I'm not paranoid... April 19, 2010 8:05 AM   Subscribe

How does the "Related Questions" tool on Ask work?

My question (which I won't link too incase it comes across as trying to 'promote' it somehow) is about cameras, with the tags "camerasetup", "canon350d" and "canon550d".

One of the "related" questions is this one about some lass who was convinced (rightly or wrongly) that she was being bugged.

How does the related questions tool work, and what connected these two questions like this?

Stop looking at me like that... I'm just asking...

Related Questions uses a combination of tag and category data to look for likely matches. I think what you're actually seeing is the result of a very-low-information case, where your tags are all unique (hapex legomena! or googlemefitagsearchwhacks), and so all the matching engine has to work with is the category.

How it produced the five "technology" questions it did I don't know exactly, but the rest aren't any more related to your specific camera question than the paranoia one is. They're just less eye-catching in their unrelatedness.

I may be forgetting some third vector of comparison besides tags and category, but I don't know what. pb would know more.

Cool, thanks Cortex.

Thank you for taking the time to post this question. Since the mods linked the Ask server into to the US Department of Homeland Security's terrorist surveillance division network, its AI has been a bit tempermental. Occasionally, it takes it upon itself to warn surveillance subjects that they're being monitored by the federal government.

Of course... heh heh... that never really happens. This is what we get for giving computers a sense of humor.

Please disregard the "Related Questions" section below your post. Oh, and since the weather is getting a bit nicer, you might consider leaving your window shades open more often.


Oh, and there is no cabal hamburger stand.

As the person who answers real life email from real life paranoids as part of my job, this is only sort of funny.

Wait, so it doesn't do a DNA test on your question to determine which questions are its ancestors and descendants?

I heartily apologize in advance if you get any email from people who take that comment seriously.

Real mods don't forget the third vector of comparison.

I think that related AskMe probably came from the astral comparison vector. As such you'd need to ask meatbomb about the reasoning.

Just took a look to refresh my memory, and as cortex said it's based on tags and categories. Rare tag matches get a higher score. In the case of your question, there were no tag matches so the only match to use was category. In that case we also look at the number of favorites a question has. So in this case you're just seeing a random list of some highly favorited questions in the technology category.

Keep that up and all your Related Questions from now on will be about oozing sores and suchlike.

Well done, languagehat! You got cortex to reveal the third vector of comparison: presence of poster on "people who have pissed off the mods" list.

cortex: hapex legomena!

Thank you for making me look it up.
Kinda cool object to add to my word set.

Generally accepted references seem to spell it hapax, though.

Yeah, I'm shite for spelling.

You and me both. I went to check how I'd spelled it on the web page with the list of tags used only once on MeFi, and I did the heading one way and the actual text file the other.

I think we can safely blame the proximity to 'apex'. That and my total ignorance of Latin. But mostly the apex thing.

To say nothing of my Greek. Jesus, stop me before I kill again.

I would like to hear more about your Greek Jesus.

You, and you, and me three. Sucks when you typo your own username. I'm slowly getting over it though.

On the subject of spelling, it occurs to me that there's an interesting research project waiting in the wings for some linguist, looking at the influence of mobile devices with text prediction on average typo and misprediction rates on e.g. mefi over time.

I've been both committing and noticing more of these Cupertino-type errors lately since I've started hitting the site from iPhone and iPad (though I readily acknowledge that the big uptick in noticing is probably all me with the confirmation bias).

hapax legomenon, ἅπαξ λεγόμενον ... see also googlewhack.

Pity about the spelling, would have made for a great mnemonic: hapex is never a twin.
