Pagerank Patent

This is an absolute must read for the advanced user:
http://www.searchen.com/forum/t66-p...thm-patent.html

This seems to be a patent by Google (mentioned as "search engine 125") for the algorithm(s) that make up pagerank and document weighing technology.

This also backsup my previous belief that actual content freshness is used to calculate pagerank.

This is huge, imho and expands on the original patent information provided by randfish.


I don't think this has anything to do with Page Rank, this is exclusive to document scoring for ranking.

this line is:

54. A method for ranking a linked document, comprising: determining an age of linkage data associated with the linked document; and ranking the linked document based on a decaying function of the age of the linkage data.

55. The method of claim 54, wherein the linkage data includes at least one link.

56. The method of claim 54, wherein the linkage data includes anchor text.

57. The method of claim 54, wherein the linkage data includes a rank based, at least in part, on links and anchor text provided by one or more linking documents and related to the linked document.


Infers deep linking (any linking) is important from unique IP's

This line I believe addresses specifically the co-op style advertising networks

23. The method of claim 22, wherein the behavior of links relate to at least one of appearance and disappearance of one or more links pointing to the document

25. The method of claim 22, wherein the determining behavior of links associated with the document includes monitoring at least one of time-varying behavior of links associated with the document, how many links associated with the document appear or disappear during a time period, and whether there is a trend toward appearance of new links associated with the document versus disappearance of existing links associated with the document.

63. The method of claim 62, wherein adjusting the ranking includes penalizing the ranking if the link churn is above a threshold.

Overall, the document appears more to address what the sandbox is rather than addressing anything to do with page rank itself.

This is...huge huge huge huge...... good stuff.

Huge....

22. The method of claim 1, wherein the one or more types of history data includes information relating to behavior of links over time; and wherein the generating a score includes: determining behavior of links associated with the document, and scoring the document based, at least in part, on the behavior of links associated with the document.

26. The method of claim 1, wherein the one or more types of history data includes information relating to freshness of links; and wherein the generating a score includes: determining freshness of links associated with the document, assigning weights to the links based on the determined freshness, and scoring the document based, at least in part, on the weights assigned to the links associated with the document.

27. The method of claim 26, wherein the freshness of a link associated with the document is based on at least one of a date of appearance of the link, a date of a change to the link, a date of appearance of anchor text associated with the link, a date of a change to anchor text associated with the link, a date of appearance of a linking document containing the link, and a date of a change to a linking document containing the link.

28. The method of claim 26, wherein the weight assigned to a link is based on at least one of how much a document containing the link is trusted, how authoritative a document containing the link is, and a freshness of a document containing the link.

29. The method of claim 26, wherein the scoring the document includes: determining an age of each link pointing to the document, determining an age distribution associated with the links based on the ages of the links, and scoring the document based, at least in part, on the age distribution associated with the links.

30. The method of claim 1, wherein the one or more types of history data includes information relating to a manner in which anchor text changes over time; and wherein the generating a score includes: identifying a change in anchor text associated with a link to the document, and scoring the document based, at least in part, on the change in anchor text associated with a link to the document.


Lordie.... someone else can correct me if I am wrong, but this is like the "holy grail"..... lmbo! Sorry..... I just peed myself reading it....thank god I wear depends (Hey, Wit suggested it) so I don't have to get up to go potty!

Here is your PR document I believe (?) - http://appft1.uspto.gov/netacgi/nph...5999&RS=6285999

BTW....can someone pull the images?

Interesting search as well http://appft1.uspto.gov/netacgi/nph...1&Query=6285999

Can't wait to read this thread tomorrow!

I share your enthusiasm with this data.... I knew that others would see this as detramental and imperitive data....

As far as the pagerank suggestion, I just have this feeling that the overall end factor will control how all of these actions will eventually build a "score" and that score should not be similated in anyway..

I think the final "score" will become what is now known to us as pagerank.

Here is a post to the link to the PDF file. It contains the images. This was posted by x3nos when Phoenix started a thread on this a while back in the Google Opt. forum. Enjoy!

Wellllll Where the H**L Was I????? Sigh.......I tell ya...snooooooze ya looooooose. What a bunch of time I wasted... Thanks for the link! Good Stuff and dang sure could have used this last year...lol

Yeah, this whole thing came out at the end of March. I'm surprised you missed it gchaney.

Not bad to be reminded though. Especially since some of us seem to have been in doze mode back then

Thanks clasione for getting it on your forum and reminding us... ;)

I knew about it then and i just scanned through it paying no attention to any of it.

I also choose to ignore it now.

I nomally devour information like that but i this case i have decided that my ignorance is bliss this time.

Doesent seem to be affecting my income that i have put my head in the sand on this one.

This is a very important document! Thanks clasione!

Is it me, or does 60 seem to contradict 59?

twins.fan

No, I don't think it contradicts. I think it compliments
BTW, Great thread clasione

Maybe I saw it and suffered from shock and permanent memory loss? Yeah...yeah...that's it.

Being at the top of all three major engines for a pretty completive phrase, I have a continues stream of webmasters who link to my site and send me an email asking for a link bank. Being the MSoB that I am, I do not oblige, and they normally remove their links in a week or two.
Does this mean I will start suffering?

If they are all strugglers, then chances are that their link to you isn't even picked up by the SEs
in the two weeks it's up

So no harm done - I guess.

God, I hope not! It can takes me as much as two weeks now to get around to responding.....Just not a huge priority for me. Most are long gone by then.
