<p>Hi Liam,</p>
<p><br>
</p>
<p>If you want to count usage and abstract the service, you would
probably ultimately want to end up with a ServiceCall data
object. As this would faciltate both these goals, it would also
mean you would have a historical record of service calls which
could help debugging issues. This does feel a little bit
over-the-top but if you keep the data object as succinct as
possible (e.g. servicecallid, type, timestamp, request_params,
response, response_code) then this probably would no be too
difficult to implement. There may be other things that could be
stored but as these may vary between different services. It is
probably best to leave this to user-defined configuration.</p>
<p><br>

Absolutely! This wasn't really meant to be production ready and
just a quick experiment. There are multiple ways to do this, you
could for instance do some sort of AJAX call and show the
results as suggested keywords, or as you say add them via the
event queue. One thing I would probably want to do before
putting it in production would be to have some way of monitoring
the number of Azure API calls that had been made as, like many
services in the cloud, the price you pay depends on how much you
use it. I'd probably want to abstract the service used as well
so that people can use their favoured provider (if they have
equivalent services).</div>

<p>One thing I forgot to mention was that this call is probably
better as an event queue task rather than a before commit
trigger. As if you are relying on a third-party application
you don't want to be waiting on this before the page can
reload. If you are only send the abstract that is probably
going to be fairly rapid. However, sometimes abstracts can be
rather long and I can imagine the service being less
responsive at times. So you may wait a while before you get a
response back, so you can reload the page. Obviously the
disadvantage of having an event queue task is that you will
end up with two revisions rather than one. However, your code
at the moment suggests this service will only be called once,
as once there are keywords it cannot be run again.
<br>
</p>
<p><br>
</p>
<p>Just another thought: If you were to change this so keywords
could be updated, obviously you would want to check to see the
fields that were being sent for keywords analysis had changed
and only call this service if they had. You would also need
some code to parse the current and returned keywords to merge
them together.<br>

<p>Hi Liam,</p>

<p>Looks interesting. I have been working on improving search
on keywords within EPrints by introducing a new Keywords
MetaField type that is backwards with the Longtext MetaField
that is currently the type with the keywords field. I have
also introduced a Idci (short for ID Case Insentive) field
that could be used for keywords when set to be a multiple
field. Hopefully, I will be able to make the official
release of 3.4.2 that includes these available this week.</p>

I've been experimenting with integrating EPrints with an
off the shelf AI solution to generate keywords. The
service I used was the Text Analytics service element of
the Microsoft Azure Text Analytics. I've only gone as far
as experimenting with the Key Phrases endpoint so far, but
the Named Entities endpoint looks like it could add real
value to EPrints records too.</div>
