in thread Fuzzy matching to user's tastes?

The vector space search looks like it could possibly handle what I need, although if it keeps everything in-memory, it's going to eat up a ton of resources (it would have to parse the entire group of documents each and every time the script is run). Perhaps using the Storables method above along with this would be a good solution.

The other difficulty (and why the amazon-method would not work) is that this is an auction site. It is very unlikely that two people would ever purchase (ie, win) the same item with the exact same title. And because it's an auction site, those 5,000 or more items will not always be the same 5,000 items. In fact, the turnover rate would be in the hundreds-per-day.

Also, these "documents" would of course be contained in a database. I'm not sure how much that throws things off. I suspect it doesn't from my reading of the article you linked to.

    If you are worried about only one person getting any specific item, look at who bids instead. Then use some kind of classifier on the bidding patterns to find each user's k nearest neighbors for some k. When a user bids on something, message his neighbors (unless they've been messaged already).

[Corion]: No. It's just that I'm comparing the same output file twice, instead of comparing the output files of the two runs %-)
[Corion]: Lo and behold, running a program with the correct input files yields the correct (and expected) output. Yay me.
[1nickt]: Got a MacBook and am expected to develop directly on it, ironic given the recent thread about that.
[marto]: Corion, some not too serious issues with the kids, hopefully, other than that just dealing with commuting by car again in the winter, not much fun so far, and there's no real 'bad' weather yet :)
[marto]: 1nickt, glad to hear it, I'm sure you'll bring improvements to their stack in due course ;)
[1nickt]: Just trying to adjust to a new culture. Better doc than I am used to , but quite a bit more Agiley meta-bullshit; at least half a dozen meetings a week, strict "sprint" schedule etc. I'll adjust. And I hope to just switch off after the "scrum" each day at
[1nickt]: ... the end of the afternoon. marto How are you, snowed in? Mum and Dad expecting snow today in Surrey. (Have 5" on the ground here in NJ. And my son's high school in SOCal closed until after Xmas due to fires.)
[Corion]: 1nickt: In a sense the meta-bullshit might even be beneficial to you as you get to hear the cow-orkers talk (or not talk) about the issues you perceive. I think Agile is mostly about the meta ;)
[Corion]: 1nickt: On Sunday maybe 10cm of snow fell, and the airport closed, and the trains stopped running etc :) It always comes as a surprise that snow falls here during the winter...
[marto]: 1nickt, no snow, just some ice on the roads and the usual idiocy associated with humans and driving in less than ideal conditions
