Summarization is creating a shortened version of text. Auto-summarization uses techniques to generate summaries of electronic documents. There are two categories of summarizers - linguistic summarizers use language knowledge like syntax and semantics to summarize, while statistical summarizers find important sentences using word frequencies and other statistical methods.
