在SPARQL

Question

假設部分匹配搜索字符串我有一個RDF圖看起來像以下：

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." ] 
] . 

我將如何編寫一個查詢發現這是句2？
