DBPedia query to extract all attributes from all the smartphones present in dbpedia

Question

Is it possible to make a query to extract all the attributes from all the smartphones present in DBPedia?

Answer 1

It depends what exactly you need. You basically need to take "all x with type smartphone" and then you need to get everything about that x.

select distinct * where {
 ?phone dbpedia-owl:type|dbpprop:type dbpedia:Smartphone.
 ?phone ?x ?y
} 

For example, for getting the CPU, you can write:

select distinct * where {
     ?phone dbpedia-owl:type|dbpprop:type dbpedia:Smartphone.
     ?phone dbpprop:cpu ?cpu.
} 

Because if you look at Iphone 5, you will see that there is a CPU property defined. However, for brands it becomes more difficult. Some of the phone have developer defined (look at Iphone 3G), but other such as iPhone 5 has brand, or some have manufacturer, and some might have none. So basically you need to decide which one is it that you are looking for:

select distinct * where {
     ?phone dbpedia-owl:type|dbpprop:type dbpedia:Smartphone.
     ?phone dbpprop:cpu ?cpu.
     optional { ?phone dbpprop:manufacturer ?developer. }
}
