Ontology and the Lexicon: A Roundtrip

Ontology design heavily depends on our assumptions that make sense of natural language requirements in formal terms. The emergence of the Web of Data is stressing this point even further. NLP techniques are more and more hybridized with knowledge engineering, but it is still unclear what happens when language technologies is used to enrich semantic data, or when we use formal semantics to manage lexical data. On the other hand, the past idealized views of a fully formal semantic web, or of NLP based on full-fledged formal semantics are hitting against scalability, usability, and practical engineering work. In this talk I propose a tolerant approach to add semantics to the web of data as well as to NLP and lexical data.
