Tag/Size Ratio
For each document
we examined the ratio of the total number of tags
to its size.
The graph below contains the results.
An interesting pattern emerges - rays radiating out from the
origin, indicating a number of documents with constant tag/size
ratios. One such ray is indicated by the green ellipse.
We examined a number of these rays and determined that
they represented different versions of the same document
(occurring in archives or mirrored sites). This suggests that
the tag/size ratio might be used as a component of a signature
for an HTML document, e.g., for purposes of copy detection.
