    • Roughly described, a database searching method for searching a database, in which hits are ranked in dependence upon an information measure of itoms shared by both the hit and the query. The information measure can be a Shannon information score, or another measure which indicates the information value of the shared itoms. An itom can be a word or other token, or a multi-word phrase, and can overlap with each other. Synonyms can be substituted for itoms in the query, with the information measure of substituted itoms being derated in accordance with a predetermined measure of the synonyms' similarity. Indirect searching methods are described in which hit from other search engines are re-ranked in dependence upon the information measures of shared itoms. Structured and completely unstructured databases may be searched, with hits being demarcated dynamically. Hits may be clustered based upon distances in an information-measure-weighted distance space.
    • 粗略地描述了一种用于搜索数据库的数据库搜索方法,其中命中根据命中和查询共享的itom的信息度量进行排名。 信息度量可以是香农信息评分,或者指示共享信息的信息值的另一个度量。 itom可以是单词或其他令牌,或多个单词的短语,并且可以相互重叠。 同义词可以替代查询中的itom,根据同义词相似性的预定度量,取代的itom的信息度量被降级。 描述间接搜索方法,其中来自其他搜索引擎的命中根据共享itom的信息度量重新排序。 可以搜索结构化和完全非结构化的数据库,动态地划分命中。 点击可以基于信息测量加权距离空间中的距离进行聚类。
