检索的有效性的自动方法，使用相关性判断的积极和消极的条款之间的关系的确定进行评估。通过使用具有术语匹配组件、正术语关系组件和负术语关系组件的广义相似性函数，将术语关系并入到检索过程中。两种策略，查询划分和查询聚类，用于评估的有效性的长期关系进行了研究。从语言学和经济学的角度来看，后者似乎更有吸引力。验证了正关系和负关系在单独使用和组合使用时均有效。检索结果表明，检索词间关系分量相对于检索词匹配分量的重要性对检索性能有显著影响。判别分析作为一种技术，用于确定这些组件的相对重要性的有用性进行了研究。
The retrieval effectiveness of an automatic method that uses relevance judgments for the determination of positive as well as negative relationships between terms is evaluated. The term relationships are incorporated into the retrieval process by using a generalized similarity function that has a term match component, a positive term relationship component, and a negative term relationship component. Two strategies, query partitioning and query clustering, for the evaluation of the effectiveness of the term relationships are investigated. The latter appears to be more attractive from linguistic as well as economic points of view. The positive and the negative relationships are verified to be effective both when used individually, and in combination. The importance attached to the term relationship components relative to that of term match component is found to have a substantial effect on the retrieval performance. The usefulness of discriminant analysis as a technique for determining the relative importance of these components is investigated.
