Using this SPARQL end-point: http://dbpedia.org/sparql you can enter this query:
SELECT DISTINCT ?YA ?A ?YB ?B where {
?A dbo:influenced ?B.
?A a dbo:Philosopher.
?B a dbo:Philosopher.
?A dbo:birthYear ?YSA.
?B dbo:birthYear ?YSB.
BIND( SUBSTR( xsd:string(?YSA), 1, 4) AS ?YA )
BIND( SUBSTR( xsd:string(?YSB), 1, 4) AS ?YB )
} LIMIT 10000
which ...

There is dbp:iso3166code, but it seems it's not set for a lot of countries.

DBpedia (http://dbpedia.org/sparql) holds a static dataset, updated in batches roughly every 6-12 months. Changes made on Wikipedia will eventually show up here.
DBpedia-Live (http://live.dbpedia.org/sparql) holds a dynamic dataset, updated from the Wikipedia firehose on a near-constant basis. Changes made on Wikipedia generally show up here within hours ...

DBpedia
The answer provided by @svick will probably be most useful one in the long run, but for the time being dbp:iso3166code is unusable.
However, I noticed that (apparently) all the country pages are the targets of redirects of this kind:
dbr:ISO_3166-1:DO dbo:wikiPageRedirects dbr:Dominican_Republic
Therefore, I can extract ISO 3166-1 code like this:

First, I assume all NLP-related aspects are subtracted from your question.
DBpedia is considered as belonging to the Linguistic Linked Open Data Cloud (interactive SVG), but I'd suggest to try more specialized resources, e. g. RDF version of BabelNet.
One can't retrieve the whole list of English words with the number of meanings on the public endpoint.

<http://purl.org/linguistics/gold/hypernym> is a property from the GOLD linguistic ontology.

Your question shows <> which is not a valid property or wildcard.
You cannot use property variables (wildcards) in property paths.
So you need to understand the structure of how dct:subject and skos:broader are used, and exploit that. I happen to know that
dct:subject links pages to categories
skos:broader makes the category hierarchy
I should warn ...

Here below I'm using examples from comments to your previous question.
Linked Data Fragments
For simple queries, you could use Linked Data Fragments:
Query 1
Query 2
Add Accept: application/json header, if you need a JSON response.
SPARQL
For complex queries, you could use SPARQL.
For example, you don't need to know preliminarily, whether a resource ...

YAGO Demo page lists two possible ways:
Explore YAGO with our graph browser (YAGO3)
Explore YAGO with our ontology browser (YAGO2)
You can find what you need using query builder.
There also exists SPARQL endpoint.
