A method, system and a computer program product are provided for scoring candidate answers for geographic relevance analyzing an input question to identify one or more first geographic foci of the input question based on geographical contextual information associated with the input question, identifying one or more second geographic foci for a candidate answer generated in response to the input question, and then comparing the first and second geographic foci to generate a geographic relevance score for the candidate answer to the input question.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method of scoring candidate answers for geographic relevance, the method comprising: receiving, by an information handling system, comprising a processor and a memory, an input question for answering by the information handling system; analyzing, by the information handling system, the input question to identify one or more first geographic foci of the input question based on geographical contextual information associated with the input question; processing, by the information handling system, a corpus of documents based on the input question to generate a candidate answer to the input question; identifying, by the information handling system, one or more second geographic foci for the candidate answer; and generating, by the information handling system, a geographic relevance score for the candidate answer based at least in part on a comparison of the one or more first geographic foci for the received input question and the one or more second geographic foci for the candidate answer. 2. The method of claim 1, where analyzing the input question comprises identifying a definite location expression for the input question, by the information handling system, from geographical contextual information associated with the input question, and processing the definite location expression to identify the one or more first geographic foci of the input question. 3. The method of claim 2, where the definite location expression is identified from geographical contextual information comprising a current location of a user who submitted the input question. 4. The method of claim 2, where the definite location expression is identified from geographical contextual information comprising a user-associated location for a user who submitted the input question. 5. The method of claim 2, where processing the definite location expression comprises normalizing the definite location expression for the input question. 6. The method of claim 1, where identifying one or more second geographic foci for the candidate answer comprises: identifying, by the information handling system, document location information associated with a corpus document; and associating, by the information handling system, each token in the corpus document with the document location information associated with the corpus document. 7. The method of claim 6, where identifying document location information comprises analyzing, by the information handling system, the corpus document to determine a document relevance location based on at least one of metadata or content of the corpus document. 8. The method of claim 7, where identifying document location information further comprises associating, with each definite locative expression contained in the corpus document, a location with the definite locative expression so that the one or more second geographic foci for the candidate answer is generated based on at least one of the document relevance location or the location of the definite locative expression. 9. The method of claim 1, where generating the geographic relevance score comprises: analyzing, by the information handling system, the input question to categorize the input question as location-non-monotonic or location-upward-monotonic; and scoring the candidate answer with a first geographic relevance score based on whether the one or more first geographic foci for the received input question geographically matches or includes the one or more second geographic foci for the candidate answer. 10. A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on an information handling system, causes the system to score candidate answers for geographic relevance by: receiving an input question for answering by the system; analyzing the input question to identify one or more first geographic foci of the input question based on geographical contextual information associated with the input question; processing a corpus of documents based on the input question to generate a candidate answer to the input question; identifying one or more second geographic foci for the candidate answer; and generating a geographic relevance score for the candidate answer based at least in part on a comparison of the one or more first geographic foci for the received input question and the one or more second geographic foci for the candidate answer. 11. The computer program product of claim 10, wherein the computer readable program, when executed on the system, causes the system to analyze the input question by identifying a definite location expression for the input question from geographical contextual information associated with the input question, and processing the definite location expression to identify the one or more first geographic foci of the input question. 12. The computer program product of claim 11, wherein the computer readable program, when executed on the system, causes the system to identify the definite location expression from geographical contextual information comprising a current location of a user who submitted the input question. 13. The computer program product of claim 11, wherein the computer readable program, when executed on the system, causes the system to identify the definite location expression from geographical contextual information comprising a user-associated location for a user who submitted the input question. 14. The computer program product of claim 11, wherein the computer readable program, when executed on the system, causes the system to process the definite location expression by normalizing the definite location expression for the input question. 15. The computer program product of claim 11, wherein the computer readable program, when executed on the system, causes the system to generate the geographic relevance score by: analyzing the input question to categorize the input question as location-non-monotonic or location-upward-monotonic; and scoring the candidate answer with a first geographic relevance score based on whether the one or more first geographic foci for the received input question geographically matches or includes the one or more second geographic foci for the candidate answer. 16. An information handling system comprising: one or more processors; a memory coupled to at least one of the processors; a set of instructions stored in the memory and executed by at least one of the processors to score candidate answers for geographic relevance, wherein the set of instructions are executable to perform actions of: analyzing, by the system, the input question to identify one or more first geographic foci of the input question based on geographical contextual information associated with the input question; processing, by the system, a corpus of documents based on the input question to generate a candidate answer to the input question; identifying, by the system, one or more second geographic foci for the candidate answer; and generating, by the system, a geographic relevance score for the candidate answer based at least in part on a comparison of the one or more first geographic foci for the received input question and the one or more second geographic foci for the candidate answer. 17. The information handling system of claim 16, wherein analyzing the input question comprises identifying a definite location expression for the input question from geographical contextual information associated with the input question, and processing the definite location expression to identify the one or more first geographic foci of the input question. 18. The information handling system of claim 17, wherein the definite location expression is identified from geographical contextual information comprising a current location of a user who submitted the input question. 19. The information handling system of claim 17, wherein the definite location expression is identified from geographical contextual information comprising a user-associated location for a user who submitted the input question. 20. The information handling system of claim 17, wherein processing the definite location expression comprises normalizing the definite location expression for the input question.
