Dieser Beitrag setzt sich mit Gesprächskorpora als einem besonderen Typus von Korpora gesprochener Sprache auseinander. Es werden zunächst wesentliche Eigenschaften solcher Korpora herausgearbeitet und einige der wichtigsten deutschsprachigen Gesprächskorpora vorgestellt. Der zweite Teil des Beitrags setzt sich dann mit dem Forschungs- und Lehrkorpus Gesprochenes Deutsch (FOLK) auseinander. FOLK hat sich zum Ziel gesetzt, ein wissenschaftsöffentliches Korpus von Interaktionsdaten aufzubauen, das methodisch und technisch dem aktuellen Forschungsstand entspricht. Die Herausforderungen, die sich beim Aufbau von FOLK in methodischer und korpustechnologischer Hinsicht stellen, werden in abschließenden Abschnitt diskutiert.
Einleitung
(2018)
This paper is about the workflow for construction and dissemination of FOLK (Forschungs - und Lehrkorpus Gesprochenes Deutsch – Research and Teaching Corpus of Spoken German), a large corpus of authentic spoken interaction data, recorded on audio and video. Section 2 describes in detail the tools used in the individual steps of transcription, anonymization, orthographic normalization, lemmatization and POS tagging of the data, as well as some utilities used for corpus management. Section 3 deals with the DGD (Datenbank für Gesprochenes Deutsch - Database of Spoken German) as a tool for distributing completed data sets and making them available for qualitative and quantitative analysis. In section 4, some plans for further development are sketched.
Die Guidelines sind eine Erweiterung des STTS (Schiller et al. 1999) für die Annotation von Transkripten gesprochener Sprache. Dieses Tagset basiert auf der Annotation des FOLK-Korpus des IDS Mannheim (Schmidt 2014) und es wurde gegenüber dem STTS erweitert in Hinblick auf typisch gesprochensprachliche Phänomene bzw. Eigenheiten der Transkription derselben. Es entstand im Rahmen des Dissertationsprojekts „POS für(s) FOLK – Entwicklung eines automatisierten Part-of-Speech-Tagging von spontansprachlichen Daten“ (Westpfahl 2017 (i.V.)).
We present web services which implement a workflow for transcripts of spoken language following the TEI guidelines, in particular ISO 24624:2016 “Language resource management – Transcription of spoken language”. The web services are available at our website and will be available via the CLARIN infrastructure, including the Virtual Language Observatory and WebLicht.
This paper addresses long-term archival for large corpora. Three aspects specific to language resources are focused, namely (1) the removal of resources for legal reasons, (2) versioning of (unchanged) objects in constantly growing resources, especially where objects can be part of multiple releases but also part of different collections, and (3) the conversion of data to new formats for digital preservation. It is motivated why language resources may have to be changed, and why formats may need to be converted. As a solution, the use of an intermediate proxy object called a signpost is suggested. The approach will be exemplified with respect to the corpora of the Leibniz Institute for the German Language in Mannheim, namely the German Reference Corpus (DeReKo) and the Archive for Spoken German (AGD).
As a part of the ZuMult-project, we are currently modelling a backend architecture that should provide query access to corpora from the Archive of Spoken German (AGD) at the Leibniz-Institute for the German Language (IDS). We are exploring how to reuse existing search engine frameworks providing full text indices and allowing to query corpora by one of the corpus query languages (QLs) established and actively used in the corpus research community. For this purpose, we tested MTAS - an open source Lucene-based search engine for querying on text with multilevel annotations. We applied MTAS on three oral corpora stored in the TEI-based ISO standard for transcriptions of spoken language (ISO 24624:2016). These corpora differ from the corpus data that MTAS was developed for, because they include interactions with two and more speakers and are enriched, inter alia, with timeline-based annotations. In this contribution, we report our test results and address issues that arise when search frameworks originally developed for querying written corpora are being transferred into the field of spoken language.
This paper presents the prototype of a lexicographic resource for spoken German in interaction, which was conceived within the framework of the LeGeDe-project (LeGeDe=Lexik des gesprochenen Deutsch). First of all, it summarizes the theoretical and methodological approaches that were used for the initial planning of the resource. The headword candidates were selected by analyzing corpus-based data. Therefore, the data of two corpora (written and spoken German) were compared with quantitative methods. The information that was gathered on the selected headword candidates can be assigned to two different sections: meanings and functions in interaction.
Additionally, two studies on the expectations of future users towards the resource were carried out. The results of these two studies were also taken into account in the development of the prototype. Focusing on the presentation of the resource’s content, the paper shows both the different lexicographical information in selected dictionary entries, and the information offered by the provided hyperlinks and external texts. As a conclusion, it summarizes the most important innovative aspects that were specifically developed for the implementation of such a resource.
