"These types of personalized PageRanks are virtually immune to manipulation by commercial interests.
For a page to get a high PageRank, it must convince an important page, or a lot of
non-important pages to link to it. At worst, you can have manipulation in the form of buying
advertisements(links) on important sites. But, this seems well under control since it costs money"
To me this reinforces that you should take seriously things like 50% bitcoin attacks. If bitcoins become valuable enough, someone will do it.
Will expire in about a year and three months!
And another paper by Page and Brin: http://infolab.stanford.edu/~backrub/google.html
I found a guy who works at Google, we should be all good, I just emailed him, let's see what he says.
I was slightly disappointed that this isn't what it says in the paper, or presumably your comment!
(Still no Ida why it was split when words are usually wrapped.)
I heard if you work for a company while also developing a startup depending on the contract the company can claim they own the startup - even if you were working on it at home with your computer you bought with your own money and off the clock for them.
I was a Stanford grad student in the 1980s when these policies were still being worked out. There were cases of grad students being abused by the commercial interests of their professors before the university clamped down. These abuses included postponing the publication of results which could delay graduation or an academic career. Now profs and students can only spend 20% of their time on commercial interest or should take a leave of absence and leave Stanford facilities if they want to work more. The just retired Stanford President did such when creating his RISC computer company MIPS. Also you can only delay publication one year.
Stanford didn't own Google, they owned the PageRank patent, which they licensed to Google in return for equity.
Undergraduate students generally are not employed by the university and are not required to sign IAAs, so they keep the rights to their own inventions. (Though there can be some tricky situations where significant university resources are used.)
Do they get paid to do this sort of stuff too? I know I heard of people working in like the library to help pay down their loans. Just never really thought of colleges owning IP. So just a bit of a surprise to me.
Undergraduate students get scholarships for doing research, grad students do research as part of their studies and professors are usually researchers as well.
Besides that, time spent on page and social signals such as likes and tweets probably count for more than links. A crappy spam site would be disregarded pretty soon, because people would immediately bounce back to Google and try other sites.
"The fact that in-degree features outperform PageRank under all measures is quite surprising. A possible explanation is that link-spammers have been targeting the published PageRank algorithm for many years, and that this has led to anomalies in the web graph that affect PageRank."
It works less well than it used to, but its never used in isolation. Used in isolation its a pretty good porn detector.
I believe that each and every technology that successfully manages to index the web in a new and useful way will further diminish the value of the web.
How about when I measure a stick using a ruler?
I just googled for some implementations like this one in Go: https://github.com/dcadenas/pagerank
