Discussion on Uncertainty Ontology for Annotation
and Reasoning (a position paper)

• J. Dedek, A. Eckhardt, L. Galambo, P. Vojtá
• Charles University Prague

2
Positions for discussion

• Discuss the what, who, when, where, why and how
• of uncertain reasoning
• First annotate (WIE) then reason
• Uncertainty Ontology and/or ontology for
  uncertainty
• annotation (and reasoning)
• Scope whole web?
• Uncertainty coming from a third party annotation
• Stepwise semantization of the web

Context of Our Experiments Semantic Web
Semantic Data Extraction

• Domain of traffic accidents
• Semantics given by human
• Generalized extracted by ILP

• Get semantics form Web of today
• Czech pages, Czech texts
• Czech linguistic tools

Proposal of ontology for uncertainnty annotation
First extract (WIE) then annotate
and finally reason (query)

Idea of web semantization
