one or more query terms of the factual query and one or more of the factual answer terms of the answer; and

the generated response includes the snippet.

6. The method of claim 1, wherein:

the identifying includes identifying for the answer one or more source documents; and

the generating includes generating a list of a subset of the one or more source documents.

7. The method of claim 6, further comprising:

presenting a response to the user, wherein the response includes the factual information that answers the factual query, a link to a source of the factual information, a link to the list of the subset of the one or more source documents, and the subset of documents identified from the document database.

8. The method of claim 1, further comprising:

presenting a response to the user, wherein the response includes the factual information that answers the factual query, a link to a source of the factual information, and the subset of documents identified from the document database.

9. The method of claim 1, wherein:

generating the response includes determining a proximity of the one or more query terms and the one or more factual answer terms in at least one of the sources.

10. A system, for responding to a factual query, comprising:

one or more central processing units for executing programs;

memory storing one or more programs be executed by the one or more central processing units;

the one or more programs comprising instructions for;

receiving a user-formulated factual query, the factual query including one or more query terms;

identifying, from a fact repository, an answer to the factual query, the answer including one or more factual answer terms, wherein the fact repository includes a plurality of objects, the plurality of objects including a respective object having a list of a plurality of sources of the answer;

searching a document database distinct from the fact repository to identify documents matching the user formulated factual query; and

generating a response including both factual information that answers the factual query, wherein the factual information is from the fact repository, and information, distinct from the factual information, identifying at least a subset of the documents identified from the document database.

11. The system of claim 10, further comprising instructions for:

generating a snippet for a source corresponding to the answer, the snippet including one or more query terms of the factual query and one or more of the factual answer terms of the answer; and

including the snippet in the generated response.

12. The system of claim 11, wherein:

instructions for generating the response further comprises instructions for highlighting within the snippet the one or more terms of the factual query and the one or more factual answer terms of the answer.

13. The system of claim 11, wherein:

instructions for identifying the answer include instructions for identifying a respective factual answer term that comprises one or more words or numbers, and

instructions for generating the snippet include;

instructions for identifying a text portion of a respective source that includes the identified factual answer term and generating the snippet so as to include the identified text portion that includes the identified respective factual answer term.

14. The system of claim 10, further comprising instructions for:

identifying for the answer one or more source documents;

accessing at least one of the source documents in the document database; and

generating a snippet for at least one of the source documents, the snippet including one or more query terms of the factual query and one or more of the factual answer terms of the answer; and

including the snippet in the generated response.

15. The system of claim 10, further comprising instructions for:

identifying for the answer one or more source documents; and

generating a list of a subset of the one or more source documents.

16. The system of claim 10, further comprising instructions for:

presenting a response to the user, wherein the response includes the factual information that answers the factual query, a link to a source of the factual information, and the subset of documents identified from the document database.

17. The system of claim 15, further comprising instructions for:

presenting a response to the user, wherein the response includes the factual information that answers the factual query, a link to a source of the factual information, a link to the list of the subset of the one or more source documents, and the subset of documents identified from the document database.

18. A computer readable storage medium storing one or more programs configured for execution by a computer, the one or more programs comprising instructions for:

receiving a user-formulated factual query, the factual query including one or more query terms;

identifying, from a fact repository, an answer to the factual query, the answer including one or more factual answer terms, wherein the fact repository includes a plurality of objects, the plurality of objects including a respective object having a list of a plurality of sources of the answer;

searching a document database distinct from the fact repository to identify documents matching the user formulated factual query; and

generating a response including both factual information that answers the factual query, wherein the factual information is from the fact repository, and information, distinct from the factual information, identifying at least a subset of the documents identified from the document database.

19. The computer readable storage medium storing of claim 18, further comprising instructions for:

generating a snippet for a source corresponding to the answer, the snippet including one or more query terms of the factual query and one or more of the factual answer terms of the answer; and

including the snippet in the generated response.

20. The computer readable storage medium storing of claim 19, wherein:

instructions for generating the response further comprises instructions for highlighting within the snippet the one or more terms of the factual query and the one or more factual answer terms of the answer.

21. The computer readable storage medium storing of claim 19, wherein:
