We present a simple tool for extracting text and markup information from printouts of (not only) scientific documents. While the heavy-lifting OCR is done by off-the-shelf tesseract, our focus is on detection, extraction, and basic categorization of color-highlighted text sections, as well as on providing a framework for downstream processing of extraction results. The tool can be useful for document analysis tasks that must, or benefit from being able to, use printed paper.
Seit Mitte der 1990er Jahre wird am Institut für deutsche Sprache (IDS) in Mannheim erforscht, wie der hochkomplexe Gegenstandsbereich „Grammatik“ unter Ausnutzung hypertextueller Navigationsstrukturen wissenschaftlich fundiert und anschaulich vermittelt werden kann. Eine zentrale Bedeutung kommt folglich einer konsistenten, theorieübergreifenden Vernetzung sämtlicher Textinhalte zu. Um eine automatisierbare Bezugnahme zwischen mit unterschiedlichem terminologischem Vokabular formulierten, aber das gleiche sprachliche Phänomen beschreibenden Inhalten zu befördern, bildet eine onomasiologisch konzipierte Terminologiedatenbank das Rückgrat des Online-Systems. Der Beitrag beschreibt Konzeption und Aufbau der skizzierten linguistischen Fachterminologie.
The CLARIN Concept Registry (CCR) is the common semantic ground for most CMDI-based profiles to describe language-related resources in the CLARIN universe. While the CCR supports semantic interoperability within this universe, it does not extend beyond it. The flexibility of CMDI, however, allows users to use other term or concept registries when defining their metadata components. In this paper, we describe our use of schema.org, a light ontology used by many parties across disciplines.
Das Ziel des Beitrags ist es, die Merkmale von Kommunikationsstörungen in Sport-Interviews aus Sicht der Interviewten festzustellen und zu analysieren. Die empirische Forschungsbasis besteht aus ukrainisch- und deutschsprachigen Videointerviews aus den Jahren 2010 bis 2019, die entweder im Fernsehen gesendet oder für YouTube produziert wurden. Die Ergebnisse der Studie ermöglichten es, die charakteristischen Merkmale von Abweichungen als Kommunikationsstörungen in Sport-Interviews auf drei Ebenen der kommunikativen Gattung zu identifizieren: auf der außenstrukturellen, binnenstrukturellen und situativen Ebene. Sowohl gemeinsame Merkmale von Kommunikationsstörungen als auch Unterschiede in den ukrainisch- und deutschsprachigen Sport-Interviews wurden bestimmt. Die Ergebnisse der Studie zeigen, dass die Arten von Kommunikationsstörungen in Sport-Interviews im Ukrainischen und Deutschen universell sind, sie spiegeln jedoch die nationalen und kulturellen Besonderheiten angesichts der Merkmale beider Sprachen und jeder Sprachkultur wider.
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.
In this paper, we deal with register-driven variation from a probabilistic perspective, as proposed in Schäfer, Bildhauer, Pankratz, Müller (2022). We compare two approaches to analyse this variation within HPSG. On the one hand, we consider a multiple-grammar approach and combine it with the architecture proposed in the CoreGram project Müller (2015) - discussing its advantages and disadvantages. On the other hand, we take into account a single-grammar approach and argue that it appears to be superior due to its computational efficiency and cognitive plausibility.
Das Lehnwortportal Deutsch (LWPD) ist ein Online-Informationssystem zu Entlehnungen von Wörtern aus dem Deutschen in andere Sprachen. Es beruht auf einer wachsenden Zahl von lexikographischen Ressourcen zu verschiedenen Sprachen und bietet eine einfache ressourcenübergreifende Suchfunktion an. Das Poster präsentiert eine derzeit in Entwicklung befindliche onomasiologische Suchfunktion für das LWPD.
The Leibniz-Institute for the German Language (IDS) was established in Mannheim in 1964. Since then, it has been at the forefront of innovation in German linguistics as a hub for digital language data. This chapter presents various lessons learnt from over five decades of work by the IDS, ranging from the importance of sustainability, through its strong technical base and FAIR principles, to the IDS’ role in national and international cooperation projects and its expertise on legal and ethical issues related to language resources and language technology.
Um eine bessere Erreichbarkeit und Zugänglichkeit zu bestehenden sowie neuen Angeboten von Lehr- und Schulungsmaterialien im Bereich der Digital Humanities zu ermöglichen, sollten diese in einem zentralen Verzeichnis zur Verfügung gestellt werden. Im Rahmen des CLARIAH-DE Projekts wurde – zunächst für die Umsetzung eines Projektmeilensteins – eine Lösung gesucht, die eine übergreifende Suche in frei zugänglichen und nachnutzbaren Lehr- und Schulungsmaterialien zu Forschungsmethoden, Verfahren sowie Werkzeugen im Bereich der Digital Humanities in unterschiedlichen Plattformen und Repositorien bietet.
