in-a-nutshell

in-a-nutshell creates a compressed summary of every text or article you give it.

How it works

The principle behind in-a-nutshell is very simple. It first determines the relevant words based on word frequency (excluding stop words) of a given text and then produces a summary out of the sentences that include said key phrases.

Due to it's simple nature in-a-nutshell can be imprecise at times, especially when it comes to contents of fictional nature. If you're looking for a more accurate solution, take a look at the TF-IDF algorithm.

Four super-heavy elements added to the periodic table on Wired

Output

Millions of science textbooks are now out of date as four new elements have been added to the periodic table.

The four super-heavy elements, discovered by scientists from Japan, Russia and America, complete the seventh row of the table as they become the first additions since 2011.

All of the new elements are man-made and were discovered by slamming lighter nuclei into each other and then tracking the decay of the radioactive elements.

Their addition to the periodic table marks a significant scientific breakthrough, though the elements do not exist for long before they breakdown and become different elements.

Relevant words: element, table...
