如何解决PLS 帮助修复 SPARQL 查询

下面的 SPARQL 查询会引发错误。怎么了？ Protege syay 在第 1 行，第 8 列，遇到“”（32）后有一个词法错误：“private”

private static ResultSet getСontNameFirst(OntModel model,string nameWord) { 
    String queryString = String.format(
    "PREFIX wordnet:<http://www.owl-ontologies.com/wordnet.owl#> " +
    "SELECT ?word " +
    "WHERE { " +
    " ?%s wordnet:?pre ?subject " +
    " { SELECT disTINCT ?pre WHERE { " +
    " ?word wordnet:?pre ?otherword " + "
    } }" +
    " OPTIONAL { ?%s wordnet:?pre ?word}" +
    "}",nameWord);
    QueryExecution qe = QueryExecutionFactory.create(query); 
    ResultSet results = qe.execSelect();
    return results;
}
