THEMAS

The THEMAS system (Thesaurus Management System) is a Web based system for creating and managing multi- faceted multilingual thesauri with Greek or English language serving as the dominant language and a configurable number of reference translation languages. [Neo4j open source graph database] (http://neo4j.com/ "Neo4j") is used in the backend for data storage, [Neo4j-sisapi 1.4] (https://github.com/isl/Neo4j-sisapi/tree/1.4 "Neo4j-sisapi") for the interaction with the database and TELOS representation language structures are used as reference for the thesauri structure.

The possibilities offered by THEMAS in a thesaurus management level, cover a wide range of functions ranging from conservation and expansion of thesauri (functions of addition, modification and deletion of terms, hierarchies and facets, mass import / export of terms, creation of thesauri, saving and restoring backups etc.) to integration of multiple presentation methods (alphabetical, systematic graphical, hierarchical presentation) and access (alternative forms of navigation, support of complex search criteria, scalability search etc.).

The purpose of the system and the underlying modeling is to satisfy all the needs that derive during the administration of thesauri by accelerating and facilitating the procedures necessary for their conservation (maintenance) according to the consistency checks specified by the relevant ISO and ELOT standards.
