Should I use a dictionary, a taxonomy or an ontology?

In order to understand which element best suits your project it is import to understand what they are and what they can do.


In a Lettria project, list of words having a common point and intended to be identified in data.

Example use case: A dictionary of rude words and a dictionary of medical words can be used to avoid coarseness and protect privacy on networks.


A taxonomy is a hierarchical classification of things or ideas. Unlike ontologies, taxonomies do not contain properties (relationships and attributes).

Example use case: The classification of music could have separate facets organized by genre, year created and record label.


Knowledge representation system, usually more complex than a taxonomy, used to organize classes of things or concepts in a hierarchical way and to assign them properties.

Example use case: Ontologies can be used to extract information to fill out databases and CRMs.
