Some aspects of knowledge base creation can be partially or completely automated, resulting in higher quality and smaller effort. Computer assistance is particularly valuable in ensuring the internal consistency of a knowledge base. The article describes several techniques for consistency enforcement in QMR-KAT, an interactive knowledge base editor for the INTERNIST-I/QMR medical knowledge base. Two strategies that improve consistency are applicable to a wide range of situations. The first strategy prevents simple (but common) inconsistencies. The second strategy reveals facts that are potentially (but not necessarily) inconsistent with known data, and may require further evaluation. Both strategies use the contents of the existing knowledge base in the evaluation of new facts.
知识库创建的某些方面可以部分或完全自动化，从而提高质量并减少工作量。计算机辅助在确保知识库的内部一致性方面特别有价值。本文描述了QMR-KAT（一种用于INTERNIST-I/QMR医学知识库的交互式知识库编辑器）中几种用于一致性强制的技术。两种提高一致性的策略适用于广泛的情况。第一种策略可防止简单（但常见）的不一致情况。第二种策略揭示可能（但不一定）与已知数据不一致的事实，可能需要进一步评估。两种策略在评估新事实时都使用现有知识库的内容。
