Although the system explicitly combines biological events extracted from sentences to construct a long biological process, possibly leading to the propagation of errors, they reported fairly good performance and meaningful results, considering that it is the first attempt for document-level biological information extraction.
there are quite a few systems and corpora for document-level comprehension from a similar perspective in other domains, such as news articles (Hermann et al., 2015) and children's books (Hill et al., 2016).
