Concepts

Ok, so what is a concept?

Fundamentally, a concept is a thing or an idea*. One way to think of a concept is as a noun.

For example, let’s say you’re a big music fan, and you travel to a lot of music festivals all over the world. You want to create a knowledge graph to keep track of all of the festivals you visit and the towns they are in. One concept in your knowledge graph might be a Music Festival. Another might be a City:

The level of granularity you decide to use for your concepts is entirely up to you. Perhaps you attend other Events throughout the year, not just music festivals, and you want to keep track of those as well. Some of these events take place in the desert, so you want to define something more abstract than a city:

Of course, you may decide to pick something now and then rename it in the future as you develop your knowledge graph. You may also decide to keep both levels of granularity and connect them later through Specialization relationships.

*If you are coming from the OWL world, a concept is synonymous with a Class.
