Contributors metainfo: reputation and more

Oleg Komarov on 8 Feb 2011

Latest activity Reply by Rena Berman on 7 Jun 2023

As asked by Vieniava in "How to make a list of user's reputation?", some of us came up with interesting ideas on how to fill an updated list with the reputation scores of the contributors to Answers.

I took the initiative to compile a public list of users with meta info:

position (desc ordering by reputation)
id
nickname (truncated to fit the page)
reputation
# of comments
# of questions asked
% accept rate
# of posts answered
# of accepted answers

The code used to compile the list is available at the bottom.

EDIT

TMW team implemented a page with the metascores: http://www.mathworks.com/matlabcentral/answers/contributors

Please refer to it and congrats to the team!

Use this function to retrieve info from the link above:

function [metainfo, elapsedTime] = metainfo(type,order)
% METAINFO - Retrieve metainfo on contributors to www.matworks.com/.../answers
%
%   METAINFO Retrieve data sorted by reputation in descending order 
%
%   METAINFO(TYPE,ORDER) Specify TYPE and sorting ORDER as
%       type :  'reputation'
%               'questions'
%               'answered'
%               'accepted'
%
%       order:  'asc'
%               'desc'
%   
% Examples:
%
%     % Standard call (rep, disc)
%     info = metainfo;
%       
%     % Sort by question answered in descending order
%     info = metainfo('an','d');

I think it would be a great idea to identify prolific users in each toolbox. For example, I do not have enough leisure time, and of course expertise, to reach to the top of the leaderboard. But I regularly check the questions asked about SimEvents and answer the majority of the questions asked there.
