I tried a handful of searches. I got some useful hits and some that
were way off - not surprising in an automated search system.
The searching itself seems to me less effective than Pubmed or
cancer.gov. That's also not surprising given the huge amounts of money,
time, and talent invested in those two government websites.
A bigger problem perhaps is that the data you return has no provenance.
We don't know what the source for the information is. We don't know
what evidence supports it. We don't know where it was originally
published or who the authors were or what their credentials are. This
makes the information much less reliable than it could be.
But it's good that you're working on it.
I'm curious to know why you're working on it? Is this a research
project in information retrieval? Is it a research project in medical
information delivery? Is it a prototype for a commercial product?
It would be very helpful if you were to put an "About us" link on your
page and a link to a description of the project.
If you're trying to do research on information retrieval, either for
academic or commercial purposes, I also suggest that you put some
buttons on your search results page to enable people to rank the
relevance and quality of each hit you provide. That will enable you to
figure out where you are doing well and where you are doing poorly -
perhaps enabling to do more of the former and less of the latter.
Thanks.
