The Rosoka Extraction Engine (REE) is the heart of the Rosoka product suite. The REE is an API-driven, data-independent data extraction engine. It is a component tool designed to be integrated into a larger system via its Java API. The REE uses a rule set that is particular to the language and data domain of the documents it will process.

The Rosoka Salience Engine (REE) is an API-driven software engine that provides the relative importance of a given entity to its own document and to a collection of documents via an ordered, weighted list. The RSE uses information from an entity extraction engine, such as the REE, to perform its proprietary calculations.

The Rosoka Document Viewer (RDV) is a graphically-based tool to view the results from the different Rosoka products. Depending on the type of license purchased, the RDV can also initiate the other Rosoka products to process documents. The RDV provides document entity highlight, entity heat-map, and node/link views.
