Dieser Beitrag stellt das Forschungs- und Lehrkorpus Gesprochenes Deutsch (FOLK) und die Datenbank für Gesprochenes Deutsch (DGD) als Instrumente gesprächsanalytischer Arbeit vor. Nach einer allgemeinen Einführung in FOLK und DGD im zweiten Abschnitt werden im dritten Abschnitt die methodischen Beziehungen zwischen Korpuslinguistik und Gesprächsforschung und die Herausforde-rungen, die sich bei der Begegnung dieser beiden Herangehensweisen an authenti-sches Sprachmaterial stellen, kurz skizziert. Der vierte Abschnitt illustriert dann ausgehend vom Beispiel der Formel ich sag mal, wie eine korpus- und datenbankgesteuerte Analyse zur Untersuchung von Gesprächsphänomenen beitragen kann.
Machine learning methods offer a great potential to automatically investigate large amounts of data in the humanities. Our contribution to the workshop reports about ongoing work in the BMBF project KobRA (http://www.kobra.tu-dortmund.de) where we apply machine learning methods to the analysis of big corpora in language-focused research of computer-mediated communication (CMC). At the workshop, we will discuss first results from training a Support Vector Machine (SVM) for the classification of selected linguistic features in talk pages of the German Wikipedia corpus in DeReKo provided by the IDS Mannheim. We will investigate different representations of the data to integrate complex syntactic and semantic information for the SVM. The results shall foster both corpus-based research of CMC and the annotation of linguistic features in CMC corpora.
Language resources are often compiled for the purpose of variational analysis, such as studying differences between genres, registers, and disciplines, regional and diachronic variation, influence of gender, cultural context, etc. Often the sheer number of potentially interesting contrastive pairs can get overwhelming due to the combinatorial explosion of possible combinations. In this paper, we present an approach that combines well understood techniques for visualization heatmaps and word clouds with intuitive paradigms for exploration drill down and side by side comparison to facilitate the analysis of language variation in such highly combinatorial situations. Heatmaps assist in analyzing the overall pattern of variation in a corpus, and word clouds allow for inspecting variation at the level of words.
