不知道爲什麼,這不是張貼@JoshuaTaylor作爲一個答案,但添加@ JoshuaTaylor的過濾器來查詢是您所要求的內容:
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX dc: <http://purl.org/dc/terms/>
PREFIX movie: <http://data.linkedmdb.org/resource/movie/>
SELECT ?title ?date ?director ?imdbID
WHERE {
?film foaf:page ?imdbID.
?film dc:title ?title.
?film dc:date ?date .
?film movie:director ?directorURI.
?directorURI rdfs:label ?director .
FILTER(regex(str(?imdbID), "www.imdb.com"))
}
將返回:

如果你想讓它不區分大小寫,你可以使用如下標誌:
FILTER(regex(str(?imdbID), "www.IMDB.com", "i")
如果你想了解更多關於過濾器的信息,請看3.1 Restricting the Values of Strings。
在[排除基於URI前綴的DBpedia SPARQL查詢結果](http://stackoverflow.com/q/19044871/1281433)中的技術是否適合您?有了它,你只需'過濾(strstarts(str(?imdbID),「http://imdb.com」))',我想。 –
哦,linkedMDB端點不支持SPARQL 1.1,所以你必須使用正則表達式,它顯示:'filter(regex(str(?imdbID),「^ http://www.imdb.com」)) '。該方法也列在其他問題中。 –
