That's the common parlance.<br /><br />I just don't see what the difference is, from a back-end, technical standpoint, between implicit and explicit. Well, other than what I've heard about search engines treating personalization more like group personalization, i.e. lumping you in automatically with similar-clicking and similar-querying people, so as to overcome the sparsity/cold start problem. <br /><br />So is that it? Is that the difference? In (implicit) personalization, it's more group-personal than it is perfectly-tailored-personal? <br /><br />Explicit personalization is perfect tailoring.jeremyhttp://irgupf.comnoreply@blogger.comtag:blogger.com,1999:blog-6569681.post-84715942307538465992009-12-08T10:58:07.108-08:002009-12-08T10:58:07.108-08:00I would suggest that personalization happens when ...I would suggest that personalization happens when the search results are modified from their generic form to suit the needs of the user looking at them, whether this modification is done automatically by the system (from information gathered over time), or explicitly when the user indicates what is and what is not relevant to them.François Schiettecattehttps://www.blogger.com/profile/01490974564731692816noreply@blogger.comtag:blogger.com,1999:blog-6569681.post-87236328733366600312009-12-08T10:30:04.058-08:002009-12-08T10:30:04.058-08:00Hi, Jeremy.

Both are types of personalization, I'd think.<br /><br />It's a little hard to know where to draw the line, but I wouldn't call faceted search personalization. It doesn't use history other than keeping previous state for building up a complex search query, so I wouldn't label that personalization.<br /><br />Why, what do you think?Greg Lindenhttps://www.blogger.com/profile/09216403000599463072noreply@blogger.comtag:blogger.com,1999:blog-6569681.post-80205090074024846362009-12-08T10:01:41.672-08:002009-12-08T10:01:41.672-08:00At some point, to get further improvements, Google...<i>At some point, to get further improvements, Google has to customize relevance to each person's definition of relevance. When you do that, you have personalized search.</i><br /><br />Also, when you allow an individual to explicitly say what is and isn't relevant to them, does that also mean you have personalized search? Or is search only personalized when there is an implicit, inference-laden interaction?jeremyhttp://irgupf.comnoreply@blogger.com
