A comparison between morphological complexity measures: typological data vs. language corpora
(2016)
Language complexity is an intriguing phenomenon argued to play an important role in both language learning and processing. The need to compare languages with regard to their complexity resulted in a multitude of approaches and methods, ranging from accounts targeting specific structural features to global quantification of variation more generally. In this paper, we investigate the degree to which morphological complexity measures are mutually correlated in a sample of more than 500 languages of 101 language families. We use human expert judgements from the World Atlas of Language Structures (WALS), and compare them to four quantitative measures automatically calculated from language corpora. These consist of three previously defined corpus-derived measures, which are all monolingual, and one new measure based on automatic word-alignment across pairs of languages. We find strong correlations between all the measures, illustrating that both expert judgements and automated approaches converge to similar complexity ratings, and can be used interchangeably.
In this paper, an exploratory data-driven method is presented that extracts word-types from diachronic corpora that have undergone the most pronounced change in frequency of occurrence in a given period of time. Combined with statistical methods from time series analysis, the method is able to find meaningful patterns and relationships in diachronic corpora, an idea that is still uncommon in linguistics. This indicates that the approach can facilitate an improved understanding of diachronic processes.
In this paper, a method for measuring synchronic corpus (dis-)similarity put forward by Kilgarriff (2001) is adapted and extended to identify trends and correlated changes in diachronic text data, using the Corpus of Historical American English (Davies 2010a) and the Google Ngram Corpora (Michel et al. 2010a). This paper shows that this fully data-driven method, which extracts word types that have undergone the most pronounced change in frequency in a given period of time, is computationally very cheap and that it allows interpretations of diachronic trends that are both intuitively plausible and motivated from the perspective of information theory. Furthermore, it demonstrates that the method is able to identify correlated linguistic changes and diachronic shifts that can be linked to historical events. Finally, it can help to improve diachronic POS tagging and complement existing NLP approaches. This indicates that the approach can facilitate an improved understanding of diachronic processes in language change.
One of the fundamental questions about human language is whether all languages are equally complex. Here, we approach this question from an information-theoretic perspective. We present a large scale quantitative cross-linguistic analysis of written language by training a language model on more than 6500 different documents as represented in 41 multilingual text collections consisting of ~ 3.5 billion words or ~ 9.0 billion characters and covering 2069 different languages that are spoken as a native language by more than 90% of the world population. We statistically infer the entropy of each language model as an index of what we call average prediction complexity. We compare complexity rankings across corpora and show that a language that tends to be more complex than another language in one corpus also tends to be more complex in another corpus. In addition, we show that speaker population size predicts entropy. We argue that both results constitute evidence against the equi-complexity hypothesis from an information-theoretic perspective.
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.
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.

Frimer et al. (2015) claim that there is a linear relationship between the level of prosocial language and the level of public disapproval of US Congress. A re-analysis demonstrates that this relationship is the result of a misspecified model that does not account for first-order autocorrelated disturbances. A Stata script to reproduce all presented results is available as an appendix.
In this paper, we present the concept and the results of two studies addressing (potential) users of monolingual German online dictionaries, such as www.elexiko.de. Drawing on the example of elexiko, the aim of those studies was to collect empirical data on possible extensions of the content of monolingual online dictionaries, e.g. the search function, to evaluate how users comprehend the terminology of the user interface, to find out which types of information are expected to be included in each specific lexicographic module and to investigate general questions regarding the function and reception of examples illustrating the use of a word. The design and distribution of the surveys is comparable to the studies described in the chapters 5-8 of this volume. We also explain, how the data obtained in our studies were used for further improvement of the elexiko-dictionary.
