In Textual Near Duplicate analysis, what does a similarity score of 0 indicate?

A similarity score of 0 in Textual Near Duplicate analysis signifies that the document is classified as standalone, meaning it does not share any textual content with other documents in the analysis. This indicates that the document is unique in its content and has no significant overlap with any other compared documents.

In the context of the other options, a score that indicates similarity would not point to the document being part of a large group of similar documents or being highly similar to others. Additionally, while it might suggest that the document has some characteristics that could align with the idea of containing no text, a score of 0 specifically emphasizes independence in content rather than a lack of text altogether. Thus, the score clearly denotes the document's unique standing in relation to other documents being analyzed.
