Question

例如：

示例RDF字符串。

＆LT; Tom_Wilkinson_（演员）GT; ＆LT; actedIn＆GT; “In_the_Bedroom”，“The_Patriot_（2000_film）”，“Black_Knight_（电影）”，“The_Last_Kiss”，“Cassandras_Dream”; ＆LT; bornOnDate＆GT; “1948年12月12日”; ＆LT; isCalled＆GT; “Tom Wilkinson（Schauspieler）”，“טוםוילקינסון”，“トム·ウィルキンソン”，“Tom Wilkinson”，“וםוילקינסון”，“ム·ウィルキンソン”;

给定字符串的三元组 -

<Tom_Wilkinson_(actor)> <actedIn> "In_the_Bedroom"     
<Tom_Wilkinson_(actor)> <actedIn> "The_Patriot_(2000_film)" 
<Tom_Wilkinson_(actor)> <actedIn> "Black_Knight_(film)" 
<Tom_Wilkinson_(actor)> <actedIn> "The_Last_Kiss" 
<Tom_Wilkinson_(actor)> <actedIn> "Cassandras_Dream"
<Tom_Wilkinson_(actor)> <bornOnDate> "1948-12-12"
<Tom_Wilkinson_(actor)> <isCalled> "Tom Wilkinson (Schauspieler)"

注意 - 对象之间可以有空格。比方说“Tom Wilkinson（Schauspieler）”是一个包含空格的对象。

Answer 1

您提供的输入实际上已经是某些RDF的Turtle（或N3）序列化。它的格式通常是这样的，指定了一些@base：

@base <http://stackoverflow.com/q/23192184/1281433> .

<Tom_Wilkinson_(actor)> <actedIn> "In_the_Bedroom" , "The_Patriot_(2000_film)" ,
                                  "Black_Knight_(film)" , "The_Last_Kiss" ,
                                  "Cassandras_Dream";
                        <bornOnDate> "1948-12-12";
                        <isCalled> "Tom Wilkinson (Schauspieler)" ,
                                   "טום וילקינסון" , "トム・ウィルキンソン" ,
                                   "Tom Wilkinson" , "ום וילקינסון" ,
                                   "ム・ウィルキンソン" .

如果添加适当的@base声明，则可以使用任何可以读取Turtle并在N-Triples中序列化的库来读取输入并写入输出。例如，使用Jena的rdfcat，您可以转换为多种不同的格式，包括N-Triples：

$ rdfcat -out N-TRIPLES input.ttl

<http://stackoverflow.com/q/23192184/Tom_Wilkinson_(actor)> <http://stackoverflow.com/q/23192184/isCalled> "トム・ウィルキンソン" .

<http://stackoverflow.com/q/23192184/Tom_Wilkinson_(actor)> <http://stackoverflow.com/q/23192184/actedIn> "The_Last_Kiss" .
<http://stackoverflow.com/q/23192184/Tom_Wilkinson_(actor)> <http://stackoverflow.com/q/23192184/bornOnDate> "1948-12-12" .
<http://stackoverflow.com/q/23192184/Tom_Wilkinson_(actor)> <http://stackoverflow.com/q/23192184/actedIn> "The_Patriot_(2000_film)" .
<http://stackoverflow.com/q/23192184/Tom_Wilkinson_(actor)> <http://stackoverflow.com/q/23192184/actedIn> "In_the_Bedroom" .
<http://stackoverflow.com/q/23192184/Tom_Wilkinson_(actor)> <http://stackoverflow.com/q/23192184/isCalled> "Tom Wilkinson" .
<http://stackoverflow.com/q/23192184/Tom_Wilkinson_(actor)> <http://stackoverflow.com/q/23192184/actedIn> "Cassandras_Dream" .

由于您使用Python标记了这一点，您可能会发现RDFlib比Jena更有用，但这里真正的问题应该是如何进行转换，而不是库请求（因为库请求不在于堆栈主题）溢出）。

Answer 2

尝试使用RDFLib。看起来他们有examples on parsing ntriples

编辑：格式实际为n3。请参阅parse()

上的these docs

将一个字符串分成三元组（三个字段的元组），主语谓词和对象。
