Classical null hypothesis significance tests are not appropriate in corpus linguistics, because the randomness assumption underlying these testing procedures is not fulfilled. Nevertheless, there are numerous scenarios where it would be beneficial to have some kind of test in order to judge the relevance of a result (e.g. a difference between two corpora) by answering the question whether the attribute of interest is pronounced enough to warrant the conclusion that it is substantial and not due to chance. In this paper, I outline such a test.
This paper presents the current results of an ongoing research project on corpus distribution of prepositions and pronouns within Polish preposition-pronoun contractions. The goal of the project is to provide a quantitative description of Polish preposition-pronoun contractions taking into consideration morphosyntactic properties of their components. It is expected that the results will provide a basis for a revision of the traditionally assumed inflectional paradigms of Polish pronouns and, thus, for a possible remodeling of these paradigms. The results of corpus-based investigations of the distribution of prepositions within preposition-pronoun contractions can be used for grammar-theoretical and lexicographic purposes.
In the first volume of Corpus Linguistics and Linguistic Theory, Gries (2005. Null-hypothesis significance testing of word frequencies: A follow-up on Kilgarriff. Corpus Linguistics and Linguistic Theory 1(2). doi:10.1515/ cllt.2005.1.2.277. http://www.degruyter.com/view/j/cllt.2005.1.issue-2/cllt.2005. 1.2.277/cllt.2005.1.2.277.xml: 285) asked whether corpus linguists should abandon null-hypothesis significance testing. In this paper, I want to revive this discussion by defending the argument that the assumptions that allow inferences about a given population – in this case about the studied languages – based on results observed in a sample – in this case a collection of naturally occurring language data – are not fulfilled. As a consequence, corpus linguists should indeed abandon null-hypothesis significance testing.
We present a corpus-driven approach to the study of multi-word expressions, which constitute a significant part of. As a data basis, we use collocation profiles computed from DeReKo (Deutsches Referenzkorpus), the largest available collection of written German which has approximately two billion word tokens and is located at the Institute for the German Language (IDS). We employ a strongly usage-based approach to multi-word expressions, which we think of as conventionalised patterns in language use that manifest themselves in recurrent syntagmatic patterns of words. They are defined by their distinct function in language. To find multi-word expressions, we allow ourselves to be guided by corpus data and statistical evidence as much as possible, making interpretative steps carefully and in a monitored fashion. We develop a procedure of interpretation that leads us from the evidence of collocation profiles to a collection of recurrent word patterns and finally to multi-word expressions. When building up a collection of multi-word expressions in this fashion, it becomes clear that the expressions can be defined on different levels of generalisation and are interrelated in various ways. This will be reflected in the documentation and presentation of the findings. We are planning to add annotation in a way that allows grouping the multi-word expressions according to different features and to add links between them to reflect their relationships, thus constructing a network of multi-word expressions.
Es gibt viele linguistische Forschungsfragen, für deren Beantwortung man Korpusdaten qualitativ und quantitativ auswerten möchte. Beide Auswertungsmethoden können sich auf den Korpustext, aber auch auf Annotationsebenen beziehen. Jede Art von Annotation, also Kategorisierung, stellt einen kontrollierten und notwendigen Informationsverlust dar. Das bedeutet, dass jede Art von Kategorisierung auch eine Interpretation der Daten ist. In den meisten großen Korpora wird zu jeder vorgesehenen Annotationsebene, wie z. B. Wortart-Ebene oder Lemma-Ebene, genau eine Interpretation angeboten. In den letzten Jahren haben sich neben den großen, ,,flach“ annotierten Korpora Korpusmodelle herausgebildet, mit denen man konfligierende Informationen kodieren kann, die so genannten Mehrebenen-Modelle (multilevel standoff corpora), in denen alle Annotationsebenen unabhängig vom Text gespeichert werden und nur auf bestimmte Textanker verweisen. Ich argumentiere anhand der Fehlerannotation in einem Lernerkorpus dafür, dass zumindest Korpora, in denen es stark variierende Annotationsbedürfnisse und umstrittene Analysen geben kann, davon profitieren, in Mehrebenen-Modellen kodiert zu werden.
