ConnAnno (Stede and Heintze 2004) is a Java tool for semi-automatic annotation of connectives and their arguments.

Potential preposed or postposed modifiers, if any, of the connective are also highlighted (in a different color). The user moves with the mouse from one connective to the next and

The current version of ConnAnno only handles German connectives (via DimLex; Stede and Umbach 1998), but you’d only need a different lexicon file to handle other languages as well. A version for English is in preparation.
