我们考虑在只有非唯一标识符（如姓名、性别、种族等）作为要链接的数据库中的公共标识符的情况下的记录链接问题。对于这种情况，可以在统计文献中找到有关记录链接的概率方法的大量工作。然而，尽管许多团体无疑仍然使用确定性程序，但关于确定性策略的文献并不多。此外，似乎几乎没有关于两种策略结果比较的文档。在这项工作中，我们将逐步确定性链接策略与概率策略（如在 AUTOMATCH 中实现）在已知真相的情况下进行比较。该比较是根据地区围产期重症监护中心数据库的医疗记录与佛罗里达州教育部的教育记录之间的联系进行的。两个数据库中都提供的社会安全号码用于在匹配后确定每个记录对的真实状态。比较了两种策略的匹配率和错误率，并讨论了它们的异同、优缺点。版权所有 (C) 2002 John Wiley Sons, Ltd.
We consider the problem of record linkage in the situation where we have only non-unique identifiers, like names, sex, race etc., as common identifiers in databases to be linked. For such situations much work on probabilistic methods of record linkage can be found in the statistical literature. However, although many groups undoubtedly still use deterministic procedures, not much literature is available on deterministic strategies. Furthermore, there appears to exist almost no documentation on the comparison of results for the two strategies. In this work we compare a stepwise deterministic linkage strategy with a probabilistic strategy, as implemented in AUTOMATCH, for a situation in which the truth is known. The comparison was carried out on a linkage between medical records from the Regional Perinatal Intensive Care Centers database and educational records from the Florida Department of Education. Social security numbers, available in both databases, were used to decide the true status of each record pair after matching. Match rates and error rates for the two strategies are compared and a discussion of their similarities and differences, strengths and weaknesses is presented. Copyright (C) 2002 John Wiley Sons, Ltd.
