Testing and Issues

You can test this app and submit issues during the testing period of the Data Clustering Contest contest.

Entries with serious issues will not be able to win the contest, but even minor issues might be important for overall results.




At it says that "We will not evaluate apps that require more than 60 seconds for each batch of 1000 files passed in source_dir.".

From this statement (due to the “batch of 1000” substring) I inferred that processing will be done in batches of 1K and hard-wired a “break” at 1K, hence the submitted binary will not process anything beyond this file count.
I removed the break and it processes “raw” directory (35075 files) which you provided with the following timings (on archaic MacBook Pro 2012):

top: 241 sec
threads: 235 sec
categories: 139 sec
news: 125 sec
languages: 130 sec
JSON responses for each request are here:

I can send you the binary without this 1K limit per directory if you want to rerun it on your end. Or you can drop the break (lines 89 and 92) and recompile (it’s straightforward and should take 5-10 minutes max).

В ходе предварительного тестирования алгоритма были выявлены следующие недостатки в ранжировании:

– Отсутствуют некоторые главные сюжеты в разделе ‘Main’ и внутри категорий. Сюжеты отсортированы по количеству статей внутри.

– Заголовки части сюжетов слишком размытые (информация не подаётся в краткой нейтральной форме). Отсутствуют знаки препинания во многих названиях сюжетов: например, пропущены запятые и дефисы.

– Нарушена сортировка статей в сюжетах: релевантные статьи смешаны с нерелевантными.

This entry had to be reuploaded after the deadline due to an issue and will not receive any prizes in the current stage.

It's author, however, may get the chance to participate in the next round of the Data Clustering Competition.
