In the night was thinking on idea which I think and hardly believe somewhere is already realized…because many people try to analyze the texts (I mean in science)…

So if we take some text and search on most used words…we got graph…the links between nodes are generated using the sentences. Trivial words are not used or can be used to identify the close relationships (for example he - > john) …

So if we have 4 sentences…

House has 4 windows. House has 2 doors. Doors are in white color. House is located in Riga.

We got graph… where links are between all concepts which are used in the sentence and the strongest links can be between concepts which are closer to each other. This is from nothing special stories… :)
