Explain why semantic object attributes are called paired attributes
What will be an ideal response?
Semantic object attributes are used to indicate a relationship between two semantic objects. When there is a relationship between two objects, the objects are placed as object attributes within each other. They are called "paired attributes" because relationships are by definition two definition two-way relationships. Thus, when a semantic object is placed in another semantic object as an object attribute, a corresponding object attribute representing the second object is required in the first semantic object.
