The research project “German Today” aims to determine the amount of regional variation in (near-) standard German spoken by young and older educated adults, and to identify and locate the regional features. To this end, an extensive corpus of read and spontaneous speech is currently being compiled. German is a so-called pluricentric language. With our corpus we aim to determine whether national or regional standards really exist. Furthermore, the linguistic variation due to different contextual styles (read vs. spontaneous speech) shall be analysed. Finally, the corpus will enable us to investigate whether linguistic change has occurred in the domain of the German standard language. The main focus of all research questions is on phonetic variation (lexical variation is only of minor interest). Read and spontaneous speech of four secondary school students (aged seventeen to twenty) and two fifty- to sixt-year-olds is recorded in 160 cities throughout the German-speaking area of Europe. All participants read a number of short texts and word lists, name pictures, translate from English, and take part in a sociobiographic interview and a map task experiment. The resulting corpus will comprise over 1000 hours of orthographically and (in part) phonetically transcribed speech.
^This paper describes DeReKo (Deutsches Referenzkorpus), the Archive of General Reference Corpora of Contemporary Written German at the Institut für Deutsche Sprache (IDS) in Mannheim, and the rationale behind its development. We discuss its design, its legal background, how to access it, available metadata, linguistic annotation layers, underlying standards, ongoing developments, and aspects of using the archive for empirical linguistic research. The focus of the paper is on the advantages of DEREKO’s design as a primordial sample from which virtual corpora can be drawn for the specific purposes of individual studies. Both concepts, primordial sample and virtual corpus are explained and illustrated in detail. Furthermore, we describe in more detail how DEREKO deals with the fact that all its texts are subject to third parties’ intellectual property rights, and how it deals with the issue of replicability, which is particularly challenging given DEREKO’s dynamic growth and the possibility to construct from it an open number of virtual 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.
Data Mining with Shallow vs. Linguistic Features to Study Diversification of Scientific Registers
(2014)
We present a methodology to analyze the linguistic evolution of scientific registers with data mining techniques, comparing the insights gained from shallow vs. linguistic features. The focus is on selected scientific disciplines at the boundaries to computer science (computational linguistics, bioinformatics, digital construction, microelectronics). The data basis is the English Scientific Text Corpus (SCITEX) which covers a time range of roughly thirty years (1970/80s to early 2000s) (Degaetano-Ortlieb et al., 2013; Teich and Fankhauser, 2010). In particular, we investigate the diversification of scientific registers over time. Our theoretical basis is Systemic Functional Linguistics (SFL) and its specific incarnation of register theory (Halliday and Hasan, 1985). In terms of methods, we combine corpus-based methods of feature extraction and data mining techniques.
Newspapers became extremely popular in Germany during the 18th and 19th century, and thus increasingly influential for modern German. However, due to the lack of digitized historical newspaper corpora for German, this influence could not be analyzed systematically. In this paper, we introduce the Mannheim Corpus of Digital Newspapers and Magazines, which in its current release comprises 21 newspapers and magazines from the 18th and 19th century. With over 4.1 Mio tokens in about 650 volumes it currently constitutes the largest historical corpus dedicated to newspapers in German. We briefly discuss the prospect of the corpus for analyzing the evolution of news as a genre in its own right and the influence of contextual parameters such as region and register on the language of news. We then focus on one historically influential aspect of newspapers – their role in disseminating foreign words in German. Our preliminary quantitative results indeed indicate that newspapers use foreign words significantly more frequently than other genres, in particular belles lettres.
"FOLK is the ""Forschungs- und Lehrkorpus Gesprochenes Deutsch (FOLK)"" (eng.: research and teaching corpus of spoken German). The project has set itself the aim of building a corpus of German conversations which a) covers a broad range of interaction types in private, institutional and public settings, b) is sufficiently large and diverse and of sufficient quality to support different qualitative and quantitative research approaches, c) is transcribed, annotated and made accessible according to current technological standards, and d) is available to the scientific community on a sound legal basis and without unnecessary restrictions of usage. This paper gives an overview of the corpus design, the strategies for acquisition of a diverse range of interaction data, and the corpus construction workflow from recording via transcription an annotation to dissemination."
