Information filtering system

An information filtering system is like a person who decides what you get to see. It looks at a lot of different pieces of information and decides what things are important to show you and what things are not. For example, a websites can use an information filtering system to show you only the articles about dogs if you search for ‘dogs’. The system looks at different things, like the title, description, and keywords from each article, and then decides which ones to show you first.
