Subject

My research interests are centered around linguistic and philosophical theories of meaning and interaction. One focus is on the interplay of speech and gesture in communication. In my work, I combine theoretical modeling and experimental methods. The domains covered range from foundational theoretical aspects of grounding non-verbal meaning to the building of applications. I am concerned with topics such as semantic and pragmatic notions of reference, deferred reference, alignment in dialogue, iconicity, demonstration and exemplification.

[Abstract] [BibTeX]

This chapter develops a computational linguistic model for analyzing and comparing multilingual data as well as its application to a large body of standardized assessment data from higher education. The approach employs both an automatic and a manual annotation of the data on several linguistic layers (including parts of speech, text structure and content). Quantitative features of the textual data are explored that are related to both the students’ (domain-specific knowledge) test results and their level of academic experience. The respective analysis involves statistics of distance correlation, text categorization with respect to text types (questions and distractors) as well as languages (English and German), and network analysis as a means to assess dependencies between features. The results indicate a correlation between correct test results of students and linguistic features of the verbal presentations of tests indicating a language influence on higher education test performance. It is also found that this influence relates to special language. Thus, this integrative modeling approach contributes a test basis for a large-scale analysis of learning data and points to a number of subsequent more detailed research.

[Abstract] [BibTeX]

Current semantic theory on indexical expressions claims that demonstratively used indexicals such as this lack a referent-determining meaning but instead rely on an accompanying demonstration act like a pointing gesture. While this view allows to set up a sound logic of demonstratives, the direct-referential role assigned to pointing gestures has never been scrutinized thoroughly in semantics or pragmatics. We investigate the semantics and pragmatics of co-verbal pointing from a foundational perspective combining experiments, statistical investigation, computer simulation and theoretical modeling techniques in a novel manner. We evaluate various referential hypotheses with a corpus of object identification games set up in experiments in which body movement tracking techniques have been extensively used to generate precise pointing  measurements. Statistical investigation and computer simulations show that especially distal areas in the pointing domain falsify the semantic direct-referential hypotheses concerning pointing gestures. As an alternative, we propose that reference involving pointing rests on a default inference which we specify using the empirical data. These results raise numerous problems for classical semantics–pragmatics interfaces: we argue for pre-semantic pragmatics in order to account for inferential reference in addition to classical post-semantic Gricean pragmatics.

[Abstract] [BibTeX]

This paper provides a theoretical assessment of gestures in the context of authoring image-related hypertexts by example of the museum information system WikiNect. To this end, a first implementation of gestural writing based on image schemata is provided (Lakoff in Women, fire, and dangerous things: what categories reveal about the mind. University of Chicago Press, Chicago, 1987). Gestural writing is defined as a sort of coding in which propositions are only expressed by means of gestures. In this respect, it is shown that image schemata allow for bridging between natural language predicates and gestural manifestations. Further, it is demonstrated that gestural writing primarily focuses on the perceptual level of image descriptions (Hollink et al. in Int J Hum Comput Stud 61(5):601–626, 2004). By exploring the metaphorical potential of image schemata, it is finally illustrated how to extend the expressiveness of gestural writing in order to reach the conceptual level of image descriptions. In this context, the paper paves the way for implementing museum information systems like WikiNect as systems of kinetic hypertext authoring based on full-fledged gestural writing.

We provide a new, theoretically motivated evaluation grid for assessing the conversational achievements of Artificial Dialog Companions (ADCs). The grid is spanned along three grounding problems. Firstly, it is argued that symbol grounding in general has to be instrinsic. Current approaches in this context, however, are limited to a certain kind of expression that can be grounded in this way. Secondly, we identify three requirements for conversational grounding, the process leading to mutual understanding. Finally, we sketch a test case for symbol grounding in the form of the philosophical grounding problem that involves the use of modal language. Together, the three grounding problems provide a grid that allows us to assess ADCs’ dialogical performances and to pinpoint future developments on these grounds.

Communicating face-to-face, interlocutors frequently produce multimodal meaning packages consisting of speech and accompanying gestures.

We first describe the primary and secondary data of the corpus and its reliability assessment. Then we go into some of the projects carried out using SaGA demonstrating the wide range of its usability: on the empirical side, there is work on gesture typology, individual and contextual parameters influencing gesture production and gestures’ functions for dialogue structure. Speech-gesture interfaces have been established extending unification-based grammars. In addition, the development of a computational model of speech-gesture alignment and its implementation constitutes a research line we focus on.

[Abstract] [BibTeX]

We present an empirical account of multimodal ensembles based on Hjelmslev’s notion of selection. This is done to get measurable evidence for the existence of speech-and-gesture ensembles. Utilizing information theory, we show that there is an information transmission that makes a gestures’ representation technique predictable when merely knowing its lexical affiliate – in line with the notion of the primacy of language. Thus, there is evidence for a one-way coupling – going from words to gestures – that leads to speech-and-gesture alignment and underlies the constitution of multimodal ensembles.

