摘要

提出了一种基于模式的方法，用于在无法获得准确答案或生成时间过长的情况下导出近似和内涵的查询答案。如果有更多的时间，可以对近似和深入的查询答案进行改进。由于在生成最终结果的最后一步之前，基于模式的查询处理主要执行基于主存的操作，而不需要访问数据库，因此在实时应用程序中，它应该比传统的查询处理提供更快的查询响应

A pattern-based approach for deriving approximate and intensional answers

A pattern-based approach is proposed to derive the approximate and intensional query answers when the exact answer is unavailable or too time-consuming to generate. The approximate and intensional query answers may be refined if more time is available. Since the pattern-based query processing performs mainly main-memory based manipulations without database access until the last step of generating the final results, it should provide faster response to queries than the conventional query processing in real-time applications.<>
