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

– Отсутствуют некоторые главные сюжеты в разделе ‘Main’ и внутри категорий. Заголовки части сюжетов слишком размытые (информация не подаётся в краткой нейтральной форме).

– Нарушена сортировка некоторых 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:
- invalid top category name, fixed "all" => "any"
Not pure articles similarity, except this - one of my favorites
Low precision for 'Other' in news detection, too many actual news weren't detected as news.

Right, it can be improved for English. Although these articles are borderline news:
Black Friday rush:
There is no actual event, just a photo of shoppers lining up with some comments.

The article is written almost as advertisement, which my filtering doesn't like.

If you scroll the "Other" part in News further, you will see that there are in fact very few articles that could be called genuine news.
