Internet Content Filtering | |
| Keywords: | topic detection, web content analysis, improper content |
| Description: | Nowadays, Internet has become a popular information medium. It opens new opportunities of presenting information by means of the links and this opportunity is widely used for information search and perception. More and more people use Internet for work and free time spending. But the rapid growth of Internet and public access causes some issues. There is no restriction, everybody can publish on Internet anything and everybody can see it. Many sites in Internet contain indecent, violent and generally unseemly content. Parents worry that their children might be accosted by pornography, violence, extremism or pedophiles. In cyberspace, people can change their personality very easily and they can be whoever they want to be. It is very difficult to trace the owners of unseemly web sites. There exist even servers containing especially unseemly or forbidden content. Our primary task is to detect these servers or individual sites in various languages. There exist many commercial applications for Internet content filtering using pre-classified web sites database. Our approach is to allow users to set their own level of exceptionability during web watching. Then we want to analyze stored exceptionable web sites (they usually contain links referring to next inappropriate sites) and to find servers containing most of these sites. The goal of this system is to facilitate the work of governmental institutions in preventing and combating Internet crime. Next usability is mainly in public institutions (schools, universities, libraries). |
