    Abstract: A method, system and computer program product for generating answers to questions. In one embodiment, the method comprises receiving an input query, decomposing the input query into a plurality of different subqueries, and conducting a search in one or more data sources to identify at least one candidate answer to each of the subqueries. A ranking function is applied to each of the candidate answers to determine a ranking for each of these candidate answers; and for each of the subqueries, one of the candidate answers to the subquery is selected based on this ranking. A logical synthesis component is applied to synthesize a candidate answer for the input query from the selected the candidate answers to the subqueries. In one embodiment, the procedure applied by the logical synthesis component to synthesize the candidate answer for the input query is determined from the input query.

    Abstract: Methods/systems receive a question and automatically search sources of data containing passages to produce candidate answers to the question. The searching identifies passages that support each of the candidate answers based on scoring features that indicate whether the candidate answers are correct answers to the question. These methods/systems automatically create a scoring feature- specific matrix for each scoring feature. Each scoring feature-specific matrix has a score field for each different combination of text passage and question term (vector), and each score field holds a score value (vector value) indicating how each different combination of text passage and question term supports the candidate answers as being a correct answer to the question. Next, such methods/systems automatically combine multiple such vectors to produce a combined vector score for each of the candidate answers, and then rank the candidate answers based on the combined scores.

    Abstract translation: 方法/系统收到一个问题，并自动搜索包含段落的数据源，以产生候选题回答。 该搜索基于评分特征来识别支持每个候选答案的段落，所述评分特征指示候选答案是否是问题的正确答案。 这些方法/系统为每个评分特征自动创建一个评分特征专用矩阵。 每个得分特征专用矩阵对于文本通过和问题项（向量）的每个不同组合具有得分字段，并且每个得分字段保持指示文本通过和问题项的每个不同组合如何支持候选者的得分值（向量值） 答案是对这个问题的正确答案。 接下来，这些方法/系统自动组合多个这样的向量以产生每个候选答案的组合向量分数，然后基于组合分数对候选答案进行排序。
