The Semantic Puzzle

Why SKOS should be a focal point of your linked data strategy


The Simple Knowledge Organization System (SKOSSimple Knowledge Organization System (SKOS) is a family of formal languages designed for representation of thesauri, classification schemes, taxonomies, subject-heading systems, or any other type of structured controlled vocabulary. SKOS is built upon RDF and RDFS, and its main objective is to ...) has become one of the ‘sweet spots’ in the linked data ecosystem in recent years. Especially when semantic web technologies are being adapted for the requirements of enterprises or public administration, SKOS has played a most central role to create knowledge graphs.

In this webinar, key people from the Semantic Web CompanyThe Semantic Web Company (SWC), based in Vienna, provides companies, institutions and organizations with professional services related to the Semantic Web, semantic technologies and Social Software will describe why controlled vocabularies based on SKOS play a central role in a linked data strategy, and how SKOS can be enriched by ontologies and linked data to further improve semantic information managementInformation management (IM) is the collection and management of information from one or more sources and the distribution of that information to one or more audiences. This sometimes involves those who have a stake in, or a right to that information. Management means the organization of and ....

SKOS unfolds its potential at the intersection of three disciplines and their methods:

  • library sciences: taxonomyTaxonomy is the practice and science of classification. The word finds its roots in the Greek τάξις, taxis (meaning 'order' or 'arrangement') and νόμος, nomos (meaning 'law' or 'science'). Taxonomy uses taxonomic units, known as taxa. In addition, the word is also used as a count noun: ... and thesaurus management
  • information sciences: knowledge engineering and ontology, an ontology is a formal representation of knowledge as a set of concepts within a domain, and the relationships between those concepts. It is used to reason about the entities within that domain, and may be used to describe the domain. In theory, an ontology is a "formal, explicit ... management
  • computational linguisticsComputational linguistics is an interdisciplinary field concerned with the statistical or rule-based modeling of natural language from a computational perspective.Traditionally, computational linguistics was usually performed by computer scientists who had specialized in the application of ...: text miningText mining, sometimes alternately referred to as text data mining, roughly equivalent to text analytics, refers to the process of deriving high-quality information from text. High-quality information is typically derived through the divining of patterns and trends through means such as ... and entity extraction

Linked Data based IT-architectures cover all three aspects and provide means for agile data, information, and knowledge management.

In this webinar, you will learn about the following questions and topics:

  • How SKOS builds the foundation of enterprise knowledge graphs to be enriched by additional vocabularies and ontologies?
  • How can knowledge graphs be used build the backbone of metadata services in organisations?
  • How text mining can be used to create high-quality taxonomies and thesauri?
  • How can knowledge graphs be used for enterprise information integration?

Based on PoolParty Semantic Suite, you will see several live demos of end-user applications based on linked data and of PoolPartyWeb based ontology manager which can serve as a central hub for your knowledge organization. With PoolParty you can organize and maintain knowledge models based on widely accepted specifications like RDF, SPARQL and SKOS.’s latest release which provides outstanding facilities for professional linked data management, including taxonomy, thesaurusA thesaurus is a book that lists words grouped together according to similarity of meaning, in contrast to a dictionary, which contains definitions and pronunciations. The largest thesaurus in the world is the Historical Thesaurus of the Oxford English Dictionary, which contains more than ... and ontology management.
