Supplementing Cefr-graded vocabulary lists for language learners by leveraging information on dictionary views, corpus frequency, part-of-speech, and polysemy
The study explores an approach to supplementing existing CEFR -graded vocabulary lists, which are often incomplete, by imputing CEFR levels for additional vocabulary items. This is achieved by analysing word-level data such as dictionary views, corpus frequency, part-of-speech, and polysemy. Using English as a test case, the study employs a variety of machine-learning models to predict CEFR levels for words not included in the initial set. The mo…
The effectiveness of ChatGPT as a lexical tool for English, compared with a bilingual dictionary and a monolingual learner’s dictionary
Traditionally, language learners have relied on dictionaries when trying to read or write in a foreign language. However, new LLM-based chatbots may offer an alternative to traditional dictionaries as lexical tools. This study assesses the effectiveness of ChatGPT versus the monolingual Longman Dictionary of Contemporary English (LDOCE, 2024) and the bilingual Diki.pl (Diki.pl, 2024) online dictionaries in supporting English language learners in …
Cefr vocabulary level as a predictor of user interest in English Wiktionary entries
This contribution explores the relationship between the English CEFR (Common European Framework of Reference for Languages) vocabulary levels and user interest in English Wiktionary entries. User interest was operationalized through the number of views of these entries in Wikimedia server logs covering a period of four years (2019–2022). Our findings reveal a significant relationship between CEFR levels and user interest: entries classified at lo…
What Lexical Factors Drive Look-Ups in the English Wiktionary
This study aims to establish what lexical factors make it more likely for dictionary users to consult specific articles in a dictionary using the English Wiktionary log files, which include records of user visits over the course of 6 years. Recent findings suggest that lexical frequency is a significant factor predicting look-up behavior, with the more frequent words being more likely to be consulted. Three further lexical factors are brought int…
A Learners’ Dictionary Versus ChatGPT in Receptive and Productive Lexical Tasks
This study assesses the effectiveness of ChatGPT versus the Longman Dictionary of Contemporary English (LDOCE) in supporting English language learners in lexically challenging receptive and productive lexical tasks. With a sample of 223 university students at B2 to C1 proficiency levels, this research investigates whether a leading AI-driven chatbot or a high-quality learners’ dictionary better assists learners in accurately understanding and pro…
Tracking the acceptance of neologisms in German
Neologisms, i.e., new words or meanings, are finding their way into everyday language use all the time. In the process, already existing elements of a language are recombined or linguistic material from other languages is borrowed. But are borrowed neologisms accepted similarly well by the speech community as neologisms that were formed from “native” material? We investigate this question based on neologisms in German. Building on the correspondi…
Wochenaktuelle lexikalische Spuren der Corona-Krise in deutschen Online-Nachrichtenmeldungen
Die Corona-Pandemie betrifft fast alle Facetten des öffentlichen Lebens und hat nicht nur erhebliche Auswirkungen auf den persönlichen Umgang miteinander, sondern beherrscht auch die Berichterstattung im großen Stil. In unserem Beitrag wollen wir zeigen, welche lexikalischen Spuren oder Trends der Coronakrise wir in der deutschen Online-Nachrichtenberichterstattung beobachten können, obwohl wir uns noch mitten in der Pandemie zu befinden scheinen…
Mit der Fähre nach Island, weil Flugangst. Textsortenspezifische Angemessenheit von weil mit Verbletztstellung, weil mit Verbzweitstellung und in elliptischen Konstruktionen empirisch untersucht
Im vorliegenden Beitrag gehen wir von der Prämisse aus, dass die Angemessenheit sprachlicher Formen nicht pauschal, sondern anhand des jeweiligen Kontexts zu beurteilen ist. Anhand einer Online-Fragebogenstudie mit durch weil eingeleiteten Nebensätzen untersuchen wir die Hypothese, dass Varianten, die nicht dem Schriftstandard entsprechen, in Kommunikationsformen, die sich weniger an standard- und schriftsprachlichen Normen orientieren, als (mind…
Recherchepraxis bei der Verbesserung von Interferenzfehlern aus dem Italienischen, Portugiesischen und Spanischen
In the past two decades, more and more dictionary usage studies have been published, but most of them deal with the question what users appreciate about dictionaries, which dictionaries they use and which information they need in specific situations. These studies presuppose that users indeed consult lexicographic resources. However, language teachers and lecturers of linguistics often have the impression that students use too few high-quality di…
The Relationship Between Dictionary Look-up Frequency and Corpus Frequency Revisited
In an earlier publication it was claimed that there is no useful relationship between Swahili-English dictionary look-up frequencies and the occurrence frequencies for the same wordforms in Swahili-English corpora, at least not beyond the top few thousand wordforms. This result was challenged using data for German by a different team of researchers using an improved methodology. In the present article the original Swahili-English data is revisite…
Considerations on the Acceptance of German neologisms from the 1990s
Are borrowed neologisms accepted more slowly into the German language than German words resulting from the application of wrd formation rules? This study addresses this question by focusing on two possible indicators for the acceptance of neologisms: a) frequency development of 239 German neologisms from the 1990s (loanwords as well as new words resulting from the application of word formation rules) in the German reference corpus DeReKo and b) f…

Die IDS-Goethe-Studie in den Integrationskursen
Der Beitrag widmet sich den Geflüchteten als Teil der deutschlernenden Teilnehmer/innen in den staatlich verordneten Integrationskursen (IKs). Unsere Erhebung unter 305 Geflüchteten aus Syrien und anderen Ländern legt ihren Schwerpunkt auf die sprachlichen Hintergründe. Dabei werden soziodemografische Daten mit Angaben zum Spracherwerb in Beziehung gesetzt und als kollektive Sprachbiografien dargestellt. Des Weiteren beschreiben wir sieben Teilne…
The Image of the Monolingual Dictionary Across Europe. Results of the European Survey of Dictionary use and Culture
The article presents the results of a survey on dictionary use in Europe, focusing on general monolingual dictionaries. The survey is the broadest survey of dictionary use to date, covering close to 10,000 dictionary users (and non-users) in nearly thirty countries. Our survey covers varied user groups, going beyond the students and translators who have tended to dominate such studies thus far. The survey was delivered via an online survey platfo…
The Effectiveness of Lexicographic Tools for Optimising Written L1-Texts
We present an empirical study addressing the question whether, and to which extent, lexicographic writing aids improve text revision results. German university students were asked to optimise two German texts using (1) no aids at all, (2) highlighted problems, or (3) highlighted problems accompanied by lexicographic resources that could be used to solve the specific problems. We found that participants from the third group corrected the largest n…

In this contribution, we present a novel approach for the analysis of cross-reference structures in digital dictionaries on the basis of the complete dictionary database. Using paradigmatic items in the German Wiktionary as an example, we show how analyses based on graph theory can be fruitfully applied in this context, e. g. to gain an overview of paradigmatic references as a whole or to detect closely connected groups of headwords. Furthermore,…