Im vorliegenden Beitrag werden Ergebnisse aus zwei Benutzungsstudien präsentiert, die zum Wörterbuch elexiko im Januar bzw. März 2011 realisiert wurden. Wörterbuchbenutzungsforschung für ein neu konzipiertes, noch im Aufbau befindliches, umfangreiches Onlinewörterbuch zur deutschen Gegenwartssprache wie elexiko ist bislang nur in geringem Umfang durchgeführt worden.Dabei ist der Bedarf an Klärung der Benutzerbedürfnisse und -meinungen insgesamt groß. Solch eine Klärung kann einerseits als Bestätigung von Entscheidungen, die für Inhalt und Präsentation des Wörterbuchs getroffen wurden, dienen. Sie dient andererseits aber auch als Anregung für deren Verbesserung auf der Grundlage nicht vermeintlicher, sondern tatsächlicher Bedürfnisse und Meinungen zur Wörterbuchbenutzung.
It was recently suggested in a study published in Nature Human Behaviour that the historical loosening of American culture was associated with a trade-off between higher creativity and lower order. To this end, Jackson et al. generate a linguistic index of cultural tightness based on the Google Books Ngram corpus and use this index to show that American norms loosened between 1800 and 2000. While we remain agnostic toward a potential loosening of American culture and a statistical association with creativity/order, we show here that the methods used by Jackson et al. are neither suitable for testing the validity of the index nor for establishing possible relationships with creativity/order.
In a previous study, Aceves and Evans present a large-scale quantitative information-theoretic analysis of parallel corpus data in ~1,000 languages to show that there are apparently strong associations between the way languages encode information into words and patterns of communication, e.g. the configuration of semantic information. During the peer review process, one reviewer raised the question of the extent to which the presented results depend on different corpus sizes (see the Peer Review File). This is a very important question given that most, if not all, of the quantities associated with word frequency distributions vary systematically with corpus size. While Aceves and Evans claim that corpus size does not affect the results presented, I challenge this view by presenting reanalyses of the data that clearly suggest that it does.

Die Corona-Krise hat Einfluss auf die Sprache in deutschsprachigen Online-Medien. Wir haben die Hypothese, dass sich die Vielfältigkeit des verwendeten Vokabulars einschränkt. Wir glauben zudem, dass sich die Diversität des Vokabulars nach "überstandener" Krise wieder auf ein "Prä-Pandemie-Niveau" einpendeln wird. Diese zweite Hypothese lässt sich erst im Laufe der Zeit überprüfen.
cOWIDplus Analyse ist eine kontinuierlich aktualisierte Ressource zu der Frage, ob und wie stark sich der Wortschatz ausgewählter deutscher Online-Pressemeldungen während der Corona-Pandemie systematisch einschränkt und ob bzw. wann sich das Vokabular nach der Krise wieder ausweitet.

We start by trying to answer a question that has already been asked by de Schryver et al. (2006): Do dictionary users (frequently) look up words that are frequent in a corpus. Contrary to their results, our results that are based on the analysis of log files from two different online dictionaries indicate that users indeed look up frequent words frequently. When combining frequency information from the Mannheim German Reference Corpus and information about the number of visits in the Digital Dictionary of the German Language as well as the German language edition of Wiktionary, a clear connection between corpus and look-up frequencies can be observed. In a follow-up study, we show that another important factor for the look-up frequency of a word is its temporal social relevance. To make this effect visible, we propose a de-trending method where we control both frequency effects and overall look-up trends.
In this paper, the authors use the 2012 log files of two German online dictionaries (Digital Dictionary of the German Language and the German Version of Wiktionary) and the 100,000 most frequent words in the Mannheim German Reference Corpus from 2009 to answer the question of whether dictionary users really do look up frequent words, first asked by de Schryver et al. (2006). By using an approach to the comparison of log files and corpus data which is completely different from that of the aforementioned authors, we provide empirical evidence that indicates - contrary to the results of de Schryver et al. and Verlinde/Binon (2010) - that the corpus frequency of a word can indeed be an important factor in determining what online dictionary users look up. Finally, we incorporate word class Information readily available in Wiktionary into our analysis to improve our results considerably.
