Projektvorstellung – Redewiedergabe. Eine literatur- und sprachwissenschaftliche Korpusanalyse
(2018)
Das laufende DFG-Projekt „Redewiedergabe“ stellt einen Anwendungsfall quantitativer Sprach-und Literaturwissenschaft dar und beschäftigt sich mit dem Phänomen „Redewiedergabe“ auf der Grundlage großer Datenmengen. Zu diesem Zweck wird zum einen ein Korpus manuell mit Redewiedergabeformen annotiert, zum anderen werden Verfahren zur automatischen Erkennung des Phänomens entwickelt. Ziel ist es, Forschungsfragen nach der Entwicklung von Redewiedergabe vor allem im 19. Jahrhundert zu beantworten.
In this paper, we present our work-inprogress to automatically identify free indirect representation (FI), a type of thought representation used in literary texts. With a deep learning approach using contextual string embeddings, we achieve f1 scores between 0.45 and 0.5 (sentence-based evaluation for the FI category) on two very different German corpora, a clear improvement on earlier attempts for this task. We show how consistently marked direct speech can help in this task. In our evaluation, we also consider human inter-annotator scores and thus address measures of certainty for this difficult phenomenon.
This contribution presents a quantitative approach to speech, thought and writing representation (ST&WR) and steps towards its automatic detection. Automatic detection is necessary for studying ST&WR in a large number of texts and thus identifying developments in form and usage over time and in different types of texts. The contribution summarizes results of a pilot study: First, it describes the manual annotation of a corpus of short narrative texts in relation to linguistic descriptions of ST&WR. Then, two different techniques of automatic detection – a rule-based and a machine learning approach – are described and compared. Evaluation of the results shows success with automatic detection, especially for direct and indirect ST&WR.
In this paper we outline our corpus-driven approach to detecting, describing and presenting multi- word expressions (MWEs). Our goal is to treat MWEs in a way that gives credit to their flexible nature and their role in language use. The bases of our research are a very large corpus and a Statistical method of collocation analysis. The rich empirical data is interpreted linguistically in a structured way which captures the interrelations, patterns and types of variances of MWEs. Several levels of abstraction build on each other: surface patterns, lexical realizations (LRs), MWEs and MWE patterns. Generalizations are made in a controlled way and in adherence to corpus evidence. The results are published online in a hypertext format.
We present a corpus-driven approach to the study of multi-word expressions, which constitute a significant part of. As a data basis, we use collocation profiles computed from DeReKo (Deutsches Referenzkorpus), the largest available collection of written German which has approximately two billion word tokens and is located at the Institute for the German Language (IDS). We employ a strongly usage-based approach to multi-word expressions, which we think of as conventionalised patterns in language use that manifest themselves in recurrent syntagmatic patterns of words. They are defined by their distinct function in language. To find multi-word expressions, we allow ourselves to be guided by corpus data and statistical evidence as much as possible, making interpretative steps carefully and in a monitored fashion. We develop a procedure of interpretation that leads us from the evidence of collocation profiles to a collection of recurrent word patterns and finally to multi-word expressions. When building up a collection of multi-word expressions in this fashion, it becomes clear that the expressions can be defined on different levels of generalisation and are interrelated in various ways. This will be reflected in the documentation and presentation of the findings. We are planning to add annotation in a way that allows grouping the multi-word expressions according to different features and to add links between them to reflect their relationships, thus constructing a network of multi-word expressions.
This contribution presents the newest version of our ’Wortverbindungsfelder’ (fields of multi-word expressions), an experimental lexicographic resource that focusses on aspects of MWEs that are rarely addressed in traditional descriptions: Contexts, patterns and interrelations. The MWE fields use data from a very large corpus of written German (over 6 billion word forms) and are created in a strictly corpus-based way. In addition to traditional lexicographic descriptions, they include quantitative corpus data which is structured in new ways in order to show the usage specifics. This way of looking at MWEs gives insight in the structure of language and is especially interesting for foreign language learners.
