Well, the Wikipedia article mentioned in the comments is quite theoretic. It starts with terms such as knowledge that need a few explanations. I take a deep breath and try to explain a few things... 1. What exactly is a Semantic Wiki? To make things simple, you probably know what...

inheritance,graph,compiler-construction,semantics
Consider the following two classes: class A extends B {} class B extends A {} In some languages, most notably C++, the above would be illegal because you can't refer to B before its declaration and you can't inherit from a class that has only been forward-declared. So in such...
Swift: Default property vs setting in initializer
swift,methods,properties,semantics
The only downside is that default property values are set every time an instance of the object is created, even if a property is subsequently overwritten in one or more initializers. This probably isn't an issue if you're just assigning default numeric values, but if there's a class that is...

Understanding Operational semantics
Every operational semantics is different and the question specifies no context, so I can only guess at the answer. I would parse if b then c; w else skip as if b then {c; w} else skip, that is, the second interpretation from the question. The derivation seems to be...
Protege Equivalent to query
sparql,semantics,semantic-web,protege4
This is a bit complicated, but if you look into the ontology everything that is defined as a :MealCourse is an owl:equivalentClass, so you need to first find all owl:equivalentClass and then if you look into the result you will see that they are made of owl:intersectionOf parts. Then you...
