摘要： A system has a processor coupled to access a document database that indexes keywords and instances of entities having entity types in a plurality of documents. The processor is programmed to receive an input query including one or more keywords and one or more entity types, and search the database for documents having the keywords and entities with the entity types of the input query. The processor is programmed for aggregating a respective score for each of a plurality of entity tuples across the plurality of documents. The aggregated scores are normalized. Each respective normalized score provides a ranking of a respective entity tuple, relative to other entity tuples, as an answer to the input query. The processor has an interface to a storage or display device or network for outputting a list including a subset of the entity tuples having the highest normalized scores among the plurality of entity tuples.
摘要翻译：系统具有处理器，其耦合到访问文档数据库，所述文档数据库在多个文档中对具有实体类型的关键字和实体的实例进行索引。处理器被编程为接收包括一个或多个关键字和一个或多个实体类型的输入查询，并且搜索数据库中具有关键词和具有输入查询的实体类型的实体的文档。处理器被编程用于聚集跨多个文档的多个实体元组中的每一个的相应分数。综合得分归一化。每个相应的归一化分数提供相对于其他实体元组的相应实体元组作为输入查询的答案的排序。处理器具有到存储或显示设备或网络的接口，用于输出包括多个实体元组中具有最高归一化分数的实体元组的子集的列表。
