A tool for multilevel corpus annotation


Atomic is a multilevel corpus annotation tool for the desktop, developed within the LinkType research project at the Friedrich Schiller University Jena.

Atomic is based on the Eclipse Rich Client Platform and written in Java.

Atomic is highly extendable, platform-independent, and supports different corpus formats.


Towards a corpus-based typology of clause linkage - An analytical framework and case studies on non-local dependencies (LinkType) is a DFG-funded linguistic research project that is jointly carried out by the universities of Zurich and Jena.

The project aims at statistically modeling linguistic variation in the area of complex sentences. It is based on the investigation of corpora from genealogically and geographically diverse languages that have been richly annotated.

About Atomic

Atomic is an open source annotation software for multi-level deep linguistic annotation of text corpora. It is based on the Eclipse RCP, a modular rich client platform. It features a graphical editor which can be controlled via keyboard, mouse, and command shell (with the native annotation language AtomicAL). It works on a concrete implementation of the generic graph-based meta-model Salt, and embeds its complementary conversion framework Pepper, allowing for n : m mapping between data formats (SaltNPepper homepage).
