Unfortunately we tested our submission only on data where both English and Russian articles are present. Only one language in the input leads it to NullPointerException.

It could be fixed with just one line:
List<String> myLangFiles = langs.getOrDefault(testLang, new ArrayList<>());
instead of
List<String> myLangFiles = langs.get(testLang);

Is it possible to retest the submission? (New binary could be downloaded here: https://drive.google.com/file/d/1xeKVhzb0S9mCVFfYKLtIFVzyc9GrebXp/view?usp=sharing)

As I said in previous comment, we expected dataset to contain both English and Russian articles.

It is possible to fix our solution without changing source code.

There are two possible ways:
1. Add two dummy articles (English and Russian) to all datasets. Here is examples of such files: https://drive.google.com/drive/folders/1qMVHCnG5DR72U_hCbMjDm57ngLkoj4at?usp=sharing
2. Combine en_source_dir and ru_source_dir into one directory and run a submission on it instead of separate executions.

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

– Сюжеты отсортированы по количеству статей в них.

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

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

Количество статей в сюжете действительно является одним из важных критериев сортировки, но далеко не единственным.

Это хорошо заметно на сюжетах по 20-50 статей.

We had to re-run your algorithm with extra articles and will apply relevant penalties during the final scoring.
