dbpedia提取JSON [英] dbpedia extract JSON

问题描述

http://dbpedia.org/resource/Los_Angeles

您可以通过在您的HTTP请求中使用适当的头部以多种格式以编程方式请求这些数据。

例如，Accept：application / json将以JSON形式获得结果。

1。我该如何去检索JSON

2.因为我只需要筛选

a class =urihref =http://www.w3.org/2000/ 01 / rdf-schema＃label

用于我页面上的大约100个链接。什么是最好的解决方法

您可以检索JSON，而无需通过简单的请求创建特殊标头

• http://dbpedia.org /data/Los_Angeles.json

如果您只对 rdfs：label感兴趣 s，您可以通过使用模板请求URL来查询端点：

  http://dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=select*%7Bdbpedia%3ALos_Angeles+rdfs%3Alabel+%3Flabel%7D&format= json 
  

对应查询

  select * {dbpedia：Los_Angeles rdfs：label？label} 
  

SPARQL结果

生成JSON：<$ p

  {head：{link ：[]，vars：[label]}，
results：{distinct：false，ordered：true，bindings：[
 {label {type：literal，xml：lang：uk，value：\\\Л\\\о\\\с-\\\А\\\н\\\д\\\ж\\\е\\ \\ u043B\\\е\\\с}}，
 {label：{type：literal，xml：lang：vi，value：Los Angeles}} ，
 {label：{type：literal，xml：lang：zh，value：\\\洛\\\杉\\\矶}}，
 {label：{type：literal，xml：lang：ca，value：Los Angeles}}，
 {label：{type： literal，xml：lang：cs，value：洛杉矶}}，
 {label：{type：literal，xml：lang：德，价值：洛杉矶}}，
 {label：{type：literal，xml：lang：en，value：Los Angeles}}]}}

You can request this data programmatically in many formats by using the appropriate header in your HTTP request.
For example "Accept: application/json" will get you the results in JSON.
1. How do I go about retrieving the JSON
2. Since I have to filter only
a class="uri" href="http://www.w3.org/2000/01/rdf-schema#label"
for around 100 links on my page. What is the best way around it

解决方案

You can retrieve the JSON without having to create special headers by simpy requesting

• http://dbpedia.org/data/Los_Angeles.json

If you're only interested in the rdfs:labels of the entity, you might query the endpoint by using a template request URL:

http://dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=select*%7Bdbpedia%3ALos_Angeles+rdfs%3Alabel+%3Flabel%7D&format=json

which corresponds to the query

select*{dbpedia:Los_Angeles rdfs:label ?label}

SPARQL results

which generates the JSON:

{ "head": { "link": [], "vars": ["label"] },
  "results": { "distinct": false, "ordered": true, "bindings": [
    { "label": { "type": "literal", "xml:lang": "uk", "value": "\u041B\u043E\u0441-\u0410\u043D\u0434\u0436\u0435\u043B\u0435\u0441" }},
    { "label": { "type": "literal", "xml:lang": "vi", "value": "Los Angeles" }},
    { "label": { "type": "literal", "xml:lang": "zh", "value": "\u6D1B\u6749\u77F6" }},
    { "label": { "type": "literal", "xml:lang": "ca", "value": "Los Angeles" }},
    { "label": { "type": "literal", "xml:lang": "cs", "value": "Los Angeles" }},
    { "label": { "type": "literal", "xml:lang": "de", "value": "Los Angeles" }},
    { "label": { "type": "literal", "xml:lang": "en", "value": "Los Angeles" }} ] } }
