问题 I'm trying to extract interlanguage related articles in Wikidata dump. After searching on the internet, I found out there is a tool named Wikidata Toolkit that helps to work with these type of data. But there is no information about how to find related articles in different languages. For example, the article: "Dresden" in the English language is related to the article: "Dresda" in the Italiano one. I mean the second one is the translated version of the first one. I tried to use the toolkit,

问题 How to get Wikipedia page (in a particular language, say French) from the Wikidata Id (ex: Q19675)? The question seems obvious but strangely, I find nothing on the web.

问题 Wikidata has an item called smartphone model. I want to get all instances of it. QUESTION: How to get the identifiers of the instances programmatically, using the live server?

问题 I'm trying out the wikidata API but have some trouble with the search query "Jas 39 C Gripen". It returns results on the wikidata website, but not if I use the API.

问题 This isn't so much a question abut AngularJS as it is about the Wikimedia and Wikidata query API's. Although I am trying to display the content of a Wikipedia article in AngularJS after doing a certain query that isn't the problem. I already know how to display it... the problem is the search for an article or articles. I'm trying to query Wikipedia by historical event date as well as by geo-location.

问题 I've made an android app that uses the JSON Google image search API to provide images but I have noticed that Google have stopped supporting it. I have also discovered that Wikidata sometimes provides a image property on some items, however I can't seem to get the URL location of the image using the Wikidata API.