In the NLP literature, adapting a parser to new text with properties different from the training data is commonly referred to as domain adaptation. In practice, however, the differences between texts from different sources often reflect a mixture of domain and genre properties, and it is by no means clear what impact each of those has on statistical parsing. In this paper, we investigate how differences between articles in a newspaper corpus relate to the concepts of genre and domain and how they influence parsing performance of a transition-based dependency parser. We do this by applying various similarity measures for data point selection and testing their adequacy for creating genre-aware parsing models.
Ein vergleichender Blick auf die Buchstabenverteilung im Anlaut und im Auslaut von Rufnamen, Familiennamen und Appellativa zeigt, dass die Rufnamen hinsichtlich ihrer Anlaut- und Auslautstruktur besonders distinkt sind. Familiennamen hingegen zeigen sowohl Charakteristika der alphabetischen Verteilung von Appellativen wie von Rufnamen, sind also weniger distinkt, durch die Mischung dieser Charakteristika aber auch als Gruppe gekennzeichnet.
In diesem Beitrag versuchen wir darzulegen, unter welchen Umständen introspektive Urteile objektive, quantifizierbare, und empirisch adäquate linguistische Daten sein können. Dazu skizzieren wir, wie die Resultate unserer experimentell erhobenen, relativen Urteilsstudien aussehen, und argumentieren, dass sie eine unverzichtbare Evidenzquelle für die Syntax bilden, weil sie Einsichten in die Architektur der Grammatik erlauben, die mit anderen Mitteln nicht möglich sind.
Die Arbeiten in diesem Band zeigen anhand ausgewählter morphosyntaktischer Phänomene exemplarisch auf, wie ein korpuslinguistischer Zugang genutzt werden kann, um die Vielfalt und Variabilität des Sprachgebrauchs in einer größeren Detailschärfe zu beschreiben, als dies bisher möglich war. Ausgangspunkt ist die Überlegung, dass sprachliche Variation als integraler Bestandteil der (Standard-)Sprache anzusehen ist und somit auch deskriptiv erfasst werden muss. Dabeigeht es zunächst um eine möglichst genaue Beschreibung der Verteilung und Häufigkeit verschiedener Ausprägungen ausgewählter Variablen. Eine umfassende Beschreibung eines Variationsphänomens beinhaltet zudem die Ermittlung und Gewichtung der Faktoren, die die Distribution der Variantensteuern. In diesem Zusammenhang werden Hypothesen aus der einschlägigen Forschungsliteratur unter Verwendung moderner statistischer Verfahren überprüft. Darüber hinaus enthalten die vorliegenden Studien eine explorative Komponente, die sich mit der Aufdeckung neuer Muster, Regularitäten und linguistischer Zusammenhänge befasst. Dabei werden verschiedene korpuslinguistische und statistische Ansätze und Verfahren erprobt und evaluiert.
Large-scale empirical evidence indicates a fascinating statistical relationship between the estimated number of language users and its linguistic and statistical structure. In this context, the linguistic niche hypothesis argues that this relationship reflects a negative selection against morphological paradigms that are hard to learn for adults, because languages with a large number of speakers are assumed to be typically spoken and learned by greater proportions of adults. In this paper, this conjecture is tested empirically for more than 2000 languages. The results question the idea of the impact of non-native speakers on the grammatical and statistical structure of languages, as it is demonstrated that the relative proportion of non-native speakers does not significantly correlate with either morphological or information-theoretic complexity. While it thus seems that large numbers of adult learners/speakers do not affect the (grammatical or statistical) structure of a language, the results suggest that there is indeed a relationship between the number of speakers and (especially) information-theoretic complexity, i.e. entropy rates. A potential explanation for the observed relationship is discussed.
This paper explores how attitudes affect the seemingly objective process of counting speakers of varieties using the example of Low German, Germany’s sole regional language. The initial focus is on the basic taxonomy of classifying a variety as a language or a dialect. Three representative surveys then provide data for the analysis: the Germany Survey 2008, the Northern Germany Survey 2016, and the Germany Survey 2017. The results of these surveys indicate that there is no consensus concerning the evaluation of Low German’s status and that attitudes towards Low German are related to, for example, proficiency in the language. These attitudes are shown to matter when counting speakers of Low German and investigating the status it has been accorded.
