Towards Identifying Alternative-Lexicalization Signals of Discourse Relations

no code implementations COLING 2022 René Knaebel, Manfred Stede

The task of shallow discourse parsing in the Penn Discourse Treebank (PDTB) framework has traditionally been restricted to identifying those relations that are signaled by a discourse connective (“explicit”) and those that have no signal at all (“implicit”).

Extractive Summarisation for German-language Data: A Text-level Approach with Discourse Features

2 code implementations COLING 2022 Freya Hewett, Manfred Stede

Exploiting a lexical resource for discourse connective disambiguation in German

Variation in Coreference Strategies across Genres and Production Media

1 code implementation COLING 2020 Berfin Akta{\c{s}}, Manfred Stede

In response to (i) inconclusive results in the literature as to the properties of coreference chains in written versus spoken language, and (ii) a general lack of work on automatic coreference resolution on both spoken language and social media, we undertake a corpus study involving the various genre sections of Ontonotes, the Switchboard corpus, and a corpus of Twitter conversations.

Shallow Discourse Parsing for Under-Resourced Languages: Combining Machine Translation and Annotation Projection

no code implementations LREC 2020 Henny Sluyter-G{\"a}thje, Peter Bourgonje, Manfred Stede

Shallow Discourse Parsing (SDP), the identification of coherence relations between text spans, relies on large amounts of training data, which so far exists only for English - any other language is in this respect an under-resourced one.

Computational Argumentation Synthesis as a Language Modeling Task

no code implementations WS 2019 Roxanne El Baff, Henning Wachsmuth, Khalid Al Khatib, Manfred Stede, Benno Stein

Synthesis approaches in computational argumentation so far are restricted to generating claim-like argument units or short summaries of debates.

The Utility of Discourse Parsing Features for Predicting Argumentation Structure

no code implementations WS 2019 Freya Hewett, Roshan Prakash Rane, Nina Harlacher, Manfred Stede

Research on argumentation mining from text has frequently discussed relationships to discourse parsing, but few empirical results are available so far.

Automated Cross-language Intelligibility Analysis of Parkinson's Disease Patients Using Speech Recognition Technologies

no code implementations ACL 2019 Nina Hosseini-Kivanani, Juan Camilo V{\'a}squez-Correa, Manfred Stede, Elmar N{\"o}th

In the present study, we plan to analyze the speech signals of PD patients and healthy control (HC) subjects in three different languages: German, Spanish, and Czech, with the aim to identify biomarkers to discriminate between PD patients and HC subjects and to evaluate the neurological state of the patients.

Annotating Shallow Discourse Relations in Twitter Conversations

no code implementations WS 2019 Tatjana Scheffler, Berfin Akta{\c{s}}, Debopam Das, Manfred Stede

We confirm our hypothesis that discourse relations in written social media conversations are expressed differently than in (news) text.

Coherence models in schizophrenia

no code implementations WS 2019 S Just, ra, Erik Haegert, Nora Ko{\v{r}}{\'a}nov{\'a}, Anna-Lena Br{\"o}cker, Ivan Nenchev, Jakob Funcke, Christiane Montag, Manfred Stede

Speech samples were obtained from healthy controls and patients with a diagnosis of schizophrenia or schizoaffective disorder and different severity of positive formal thought disorder.

More or less controlled elicitation of argumentative text: Enlarging a microtext corpus via crowdsourcing

no code implementations WS 2018 Maria Skeppstedt, Andreas Peldszus, Manfred Stede

We present an extension of an annotated corpus of short argumentative texts that had originally been built in a controlled text production experiment.

Towards assessing depth of argumentation

no code implementations COLING 2016 Manfred Stede

For analyzing argumentative text, we propose to study the {`}depth{'} of argumentation as one important component, which we distinguish from argument quality.

Generating Sentiment Lexicons for German Twitter

1 code implementation WS 2016 Uladzimir Sidarenka, Manfred Stede

Despite a substantial progress made in developing new sentiment lexicon generation (SLG) methods for English, the task of transferring these approaches to other languages and domains in a sound way still remains open.