This chapter summarizes the typical steps of an empirical investigation. Every step is illustrated using examples from our research project into online dictionary use or other relevant studies. This chapter does not claim to contain anything new, but presents a brief guideline for lexicographical researchers who are interested in conducting their own empirical research.
The main aim of the study presented in this chapter was to try out eyetracking as form to collect data about dictionary use as it is – for research into dictionary use – a new and not widely used technology. As the topic of research, we decided to evaluate the new web design of the IDS dictionary portal OWID. In the mid of 2011 where the study was conducted, the relaunch of the web design was internally finished but externally not released yet. In this regard, it was a good time to see whether users get along well with the new design decisions. 38 persons participated in our study, all of them students aged 20-30 years. Besides the results the chapter also includes critical comments on methodological aspects of our study.
The first international study (N=684) we conducted within our research project on online dictionary use included very general questions on that topic. In this chapter, we present the corresponding results on questions like the use of both printed and online dictionaries as well as on the types of dictionaries used, devices used to access online dictionaries and some information regarding the willingness to pay for premium content. The data collected by us, show that our respondents both use printed and online dictionaries and, according to their self-report, many different kinds of dictionaries. In this context, our results revealed some clear cultural differences: in German-speaking areas spelling dictionaries are more common than in other linguistic areas, where thesauruses are widespread. Only a minority of our respondents is willing to pay for premium content, but most of the respondents are prepared to accept advertising. Our results also demonstrate that our respondents mainly tend to use dictionaries on big-screen devices, e.g. desktop computers or laptops.
A central goal of linguistics is to understand the diverse ways in which human language can be organized (Gibson et al. 2019; Lupyan/Dale 2016). In our contribution, we present results of a large scale cross-linguistic analysis of the statistical structure of written language (Koplenig/Wolfer/Meyer 2023) we approach this question from an information-theoretic perspective. To this end, we conduct a large scale quantitative cross-linguistic analysis of written language by training a language model on more than 6,500 different documents as represented in 41 multilingual text collections, so-called corpora, consisting of ~3.5 billion words or ~9.0 billion characters and covering 2,069 different languages that are spoken as a native language by more than 90% of the world population. We statistically infer the entropy of each language model as an index of un. To this end, we have trained a language model on more than 6,500 different documents as represented in 41 parallel/multilingual corpora consisting of ~3.5 billion words or ~9.0 billion characters and covering 2,069 different languages that are spoken as a native language by more than 90% of the world population or ~46% of all languages that have a standardized written representation. Figure 1 shows that our database covers a large variety of different text types, e.g. religious texts, legalese texts, subtitles for various movies and talks, newspaper texts, web crawls, Wikipedia articles, or translated example sentences from a free collaborative online database. Furthermore, we use word frequency information from the Crúbadán project that aims at creating text corpora for a large number of (especially under-resourced) languages (Scannell 2007). We statistically infer the entropy rate of each language model as an information-theoretic index of (un)predictability/complexity (Schürmann/Grassberger 1996; Takahira/Tanaka-Ishii/Dębowski 2016). Equipped with this database and information-theoretic estimation framework, we first evaluate the so-called ‘equi-complexity hypothesis’, the idea that all languages are equally complex (Sampson 2009). We compare complexity rankings across corpora and show that a language that tends to be more complex than another language in one corpus also tends to be more complex in another corpus. This constitutes evidence against the equi-complexity hypothesis from an information-theoretic perspective. We then present, discuss and evaluate evidence for a complexity-efficiency trade-off that unexpectedly emerged when we analysed our database: high-entropy languages tend to need fewer symbols to encode messages and vice versa. Given that, from an information theoretic point of view, the message length quantifies efficiency – the shorter the encoded message the higher the efficiency (Gibson et al. 2019) – this indicates that human languages trade off efficiency against complexity. More explicitly, a higher average amount of choice/uncertainty per produced/received symbol is compensated by a shorter average message length. Finally, we present results that could point toward the idea that the absolute amount of information in parallel texts is invariant across different languages.