The Database for Spoken German (Datenbank für Gesprochenes Deutsch, DGD2, http://dgd.ids-mannheim.de) is the central platform for publishing and disseminating spoken language corpora from the Archive of Spoken German (Archiv für Gesprochenes Deutsch, AGD, http://agd.ids-mannheim.de) at the Institute for the German Language in Mannheim. The corpora contained in the DGD2 come from a variety of sources, some of them in-house projects, some of them external projects. Most of the corpora were originally intended either for research into the (dialectal) variation of German or for studies in conversation analysis and related fields. The AGD has taken over the task of permanently archiving these resources and making them available for reuse to the research community. To date, the DGD2 offers access to 19 different corpora, totalling around 9000 speech events, 2500 hours of audio recordings or 8 million transcribed words. This paper gives an overview of the data made available via the DGD2, of the technical basis for its implementation, and of the most important functionalities it offers. The paper concludes with information about the users of the database and future plans for its development.
Dieser Aufsatz befasst sich mit Fragen, die sich im Zusammenhang mit der Archivierung und öffentlichen Bereitstellungen von gesprächsanalytischen Daten (Audio- bzw. Videoaufnahmen und deren Transkriptionen) stellen. Er gibt zunächst einen Überblick über die Forschungsperspektiven, die eine verbesserte Praxis der Datenm•chivierung flir die Gesprächsforschung bieten würde, und nennt dann einige der wesentlichen Probleme, die in der derzeitigen Praxis der Schaffung solcher Archive im Wege stehen können. Anschließend werden vorhandene Lösungsansätze vorgestellt, die helfen können, diese Probleme zu überwinden.
This paper presents the Kicktionary, a multilingual (English — German - French) electronic lexical resource of the language of football. It explains how a corpus of football match reports was analysed according to the FrameNet and WordNet approaches and how the result of this analysis is presented to a dictionary user via a website
This paper presents the Kicktionary, a multilingual (English - German - French) electronic lexical resource of the language of football. In the Kicktionary, methods from corpus linguistics and two approaches to lexical semantics - the theory of frame semantics and the concept of semantic relations - are combined to construct a lexical resource in which the user can explore relationships between lexical units in various ways. This paper explains the theoretical background of the Kicktionary, sketches the data and methods which were used in its construction, and describes how the resulting resource is presented to users via a set of hyperlinked webpages.
This paper describes EXMARaLDA, an XML-based framework for the construction, dissemination and analysis of corpora of spoken language transcriptions. Departing from a prototypical example of a “partitur” (musical score) transcription, the EXMARaLDA “single timeline, multiple tiers” data model and format is presented alongside with the EXMARaLDA Partitur-Editor, a tool for inputting and visualizing such data. This is followed by a discussion of the interaction of EXMARaLDA with other frameworks and tools that work with similar data models. Finally, this paper presents an extension of the “single timeline, multiple tiers” data model and describes its application within the EXMARaLDA system.

Rescuing Legacy Data
(2008)
This paper discusses issues that arise in the transformation of electronic language data from outdated to modern, sustainable formats. We first describe the problem and then present four different cases in which corpora of spoken language were converted from legacy formats to an XML-based representation. For each of the four cases, we describe the conversion workflow and discuss the difficulties that we had to overcome. Based on this experience, we formulate some more general observations about transforming legacy data and conclude with a set of best practice recommendations for a more sustainable handling of language corpora.
This paper presents ongoing work on a multilingual (English, French, German) lexical resource of soccer language. The first part describes how lexicographic descriptions based on frame-semantic principles are derived from a partially aligned multilingual corpus of soccer match reports. The remainder of the paper then discusses how different types of ontological knowledge are linked to this resource in order to provide an access structure to the resulting dictionary. It is argued that linking lexical resources and ontologies in such a way provides novel ways to a dictionary user of navigating a domain vocabulary

This paper presents EXMARaLDA, a system for the computer-assisted creation and analysis of spoken
language corpora. The first part contains some general observations about technological and methodological requirements for doing corpus-based pragmatics. The second part explains the systems architecture and gives an overview of its most important software components a transcription editor, a corpus management tool and a corpus query tool. The last part presents some corpora which have been or are currently being compiled with the help of EXMARaLDA.
Spoken language corpora— as used in conversation analytic research, language acquisition studies and dialectology— pose a number of challenges that are rarely addressed by corpus linguistic methodology and technology. This paper starts by giving an overview of the most important methodological issues distinguishing spoken language corpus workfrom the work with written data. It then shows what technological challenges these methodological issues entail and demonstrates how they are dealt with in the architecture and tools of the EXMARaLDA system.
