Are you suggesting writing an implementation quickly and seeing what
happens with some real queries? Because that does sound like a good
way of deciding whether the algorithm is useful in our case, but you
don't have long -- about three days -- until your proposal need to be
in, so I don't know if you have enough time to do that and write
everything up.

Alternatively, if you have an algorithm you are confident will be fast
enough and provide some useful clustering, then you could implement
that, and as a stretch goal in the project extend the system to allow
other algorithms to be used, and look then at implementing LSI. (If
you've delivered something earlier in the project, it'd be fine to do
something a bit more speculative later.)
