Abstract
A system for scoring a discussion thread having posts in a question-and-answer form is provided. The system receives a query and then identifies features of the discussion thread that may include one or more term features and one or more non-term features. A term feature may be a combined post feature that combines the terms of multiple posts to treat them as a single document. A term feature may be a question feature that contains the question of the discussion thread. A term feature may also be a question post feature that contains the terms of the post that relate to the question of the post. The system then generates a feature score for each feature and combines the feature scores into a relevance score indicating the relevance of the discussion thread to the query. The system may also use the relevance score when ranking discussion threads.
