Basic Concept

Definition

Summarization is the task of producing a shorter version of one or several documents that preserves most of the input's meaning.

Types of summarization

Extractive summaries (extracts) are produced by concatenating several sentences taken exactly as they appear in the materials being summarized.

Abstractive summaries (abstracts), are written to convey the main information in the input and may reuse phrases or clauses from it, but the summaries are overall expressed in the words of the summary author.

Summary Informativeness evaluation

  • ROUGE-N: measures the N-gram units common between a particular summary and a col- lection of reference summaries where N determines the N-gram’s length. E.g., ROUGE-1 for unigrams and ROUGE-2 for bi-grams.
  • ROUGE-L: computes Longest Common Subsequence (LCS) metric.
  • BLUE : BLEU is basically calculated on the n-gram co-occerance between the generated summary and the gold (You don't need to specify the "n" unlike ROUGE).
  • METEOR : based on the harmonic mean of unigram precision and recall, with recall weighted higher than precision.

DataSet

  • Annotated English Gigaword

    • for sentence summarization
  • CNN/Daily Mail dataset

    • for document summatization
  • DUC 2004

  • CORNELL NEWSROOM

    • is a large dataset for training and evaluating summarization systems. It contains 1.3 million articles and summaries written by authors and editors in the newsrooms of 38 major publications. The summaries are obtained from search and social metadata between 1998 and 2017 and use a variety of summarization strategies combining extraction and abstraction.
  • Google Dataset

    • Large corpus of uncompressed and compressed sentences from news articles.
