My understanding so far has been that most of the research on text summarization has been done in English. However, I can’t find any reliable numbers for this. My best idea so far has been to search for “automatic summarization <language>” for a few languages on Google Scholar and see the number of results to get a rough estimate of the proportions. I get 42k for English, 25k for French, 24k for Spanish… But more surprising is I find 46k for Chinese. I would expect the results to be biased towards English, since my keywords are in English. Is it possible that more research has been done in summarization for Chinese than for English? Or am I overlooking something? Can you get more accurate numbers?
