This paper reports on recent developments within the European Reference Corpus EuReCo, an open initiative that aims at providing and using virtual and dynamically definable comparable corpora based on existing national, reference or other large corpora. Given the well-known shortcomings of other types of multilingual corpora such as parallel/translation corpora (shining-through effects, over-normalization, simplification, etc.) or web-based comparable corpora (covering only web material), EuReCo provides a unique linguistic resource offering new perspectives for fine-grained contrastive research on authentic cross-linguistic data, applications in translation studies and foreign language teaching and learning.
Das Deutsche Referenzkorpus DeReKo dient als eine empirische Grundlage für die germanistische Linguistik. In diesem Beitrag geben wir einen Überblick über Grundlagen und Neuigkeiten zu DeReKo und seine Verwendungsmöglichkeiten sowie einen Einblick in seine strategische Gesamtkonzeption, die zum Ziel hat, DeReKo trotz begrenzter Ressourcen für einerseits möglichst viele und andererseits auch für innovative und anspruchsvolle Anwendungen nutzbar zu machen. Insbesondere erläutern wir dabei Strategien zur Aufbereitung sehr großer Korpora mit notwendigerweise heuristischen Verfahren und Herausforderungen, die sich auf dem Weg zur linguistischen Erschließung solcher Korpora stellen.
Twitter data is used in a wide variety of research disciplines in Social Sciences and Humanities. Although most Twitter data is publicly available, its re-use and sharing raise many legal questions related to intellectual property and personal data protection. Moreover, the use of Twitter and its content is subject to the Terms of Service, which also regulate re-use and sharing. This extended abstract provides a brief analysis of these issues and introduces the new Academic Research product track, which enables authorized researchers to access Twitter API on a preferential basis.
Making corpora accessible and usable for linguistic research is a huge challenge in view of (too) big data, legal issues and a rapidly evolving methodology. This does not only affect the design of user-friendly graphical interfaces to corpus analysis tools, but also the availability of programming interfaces supporting access to the functionality of these tools from various analysis and development environments. RKorAPClient is a new research tool in the form of an R package that interacts with the Web API of the corpus analysis platform KorAP, which provides access to large annotated corpora, including the German reference corpus DeReKo with 45 billion tokens. In addition to optionally authenticated KorAP API access, RKorAPClient provides further processing and visualization features to simplify common corpus analysis tasks. This paper introduces the basic functionality of RKorAPClient and exemplifies various analysis tasks based on DeReKo, that are bundled within the R package and can serve as a basic framework for advanced analysis and visualization approaches.
