# 11.4: Literature and Reference Material

## Suggested readings for fuzzy and rough ontologies:

1. Thomas Lukasiewicz and Umberto Straccia. 2008. Managing Uncertainty and Vagueness in Description Logics for the Semantic Web. Journal of Web Semantics, 6:291-308. NOTE: only the section on fuzzy ontologies
2. Umberto Straccia and Giulio Visco. DLMedia: an Ontology Mediated Multimedia Information Retrieval System. In: Proceedings of the International Workshop on Uncertainty Reasoning for the Semantic Web (URSW-08), 2008. this is an example of an application that uses fuzzy DL
3. Keet, C.M. On the feasibility of Description Logic knowledge bases with rough concepts and vague instances. 23rd International Workshop on Description Logics (DL’10), 4-7 May 2010, Waterloo, Canada.

## Suggested readings for temporal ontologies:

1. Alessandro Artale, Christine Parent, and Stefano Spaccapietra. Evolving objects in temporal information systems. Annals of Mathematics and Artificial Intelligence (AMAI), 50:5-38, 2007. NOTE: only the $$\mathcal{DLR_{US}}$$ part, the rest is optional.
2. J. R. Hobbs and F. Pan. An ontology of time for the semantic web. ACM Transactions on Asian Language Processing (TALIP): Special issue on Temporal Information Processing, 3(1):6685, 2004.
