Our ranking algorithm uses timestamp as one of the features. We use a 99.5 percentile of all documents timestamps as a current timestamp.
However, if there are many documents from "future" (as in the English part of the test dataset), they will be boosted to the top.
It can be easily fixed with changing the percentile border. It is not the issue with clustering.
In the screenshot one can see some of the "future" documents. The true current timestamp is the 29th of November.

And the Entertainment category in the "top" task was named "entArtainment" by mistake :/
In "categories" it has correct name and shows nicely.

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

– Большое количество чрезмерно широких сюжетов, а также сюжетов, состоящих из одной статьи.

– Заголовки части сюжетов слишком размытые (информация не подаётся в краткой нейтральной форме). 

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

We had to fix the following issues before running the algorithm and will apply relevant penalties during the final scoring:
- "Illegal instruction" error, build manually

We also have another problem with Entertainment category, it occurs because of misspell in code. It is named "entertainment" in src/rank/rank.cpp
No entertainment.

Thank you for your feedback! As I stated in the comments and in the first issue, the reason for an empty Entertainment category is a misspelling in the name of the category in code.
