Other platforms, review domains and languages While we focused on Amazon product reviews written in English, the majority of the features discussed in Section 3 are platform-, domainand language-independent, and the existence and importance of moderating factors described in Section 4 is by no means limited to product reviews.
we encourage researchers to evaluate the usefulness of these features and study these moderating factors in different domains, platforms, and languages, possibly identifying new features and moderating factors.
