sparql - 在 sparql 中搜索部分匹配的字符串

Question

假设我有一个如下所示的 RDF 图：

entity1 [
    title [ obect1.svg]       
    description [
         "This is sentence 1.  This is sentence 2." ]
         ] .
entity2 [
    title [ obect2.svg]       
    description [
         "This is sentence 3.  This is sentence 4." ]
].
entity3 [
    title [ obect3.svg]       
    description [
         "This is sentence 1.  This is sentence 4." ]
] .

我将如何编写查询来查找这是第 2 句？
