Document ranking strategy for P2P file sharing system -


Recently, I found work to create a P2P file sharing system.

A requirement: The system should have a document ranking algorithm so that it can help users find more valuable files.

Many strategies can be useful:

  • User

  • Documents containing some key words are highly ranked

  • The manager may

  • More file was downloaded, it would get higher rank.

Do you know any other strategies or methods suitable too? Or is there a real world example?

I have to go with a combination of 1 and 4 but giving robustness to the users, though in the algorithm Users want to give more weight rather than ranking, because the download only indicates how often it was not downloaded, how useful it was to the user. The problem of compelling the user to give a ranking is that they can not give a ranking before downloading the file, because they do not know its contents without getting it.

If it is a system for which users need to login, you can submit them to some types of communication or to rate some files they have downloaded earlier, therefore Nothing is compelled to give them an option if they choose to not rank in a file, assuming that as a state of zero or depending on your needs Ignore it.
