A score file is a more advanced filter than a kill file. It
allows you to filter information gleaned from the USENET newsgroups to
determine whether it is spam or not.
When USENET members use a kill file, they're using a system that is basically designed around a yes or no answer on whether any particular post gets downloaded. A score file is a more advanced implementation of the same type of filter. A score file uses various criteria to assign a rank to a given posting. If that link is below a certain threshold, it is not downloaded. If it is above a certain threshold, it is downloaded. This is a very familiar concept to anybody who is used to using a spam filter.
The Criteria
The criteria used for score files gets very complex. In fact, in the spirit of open source development, many users of these filtering mechanisms share their score files on USENET newsgroups so they can all benefit from the refinements that they make.
The criteria used for a score file will typically vary by the user. For example, somebody who is a member of the scientific group may know of a particular member who tends to post information that is erroneous or that is simply designed to troll. This information may contain characteristic phrases. The criteria for the score file could be adapted to deduct points from posts if they contain those characteristic phrases. This would mean that, if the poster who puts up the annoying messages happens to post something interesting, their post wouldn't be automatically disqualified from being downloaded simply because it had their name attached to it as it would in the case of a kill file.
The score file is more precise and less likely to delete information that the user may actually want. This is one of the reasons that they are very popular. This concept is also used on the spam filters that protect e-mail servers. For the sake of example, we can use something that would apply to both spam e-mails and spam USENET posts to explain how the scoring might work.
Imagine a post or an e-mail that contains information about prescription drugs. The information gives various prices for prescription drugs from various pharmacies and recommends that the recipient purchase their prescription drugs from a particular pharmacy. On the face of it, this looks like pure spam. Now, however, add the qualifier that the message was sent from a doctor that the recipient actually knows. The recipient can set their score file to acknowledge messages sent from unknown sender and to give them a very high score. This would mean that all of the detrimental effects on the score that would no doubt be observed because of the content of the message would be negated by the centers good reputation. This is an example of how a score file can be used to make sure that information that is actually desired doesn't get removed from the information stream because it contains terms that may trigger a kill file.
