Verioning Level IRI-level via owl:versionInfo
Verioning Method The version number (loosely) follows http://semver.org/ . All classes and properties starting with 0.x.y are not stable and might be removed anytime. As soon as a class or property reaches 1.x.y it will not be deleted anymore and will remain in the ontology. This means it will be terminological stable. The version number will be incremented to 2.x.y if use of the URL is deprecated. Further increments (<= 3 ) are not used.
NIF Specifications
W3C Conversion of NIF to ITS 2.0@en
W3C Conversion of NIF to ITS 2.0@en
URI http://www.w3.org/TR/its20/#nif-backconversion
Description The conversion from International TagSet (ITS) 2.0 to NIF is a possible basis for a natural language processing (NLP) application that creates, for example, named entity annotations. A non-normative algorithm to integrate these annotations into the original input document is given in Appendix G: Conversion NIF2ITS. Many decisions to be made in this algorithm depend on the particular NLP application being used.
