This paper deals with the creation of the first morphological treebank for German by merging two pre-existing linguistic databases. The first of these is the linguistic database CELEX which is a standard resource for German morphology. We build on its refurbished and modernized version. The second resource is GermaNet, a lexical-semantic network which also provides partial markup for compounds. We describe the state of the art and the essential characteristics of both databases and our latest revisions. As the merging involves two data sources with distinct annotation schemes, the derivation of the morphological trees for the unified resource is not trivial. We discuss how we overcome problems with the data and format, in particular how we deal with overlaps and complementary scopes. The resulting database comprises about 100,000 trees whose format can be chosen according to the requirements of the application at hand. In our discussion, we show some future directions for morphological treebanks. The Perl script for the generation of the data from the sources will be made publicly available on our website.
The paper deals with the use of ICH WEIß NICHT (‘I don’t know’) in German talk-in-interaction. Pursuing an Interactional Linguistics approach, we identify different interactional uses of ICH WEIß NICHT and discuss their relationship to variation in argument structure (SV (O), (O)VS, V-only). After ICH WEIß NICHT with full complementation, speakers emphasize their lack of knowledge or display reluctance to answer. In contrast, after variants without an object complement, in contrast, speakers display uncertainty about the truth of the following proposition or about its sufficiency as an answer. Thus, while uses with both subject and object tend to close a sequence or display lack of knowledge, responses without an object, in contrast, function as a prepositioned epistemic hedge or a pragmatic marker framing the following TCU. When ICH WEIß NICHT is used in response to a statement, it indexes disagreement (independently from all complementation patterns).

The naturalness of synthetic speech depends strongly on the prediction of appropriate prosody. For the present study the original annotation of the German speech database “Kiel Corpus of Read Speech” was extended automatically with syntactic features, word frequency, and syllable boundaries. Several classification and regression trees for predicting symbolic prosody features, postlexical phonological processes, duration, and F0 were trained on this database. The perceptual evaluation showed that the overall perceptual quality of the German text-to-speech system MARY can be significantly improved by training all models that contribute to prosody prediction on the same database. Furthermore, it showed that the error introduced by symbolic prosody prediction perceptually equals the error produced by a direct method that does not exploit any symbolic prosody features.
