1. A method of recommending additional questions based on an input question to a question answering system, comprising:
- dividing the input question into a question topic and a question focus;
accessing an index of questions to identify stored questions having a similar question topic to the input question, but different question focus from the input question;
generating recommended questions by substituting the question focus for the identified stored questions for the question focus of the input question; and
outputting the recommended questions as the additional questions.

Abstract
The present system graphs topic terms in stored cQA questions and also converts a submitted question into a graph of topic terms. Topic terms that correspond to a question topic are delineated from topic terms that correspond to question focus. New questions are recommended to the user based on a comparison between the topics of the new questions and the topic of the submitted question as well as the focus of the new questions and the focus of the submitted question.

13. A system for recommending questions to a user of a community based question answering system, comprising:
-
an indexing system configured to generate an index of previously asked questions comprising; a topic chain generator configured to generate a topic chain for each previously asked question to be indexed, each topic chain being a linked set of topic terms, linked in an order based on a specificity of the topic terms occurring in the previously asked question being indexed; an indexing component configured to index the previously asked questions to be indexed based on the topic chains; a question answering system configured to recommend questions based on an input question, comprising; a question collection component configured to identify a set of topic chains in the index based on a topic chain generated for the input question; a topic and focus identifier component configured to identify topic terms corresponding to question topic and question focus in the topic chains identified in the index and the topic chain for the input question; and a recommendation component configured to generate and output recommended questions by substituting the topic terms corresponding to question focus in the topic chains identified in the index, for the topic terms corresponding to question focus in the topic chain for the input question. - View Dependent Claims (14, 15, 16, 17, 18)

19. A computer readable storage medium having computer executable instructions encoded thereon which, when executed by a computer, cause the computer to recommend additional questions to a user of a community-based question answering system by performing steps of:
-
generating topic chains of linked topic terms for each of a plurality of stored questions; generating a topic chain for the input question; identifying a set of topic chains for the stored questions based on the topic chain for the input question; building a question tree using the identified set of topic chains and the topic chain for the input question; dividing the question tree to identify topics and foci in the topic chains used to construct the question tree; and generating recommended questions by substituting the foci of the topic chains in the identified set of topic chains for the focus of the topic chain for the input question; and outputting the recommended questions if the substituted foci are sufficiently dissimilar from the focus of the topic chain for the input question. - View Dependent Claims (20)
