Re: [OPEN-ILS-GENERAL] Activity metric for relevance
First off, I think this is a good enhancement and would be very helpful to all users particularly when searching a large database - a keyword search for Abraham Lincoln returns over 2400 hits when searching all of PINES.263 for one of the larger systems. Mike - would your algorithm mean that, with a title like Team of Rivals (which had an initial high rate of circulation and holds, then interest fell off to revive again with the movie), while it is first popular it rises in the search results, to fall as interest tapers, and then arises again, using older and newer interest data? That way it might bump above other titles that were popular in that interval more quickly than without the algorithm? Elaine _ J.

Re: [OPEN-ILS-GENERAL] Activity metric for relevance
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. 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.

Re: [OPEN-ILS-GENERAL] Activity metric for relevance
Something that took into consideration how current the circs/holds were could be valuable I think in reflecting a more ... natural effect that titles have in relevancy. For example, Gone Girl by Gillian Flynn. In the first 24 hours that the bib was in our system the total holds might be relatively small compared to some other titles during the last 6 months or a year. Now, by the end of a week the holds had skyrocketed and would show up well even in a search just for girl under the proposed approach. I think taking into consideration the timeliness of those weights would give a more natural reflection of the title rising to the top over the course of the week (and significantly higher that first day).

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. --miker Thomas Berezansky Merrimack Valley Library Consortium Quoting Mike Rylander mrylan...@gmail.com: 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?
