Complex connectives in German
Identifying the presence of coherence relations automatically is known to be a difﬁcult task for a number of reasons. One of the problems involved has so far received only little attention: Connectives (the primary source of information for relation analysis) can be complex, i.e. consist of several words that possibly are not adjacent, as in the case of “if .. then”. In this paper, we ﬁrst offer a classiﬁcation of complex connectives for German according to their structural properties, which leads us to propose six different groups. Furthermore, we describe how the structural properties can be captured in a formal “discourse marker lexicon”, which is in machine-readable (XML-based) form. Finally, we describe how this lexicon can in turn be employed for the task of automatic local coherence analysis, i.e. the identiﬁcation of individual relations between adjacent spans of text.
