PoolParty Thesaurus Server

Taxonomies and thesauri in the age of the web most often should be engineered and maintained in a collaborative manner. PoolParty is fully web-based; administrators need only a web browser to do all typical CRUD operations like creating, deleting or editing concepts or relations in a knowledge graph. Workflows and approval processes can be activated if desired.

The PoolParty graph modeling approach intertwines taxonomy and ontology management in a new way. SKOS taxonomies can be extended by ontologies like schema.org or FOAF. PoolParty users can create their own custom ontologies and schemas by reusing existing ontologies.


By means of text corpus analysis and automatic quality checks, PoolParty supports taxonomists to make sure that resulting thesauri comprise the content base in a meaningful way. Automatic suggestions for the supervised extension of taxonomies are generated through elaborated text mining algorithms.

The rise of Linked Data indicated by the enormous growth of the Linked Open Data cloud is an important argument for many organisations to maintain their own data at least partly based on Linked Data standards. PoolParty makes use of existing Linked Data sources, e.g. concepts can be aligned and enriched with additional information from sources like Dbpedia, Geonames, Wikidata or others. To generate seed-thesauri for a certain domain, DBpedia can be used a source to extract a taxonomy automatically.

A wiki frontend for each thesaurus project helps to involve other people than taxonomists in the thesaurus development process. Linking concepts is another flexible way to build thesauri in decentralised structures. Based on the linked data principles, thesauri can be maintained at different places but still can be connected to each other indicating that several concepts are similar or even identical to each other.

PoolParty is an enterprise-ready system, which offers high reliability, security, performance and mechanisms like failover, which guarantees smooth workflows and protection from loss of data. The use of open standards guarantee a high investment security. The integration of PoolParty thesauri with enterprise systems can be realised on top of standard APIs.

PoolParty Thesaurus Server is natively built on top of RDF triple stores. Its graph management facilities can be integrated with all graph stores providing a SAIL API (http://docs.rdf4j.org/sail/).
