In conversation, turn-taking is usually fluid, with next speakers taking their turn right after the end of the previous turn. Most, but not all, previous studies show that next speakers start to plan their turn early, if possible already during the incoming turn. The present study makes use of the list-completion paradigm (Barthel et al., 2016), analyzing speech onset latencies and eye-movements of participants in a task-oriented dialogue with a confederate. The measures are used to disentangle the contributions to the timing of turn-taking of early planning of content on the one hand and initiation of articulation as a reaction to the upcoming turn-end on the other hand. Participants named objects visible on their computer screen in response to utterances that did, or did not, contain lexical and prosodic cues to the end of the incoming turn. In the presence of an early lexical cue, participants showed earlier gaze shifts toward the target objects and responded faster than in its absence, whereas the presence of a late intonational cue only led to faster response times and did not affect the timing of participants' eye movements. The results show that with a combination of eye-movement and turn-transition time measures it is possible to tease apart the effects of early planning and response initiation on turn timing. They are consistent with models of turn-taking that assume that next speakers (a) start planning their response as soon as the incoming turn's message can be understood and (b) monitor the incoming turn for cues to turn-completion so as to initiate their response when turn-transition becomes relevant.
Our paper describes an experiment aimed to assessment of lexical coverage in web corpora in comparison with the traditional ones for two closely related Slavic languages from the lexicographers’ perspective. The preliminary results show that web corpora should not be considered ― inferior, but rather ― different.
Language of Responsibility. The Influence of Linguistic Abstraction on Collective Moral Emotions
(2017)
Two experiments investigated the effects of linguistic abstractness on the experience of collective moral emotions. In Experiment 1 participants were presented with two scenarios about ingroup misbehavior, phrased using descriptive action verbs, interpretative action verbs, adjectives or nouns. The results show that participants experienced slightly more negative moral emotions with higher levels of linguistic abstractness. In Experiment 2 we also tested for the influence of national identification on the relationship between linguistic abstractness and emotional reactions. Additionally, we expanded the number of scenarios. Experiment 2 replicated the earlier pattern, but found larger differences between conditions. The strength of national identification did not moderate the observed effects. The results of this research are discussed within the context of the linguistic category model and psychology of collective moral emotions.
While good results have been achieved for named entity recognition (NER) in supervised settings, it remains a problem that for low resource languages and less studied domains little or no labelled data is available. As NER is a crucial preprocessing step for many natural language processing tasks, finding a way to overcome this deficit in data remains of great interest. We propose a distant supervision approach to NER that is both language and domain independent where we automatically generate labelled training data using gazetteers that we previously extracted from Wikipedia. We test our approach on English, German and Estonian data sets and contribute further by introducing several successful methods to reduce the noise in the generated training data. The tested models beat baseline systems and our results show that distant supervision can be a promising approach for NER when no labelled data is available. For the English model we also show that the distant supervision model is better at generalizing within the same domain of news texts by comparing it against a supervised model on a different test set.
Many (modernist) works of literature can be understood by their associativeness, be it constructed or “free”. This network-like character of (modernist) literature has often been addressed by terms like “free association”, connotation”, “context” or “intertext”. This paper proposes an experimental and exemplary approach to intraconnect a literary corpus of the Austrian writer Ilse Aichinger with semantic web-technologies to enable interactive explorations of word-associations.
This paper reports about current practice in a staged approach to the introduction of NLP principles and techniques for students of information science (IIM) and of international communication and translation (ICT) as part of their curricula. As most of these students are rather not familiar with computer science or, in the case of IIM students, linguistics, we see them as comparable with students of the humanities. We follow a blended learning strategy with lectures, online materials, tutorials, and screencasts. In the first two terms, we focus on linguistics and its formalisation, NLP tools and applications are then introduced from the third term on. The lectures are combined with tutorials and - since the summer term 2017 - with a set of screencasts.
Basic grammatical categories may carry social meanings irrespective of their semantic content. In a set of four studies, we demonstrate that verbs—a basic linguistic category present and distinguishable in most languages—are related to the perception of agency, a fundamental dimension of social perception. In an archival analysis of actual language use in Polish and German, we found that targets stereotypically associated with high agency (men and young people) are presented in the immediate neighborhood of a verb more often than non-agentic social targets (women and older people). Moreover, in three experiments using a pseudo-word paradigm, verbs (but not adjectives and nouns) were consistently associated with agency (but not with communion). These results provide consistent evidence that verbs, as grammatical vehicles of action, are linguistic markers of agency. In demonstrating meta-semantic effects of language, these studies corroborate the view of language as a social tool and an integral part of social perception.
Telicity and agentivity are semantic factors that split intransitive verbs into (at least two) different classes. Clear-cut unergative verbs, which select the auxiliary HAVE, are assumed to be atelic and agent-selecting; unequivocally unaccusative verbs, which select the auxiliary BE, are analyzed as telic and patient-selecting. Thus, agentivity and telicity are assumed to be inversely correlated in split intransitivity. We will present semantic and experimental evidence from German and Mandarin Chinese that casts doubts on this widely held assumption. The focus of our experimental investigation lies on variation with respect to agentivity (specifically motion control, manipulated via animacy), telicity (tested via a locative vs. goal adverbial), and BE/HAVE-selection with semantically flexible intransitive verbs of motion. Our experimental methods are acceptability ratings for German and Chinese (Experiments 1 and 2) and event-related potential (ERP) measures for German (Experiment 3). Our findings contradict the above-mentioned assumption that agentivity and telicity are generally inversely correlated and suggest that for the verbs under study, agentivity and telicity harmonize with each other. Furthermore, the ERP measures reveal that the impact of the interaction under discussion is more pronounced on the verb lexeme than on the auxiliary. We also found differences between Chinese and German that relate to the influence of telicity on BE/HAVE-selection. They seem to confirm the claim in previous research that the weight of the telicity factor locomotion (or internal motion) is cross-linguistically variable.
This paper provides insights into the ongoing international research project Unserdeutsch (Rabaul Creole German): Documentation of a highly endangered creole language in Papua New Guinea, based at the University of Augsburg, Germany. It elaborates on the different stages of the project, ranging from fieldwork to corpus development, thereby outlining the methods and software background used for the intended purposes. In doing so, we also give some approaches to solving specific problems, which have arisen in the course of practical work until now.
Most research on ethnicity has focused on visual cues. However, accents are strong social cues that can match or contradict visual cues. We examined understudied reactions to people whose one cue suggests one ethnicity, whereas the other cue contradicts it. In an experiment conducted in Germany, job candidates spoke with an accent either congruent or incongruent with their (German or Turkish) appearance. Based on ethnolinguistic identity theory, we predicted that accents would be strong cues for categorization and evaluation. Based on expectancy violations theory we expected that incongruent targets would be evaluated more extremely than congruent targets. Both predictions were confirmed: accents strongly influenced perceptions and Turkish-looking German-accented targets were perceived as most competent of all targets (and additionally most warm). The findings show that bringing together visual and auditory information yields a more complete picture of the processes underlying impression formation.
