Zum Verschmelzungsverhalten von definitem Artikel und Präposition in der Schriftsprache des Deutschen liegen bereits diverse Erkenntnisse vor, wohingegen die Kenntnislage für die gesprochene Sprache noch unzureichend ist. Die vorliegende Untersuchung widmet sich diesem Desiderat und analysiert Präposition-Artikel-Kombinationen anhand von Daten aus FOLK, um die linguistische Beschreibung dieser Struktur voranzutreiben. In der durchgeführten Korpusanalyse werden die Auftretenshäufigkeiten synthetischer und analytischer Präposition-Artikel-Kombinationen verglichen und Gebrauchsbesonderheiten auf syntaktisch-lexikalischer und pragmatischer Ebene herausgearbeitet.
Seit der Forschung große Datenmengen und Rechenkapazitäten zur Verfügung stehen arbeitet auch die Sprachwissenschaft zunehmend datengeleitet. Datengeleitete Forschung geht nicht von einer Hypothese aus, sondern sucht nach statistischen Auffälligkeiten in den Daten. Sprache wird dabei oft stark vereinfacht als lineare Abfolge von Wörtern betrachtet. Diese Studie zeigt erstmals, wie der zusätzliche Einbezug syntaktischer Annotationen dabei hilft, sprachliche Strukturen des Deutschen besser zu erfassen.
Als Anwendungsbeispiel dient der Vergleich der Wissenschaftssprachen von Linguistik und Literaturwissenschaft. Die beiden Fächer werden oft als Teildisziplinen der Germanistik zusammengefasst. Ihre wissenschaftliche Praxis unterscheidet sich jedoch systematisch hinsichtlich Forschungsdaten, Methoden und Erkenntnisinteressen, was sich auch in den Wissenschaftssprachen niederschlägt.
So far, Sepedi negations have been considered more from the point of view of lexicographical treatment. Theoretical works on Sepedi have been used for this purpose, setting as an objective a neat description of these negations in a (paper) dictionary. This paper is from a different perspective: instead of theoretical works, corpus linguistic methods are used: (1) a Sepedi corpus is examined on the basis of existing descriptions of the occurrences of a relevant verb, looking at its negated forms from a purely prescriptive point of view; (2) a "corpus-driven" strategy is employed, looking only for sequences of negation particles (or morphemes) in order to list occurring constructions, without taking into account the verbs occurring in them, apart from their endings. The approach in (2) is only intended to show a possible methodology to extend existing theories on occurring negations. We would also like to try to help lexicographers to establish a frequency-based order of entries of possible negation forms in their dictionaries by showing them the number of respective occurrences. As with all corpus linguistic work, however, we must regard corpus evidence not as representative, but as tendencies of language use that can be detected and described. This is especially true for Sepedi, for which only few and small corpora exist. This paper also describes the resources and tools used to create the necessary corpus and also how it was annotated with part of speech and lemmas. Exploring the quality of available Sepedi part-of-speech taggers concerning verbs, negation morphemes and subject concords may be a positive side result.
Dieser Beitrag beschreibt die Motivation und Ziele hinter der Initiative Europäisches Referenzkorpus EuReCo. Ausgehend von den Desiderata, die sich aufgrund der Defizite verfügbarer Forschungsdaten wie monolinguale Korpora, Parallelkorpora und Vergleichskorpora für den Sprachvergleich ergeben, werden die bisherigen und die laufenden Arbeiten im Rahmen von EuReCo präsentiert und anhand vergleichender deutsch-rumänischer Kookkurrenzanalysen neue Perspektiven für kontrastive Korpuslinguistik, die die EuReCo-Initiative öffnet, skizziert.
Kontrastive Korpuslinguistik versteht sich als eine Bezeichnung für sprachvergleichende Studien, deren Ergebnisse mit Analysen sprachlicher Daten erreicht und empirisch fundiert sind. Die Bezeichnung contrastive corpus linguistics für eine neue, sich entwickelnde Disziplin wurde 1996 von Karin Aijmer und Bengt Altenberg (Schmied 2009: 1142) eingeführt. Der Einsatz der sprachlichen Korpora bei der Beschreibung kontrastiver Studien bedeutet in den 1990er-Jahren für die kontrastive Linguistik eine Wiederbelebung, nachdem die weit gesteckten Ziele und Hoffnungen in den 50er- und 60er-Jahren, die mit der Fremdsprachendidaktik zusammenhingen, vor etwa 50 Jahren aufgegeben wurden.
