Let explore a Russian Wolfram Community, based on site vk.com:

For example, we want to find the most popular name in this community:

names={};
Do[
		url=URLBuild["api.vk.com/method/wall.get",{
				"count" -> 100,
				"owner_id"->"-1172233",
				"extended" -> 1,
				"offset" -> i
			}];
		data=(Developer`ReadJSONString@URLFetch[url])["response","profiles"][[All,2]];
		names=Join[names,data],
{i, 0, 4000, 100}];
WordCloud[names]

As you can see, the most popular name is Alexander. So if you are Alexander, you should join us =)

It is very interesting this example that you put, I believe that you can make use of Table and Append to make slightly more compact your code. But the idea that you’ve shared is very good.

Best regards

Is it possible to avoid facebook-like oddities on vk?

You can use your facebook account for registration.

By the way, If you wanna use an API - it’s open and registration is not necessary for using API.

I’ve no facebook account (because of the oddities of facebook), but the russian-language wolfram community is wolframmathematica - congratulations for still using the name Mathematica.

No way to upload a gif, jpeg, jpg, or png file

because it throws an invalid_attachment_storage it should possibly understand that the current system is not in the cyrillic font face.

Hello, Anna
I recently got introduced to extracting data from Url’s through API.
I love your example and I am very interested in understanding it thoroughly.
Would you mind explaining me your code?
I know it must be really basic to some in this community but I would appreciate it.
Thanks in advance.

Sorry for the delay.. But.. Why are you trying to register on russian wolfram community site? Unfortunately it’s in Russian… All I can do - give admin’s contacts =)

How Luis already mentioned, my code should be more compact. In fact, there are only 3 steps:

  1. URLBuild - crating URL for request to VK API
  2. URLFetch - getting response from VK API
  3. Putting all names from response together (unfortunately VK API allows to request only 100 records for one request, that’s why I need a cycle)

Than I just create a WordCloud.

If you need more information - please ask.

Because it should be possible.

Unfortunately it’s in Russian…

Sure, I read it.
