Text Analysis Methods

Word Embedding
Uses word vectors as points in the path
Sentence Embedding
Uses sentence vectors as points in the path
Sentence Grammar Space
Uses sentence statistics (i.e. number of adjectives / number of words) as points in the path
Document Grammar Statistics
Takes document statistics as values for each epicycle.

Pattern

Connect by Distance
Connects the dots in the order based on the next closest point.
Connect by Word Order
Connects the dots in the order the words appear in the text.
Flower by Distance
Path goes back to the center after each point moving to the next closest point.
Flower by Word Order
Path goes back to the center after each point moving to the next word in the text.
