Challenge for Content Management

1.Annotation: Add meaning to the content
2.Link content: Bring content together in a meaningful way
3.Make content searchable: Add background knowledge to the content

in a nutshell
• W3C Semantic Web standards: Management of multi-lingual (corporate) thesauri & taxonomies on top of Semantic Web standards (SKOS, RDF, OWL & SPARQL)
• Usability: easy-to-use, web-based AJAX user interface
• Scalable Semantic Technologies: RDF Triple Store (SAIL), (Lucene) index engine and a phrase-extraction component
• Service oriented: PoolParty Server offers a Java-API & several interfaces: HTTP web services, SPARQL endpoint, Linked Data

Some Applications on top of PoolParty
• Tag recommendation: support users and content managers when annotating text
• Semantic Indexing: PoolParty TagEvent Store as a basis for a semantic index ( IndexBuilder)
• Similarity search: „Similarity“ is configurable: Certain features of a document can be „boosted“ (example: persons, places / user tags etc.)
• Semantic Search and Navigation: Thesaurus can be used for facetted and moderated search (examples: emteba.at, ecoi.net)
• Search Engine Dictionaries: provide company or domain specific terms for search engine dictionary

Consuming Linked Data
22
• advanced linked data look-up services
• expandable number of linked data sources already integrated
• linked data synchronisation mechanisms (beta)

Using SKOS context to link concepts to LD resources and semi-automatic population of thesaurus
Example: Thesaurus about arts and artists Concept „Painters“ with NT:
Kandinsky, Rembrandt and Berners-Lee
• Using broader and sibling concepts to help disambiguate and suggest the painter Berners-Lee
• Finding mutual categories from Dbpedia or Freebase
• Suggesting more NTs for Painters using LD categories

More background knowledge from thesauri and linked data can improve semantic search
• better disambiguation of search terms
• background knowledge of search terms help to „expand queries“
• better similarity search because of more metadata
• content augmentation through linked data
