The Semantic Web Rule Language is a way to let computers understand what kind of data you have and how it should be used. It is a way to give instructions to computers in a language they can understand so they can help us make decisions. For instance, if we had a website about cats and wanted the computer to tell us which cats have long fur, then we could use the Semantic Web Rule Language to tell the computer which pieces of information it needs to look for and how to use them. In this way, instead of just relying on humans to find the information, the computer can do the work for us.
