Re: no frames?/maybe a visual synopsis

The broadest definition of graph hails from category theory, which is now also used to model quantum physics, and any models for (high energy) physics, (bio)chemistry, genomics, neuroscience, nano scale technologies in materials science and engineering, quantum computing circuits etc.

And the category theory graphs can be used for both causal and non causal representations. So in a sense the definition given by Dave is a SPECIAL case.
Exciting new research in neuroscience shows that cognitive processes in the brain and more specifically consciousness mirror quantum processes and that knowledge representation in the sense of quantum computing better describes and more closely resembles the functioning of our cognitive processes and consciousness.
Thus graphs in quantum computing are probably better suited for formalizing knowledge representation than current computer science.

 I appreciate the many definitions for knowledge graph, but for me, a simpler and more appealing definition is:

A knowledge graph is a network of concepts and properties that can be used to represent both data and data models.

That is broad enough to cover a broad range of techniques including RDF, Property Graphs and Chunks.  It also avoids limiting knowledge graphs to graphs with formal semantics. Dictionary definitions of “knowledge” include:

a) the fact or condition of knowing something with familiarity gained through experience or association
b) acquaintance with or understanding of a science, art, or technique
c) the fact or condition of being aware of something


d) the range of one's information or understanding
e) the sum of what is known : the body of truth, information, and principles acquired by humankind

Which seems pretty good to me.  Knowledge needs to be good enough to guide actions rather than having to be formally correct. Scientific theories are judged to be useful if their predictions agree with experimental observations.