We introduce DeReKoGram, a novel frequency dataset containing lemma and part-of-speech (POS) information for 1-, 2-, and 3-grams from the German Reference Corpus. The dataset contains information based on a corpus of 43.2 billion tokens and is divided into 16 parts based on 16 corpus folds. We describe how the dataset was created and structured. By evaluating the distribution over the 16 folds, we show that it is possible to work with a subset of the folds in many use cases (e.g., to save computational resources). In a case study, we investigate the growth of vocabulary (as well as the number of hapax legomena) as an increasing number of folds are included in the analysis. We cross-combine this with the various cleaning stages of the dataset. We also give some guidance in the form of Python, R, and Stata markdown scripts on how to work with the resource.
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.
Computational language models (LMs), most notably exemplified by the widespread success of OpenAI's ChatGPT chatbot, show impressive performance on a wide range of linguistic tasks, thus providing cognitive science and linguistics with a computational working model to empirically study different aspects of human language. Here, we use LMs to test the hypothesis that languages with more speakers tend to be easier to learn. In two experiments, we train several LMs—ranging from very simple n-gram models to state-of-the-art deep neural networks—on written cross-linguistic corpus data covering 1293 different languages and statistically estimate learning difficulty. Using a variety of quantitative methods and machine learning techniques to account for phylogenetic relatedness and geographical proximity of languages, we show that there is robust evidence for a relationship between learning difficulty and speaker population size. However, contrary to expectations derived from previous research, our results suggest that languages with more speakers tend to be harder to learn.
Less than one percent of words would be affected by gender-inclusive language in German press texts
(2024)
Research on gender and language is tightly knitted to social debates on gender equality and non-discriminatory language use. Psycholinguistic scholars have made significant contributions in this field. However, corpus-based studies that investigate these matters within the context of language use are still rare. In our study, we address the question of how much textual material would actually have to be changed if non-gender-inclusive texts were rewritten to be gender-inclusive. This quantitative measure is an important empirical insight, as a recurring argument against the use of gender-inclusive German is that it supposedly makes written texts too long and complicated. It is also argued that gender-inclusive language has negative effects on language learners. However, such effects are only likely if gender-inclusive texts are very different from those that are not gender-inclusive. In our corpus-linguistic study, we manually annotated German press texts to identify the parts that would have to be changed. Our results show that, on average, less than 1% of all tokens would be affected by gender-inclusive language. This small proportion calls into question whether gender-inclusive German presents a substantial barrier to understanding and learning the language, particularly when we take into account the potential complexities of interpreting masculine generics.
Thema des Aufsatzes ist die Komplementsatzdistribution im Deutschen. Überprüft wird die These, dass die lexikalisch-semantischen Eigenschaften der einbettenden Verben, dabei v.a. ihre Kontrolleigenschaften sowie ihre temporale und modale Spezifikation, dafür verantwortlich sind, ob bevorzugt ein dass-Satz oder ein zu-Infinitiv selegiert wird. Eine korpuslinguistische Überprüfung dieser These zeigt, dass die genannten drei Kriterien in unterschiedlicher Weise von Bedeutung für die Komplementselektion sind. Als bedeutendster Faktor erweist sich das Kontrollkriterium. Ein weiteres wichtiges Ergebnis der Untersuchung ist, dass die Komplementselektion dem Prinzip der argumentstrukturellen Trägheit entspricht: Verben neigen dazu, als Essenz memorisierter Gebrauchsspuren eine graduelle Präferenz für ein bestimmtes Komplementationsmuster zu entwickeln.