We address the task of distinguishing implicitly abusive sentences on identity groups (“Muslims contaminate our planet”) from other group-related negative polar sentences (“Muslims despise terrorism”). Implicitly abusive language are utterances not conveyed by abusive words (e.g. “bimbo” or “scum”). So far, the detection of such utterances could not be properly addressed since existing datasets displaying a high degree of implicit abuse are fairly biased. Following the recently-proposed strategy to solve implicit abuse by separately addressing its different subtypes, we present a new focused and less biased dataset that consists of the subtype of atomic negative sentences about identity groups. For that task, we model components that each address one facet of such implicit abuse, i.e. depiction as perpetrators, aspectual classification and non-conformist views. The approach generalizes across different identity groups and languages.
This paper presents the Lehnwortportal Deutsch, a new, freely accessible publication platform for resources on German lexical borrowings in other languages, to be launched in the second half of 2022. The system will host digital-native sources as well as existing, digitized paper dictionaries on loanwords, initially for some 15 recipient languages. All resources remain accessible as individual standalone dictionaries; in addition, data on words (etyma, loanwords etc.) together with their senses and relations to each other is represented as a cross-resource network in a graph database, with careful distinction between information present in the original sources and the curated portal network data resulting from matching and merging information on, e. g., lexical units appearing in multiple dictionaries. Special tooling is available for manually creating graphs from dictionary entries during digitization and for editing and augmenting the graph database. The user interface allows users to browse individual dictionaries, navigate through the underlying graph and ‘click together’ complex queries on borrowing constellations in the graph in an intuitive way. The web application will be available as open source.
Germany’s diverse history in the 20th century raises the question of how social upheavals were constituted in and through political discourse. By analysing basic concepts, the research network “The 20th century in basic concepts” (based at the Leibniz institutes IDS, ZfL, ZZF) aims to identify continuities and discontinuities in political and social discourse. In this way, historical sediments of the present are to be uncovered and those challenges identified that emerged in the course of the 20th century and continue to shape political discourse until the present.
This paper describes the TEI-based ISO standard 24624:2016 ‘Transcription of spoken language’ and other formats used within CLARIN for spoken language resources. It assesses the current state of support for the standard and the interoperability between these formats and with rele- vant tools and services. The main idea behind the paper is that a digital infrastructure providing language resources and services to researchers should also allow the combined use of resources and/or services from different contexts. This requires syntactic and semantic interoperability. We propose a solution based on the ISO/TEI format and describe the necessary steps for this format to work as an exchange format with basic semantic interoperability for spoken language resources across the CLARIN infrastructure and beyond.
This paper presents an algorithm and an implementation for efficient tokenization of texts of space-delimited languages based on a deterministic finite state automaton. Two representations of the underlying data structure are presented and a model implementation for German is compared with state-of-the-art approaches. The presented solution is faster than other tools while maintaining comparable quality.
We present the use of count-based and predictive language models for exploring language use in the German Reference Corpus DeReKo. For collocation analysis along the syntagmatic axis we employ traditional association measures based on co-occurrence counts as well as predictive association measures derived from the output weights of skipgram word embeddings. For inspecting the semantic neighbourhood of words along the paradigmatic axis we visualize the high dimensional word embeddings in two dimensions using t-stochastic neighbourhood embeddings. Together, these visualizations provide a complementary, explorative approach to analysing very large corpora in addition to corpus querying. Moreover, we discuss count-based and predictive models w.r.t. scalability and maintainability in very large corpora.
The debate on the use of personal data in language resources usually focuses — and rightfully so — on anonymisation. However, this very same debate usually ends quickly with the conclusion that proper anonymisation would necessarily cause loss of linguistically valuable information. This paper discusses an alternative approach — pseudonymisation. While pseudonymisation does not solve all the problems (inasmuch as pseudonymised data are still to be regarded as personal data and therefore their processing should still comply with the GDPR principles), it does provide a significant relief, especially — but not only — for those who process personal data for research purposes. This paper describes pseudonymisation as a measure to safeguard rights and interests of data subjects under the GDPR (with a special focus on the right to be informed). It also provides a concrete example of pseudonymisation carried out within a research project at the Institute of Information Technology and Communications of the Otto von Guericke University Magdeburg.
In diesem Beitrag widmen wir uns der Frage, welche Schritte unternommen werden müssen, um Skripte, die bei der Aufbereitung und/oder Auswertung von Forschungsdaten Anwendung finden, so FAIR wie möglich zu gestalten. Dabei nehmen wir sowohl Reproduzierbarkeit, also den Weg von den (Roh)daten zu den Ergebnissen einer Studie, als auch Wiederverwertbarkeit, also die Möglichkeit, die Methoden einer Studie mittels des Skripts auf andere Daten anzuwenden, in den Fokus und beleuchten dabei die folgenden Aspekte: Arbeitsumgebung, Datenvalidierung, Modularisierung, Dokumentation und Lizenz.
