1 Stand-off Annotation Further details and examples: Durusau and O’Donnell’s (2001) powerpoint presentation Thompson and McKelvie’s (1997) “Hyperlink semantics for standoff markup of read-only documents”. In Proceedings of SGML Europe '97

2 Corpus basics Required: structured, consistent, correct information for supporting empirical questions / hypothesis formation and hypothesis testing corpuscollection ‘raw’ texts source + annotation (annotated)

3 A frequent problem for sophisticated annotation: intersecting hierarchies These are some sentences with different kinds of things going on in them. This one is not very interesting. These are some sentences... This one is not very interesting.
