    • A similarity detector detects similar or near duplicate occurrences of a document. The similarity detector determines similarity of documents by characterizing the documents as clusters each made up of a set of term entries, such as pairs of terms. A pair of terms, for example, indicates that the first term of the pair occurs before the second term of the pair in the underlying document. Another document that has a threshold level of term entries in common with a cluster is considered similar to the document characterized by the cluster.
    • 相似性检测器检测文档的类似或接近重复的出现。 相似度检测器通过将文档表征为各自由诸如术语对的一组术语条目组成的簇来确定文档的相似性。 例如,一对术语表示该对中的第一项出现在基础文档中该对的第二项之前。 具有与集群相同的术语条目的阈值级别的另一文档被认为与由集群表征的文档类似。
