Score calculations are performed in as many as six places (see the API),
but the main parts are indeed in distributeScoreToOutlink() and
updateDbScore().

Hi there,

I wonder which nutch/bin/ command call or which java in nutch 08 could do
the similar thing as org.apache.nutch.tools.LinkAnalysisTool did in nutch
07, which will iteratively caculate page score for each url.

thanks,

does nutch implement page ranking

2006-01-26 Thread Raghavendra Prabhu
Hi Guys

Does nutch have page ranking system in place

That is if contents of a url point to some other page

Whether that page has preference and does it come first

Is this done even while doing a crawl in nutch-0.7


I am not sure whether this feature is there as i can see boost factor for
urls

Can people tell me what is happening behind the scene?

Hello,

I have just installed, test crawled and then tried out search. Search
result page gives an option called  explain. Score Explanation, yes
I like to know a bit more about the ranking systems innerworkings. I
would be very glad if someone could point me to some documentation.
