The Semantic Web Company’s Andreas Blumauer demonstrates how Thesaurus-based Text Mining with PoolParty Extractor provides high-precision text analytics. Content can be transformed into SKOS/RDF and later used for semantic mashups. Entity extraction based on knowledge graphs, in contrast to simple term extraction, offers an approach for information integration based on semantic knowledge models.
PoolParty Thesaurus Server integrates with Virtuoso Universal Server (see: http://virtuoso.openlinksw.com), allowing thesaurus managers to’deploy’ stable versions of their knowledge graphs into a Virtuoso RDF store. Virtuoso is well-known for its high performance even when complex queries are made across different (named) graphs.
The Semantic Web Company’s Andreas Blumauer presents a short demo of this feature which opens up completely new options for enterprise data integration.
At its core, PoolParty is built upon SKOS, the W3C’s standard for defining controlled vocabularies like taxonomies or thesauri. As of release 3.2.2, however, PoolParty offers a highly flexible RDF schema editor to introduce either widely accepted schemas like FOAF and SIOC or customized schemas created to meet the user’s needs. The Semantic Web Comapany’s Andreas Blumauer shows you how.
Sometimes it is useful to have a little help when adding details to the fields describing a term. The autopopulate feature in PoolParty can help find related terms, alternative labels and a host of other information. The Semantic Web Company’s Andreas Blumauer shows you how.
Thesauri are designed to cover a particular domain or area of knowledge. However, sometimes it is useful to a link concept in one domain with a concept in another. Taxonomist Gaby Nicas shows how PoolParty makes it simple to link concepts between projects.
As a thesaurus evolves it is important to keep track of changes or provide information to help clarify decisions made about a term. Taxonomist Gaby Nicas shows how PoolParty makes it simple to add explanatory notes to a concept and track changes.
The Semantic Web Company’s Andreas Blumauer explains how to create and manage SPARQL lists (‘pick lists’) and collections in PoolParty. Collections are part of the SKOS standard, which is the basis for PoolParty. With lists and collections several elements like drop-down menus or menu structures can be generated for third-party applications.
Documents can be added to a PoolParty document library in a variety of ways, including via URL, uploading Word or PDF files, copying and pasting, or even uploading a zip file; assigning metatags to the documents makes them easy to find later. Taxonomist Gaby Nicas demonstrates just how easy it is to add information to PoolParty and create new or add existing tags from the project thesaurus.
The Semantic Web Company’s Andreas Blumauer presents a quick overview of the features and functions of PoolParty’s main menu tabs, showing how you can manage taxonomies and other controlled vocabularies.
In the evolution of a thesaurus sometimes it makes sense to take two separate categories or concepts and make them one. Whether it is a single concept or a top-level concept with terms under it, Taxonomist Gaby Nicas shows how this is quickly and easily done in PoolParty.