Metalinguistic awareness of standard vs standard usage. The case of determiners in spoken German
(2015)
Der folgende Leitfaden bietet eine grundlegende Übersicht darüber, welche Schritte bei der Konzeption und Durchführung einer empirischen Untersuchung in der germanistischen Linguistik zu beachten sind. Wir werden den grundlegenden Ablauf und die zugrunde liegenden Konzepte allgemein bzw. modellhaft beschreiben und sie anhand von einfachen Beispielen illustrieren. Eine stärkere Ausgestaltung anhand von Beispielen zu verschiedenen linguistischen Forschungsfragen und -feldern und damit auch mehr Illustrationen, wie die einzelnen Schritte für bestimmte Forschungsfragen umzusetzen sind, finden Sie in den Fallstudien im —> Teil III dieses Bandes. Detailliertere Ausführungen zu den zentralen Konzepten des empirischen Arbeitens in der Linguistik finden Sie in —> Teil VI dieses Bandes. Weiterführende Literatur findet sich am Ende des Beitrags.
This paper explores speakers’ notions of the situational appropriacy of linguistic variants. We conducted a web-based survey in which we collected ratings of the appropriacy of variants of linguistic variables in spoken German. A range of quantitative methods (cluster analysis, factor analysis and various forms of visualization techniques) is applied in order to analyze metalinguistic awareness and the differences in the evaluation of written vs. spoken stimuli. First, our data show that speakers’ ratings of the appropriacy of linguistic variants vary reliably with two rough clusters representing formal and informal speech situations and genres. The findings confirm that speakers adhere to a notion of spoken standard German which takes genre and register-related variation into account. Secondly, our analysis reveals a written language bias: metalinguistic awareness is strongly influenced by the physical mode of the presentation of linguistic items (spoken vs. written).
In a previous study published in Nature Human Behaviour, Varnum and Grossmann claim that reductions in gender inequality are linked to reductions in pathogen prevalence in the United States between 1951 and 2013. Since the statistical methods used by Varnum and Grossmann are known to induce (seemingly) significant correlations between unrelated time series, so-called spurious or non-sense correlations, we test here whether the statistical association between gender inequality and pathogens prevalence in its current form also is the result of mis-specified models that do not correctly account for the temporal structure of the data. Our analysis clearly suggests that this is the case. We then discuss and apply several standard approaches of modelling time-series processes in the data and show that there is, at least as of now, no support for a statistical association between gender inequality and pathogen prevalence.
We present studies using the 2013 log files from the German version of Wiktionary. We investigate several lexicographically relevant variables and their effect on look-up frequency: Corpus frequency of the headword seems to have a strong effect on the number of visits to a Wiktionary entry. We then consider the question of whether polysemic words are looked up more often than monosemic ones. Here, we also have to take into account that polysemic words are more frequent in most languages. Finally, we present a technique to investigate the time-course of look-up behaviour for specific entries. We exemplify the method by investigating influences of (temporary) social relevance of specific headwords.
This chapter presents empirical findings on the question which criteria are making a good online dictionary using data on expectations and demands collected in the first study (N=684), completed with additional results from the second study (N=390) which examined more closely whether the respondents had differentiated views on individual aspects of the criteria rated in the first study. Our results show that the classical criteria of reference books (e.g. reliability, clarity) were rated highest by our participants, whereas the unique characteristics of online dictionaries (e.g. multimedia, adaptability) were rated and ranked as (partly) unimportant. To verify whether or not the poor rating of these innovative features was a result of the fact that the subjects are not used to online dictionaries incorporating those features, we integrated an experiment into the second study. Our results revealed a learning effect: Participants in the learning-effect condition, i. e. respondents who were first presented with examples of possible innovative features of online dictionaries,judged adaptability and multimedia to be more useful than participants who did not have this information. Thus, our data point to the conclusion that developing innovative features is worthwhile but that it is necessary to be aware of the fact that users can only be convinced of its benefits gradually.
Online dictionary use
(2012)
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.
Information theory can be used to assess how efficiently a message is transmitted on the basis of different symbolic systems. In this paper, I estimate the information-theoretic efficiency of written language for parallel text data in more than 1000 different languages, both on the level of characters and on the level of words as information encoding units. The main results show that (i) the median efficiency is ∼29% on the character level and ∼45% on the word level, (ii) efficiency on both levels is strongly correlated with each other and (iii) efficiency tends to be higher for languages with more speakers.