Kontrastive Korpuslinguistik

The QUEST (QUality ESTablished) project aims at ensuring the reusability of audio-visual datasets (Wamprechtshammer et al., 2022) by devising quality criteria and curating processes. RefCo (Reference Corpora) is an initiative within QUEST in collaboration with DoReCo (Documentation Reference Corpus, Paschen et al. (2020)) focusing on language documentation projects. Previously, Aznar and Seifart (2020) introduced a set of quality criteria dedicated to documenting fieldwork corpora. Based on these criteria, we establish a semi-automatic review process for existing and work-in-progress corpora, in particular for language documentation. The goal is to improve the quality of a corpus by increasing its reusability. A central part of this process is a template for machine-readable corpus documentation and automatic data verification based on this documentation. In addition to the documentation and automatic verification, the process involves a human review and potentially results in a RefCo certification of the corpus. For each of these steps, we provide guidelines and manuals. We describe the evaluation process in detail, highlight the current limits for automatic evaluation and how the manual review is organized accordingly.
Metadata provides important information relevant both to finding and understanding corpus data. Meaningful linguistic data requires both reasonable annotations and documentation of these annotations. This documentation is part of the metadata of a dataset. While corpus documentation has often been provided in the form of accompanying publications, machinereadable metadata, both containing the bibliographic information and documenting the corpus data, has many advantages. Metadata standards allow for the development of common tools and interfaces. In this paper I want to add a new perspective from an archive’s point of view and look at the metadata provided for four learner corpora and discuss the suitability of established standards for machine-readable metadata. I am are aware that there is ongoing work towards metadata standards for learner corpora. However, I would like to keep the discussion going and add another point of view: increasing findability and reusability of learner corpora in an archiving context.

This paper describes a method for extracting collocation data from text corpora based on a formal definition of syntactic structures, which takes into account not only the POS-tagging level of annotation but also syntactic parsing (syntactic treebank model) and introduces the possibility of controlling the canonical form of extracted collocations based on statistical data on forms with different properties in the corpus. Specifically, we describe the results of extraction from the syntactically tagged Gigafida 2.1 corpus. Using the new method, 4,002,918 collocation candidates in 81 syntactic structures were extracted. We evaluate the extracted data sample in more detail, mainly in relation to properties that affect the extraction of canonical forms: definiteness in adjectival collocations, grammatical number in noun collocations, comparison in adjectival and adverbial collocations, and letter case (uppercase and lowercase) in canonical forms. The conclusion highlights the potential of the methodology used for the grammatical description of collocation and phrasal syntax and the possibilities for improving the model in the process of compilation of a digital dictionary database for Slovene.
Eine korpuslinguistische Untersuchung mit umfassender Analyse der häufiger vorkommenenden Adverbbildungsmuster des Deutschen legt nahe, dass die Sättigung des internen Argumentplatzes eines ursprünglich relationalen Ausdrucks eine wichtige Rolle bei der Adverbproduktion spielt (Brandt 2020). Eine genauere Betrachtung der Unterschiede zwischen -ermaßen- vs. -erweise-Adverbien deutet auf eine grammatische Unterscheidung zwischen Satzadverbien und Adverbien der Art und Weise: Im Fall von -ermaßen erfolgt die Sättigung über Token-Reflexivität, während der interne Slot von -erweise- Bildungen über häufigere und möglicherweise expansive Mechanismen geschlossen wird. Darüber hinaus fördert die pleonastische Qualität von Bildungen auf der Basis gerundivaler Partizipien die Produktivität von -erweise Adverbien.
This paper describes a method for automatic identification of sentences in the Gigafida corpus containing multi-word expressions (MWEs) from the list of 5,242 phraseological units, which was developed on the basis of several existing open-access lexical resources for Slovene. The method is based on a definition of MWEs, which includes information on two levels of corpus annotation: syntax (dependency parsing) and morphology (POS tagging), together with some additional statistical parameters. The resulting lexicon contains 12,358 sentences containing MWEs extracted from the corpus. The extracted sentences were analysed from the lexicographic point of view with the aim of establishing canonical forms of MWEs and semantic relations between them in terms of variation, synonymy, and antonymy.
