Der Beitrag untersucht vorhandene Lösungen und neue Möglichkeiten des Korpusausbaus aus Social Media- und internetbasierter Kommunikation (IBK) für das Deutsche Referenzkorpus (DEREKO). DEREKO ist eine Sammlung gegenwartssprachlicher Schriftkorpora am IDS, die der sprachwissenschaftlichen Öffentlichkeit über die Korpusschnittstellen COSMAS II und KorAP angeboten wird. Anhand von Definitionen und Beispielen gehen wir zunächst auf die Extensionen und Überlappungen der Konzepte Social Media, Internetbasierte Kommunikation und Computer-mediated Communication ein. Wir betrachten die rechtlichen Voraussetzungen für einen Korpusausbau aus Sozialen Medien, die sich aus dem kürzlich in relevanten Punkten reformierten deutschen Urheberrecht, aus Persönlichkeitsrechten wie der europäischen Datenschutz-Grundverordnung ergeben und stellen Konsequenzen sowie mögliche und tatsächliche Umsetzungen dar. Der Aufbau von Social Media-Korpora in großen Textmengen unterliegt außerdem korpustechnologischen Herausforderungen, die für traditionelle Schriftkorpora als gelöst galten oder gar nicht erst bestanden. Wir berichten, wie Fragen der Datenaufbereitung, des Korpus-Encoding, der Anonymisierung oder der linguistischen Annotation von Social Media Korpora für DEREKO angegangen wurden und welche Herausforderungen noch bestehen. Wir betrachten die Korpuslandschaft verfügbarer deutschsprachiger IBK- und Social Media-Korpora und geben einen Überblick über den Bestand an IBK- und Social Media-Korpora und ihre Charakteristika (Chat-, Wiki Talk- und Forenkorpora) in DEREKO sowie von laufenden Projekten in diesem Bereich. Anhand korpuslinguistischer Mikro- und Makro-Analysen von Wikipedia-Diskussionen im Vergleich mit dem Gesamtbestand von DEREKO zeigen wir charakterisierende sprachliche Eigenschaften von Wikipedia-Diskussionen auf und bewerten ihren Status als Repräsentant von IBK-Korpora.
Since 2013 representatives of several French and German CMC corpus projects have developed three customizations of the TEI-P5 standard for text encoding in order to adapt the encoding schema and models provided by the TEI to the structural peculiarities of CMC discourse. Based on the three schema versions, a 4th version has been created which takes into account the experiences from encoding our corpora and which is specifically designed for the submission of a feature request to the TEI council. On our poster we would present the structure of this schema and its relations (commonalities and differences) to the previous schemas.
This paper presents types and annotation layers of reply relations in computer- mediated communication (CMC). Reply relations hold between post units in CMC interactions and describe references from one given post to a previous post. We classify three types of reply relations in CMC interactions: first, technical replies, i. e. the possibility to reply directly to a previous post by clicking a ‘reply’ button; second, indentations, e. g. in wiki talk pages in which users insert their contributions in the existing talk page by indenting them and third, interpretative reply relations, i. e. the reply action is not realised formally but signalled by other structural or linguistics means such as address markers ‘@’, greetings, citations and/or Q-A structures. We take a look at existing practices in the description and representation of such relations in corpora and examples of chat, Wikipedia talk pages, Twitter and blogs. We then provide an annotation proposal that combines the different levels of description and representation of reply relations and which adheres to the schemas and practices for encoding CMC corpus documents within the TEI framework as defined by the TEI CMC SIG. It constitutes a prerequisite for correctly identifying higher levels of interactional relations such as dialogue acts or discussion trees.
This paper reports on the latest developments of the European Reference Corpus EuReCo and the German Reference Corpus in relation to three of the most important CMLC topics: interoperability, collaboration on corpus infrastructure building, and legal issues. Concerning interoperability, we present new ways to access DeReKo via KorAP on the API and on the plugin level. In addition we report about advancements in the EuReCo- and ICC-initiatives with the provision of comparable corpora, and about recent problems with license acquisitions and our solution approaches using an indemnification clause and model licenses that include scientific exploitation.
This paper analyses reply relations in computer-mediated communication (CMC), which occur between post units in CMC interactions and which describe references between posts. We take a look at existing practices in the description and annotation of such relations in chat, wiki talk, and blog corpora. We distinguish technical reply structures, indentation structures, and interpretative reply relations, which include reply relations induced by linguistic markers. We sort out the different levels of description and annotation that are involved and propose a solution for their combined representation within the TEI annotation framework.

Knowledge in textual form is always presented as visually and hierarchically structured units of text, which is particularly true in the case of academic texts. One research hypothesis of the ongoing project Knowledge ordering in texts - text structure and structure visualisations as sources of natural ontologies1 is that the textual structure of academic texts effectively mirrors essential parts of the knowledge structure that is built up in the text. The structuring of a modern dissertation thesis (e.g. in the form of an automatically generated table of contents - toes), for example, represents a compromise between requirements of the text type and the methodological and conceptual structure of its subject-matter. The aim of the project is to examine how visual-hierarchical structuring systems are constructed, how knowledge structures are encoded in them, and how they can be exploited to automatically derive ontological knowledge for navigation, archiving, or search tasks. The idea to extract domain concepts and semantic relations mainly from the structural and linguistic information gathered from tables of contents represents a novel approach to ontology learning.
This paper discusses current trends in DeReKo, the German Reference Corpus, concerning legal issues around the recent German copyright reform with positive implications for corpus building and corpus linguistics in general, recent corpus extensions in the genres of popular magazines, journals, historical texts, and web-based football reports. Besides, DeReKo is finally accessible via the new
corpus research platform KorAP, offering registered users several news features in comparison with its predecessor COSMAS II.
The paper reports on the results of a scientific colloquium dedicated to the creation of standards and best practices which are needed to facilitate the integration of language resources for CMC stemming from different origins and the linguistic analysis of CMC phenomena in different languages and genres. The key issue to be solved is that of interoperability – with respect to the structural representation of CMC genres, linguistic annotations metadata, and anonymization/pseudonymization schemas. The objective of the paper is to convince more projects to partake in a discussion about standards for CMC corpora and for the creation of a CMC corpus infrastructure across languages and genres. In view of the broad range of corpus projects which are currently underway all over Europe, there is a great window of opportunity for the creation of standards in a bottom-up approach.
