如何使用Sparql包含来匹配相似的字符串?

Maa*_*mon 1 sparql triplestore stardog

我正在尝试在同义词库中的dbpedia中获取一些定义。

尽管可以找到带有与我的国家匹配的标签的国家,但我并没有全部获得。因此,我尝试将类似标签与包含匹配,但它不起作用。

知道为什么。

SELECT distinct ?idbcountry ?label ?labelDb ?def

WHERE {

            ?idbcountry a skos:Concept .
            ?idbcountry rdfs:label ?label .
            ?idbcountry skos:inScheme iadb:IdBCountries .
            FILTER(lang(?label) = "en") 

    Service <http://dbpedia.org/sparql> {
                ?s a <http://dbpedia.org/ontology/Country> .
                ?s rdfs:label ?labelDb .
                FILTER(CONTAINS (?labelDb, ?label)).
                ?s rdfs:comment ?def .  
                FILTER(lang(?def) = "en") .
                FILTER(lang(?labelDb) = "en") .
    }}

有效的确切匹配查询如下:

SELECT distinct ?idbcountry ?label ?def

WHERE {

            ?idbcountry a skos:Concept .
            ?idbcountry rdfs:label ?label .
            ?idbcountry skos:inScheme iadb:IdBCountries .
            FILTER(lang(?label) = "en") 

    Service <http://dbpedia.org/sparql> {
                ?s a <http://dbpedia.org/ontology/Country> .
                ?s rdfs:label ?label .
                ?s rdfs:comment ?def
                FILTER(lang(?def) = "en")
    }
}

如果不查看您的数据,我们将无法知道您的查询为什么不起作用。但是,使用包含非常简单。这只是contains(string,substring)的问题。正如Jeen所说,在不知道您的数据是什么样的情况下,我们无法重现您的问题,但这是一个包含的示例作用:

select distinct ?country ?label {
  ?country a dbpedia-owl:Country ;       #-- select countries
           rdfs:label ?label .           #-- and get labels
  filter langMatches(lang(?label),"en")  #-- but only English labels
  filter contains(?label,"land")         #-- containing "land"
}