Ziel dieser Arbeit war es, eine Software zu entwickeln, die quantitative und qualitative korpuslinguistische Methoden miteinander verbindet. Die Gesamtarbeit besteht daher aus zwei Teilen: einer Open-Source-Software und dem schriftlichen Teil. Der hier vorgelegte schriftliche Teil ist eine vollständige Dokumentation (Handbuch), ergänzt um eigene Publikationen, die im Rahmen des Dissertationsprojekts entstanden. In Kapitel 1.2 Korpora und beispielhafte Fragestellungen (S. 8) erfolgt eine Illustration beispielhafter Forschungsfragen anhand bereitgestellter und im Corpus- Explorer integrierter Korpora. Außerdem werden unter "?? ?? (S. ??)" Analysen mit verschiedensten prototypischen Forschungsfragen verknüpft, die sowohl quantitative als auch qualitative Perspektiven einnehmen. Der CorpusExplorer wurde besonders nutzerfreundlich gestaltet. Dabei ist die Zielgruppe der Software sehr breit defniert: Die Nutzung soll sowohl in der Forschung als auch in der Lehre möglich sein. Daher richtet sich der CorpusExplorer gleichermaßen an Studierende und Forschende mit ihren jeweils spezifschen Bedürfnissen. Die Nutzung für die Forschung zeigt sich (A) an den integrierten Artikeln sowie daran, dass (B) andere Forschende den CorpusExplorer bereits für ihre Arbeit aufgegriffen haben. Der Nutzen für die Lehre wurde mehrfach selbst erprobt und optimiert. Im Lehr-Einsatz ist es wichtig, dass Korpora mit wenigen Mausklicks analysefertig sind und verschiedene Analysen und Visualisierungen direkt genutzt werden können. Studierende erhalten so die Möglichkeit, eigenes Korpusmaterial direkt und selbst auszuwerten. Für Forschende bietet der CorpusExplorer ein sehr breites Funktionsspektrum. Im Vergleich zu anderer (öffentlich verfügbarer) korpuslinguistischer Software verfügt er aktuell über das wohl breiteste Anwendungsspektrum (51 Analysemodule (inkl. weiterentwickelter Verfahren), über 100 unterstützte Dateiformate für Im- und Export, unterschiedliche Tagger mit 69 unterstützten Sprachmodellen). Er kann so in bestehende Skripte, Toolchains und Workflows für sehr unterschiedliche Forschungsfragen integriert werden. Im CorpusExplorer wurden nicht nur bestehende Funktionen gebündelt, es wurden auch bisherige Verfahren weiterentwickelt. Hierzu zählen z. B. (1) die Entwicklung einer eigenen, an korpuslinguistischen Bedürfnissen ausgerichteten Datenbank- Struktur, (2) die Weiterentwicklung bzw. Optimierung des Verfahrens der Kookkurrenz- Analyse hin zu einer quantitativen Kookkurrenz-Analyse (keine Parameter wie Suchfenstergröße oder Suchwort nötig, Berechnung aller Kookkurrenzen zu allen Token in einem Korpus) und (3) die Verknüpfung unterschiedlicher Analyseressourcen, wie z. B. der NGram- und der Kookkurrenz-Analyse.
When comparing different tools in the field of natural language processing (NLP), the quality of their results usually has first priority. This is also true for tokenization. In the context of large and diverse corpora for linguistic research purposes, however, other criteria also play a role – not least sufficient speed to process the data in an acceptable amount of time. In this paper we evaluate several state of the art tokenization tools for German – including our own – with regard to theses criteria. We conclude that while not all tools are applicable in this setting, no compromises regarding quality need to be made.
This thesis is a corpus linguistic investigation of the language used by young German speakers online, examining lexical, morphological, orthographic, and syntactic features and changes in language use over time. The study analyses the language in the Nottinghamer Korpus deutscher YouTube‐Sprache ("Nottingham corpus of German YouTube language", or NottDeuYTSch corpus), one of the first large corpora of German‐language comments taken from the videosharing website YouTube, and built specifically for this project. The metadatarich corpus comprises c.33 million tokens from more than 3 million comments posted underneath videos uploaded by mainstream German‐language youthorientated YouTube channels from 2008‐2018.
