Practical Ontology Development Observation Ontology is at the heart of current semantic (web) solutions Experience shows it is quite practical to create and maintain targeted (application/domain) ontologies: Few classes to many tens (few hundreds) of classes and relationships (types); very small number of designers/knowledge experts; descriptional component (schema) designed with GUI Hundreds of thousands to several millions entities and relationships (instances/assertions) Tens of knowledge sources; automatically populated by knowledge extractors Primary scientific challenges faced: named entity identification, entity ambiguity resolution and data cleanup Total effort: few person weeks
Ontology-driven Information Systems have becoming reality Software and practical tools to support key capabilities and requirements for such a system are now available: Ontology creation and maintenance Automatic Classification Ontology-driven Automatic Semantic Metadata Extraction/Annotation and Semantic normalization Utilizing semantic metadata and ontology Blended Semantic querying/browsing/analysis Information and application integration Analysis and discovery for business/market/national intelligence Achieved in the context of successful technology transfer from academic research (LSDIS lab, UGA’s SCORE technology) into commercial product (Semagix’s Freedom)
