    • A search system (200) for a database (224) including records having a multiple disparate types of media is provided. The search system supports queries, that include different types of search criteria, including content based retrieval search criteria. A fuzzy logic method (400) is provided for effectively combining the results of different types of search criteria. The fuzzy logic method also allows confidence levels entered by the user for search criteria to be considered in combining results. Retrieval relevance values for documents for at least some search criteria are used in the fuzzy logic method. For content based image retrieval searches, the retrieval relevance values are computed by mapping a distance between quantitative characterizations of a search basis image, and other images into a finite range.
    • 提供了包括具有多种不同类型的媒体的记录的数据库(224)的搜索系统(200)。 搜索系统支持查询,包括不同类型的搜索条件,包括基于内容的检索搜索条件。 提供了一种模糊逻辑方法(400),用于有效地组合不同类型的搜索标准的结果。 模糊逻辑方法还允许在组合结果时考虑用户输入的搜索条件的置信度。 在模糊逻辑方法中使用至少一些搜索条件的文档的检索相关性值。 对于基于内容的图像检索搜索,通过将搜索基础图像和其他图像的定量表征之间的距离映射到有限范围来计算检索相关性值。
