MediaWiki查询和/或WikidataQuery来查找维基百科文章 [英] MediaWiki Query and/or WikidataQuery to find Wikipedia article
问题描述
与AngularJS相比，这不是一个关于维基媒体和维基数据查询API的问题。
虽然我想在做一个不是问题的特定查询后，在AngularJS中显示维基百科文章的内容。我已经知道如何显示它......问题在于搜索文章或文章。
我试图通过历史事件日期查询维基百科以及地理位置。
让我们挑选一个随机事件，任何事件。比如说1986年莫桑比克图波列夫图-134撞车。链接： http://en.wikipedia.org/wiki/1986_Mozambican_Tupolev_Tu-134_crash p>
从文章中，我可以看到确切日期： 1986年10月19日
以及地理位置事件： -25.911389,31.957222
我试图在AngularJS中构建一个可以使用日期范围和/或地理位置坐标来查找事件。
我知道mediawiki现在有一个地理定位API，我可以通过关键字或坐标查找上述事件。结果还发现了任何其他的文章，使用这种方式存在于其周围的特定半径范围内：
但是，无法通过时间点或事件日期使用mediawiki进行搜索。
另一方面，Wikidata有两种搜索数据的方法...它具有日期范围以及地理位置。
但是，当查询运行时，我不知道返回的是什么。
例如，当我使用这个查询字符串时：
https ：//wdq.wmflabs.org/api？q = AROUND [625，-25.911389,31.957222,5]％20AND％20BETWEEN [585,1985,1987]
$ b它返回这个：
{status：{error： OK，items：1，querytime：544ms，parsed_query：（AROUND [625，-25.9114,31.9572,5]
AND
BETWEEN [585，+ 00000001985 -00-00T00：00：00Z，+ 00000001987-00-00T00：00：00Z]）}，items：[950273]}
使用wikidata的查询工具：
我可以看到 950273 代表文章以某种方式。我只是不确定如何使用它来将我引导到wikipedia中的实际文章。
我不知道 items是什么：[950273 ] 表示，或者如何使用它来使我能够访问维基百科文章并在AngularJS中显示该文章的内容。
有没有办法按历史事件的日期以及地理位置查询，可以使用mediawiki或wikidata或两者的组合？ $ b
编辑：
这是我上面问题的解决方案，它看起来有点像黑客......但它起作用了，现在已经足够了。控制器。
$ b $.controller（'WikiQueryCtrl'，['$ scope'，'$ http'，function（$ scope，$ http）{
$ http（{
//这些地理坐标和日期范围最终将是动态的。
url：'https://wdq.wmflabs.org/api?q= AROUND [625，-25.911389,31.957222,5]％20于是％20BETWEEN [585,1985,1987]&安培; CAL lback = JSON_CALLBACK'，
method：'jsonp'
}）
.success（function（response）{
var items = response.items;
$ scope.jason = items;
var wikiDataString ='http://www.wikidata.org/w/api.php?action=wbgetentities&format=json&ids=Q'+ items +'&; props = sitelinks％7Csitelinks％2Furls&回调= JSON_CALLBACK';
$ http（{
url：wikiDataString，
method：'jsonp'
}）
.success（function（response2）{
$ scope。 jason2 = response2;
var url = response2.entities [Q+ items] .sitelinks.enwiki.url;
var wikipediaTitle = url.substr（24，url.length）;
var wikipediaURL ='http://en.wikipedia.org/w/api.php?action=query&prop=extracts|info&exintro&titles='+ wikipediaTitle +'& format = json& explaintext& redirects& inprop = url& indexpageids& format = json& callback = JSON_CALLBACK';
$ http（{
url：wikipediaURL，
method：'jsonp'
}）。成功（函数（response4）{
var query = response4.query;
var pageID = respons e4.query.pageids;
var title = response4.query.pages [pageID] .title;
var fullurl = response4.query.pages [pageID] .fullurl;
var content = response4.query.pages [pageID] .extract;
$ scope.title = title;
$ scope.content = content;
$ scope.fullurl = fullurl;
$ scope.jason = query;
}）;
}）;
}）;
}]）;
解决方案950273 是维基数据实体ID。您可以在 https://www.wikidata.org/wiki/Q950273 找到实体本身。
通过使用它，您可以使用API和动作
wbgetentities查询连接到它的文章的维基数据并请求sitelinks和附加链接/ url像这样： http://wikidata.org/w/api.php?action=wbgetentities&format=json& ids = Q950273& props = sitelinks％7Csitelinks％2Furls
或者尝试直接使用特选语言版本：GoToLinkedPage。例如。 https://www.wikidata.org/wiki/Special:GoToLinkedPage/enwiki/Q950273
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.
