Query: A Survey on Cross-Lingual Summarization   Cross-lingual summarization is the task of generating a summary in one
language (e.g., English) for the given document(s) in a different language
(e.g., Chinese). Under the globalization background, this task has attracted
increasing attention of the computational linguistics community. Nevertheless,
there still remains a lack of comprehensive review for this task. Therefore, we
present the first systematic critical review on the datasets, approaches and
challenges in this field. Specifically, we carefully organize existing datasets
and approaches according to different construction methods and solution
paradigms, respectively. For each type of datasets or approaches, we thoroughly
introduce and summarize previous efforts and further compare them with each
other to provide deeper analyses. In the end, we also discuss promising
directions and offer our thoughts to facilitate future research. This survey is
for both beginners and experts in cross-lingual summarization, and we hope it
will serve as a starting point as well as a source of new ideas for researchers
and engineers interested in this area.
