</SectionTitle>
    <Paragraph position="0"> With our work on German discourse connectives, the structure of their argument units, and the indicated rhetorical relations, we seek a better understanding of underlying linguistic issues on the one hand, and an easier way of developing rhetorical structure-annotated corpora for German texts on the other hand. For  this purpose, we present an annotation environment, including our ConAno tool, which helps human annotators to mark discourse connectives and their argument units by nding possible connectives and making suggestions on their estimated argument structure. We pointed out several challenges in the connective annotation process of German texts and introduced an XML based annotation scheme to handle the di culties. For one thing, the results of this step provide elobarate information about the structure of German texts with respect to discourse connectives, but furthermore they can be used as input to O'Donnell's RST Tool, in order to complete the annotation of the rhetorical tree structure. The overall scenario is then one of machine-assisted rhetorical structure annotation. Since ConAno is based on an external list of connectives (with associated syntactic labels and relations), the tool is not dedicated to one particular theory of discourse structure, let alone to a speci c set of relations. Furthermore, it can in principle deal with texts in various languages (it just relies on string matching between  input format connectives in the list and in the text), but we have so far used it only for German.</Paragraph>
