7.1 Nuts and bolts

The following pages

In the following pages we will demonstrate how (a small part of) a text can be represented in Prolog+CG. Through an example, we demonstrate:

• how the knowledge base can be organized
• how the text is represented in graphs
• how the semantics of the domain is accounted for in an ontology
• how queries can be constructed and
• how computational operations can be used to reason over the knowledge base.

The example of Macbeth

In the following, we will represent a few sentences and expressions from the play "Macbeth" by William Shakespeare.

Consider the following quotes:

Macbeth: "Is that a dagger which I see before me?" (2.1.31)
Macbeth: "I'll fight, till from my bones my flesh be hacked." (5.3.34)

These examples are available as macbeth.plgCG and macbeth2.plgCG in the AAU directory.

Next, we describe how to organize the knowledge base.
