Record matching in database system

A computer-implemented method includes processing an unstructured object for each of records of a database for identifying a set of one or more attribute values in the unstructured object for each record. Two recorded sets of unstructured attribute values of a database may be compared for determining a degree of similarity between the two sets. Based on a result of the comparison, it may be determined whether the two records represent the same entity. 一种计算机实现的方法包括：处理数据库的记录中的每个记录的非结构化对象，以用于识别每个记录的非结构化对象中的一个或多个属性值的集合。可以比较数据库的两个记录的非结构化属性值集合，以用于确定两个集合之间的相似程度。可以基于比较结果，确定两个记录是否代表相同的实体。
