摘要: In a database data processing system, input search data is matched against an index of a database to determine database records which either closely or exactly match the input search data. The input search data is broken down into elements, and elements are converted to terms having a finite set of possible values. The Soundex function may be used to convert elements to terms. The terms are compared against an index of terms to determine which database records relate to the input search data. Through statistical analysis, match records are given a record weight which may be used to calculate how closely the input data actually is to each match record. The invention provides a fast and efficient way of accurately searching for data in extremely large databases, while not requiring precise input search data entry. The invention may also be used to compare or supplement one database against another.
摘要翻译: 在数据库数据处理系统中,将输入搜索数据与数据库的索引进行匹配以确定与输入搜索数据紧密或完全匹配的数据库记录。 输入搜索数据被分解为元素,元素被转换成具有有限可能值集合的项。 Soundex函数可用于将元素转换为术语。 将这些术语与术语索引进行比较,以确定哪些数据库记录与输入搜索数据相关。 通过统计分析,给出匹配记录的记录权重,可以用于计算输入数据实际上与每个匹配记录的接近程度。 本发明提供了一种快速有效的方式来精确搜索极大数据库中的数据,同时不需要精确的输入搜索数据输入。 本发明还可以用于将一个数据库与另一个数据库进行比较或补充。