The article investigates the conditions under which the w-relativizer was appears instead of the d-relativzer das in German relative clauses. Building on Wiese 2013, we argue that was constitutes the elsewhere case that applies when identification with the antecedent cannot be established by syntactic means via upward agreement with respect to phi-features. Corpuslinguistic results point to the conclusion that this is the case whenever there is no lexical nominal in the antecedent that, following Geach 1962 and Baker 2003, supplies a criterion of identity needed to establish sameness of reference between the antecedent and the relativizer.
Sprecher haben (oft unbewusste) Meinungen und Einstellungen zu Sprachen und Varietäten. Ein Weg, solche Spracheinstellungen zu erfassen, führt über quantitative Verfahren (Fragebogen mit offenen und geschlossenen Fragen), mit denen man Daten großer Gruppen – im Idealfall repräsentativ – erheben kann. Im Beitrag werden solche Erhebungen, die am Institut für Deutsche Sprache durchgeführt wurden, vorgestellt, und es werden zwei Instrumente der Spracheinstellungsforschung, die dabei zum Einsatz kamen, naher erläutert: das Allgemeine Sprachbewertungsinstrument (ASBI) und die Attitudes-Towards-Languages-Skala (AToL). Außerdem wird gezeigt, wie dialektometrische Auswertungs- und Visualisierungsverfahren auf Einstellungsdaten angewendet werden können.

In order to demonstrate why it is important to correctly account for the (serial dependent) structure of temporal data, we document an apparently spectacular relationship between population size and lexical diversity: for five out of seven investigated languages, there is a strong relationship between population size and lexical diversity of the primary language in this country. We show that this relationship is the result of a misspecified model that does not consider the temporal aspect of the data by presenting a similar but nonsensical relationship between the global annual mean sea level and lexical diversity. Given the fact that in the recent past, several studies were published that present surprising links between different economic, cultural, political and (socio-)demographical variables on the one hand and cultural or linguistic characteristics on the other hand, but seem to suffer from exactly this problem, we explain the cause of the misspecification and show that it has profound consequences. We demonstrate how simple transformation of the time series can often solve problems of this type and argue that the evaluation of the plausibility of a relationship is important in this context. We hope that our paper will help both researchers and reviewers to understand why it is important to use special models for the analysis of data with a natural temporal ordering.
Quantitativ ausgerichtete empirische Linguistik hat in der Regel das Ziel, grose Mengen sprachlichen Materials auf einmal in den Blick zu nehmen und durch geeignete Analysemethoden sowohl neue Phanomene zu entdecken als auch bekannte Phanomene systematischer zu erforschen. Das Ziel unseres Beitrags ist es, anhand zweier exemplarischer Forschungsfragen methodisch zu reflektieren, wo der quantitativ-empirische Ansatz fur die Analyse lexikalischer Daten wirklich so funktioniert wie erhofft und wo vielleicht sogar systembedingte Grenzen liegen. Wir greifen zu diesem Zweck zwei sehr unterschiedliche Forschungsfragen heraus: zum einen die zeitnahe Analyse von produktiven Wortschatzwandelprozessen und zum anderen die Ausgleichsbeziehung von Wortstellungsvs. Wortstrukturregularitat in den Sprachen der Welt. Diese beiden Forschungsfragen liegen auf sehr unterschiedlichen Abstraktionsebenen. Wir hoffen aber, dass wir mit ihnen in groser Bandbreite zeigen konnen, auf welchen Ebenen die quantitative Analyse lexikalischer Daten stattfinden kann. Daruber hinaus mochten wir anhand dieser sehr unterschiedlichen Analysen die Moglichkeiten und Grenzen des quantitativen Ansatzes reflektieren und damit die Interpretationskraft der Verfahren verdeutlichen.
This contribution presents a quantitative approach to speech, thought and writing representation (ST&WR) and steps towards its automatic detection. Automatic detection is necessary for studying ST&WR in a large number of texts and thus identifying developments in form and usage over time and in different types of texts. The contribution summarizes results of a pilot study: First, it describes the manual annotation of a corpus of short narrative texts in relation to linguistic descriptions of ST&WR. Then, two different techniques of automatic detection – a rule-based and a machine learning approach – are described and compared. Evaluation of the results shows success with automatic detection, especially for direct and indirect ST&WR.