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.
Questions of design
(2014)
All lexicographers working on online dictionary projects that do not wish to use an established form of design for their online dictionary, or simply have new kinds of lexicographic data to present, face the problem of what kind of arrangement is best suited for the intended users of the dictionary. In this chapter, we present data about questions relating to the design of online dictionaries. This will provide projects that use these or similar ways of presenting their lexicographic data with valuable information about how potential dictionary users assess and evaluate them. In addition, the answers to corresponding open-ended questions show, detached from concrete design models, which criteria potential users value in a good online representation. Clarity and an uncluttered look seem to dominate in many answers, as well as the possibility of customization, if the latter is not connected with a too complex usability model.
This article presents empirical findings about what criteria make for a good online dictionary, using data on expectations and demands collected in an online questionnaire (N~684), complemented by additional results from a second questionnaire (N-390) which looked more closely at whether respondents had differentiated views on individual aspects of the criteria rated in the first study. Our results show that the classical criteria of reference books (such as reliability and clarity) were rated highest by our participants, whereas the unique characteristics of online dictionaries (such as multimedia and adaptability) were rated and ranked as (partly) unimportant. To verify whether or not the poor ratings of these innovative features were a result of the fact that our subjects are unfamiliar with online dictionaries incorporating such features, we incorporated an experiment into the second study. Our results revealed a learning effect: participants in the learning-effect condition, i.e. respondents who were first presented with examples of possible innovative features of online dictionaries, judged adaptability and multimedia to be more useful than participants who were not given that information. Thus, our data point to the conclusion that developing innovative features is worthwhile but that it should be borne in mind that users can only be persuaded of their benefits gradually. In addition, we present data about questions relating to the design of online dictionaries.
In a recent paper published in the Journal of Language Evolution, Kauhanen, Einhaus & Walkden (KEW) challenge the results presented in one of my papers (Koplenig, Royal Society Open Science, 6, 181274 (2019)), in which I tried to show through a series of statistical analyses that large numbers of L2 (second language) speakers do not seem to affect the (grammatical or statistical) complexity of a language. To this end, I focus on the way in which the Ethnologue assesses language status: a language is characterised as vehicular if, in addition to being used by L1 (first language) speakers, it should also have a significant number of L2 users. KEW criticise both the use of vehicularity as a (binary) indicator of whether a language has a significant number of L2 users and the idea of imputing a zero proportion of L2 speakers to non-vehicular languages whenever a direct estimate of that proportion is unavailable. While I recognise the importance of post-publication commentary on published research, I show in this rejoinder that both points of criticism are explicitly mentioned and analysed in my paper. In addition, I also comment on other points raised by KEW and demonstrate that both alternative analyses offered by KEW do not stand up to closer scrutiny.
Studying Lexical Dynamics and Language Change via Generalized Entropies: The Problem of Sample Size
(2020)
Recently, it was demonstrated that generalized entropies of order α offer novel and important opportunities to quantify the similarity of symbol sequences where α is a free parameter. Varying this parameter makes it possible to magnify differences between different texts at specific scales of the corresponding word frequency spectrum. For the analysis of the statistical properties of natural languages, this is especially interesting, because textual data are characterized by Zipf’s law, i.e., there are very few word types that occur very often (e.g., function words expressing grammatical relationships) and many word types with a very low frequency (e.g., content words carrying most of the meaning of a sentence). Here, this approach is systematically and empirically studied by analyzing the lexical dynamics of the German weekly news magazine Der Spiegel (consisting of approximately 365,000 articles and 237,000,000 words that were published between 1947 and 2017). We show that, analogous to most other measures in quantitative linguistics, similarity measures based on generalized entropies depend heavily on the sample size (i.e., text length). We argue that this makes it difficult to quantify lexical dynamics and language change and show that standard sampling approaches do not solve this problem. We discuss the consequences of the results for the statistical analysis of languages.
