the logging for example can be done via Javascript, e.g.

http://sourceforge.net/apps/mediawiki/easyrec/index.php?title=JavaScript_API_v0.95

whereas these requests are then sent to "Boost" instead the CMS, or the 
CMS can log the relevant requests by itself, e.g. using log4j and 
logging something like

4317126 2011-04-28 10:23:45,899 [http-8080-Processor23] INFO  Access  -

t:overview%2CAbout+Lenya

whereas the most important parts re personalized interest analysis are, e.g.

Tags (t): t:overview,About Lenya
Unique cookie ID (c): c:YA-1302509054838

I guess you mean for example if a user types "Java" as a search term, 
and if the user is mostly interested in
programming languages, then the results will be about Java as 
programming language, whereas if the user
is not interested in programming language, then the results will be 
about Java Island or Java coffee, right?

Well, the CMS would call the API of "Boost", e.g. via SOAP it could look 
like:

Request to "Boost":
GET /boost/user-interests/cookie-id/YA-1299502385092
GET /boost/user-interest/user-id/marc

Response by "Boost"
<?xml version="1.0"?>

<user-interests cookie-id="YA-1299502385092" user-id="IF_AVAILABLE">
<interest weight="10">Jaguar</interest>
<interest weight="2">VW</interest>
</user-interests>

(Comment: Higher weight values are considered more important)

which means the Lenya personalization module can then use the above user 
interests to generate
a personalized response. The flow is as follows:


Browser/User -> Lenya CMS -> Boost -> Lenya CMS -> Browser/User

IIRC it also uses log4j, but not specifically for access logging, but as 
I tried to point out above, Lenya
doesn't have to do this by itself, but I guess the most simple of 
integrating this is by adding
the Javascript code to each page (see above or similar as Google analytics).
