Hello all,
I'm using BaseX to cluster a set of millions of small XML fragments which look
something like this:
<affiliation>
<organization>Institut für Organische Chemie der Universität
Heidelberg</organization>
<country iso-code="DEU"/>
</affiliation>
I need to cluster based on fragment similarity - so taking into account
elements, attributes and text nodes.
If I use the entire XML fragment as a grouping key, something like this:
for $a at $c in db:open('DB')/item/*/affiliation
group by $val := $a
... then will the grouping be equivalent to the functionality of the deep-equal
function? First results seem to suggest this, but I want to make sure that
grouping is not done on text node value alone or anything like that.
Incidentally, BaseX is simply unbelievably fast at executing this - a million
fragments clustered and written out to another DB in 16 seconds on a laptop. My
congratulations on an amazing product.
Regards,
Constantine
