What is content filtering?

Content filtering is an automated process of incoming mail classification such as spam or legitimate mail. SPAM is an unsolicited, undesirable unhealthy mail, often from "non-following" sources sent in bulk e-mails. Content filtering can take place on a mail computer, personal computer or both. If the content filtering is carried out on a home or office computer, the desire can be further classified by a legitimate mail for personal purposes.

Mailserver, which triggers a spam filter, has a built -in ability to refuse mail based on various parameters such as keywords, original addresses or other header information. Many mail servers run some type of content filtering software, but it is often not enough to keep spam at bay. Mailserver SPAM filters must be somewhat general, quite said to be responsible for the customer base.

Personal content filtering can be very specific. The most popular type of software to filter content useThe Bayesian method. In this case, the software that performs content filtering is "trained" to accept or reject the mail. This is referred to as "intelligent" content filtering. The software parameters are rejected based on the post office and performs statistical analysis at the incoming post office to see if there is a probability that the new mail is spam.

When the program goes wrong, it is easy for users to fix an error by accepting an event, such as clicking on the "Keep" button or moving mail to the accepted folder. Conversely, if SPAM slip, the "SPAM" or equivalent action button can fix the error. The program updates its parameters for future instances. Soon the program requires little or no user intervention.

The

Bayes method allows each user to customize the filtering of the content to his needs. What is spam for one person can be interesting forthe other. The intelligent content of filtering also allows the user to change its definition of spam.

For example, when buying specific online items, you might be interested in receiving bids or information. However, after purchasing, these offers may become annoying - especially when they still come a few weeks and months later. For local -start -launch software, the offers are initially accepted to accept offers and train software that rejects all such mail after purchases.

In addition to simply filtering up spam, advanced content filtering can also perform functions such as sorting legitimate incoming mail to various folders, copying of mail, or assigning some types of own colors. All family mail can be in red, while the newsletter subscription could be allocated green. With the view of colors you can find out what the e -mail is in the post office.

Function, functionality and efficiency of content filtering will depend on the program used. There are sebAlíčky content filtering veral available online.