The NottDeuYTSch corpus was created to enable corpus linguistic approaches to studying digital German youth language (Jugendsprache), having identified the need for more specialised web corpora (see Barbaresi 2019). The methodology for compiling the corpus is described in detail in the thesis to facilitate future construction of web corpora. The thesis is situated at the intersection of Computer‐Mediated Communication (CMC) and youth language, which have been important areas of sociolinguistic scholarship since the 1980s, and explores what we can learn from a corpus‐driven, longitudinal approach to (online) youth language. To do so, the thesis uses corpus linguistic methods to analyse three main areas:
1. Lexical trends and the morphology of polysemous lexical items. For this purpose, the analysis focuses on geil, one of the most iconic and productive words in youth language, and presents a longitudinal analysis, demonstrating that usage of geil has decreased, and identifies lexical items that have emerged as potential replacements. Additionally, geil is used to analyse innovative morphological productiveness, demonstrating how different senses of geil are used as a base lexeme or affixoid in compounding and derivation.
2. Syntactic developments. The novel grammaticalization of several subordinating conjunctions into both coordinating conjunctions and discourse markers is examined. The investigation is supported by statistical analyses that demonstrate an increase in the use of non‐standard syntax over the timeframe of the corpus and compares the results with other corpora of written language.
3. Orthography and the metacommunicative features of digital writing. This analysis identifies orthographic features and strategies in the corpus, e.g. the repetition of certain emoji, and develops a holistic framework to study metacommunicative functions, such as the communication of illocutionary force, information structure, or the expression of identities. The framework unifies previous research that had focused on individual features, integrating a wide range of metacommunicative strategies within a single, robust system of analysis.
By using qualitative and computational analytical frameworks within corpus linguistic methods, the thesis identifies emergent linguistic features in digital youth language in German and sheds further light on lexical and morphosyntactic changes and trends in the language of young people over the period 2008‐2018. The study has also further developed and augmented existing analytical frameworks to widen the scope of their application to orthographic features associated with digital writing.
Enabling appropriate access to linguistic research data, both for many researchers and for innovative research applications, is a challenging task. In this chapter, we describe how we address this challenge in the context of the German Reference Corpus DeReKo and the corpus analysis platform KorAP. The core of our approach, which is based on and tightly integrated into the CLARIN infrastructure, is to offer access at different levels. The graduated access levels make it possible to find a low-loss compromise between the possibilities opened up and the costs incurred by users and providers for each individual use case, so that, viewed over many applications, the ratio between effort and results achieved can be effectively optimized. We also report on experiences with the current state of this approach.
Based on the privative derivational suffix -los, we test statements found in the literature on word formation using a – at least in this field – novel empirical basis: a list of affective-emotional ratings of base nouns and associated -los derivations. In addition to a frequency analysis based on the German Reference Corpus, we show that, in general, emotional polarity (so-called valence, positive vs. negative emotions) is reversed by suffixation with -los. This change is stronger for more polarized base nouns. The perceived intensity of emotion (so-called arousal) is generally lower for -los derivations than for base nouns. Finally, to capture the results theoretically, we propose a prototypical -los construction in the framework of Construction Morphology.

This contribution aims to show the necessity of working in the development of multilingual corpora and appropriate tools for multilingual contrastive studies. We take the corpus of the lexicographical project COMBIDIGILEX as example to show, how difficultit is to build a suitable data basis to study and compare linguistic phenomena in German, Spanish and Portuguese. Despite the availability of big reference corpora for the three languages (at least for written language), it is not able to obtain a comparable data basis from, because the mentioned corpora are created according to different requirements and they are also powered by disparate information systems and analyse tools. To break the status quo, we plead for increasing research infrastructures by means of compatible language technology and sharing data.

Dictionaries are often a reflection of their time; their respective (socio-)historical context influences how the meaning of certain lexical units is described. This also applies to descriptions of personal terms such as man or woman. Lexicographers have a special responsibility to comprehensively investigate current language use before describing it in the dictionary. Accordingly, contemporary academic dictionaries are usually corpus-based. However, it is important to acknowledge that language is always embedded in cultural contexts. Our case study investigates differences in the linguistic contexts of the use of man and woman, drawing from a range of language collections (in our case fiction books, popular magazines and newspapers). We explain how potential differences in corpus construction would therefore influence the “reality”1 depicted in the dictionary. In doing so, we address the far-reaching consequences that the choice of corpus-linguistic basis for an empirical dictionary has on semantic descriptions in dictionary entries.
Furthermore, we situate the case study within the context of gender-linguistic issues and discuss how lexicographic teams can engage with how dictionaries might perpetuate traditional role concepts when describing language use.
