Generating Wikipedia by Summarizing Long Sequences
Abstract
We show that generating English Wikipedia articles can be approached as a multi-
document summarization of source documents. We use extractive summarization
to coarsely identify salient information and a neural abstractive model to generate
the article. For the abstractive model, we introduce a decoder-only architecture
that can scalably attend to very long sequences, much longer than typical encoder-
decoder architectures used in sequence transduction. We show that this model can
generate fluent, coherent multi-sentence paragraphs and even whole Wikipedia
articles. When given reference documents, we show it can extract relevant factual
information as reflected in perplexity, ROUGE scores and human evaluations.
