Themes
 

A theme is one or more significant word(s) from a text document that describe the unifying or dominant idea of that document. Often, this vocabulary contains the noun-phrases (i.e. a phrase that contains the noun) which convey the central ideas of the text. Furthermore, the frequently occurring noun-phrases yield concise themes. Semantic analytics – the knowledge about the meaning of words – is used to further define and refine the theme.

The benefit of theme extraction is that it helps Looksee identify the important words that are being used is in the text.
