From LinguisticAnnotation
Alembic Workbench is an SGML-based annotation system. Apart from the usual kinds of textual annotations, the workbench enables various kinds of specialized annotations including co-reference annotations (cf. the Message Understanding Conference markup rules), various kinds of user-defined inter-tag pointers, and (shortly) general template annotation (aka relations, frames, or events). The Alembic multi-lingual NLP system provides access to taggers for a wide variety of extraction levels, and applications have now been built for several languages. The software has a sophisticated visualisation component. It runs on Sun workstations and is freely distributed.
