semantics - Searching semantically tagged documents in MarkLogic -


can 1 please point me simple examples of semantic tagging , querying semantically tagged documents in marklogic?

i new in area,so beginner level examples do.

when "semantically tagged" mean regular xml documents happen have triples in them? discussion , examples @ http://docs.marklogic.com/guide/semantics/embedded pretty that.

start enabling triple index in database. insert test doc. xml, sem:triple element represents semantic fact.

xdmp:document-insert(   'test.xml',   <test>     <source>ap newswire</source>     <sem:triple date="1972-02-21" confidence="100">       <sem:subject>http://example.org/news/nixon</sem:subject>       <sem:predicate>http://example.org/wentto</sem:predicate>       <sem:object>china</sem:object>     </sem:triple>   </test>) 

then query it. example query pretty complicated. understand what's going on i'd insert variations on sample document, using different uris instead of test.xml, , see how various query terms match up. try using sparql component, without cts query. try cts:search no sparql, cts:query.

xquery version "1.0-ml"; import module namespace sem = "http://marklogic.com/semantics"    @ "/marklogic/semantics.xqy"; sem:sparql('   select ?country   { <http://example.org/news/nixon> <http://example.org/wentto> ?country   }   ',  (),  (),  cts:and-query((    cts:path-range-query( "//sem:triple/@confidence", ">", 80) ,    cts:path-range-query( "//sem:triple/@date", "<",     xs:date("1974-01-01")),    cts:or-query((      cts:element-value-query( xs:qname("source"), "ap newswire"),      cts:element-value-query( xs:qname("source"), "bbc"))))))
