What is a Semantic CMS? Traditional CMS Semantic CMSAtomic unit: Document Atomic unit: EntityProperties as meta-data Semantic meta-data e.g. author Defined entity types tags, keywords Linked entitiesKeyword search for Semantic search for strings in docs entities and their relationsDocument Management Knowledge Management Document types Entity management Document workflow Ontologies What Apache Stanbol Can Do for You! by @fctwitt 5

Do Not Replace – but Extend• No need to replace existing CMS technology• Stanbol components offer service oriented integration• Integration through a RESTful web service API Traditional CMS HTTP Stanbol Semantic Services Database What Apache Stanbol Can Do for You! by @fctwitt 6

Integration scenarios• Standalone REST API via included HTTP server Web Apps• Web Application REST API via Servlet-Container• Embedded Java Application OSGi Environment as part of another Java application App What Apache Stanbol Can Do for You! by @fctwitt 7

Help included• Each component offers its documentation at an HTML endpoint as part of its RESTful interface http://localhost:8080 What Apache Stanbol Can Do for You! by @fctwitt 8

Knowledge Management & Reasoning• Manage ontology networks Ontology Manager• Transform ontologies Rules• Inference knowledge Reasoners What Apache Stanbol Can Do for You! by @fctwitt 17

Ontology Manager• Controlled environment for managing ontologies• Manage ontology networks to activate/deactivate parts of complex ontologies• Manage user sessions for ontologies allowing local user changes What Apache Stanbol Can Do for You! by @fctwitt 18

Rules• Construction and execution of inference rules• Inference rules, also called transformation rules, take premises and return conclusions• Rules can be organized in recipes which allow to execute a set of rules as a whole• Example • Define rules for doing integrity checks on data fetched from heterogeneous external data sources What Apache Stanbol Can Do for You! by @fctwitt 19

Reasoners• Common API for existing reasoning services• Supports different reasoners and configuration in parallel• Supported third-party reasoners • Jena RDFS • OWL • OWLMini • HermiT What Apache Stanbol Can Do for You! by @fctwitt 20
