摘要

在许多情况下，当人们搜索数据库时，他们搜索的是最佳记录，而不是具有特定特征集的记录。使用布尔查询来开发搜索策略以找到最佳记录已被证明过于困难，特别是对于新手用户。我们构建了一个寻找最佳可选方案的最优决策策略，该策略同时考虑了持续搜索的期望值和搜索的成本。最优策略具有直观的吸引力，可以作为更复杂环境中启发式的基础。

An optimal search strategy based on user preferences for choice oriented databases

In many instances, when people search a database, they are searching for a best record instead of record with a particular set of characteristics. Using boolean queries to develop a search strategy to find a best record has proven too difficult, especially for novice users. We construct an optimal decision strategy for finding the best available alternative that takes into account both the expected value of continued search and the cost of search. The optimal strategy is intuitively appealing, and can be used as the basis for heuristics in more complex environments.
