Are there good baselines datasets or benchmarks for similarities/retrieval of long texts (extremely long documents, books, etc.)? Although significant both academically and applicational, I cannot get a hold of any significant dataset nor remarkable papers from the last AAA conferences.
Daily Mail, CNN or IMDB reviews are too short for me.
Pairwise Multi-Class Document Classification for Semantic Relations between Wikipedia Articles(2020) or Graph Convolutional Networks for Text Classification(2018)
For example, state to work on long text, but only use the first paragraph of the article.
My direction would probably be Wikipedia or Arvix datasets, but I would be happy to hear your experience or to find a relevant baseline to compete against.
