Lexical level, transforming a string of characters into a sequence of atomic entities, called tokens.
Syntactic level, identifying and tagging (anotating) each token’s functions.
Semantic level, extracting of meaning and relationships between pieces of knowledge derived from the structures identified in the syntactical level.
Levels of text representation

Tag Cloud
A tag cloud (word cloud, or weighted list in visual design) is a visual representation for text data, typically used to depict keyword metadata (tags) on websites, or to visualize free form text.
'Tags' are usually single words, normally listed alphabetically, and the importance of each tag is shown with font size or color.

The contexts are arranged in a tree-like branching structure to reveal recurrent themes and phrases.
