Locating the edit on the page
The text on the wiki web-page is divided into different sections each of them starting with a heading. The location of each edit is defined to be the heading of the section in which the edit lies. Hence we look for the first heading text above the edit in the text. The edits which do not lie under any heading are ignored.
Filtering
Teams which never completed their registration or withdrew their participation were filtered out. Number of teams which remained a part of the competition till the end was 1,122.
Out of these, we selected only those teams which edited the wiki for more than 5 days and had more than 50 edits in the wiki. This filtering was done in order to filter out teams which edit the wiki minimally and only in the end. After this filtering, we were left with 1,021 teams(91% of 1,122). We also made sure that the filtering did not change the fraction of teams winning a particular medal significantly(Fig)
Editors and Leaders
The members of the team which participated in editing the wiki are termed as editors. For analysis, we considered only the editors in the team. Hence, the size of the team is the number of editors and not the number of students on the team roster on the team information page. The leader was consequently defined as the editor who had the highest number of edits among all the editors of the team.
Complexity
The complexity of the wiki is defined as the number of sections in the whole wiki. The rationale behind this is that more number of sections implies more aspects in the project and higher amount of information generated by the team.
