You need to try this out for yourself before reading the rest of this post.
Go ahead, I’ll wait…, …, …, ok.
To some extent this “aggregation” may reflect on the sort of questions we ask users about topic maps.
It’s possible to aggregate data about anything number of things. But even if you could, would you want to?
Take the “aggregation” for Birmingham, UK, this evening. One of the components informed me a choir director was arrested for rape. Concerns the choir director a good bit but why it would interest me?
Isn’t that the problem of aggregation? The definition of “useful” aggregation varies from person to person, even task to task.
Try London while you are at the site. There is a Slightly Unhappier/Significantly Unhappier, “Mood” indicator. It has what turns out to be a “count down” timer, for the next reset on the indicator.
I thought the changing count reflected people becoming more and more unhappy.
Looked like London was going to “flatline” while I was watching.
Fortunately turned out to not be the case.
There are dangers to personalization but aggregation without relevance just pumps up the noise.
Not sure that helps either.