This paper presents FOLKER, an annotation tool developed for the efficient transcription of natural, multi-party interaction in a conversation analysis framework. FOLKER is being developed at the Institute for German Language in and for the FOLK project, whose aim is the construction of a large corpus of spoken present-day German, to be used for research and teaching purposes. FOLKER builds on the experience gained with multi-purpose annotation tools like ELAN and EXMARaLDA, but attempts to improve transcription efficiency by restricting and optimizing both data model and tool functionality to a single, well-defined purpose. This paper starts with a description of the GAT transcription conventions and the data model underlying the tool. It then gives an overview of the tool functionality and compares this functionality to that of other widely used tools.
This contribution addresses the workshop topic of “standardising policies within eHumanities infrastructures”. It relates 10 years of experience with language resource standards, gained in the development of EXMARaLDA, a system for the construction and exploitation of spoken language corpora. Section 2 gives an overview of the EXMARaLDA system focussing on its relationship with existing and evolving standards for language resources. Section 3 presents the HIAT system as an example of an established community practice. Section 4 then addresses several issues that where encountered when trying to bring together HIAT, EXMARaLDA and the wider standard world.
We give an overview of the content and the technical background of a number of corpora which were developed in various projects of the Research Centre on Multilingualism (SFB 538) between 1999 and 2011 and which are now made available to the scientific community via the Hamburg Centre for Language Corpora.
We present some recent and planned future developments in EXMARaLDA, a system for creating, managing, analysing and publishing spoken language corpora. The new functionality concerns the areas of transcription and annotation, corpus management, query mechanisms, interoperability and corpus deployment. Future work is planned in the areas of automatic annotation, standardisation and workflow management.
High word frequency and neighborhood density contribute to the accuracy and speed of word production in English adults (e.g., Vitevitch & Sommers 2003), and characterize early words in child English (e.g., Storkel 2004). The present study investigated a speech corpus of child German (ages 2;00-3;00) to further the understanding of the influence of frequency and density on production. Results for four children suggest that, contrary to English, words produced early are not from denser neighborhoods in an adult lexicon than later words. As in English, frequent words are produced before less frequent words. Implications on theory and methodology are discussed.
Die „Datenbank für Gesprochenes Deutsch“ (DGD2) ist ein Korpusmanagementsystem im Archiv für Gesprochenes Deutsch (AGD) am Institut für Deutsche Sprache. Über die DGD2 werden Teilbestände des Archivs (Audioaufnahmen gesprochener Sprache, sowie zugehörige Metadaten, Transkripte und Zusatzmaterialien) der wissenschaftlichen Öffentlichkeit online zur Verfügung gestellt. Sie enthält derzeit knapp 9000 Datensätze aus 18 Korpora. Die DGD2 ist das Nachfolgesystem der älteren „Datenbank Gesprochenes Deutsch“ (ab hier: DGD1, siehe Fiehler/Wagener 2005). Da die DGD1 aufgrund ihrer technischen Realisierung mittelfristig kaum wartbar und erweiterbar ist, wurde die DGD2 auf eine neue technische Basis gestellt und stellt insofern keine direkte Weiterentwicklung der DGD1 dar, sondern eine Neuentwicklung, die freilich einen Großteil der Datenbestände und Funktionalität mit der DGD1 teilt. Die DGD2 wurde der Öffentlichkeit erstmals in einem Beta-Release im Februar 2012 zugänglich gemacht. In diesem Beitrag stellen wir die Datenbestände, die technische Realisierung sowie die Funktionalität des ersten offiziellen Release der DGD2 vom Dezember 2012 vor. Wir schließen mit einem Ausblick auf geplante Weiterentwicklungen.
Eine angemessene, sachgemäße Diskussion über Stärken und Schwächen, Möglichkeiten und Grenzen der Korpuslinguistik ist überschattet von vielen Mythen, die sich mittlerweile eingebürgert haben und die in vielen Diskussionen – gerade unter Linguisten – immer wieder aufkommen. An dieser Stelle möchten wir einige der verbreitetsten Mythen zusammenstellen und die Hintergründe aus dieser korpuslinguistischen Perspektive erörtern.
