Neat idea but would it be simpler to just group web elements with the same css tags? A computer vision approach seems a bit over-engineered.

@epage480 This isn't a CV approach, it's a grouping similar object from HTML, if you want to help to implement this paper with us let me know, here the reference A Web Page Segmentation Approach Using Visual Semantics

@lurenss, I would much rather focus on this paper, an empirical comparison of web page segmentation algorithms, 2021.

much more recent and detailed comparison of all major web page segmentation algorithms.

tl;dr - microsoft's VIPS algorithm is still the best one out there; you can find implementations in java, JS or python.
