The 1-Sentence Summary is an experiment in automatically extracting the most significant sentence from a web page such as a blog post, an article or a paper. The purpose for using the 1-Sentence Summary is to allow the reader to instantly focus on the key idea and keywords of the text.
The thought here is that summaries offer a practical and instant shortcut to finding out if information is valuable or of no use.
Summaries provide the readers with the minimum essential information needed to grasp the essence of the text. Together with keywords they provide clear focus to the readers sparing them from information overload.
