Pointer-generator summarization with a coverage penalty

Contribution grade

Neural summarization · Human-designed research method or resource

Reference score150,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Mixed vocabulary generation with attention-based source copying and added accumulated-attention coverage with an overlap penalty to reduce repetition in abstractive summaries.

Scientific scope

Mixed vocabulary generation with attention-based source copying and added accumulated-attention coverage with an overlap penalty to reduce repetition in abstractive summaries. Copying and coverage have earlier pointer/translation precedents; this record concerns their particular summarization integration. Copying may reproduce source errors and the penalty discourages, rather than guarantees elimination of, repetition or factual mistakes.