Let's pick a random event, any event. Let's say "1986 Mozambican Tupolev Tu-134 crash". Link: http://en.wikipedia.org/wiki/1986_Mozambican_Tupolev_Tu-134_crash
From the article, I can see the exact date: 19 October 1986
as well as the geo-location of the event: -25.911389, 31.957222I'm trying to build a search in AngularJS that can use either a date-range and/or geolocation coordinates to find an event.
I am aware that mediawiki has a geolocation API now, and I am able to find the above event by either keyword or coordinates. The result also turns up any other articles that exist within a certain radius around it using this:
However, there is no way to do a search with mediawiki by a point in time or the date of the event.
Wikidata on the other hand has two methods of searching data... it has a date range as well as geolocation.
However, when a query is run, I have no idea what is being returned.
For example, when I use this query string:
https://wdq.wmflabs.org/api?q=AROUND[625,-25.911389,31.957222,5]%20AND%20BETWEEN[585,1985,1987]it returns this:
{"status":{"error":"OK","items":1,"querytime":"544ms","parsed_query":"(AROUND[625,-25.9114,31.9572,5] AND BETWEEN[585,+00000001985-00-00T00:00:00Z,+00000001987-00-00T00:00:00Z])"},"items":[950273]}
Using wikidata's query tool:
I can see that 950273 represents the article in some way. I'm just not sure how to use that to direct me to the actual article in wikipedia.
I don't know what "items": [950273]" represents, or how to use it to get me to the wikipedia article and display the contents of that article in AngularJS.
Is there a way to do both a query by date of the historical event as well as by geolocation. Either by using mediawiki or wikidata or a combination of the two?
EDIT: This is the solution to my question above. It seems like a bit of a hack... but it works. Good enough for now. Here is my controller.
.controller('WikiQueryCtrl', ['$scope', '$http', function($scope, $http) { $http({ //these geo coordinates and the date ranges will eventually be dynamic. url: 'https://wdq.wmflabs.org/api?q=AROUND[625,-25.911389,31.957222,5]%20AND%20BETWEEN[585,1985,1987]&callback=JSON_CALLBACK', method: 'jsonp' }) .success(function(response) { var items = response.items; $scope.jason = items; var wikiDataString = 'http://www.wikidata.org/w/api.php?action=wbgetentities&format=json&ids=Q' + items + '&props=sitelinks%7Csitelinks%2Furls&callback=JSON_CALLBACK'; $http({ url: wikiDataString, method: 'jsonp' }) .success(function(response2) { $scope.jason2 = response2; var url = response2.entities["Q" + items].sitelinks.enwiki.url; var wikipediaTitle = url.substr(24, url.length); var wikipediaURL = 'http://en.wikipedia.org/w/api.php?action=query&prop=extracts|info&exintro&titles=' + wikipediaTitle + '&format=json&explaintext&redirects&inprop=url&indexpageids&format=json&callback=JSON_CALLBACK'; $http({ url: wikipediaURL, method: 'jsonp' }).success(function(response4) { var query = response4.query; var pageID = response4.query.pageids; var title = response4.query.pages[pageID].title; var fullurl = response4.query.pages[pageID].fullurl; var content = response4.query.pages[pageID].extract; $scope.title = title; $scope.content = content; $scope.fullurl = fullurl; $scope.jason = query; }); }); }); }]);
解决方案950273 is the Wikidata entity ID. You find the entity itself at https://www.wikidata.org/wiki/Q950273
By using that you can query Wikidata for the articles connected to it using the API and the action
wbgetentitiesand ask forsitelinksandsitelinks/urllike this: http://wikidata.org/w/api.php?action=wbgetentities&format=json&ids=Q950273&props=sitelinks%7Csitelinks%2FurlsOr try going to the language version of your choice directly using Special:GoToLinkedPage. Eg. https://www.wikidata.org/wiki/Special:GoToLinkedPage/enwiki/Q950273
