问题描述
好，所以我试图从Wikidata中获取有关电影的信息，以这部电影为例: https: //www.wikidata.org/wiki/Q24871
Ok so I'm trying to get information from Wikidata about movies, take this movie for example: https://www.wikidata.org/wiki/Q24871
在页面上，数据清楚地以可读格式显示，但是当您尝试通过API提取数据时，会得到以下信息: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q24871
On the page the data is clearly displayed in a readable format, however when you trying to extract it via the API you get this: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q24871
这是其中的一部分:
"P272": [
{
"id": "q24871$4721C959-0FCF-49D4-9265-E4FAC217CB6E",

问题是我不确定如何将类似部分转换为可读文本.我知道API使用唯一的ID来调用类及其属性之间的链接，但我仍然被卡住.
The problem is I'm not sure how to convert sections like that into readable text. I get the API is calling a link between a class and its properties using unique IDs but I'm still stuck.
这实际上是否可能，或者我在吠错树了吗?
Is this actually possible at present or am I barking up the wrong tree?
推荐答案
您需要查找的是每个语句中的numeric-id，并添加前导Q以恢复您的wikidata id，这将导致['Q775450', 'Q3041294', 'Q646968', 'Q434841', 'Q11920']
What you should be looking for are the numeric-ids in each statements and add a leading Q to recover your wikidata ids, which should result to ['Q775450', 'Q3041294', 'Q646968', 'Q434841', 'Q11920']
[更新:您现在可以直接在mainsnak.datavalue.value.id上访问Q id，而不必从numeric-id]构建它.
[update: you can now directly access the Q id at mainsnak.datavalue.value.id, instead of having to build it from the numeric-id]
可以使用 wikidata-sdk (我开发的JS库)完成 simplifyClaims函数
This can be done using wikidata-sdk (a JS lib I developed) simplifyClaims function
获得这些ID后，您只需要使用wbgetentities API请求实体标签: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q775450|Q3041294|Q646968|Q434841|Q11920&format=json&props=labels
Once you got those ids, you just need to request entities labels using the wbgetentities API:https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q775450|Q3041294|Q646968|Q434841|Q11920&format=json&props=labels
您甚至可以使用languages参数获得某些语言的结果: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q775450|Q3041294|Q646968|Q434841|Q11920&format=json&props=labels&languages=en|de|fr
you can even get results for only some languages, using the languages parameter: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q775450|Q3041294|Q646968|Q434841|Q11920&format=json&props=labels&languages=en|de|fr
