Semantic Annotation - VISL

Why higher-level Annotation
●
●
●
Corpora
– structurally and semantically annotated data provide a better
basis for linguistic research than raw text data
– lexicography: grammatical patterns rather than simple
collocations (verb complementation, modifiers etc.)
– training/learning of automatic NLP systems
Live annotation for language technology
– e.g. semantic distinctions for MT, or semantics for QA
How to annotate
– In our approach (CG). all information, also structural or
semantic, encoded as tags on tokens
– progressively, deducing syntactic structures from morphology
& PoS, and semantic structures from lexical types
