What many here seem to miss is that this looks at coincidences in the timing of searches. This is not "within-subject": it's not that people-who-search-for-x-also-search-for-y. Rather, it's WHEN-people-search-x-other-people-are-also-likely-to-search-y .
That being the case, can anyone come up with an explanation for this? http://correlate.googlelabs.com/search?e=accident&t=weekly http://correlate.googlelabs.com/search?e=accident&t=week...
- hammock 15y agoNot hard, dude. You should know that the people-who-search-for-x-also-search-for-y is inherently built into WHEN-people-search-x-other-people-are-also-likely-to-search-y, since people who are searching on "accident" and not finding what they want aren't likely to wait 4 weeks before trying "fatal accident" - instead they are going to immediately try it, meaning that WHEN that person searches x it is also likely he will search for y. The other (non-mutually exclusive) explanation here is that different people are searching for the same thing (e.g. a news item they saw on TV about a recent car accident) but using different terms to do it (e.g. accident, car accident, fatal accident).

- leot 15y agoThe pattern looks more interesting than simply that. Multiple semantically related terms are correlated with "accident". And, strangely, "fatal accident" is not correlated very much with any of those other semantically related terms. Further, there are bunches of other queries that you might imagine "summer-ness" could also drive (air conditioners, heat rash, e.g.), but which it doesn't.
