Semantic tree or Tree of knowledge is one of the implementations of the Web 3.0 W3C SKOS standard (Simple Knowledge Organization Systems).

Our trees of knowledge are based on the methodology of the semantic mapping used in the semiotics and linguistic semantics, naming of the nodes (semantic entities) is using onomasiology approaches.

Main features:

• Nodes of the tree are concepts (semantic entities - definitions, rights, obligations, ...).
• These concepts are usually taken from document, web site or some dataset in the process of the semantic decomposition.
• All important semantic entities in the document are identified, named and put to the tree.
• Structure of the tree reflects formal structure of the document or web site.
• For example: in the EU legal document you have Parts, Titles, Recitals, Articles, Paragraphs, Sub-paragraphs - and semantic entities are hidden across all of them (definitions, rights, obligations, fines, authorities, responsibilities, procedures, ...).
