SIREn N 元组结果

Question

是否可以

在SIREn中使用SolrDocument中的N元组值（按名称）？我想在没有响应字符串正则表达式的情况下解析查询结果。

像这样：

SolrDocument.getField("ntriple","name"); // get "Jim Maple" value for '<http:/example.org/schema/name> predicate

更多详情：

//N-Tuple from the IndexQueryNTriple.java file
 private final String[] doc1 = 
 { "http:/example.org/person/jim",
 "<http:/example.org/person/jim> <http:/example.org/schema/type> <http:/example.org
  /schema/Person> .n" + 
  "<http:/example.org/person/jim> <http:/example.org/schema/name> "Jim Maple" .n" 
 };
 final SolrInputDocument document1 = new SolrInputDocument();
document1.addField("url", doc1[0]);
document1.addField("ntriple", doc1[1]);
add(document1); 
final SolrQuery query2 = new SolrQuery();
query2.setQueryType("siren");
query2.set(SirenParams.NQ, "* <name> 'john AND gartner'"); // ntriple query
final QueryResponse response2 = server.query(query2);
for (SolrDocument d : response2.getResults()) {
///?????? want to get 'name' value from the long N-Triple string with ALL values
 d.getField("ntriple","name"); // get "Jim Maple" value
}

Answer 1

我找到了NxParser库来解析所需的N元组。

Answer 2

不幸的是，

NxParser对它可以解析的三元组的格式有一些限制
