Hi all,
Thanks to everyone for their feedback to this project! Mike, we hadn't
considered the aging parameters as you described it, but I think it's an
excellent idea and it sounds like others agree. Let's all put our heads
together to see if we can make it happen. This is what I love about this
community! :)
Cheers!

The current plan would not take into account how recent the circs
(or holds) were, just that they were within a configurable time
period of the time the cronjob that counts them last ran (default
will likely be to include those from within the last 6 to 12
months). If you have an algorithm you think would work well and
are willing to share we would gladly include that as an option
when doing the work, though.
I do, and I am. As time permits over the next few weeks I'll get back
to this thread.
We would not, however, be able to make it a per-bump option with
the way we currently plan on storing the circ and hold counts, so
instead it would function as an overall modifier to the circ/hold
count numbers. Though even as I type this email I have thoughts on
how we could change that if the feeling is that it should be at
least partially bump-to-bump configurable.
I think it's really only useful for some bump types in any case. The
ratio bumps are really point-in-time values -- they represent "right
this very moment" (or "late last night," I guess). Threshold bumps
don't attempt to take scale into account, just that some line was
crossed. For circs this year or holds this month, or similar, age
scaling (probably a better term than just "aging") of each event's
relevance should be useful.

Kathy,
Have you considered allowing an aging parameter for some
bumps, so that
newer data toward the near end of the horizon is considered
more important?
For instance, spikes in circulation might have a larger short
term effect
on relevance, but over time, while still being factored into
relevance,
would be less important though still considered in the bump
logic. I ask
because I have a simple algorithm I'm using in another
project, to be
debuted at the conference, that may be portable to this work.

Hi all,
MassLNC is working with our partners at MVLC to develop an
activity metric
(aka popularity metric) that will allow sites to rank more
popular items a
little higher in search results than items that don't see
as much activity.
I've raised this idea on the list before. Although
Evergreen allows sites
to adjust relevancy based on the appearance of keywords in
certain fields,
which is highly useful, our hope is that this additional
functionality will
lead to further improvement when ranking results by relevance.
As an example, if a user were conducting a keyword search
on "abraham
lincoln," there are many titles in most US libraries
where the words
"abraham lincoln" show up in the title. There would be no
way to tease out
the titles that are getting the most attention by readers.
In fact, a title
like "Team of Rivals" ranks very low in our search results
even though
there is a high likelihood it is the title the patron is
seeking. By
applying a metric based on activity, we might be able to
see those
more-recently popular titles floating higher in the search
results list.
I would like to share MVLC's proposal outlining the
details for
implementing this project. The proposal is available at
http://masslnc.cwmars.org/**node/2757<http://masslnc.cwmars.org/node/2757>.
It provides a lot of flexibility in allowing sites to
define what "high
activity" means to them. Circulation activity, holds
activity, total
copies, and publication age/bib record age can all be used
as an activity
metric.
If you have any feedback or questions, feel free to let us
know.
Kathy
