OWL ontologies are nowadays a quite popular way to describe structured knowledge in terms of classes, relations among classes and class instances. In this paper, given an ontology target T, we address the problem learning fuzzy concept inclusion axioms that sufficient conditions for being individual instance T (and which degree). To do so, present Fuzzy OWL-Boost relies on Real AdaBoost boostin...

This paper describes a new syntax that can be used to write OWL 2 ontologies. The syntax, which is known as TEX-OWL, was developed to address the need for an easy-to-read and easy-to-write plain text syntax. TEX-OWL is inspired by LTEX syntax, and covers all construct of OWL 2. We designed TEXOWL to be less verbose than the other OWL syntaxes, and easy-to-use especially for quickly developing s...

Both ISO's Topic Map Standards and the W3C's Semantic Web Recommendations provide the means to construct meta-level semantic maps describing relationships between information resources. Developed independently, attempts at interoperability between the original Topic Map standard and RDF have proved challenging. However, ISO 13250's drafting of an explicit Topic Map Data Model (TMDM) early in 20...
