Defining Decision Tables for RDF Triple Processing

Suppose you have some data about relationships between family members:

And we want to implement some rules of the form:

if X is a parent of Y and Y has a sibling Z then X is a parent of Z

Which will deduce some new parent relationships (shown in red):

We could write a decision table like this (BizVR Examples\Ontologies)

Which will produce these results:

You can also express the conditions more concisely as follows:

And the action section can be written like this:

This approach can be useful sometimes as it reveals more detail on the overall decision diagram:

This is most useful when

• the decision table contains a single rule, or
• the decision table contains multiple rules but the action is simply X (i.e. execute the expression in the left most column)