[Abstract] [BibTeX]

A framework for grounding the semantics of co-verbal iconic gestures is presented. A resemblance account to iconicity is discarded in favor of an exemplification approach. It is sketched how exemplification can be captured within a unification-based grammar that provides a conceptual interface. Gestures modeled as vector sequences are the exemplificational base. Some hypotheses that follow from the general account are pointed at and remaining challenges are discussed.

[Abstract] [BibTeX]

We introduce WikiNect as a kinetic museum information system that allows museum visitors to give on-site feedback about exhibitions. To this end, WikiNect integrates three approaches to Human-Computer Interaction (HCI): games with a purpose, wiki-based collaborative writing and kinetic text-technologies. Our aim is to develop kinetic technologies as a new paradigm of HCI. They dispense with classical interfaces (e.g., keyboards) in that they build on non-contact modes of communication like gestures or facial expressions as input displays. In this paper, we introduce the notion of gestural writing as a kinetic text-technology that underlies WikiNect to enable museum visitors to communicate their feedback. The basic idea is to explore sequences of gestures that share the semantic expressivity of verbally manifested speech acts. Our task is to identify such gestures that are learnable on-site in the usage scenario of WikiNect. This is done by referring to so-called transient gestures as part of multimodal ensembles, which are candidate gestures of the desired functionality.

Staccato, the Segmentation Agreement Calculator According to Thomann , is a software tool for assessing the degree of agreement of multiple segmentations of some time-related data (e.g., gesture phases or sign language constituents). The software implements an assessment procedure developed by Bruno Thomann and will be made publicly available. The article discusses the rationale of the agreement assessment procedure and points at future extensions of Staccato.

[Abstract] [BibTeX]

We present a network model of dialog lexica, called TiTAN (Two-layer Time-Aligned Network) series. TiTAN  series capture the formation and structure of dialog lexica in terms of serialized graph representations. The dynamic update of TiTAN  series is driven by the dialog-inherent timing of turn-taking. The model provides a link between neural, connectionist underpinnings of dialog lexica on the one hand and observable symbolic behavior on the other. On the neural side, priming and spreading activation are modeled in terms of TiTAN networking. On the symbolic side, TiTAN  series account for cognitive alignment in terms of the structural coupling of the linguistic representations of dialog partners. This structural stance allows us to apply TiTAN  in machine learning of data of dialogical alignment. In previous studies, it has been shown that aligned dialogs can be distinguished from non-aligned ones by means of TiTAN -based modeling. Now, we simultaneously apply this model to two types of dialog: task-oriented, experimentally controlled dialogs on the one hand and more spontaneous, direction giving dialogs on the other. We ask whether it is possible to separate aligned dialogs from non-aligned ones in a type-crossing way. Starting from a recent experiment (Mehler, Lücking, & Menke, 2011a), we show that such a type-crossing classification is indeed possible. This hints at a structural fingerprint left by alignment in networks of linguistic items that are routinely co-activated during conversation.

[Abstract] [BibTeX]

The Naming Game (NG) has become a vivid research paradigm for simulation studies on language evolution and the establishment of naming conventions. Recently, NGs were used for reconstructing the creation of linguistic categories, most notably for color terms. We recap the functional principle of NGs and the latter Categorization Games (CGs) and evaluate them in the light of semantic data of linguistic categorization outside the domain of colors. This comparison reveals two specifics of the CG paradigm: Firstly, the emerging categories draw basically on the predefined topology of the learning domain. Secondly, the kind of categories that can be learnt in CGs is bound to context-independent intersective categories. This suggests that the NG and the CG focus on a special aspect of natural language categorization, which disregards context-sensitive categories used in a non-compositional manner.

The SoSaBiEC corpus is comprised audio recordings of everyday interactions between familiar subjects. Thus, the material the corpus is based on is not gained in task-oriented dialogue under strict experimental control; rather, it is made up of spontaneous conversations. We describe the raw data and the annotations that constitute the corpus. Speech is transcribed at the level of words. Dialogue act oriented codings constitute a functional, qualitative annotation level. The corpus so far provides an empirical basis for studying social aspects of unrestricted language use in a familiar context .

[Abstract] [BibTeX]

We conducted a two-part study that contributes to the discussion about cervical auscultation (CA) as a scientifically justifiable and medically useful tool to identify patients with a high risk of aspiration/penetration. We sought to determine (1) acoustic features that mark a deglutition act as dysphagic; (2) acoustic changes in healthy older deglutition profiles compared with those of younger adults; (3) the correctness and concordance of rater judgments based on CA; and (4) if education in CA improves individual reliability. The first part of the study focused on a comparison of the swallow morphology of dysphagic as opposed to healthy subjects� deglutition in terms of structure properties of the pharyngeal phase of deglutition. We obtained the following results. The duration of deglutition apnea is significantly higher in the older group than in the younger one. Comparing the younger group and the dysphagic group we found significant differences in duration of deglutition apnea, onset time, and number of gulps. Just one parameter, number of gulps, distinguishes significantly between the older and the dysphagic groups. The second part of the study aimed at evaluating the reliability of CA in detecting dysphagia measured as the concordance and the correctness of CA experts in classifying swallowing sounds. The interrater reliability coefficient AC1 resulted in a value of 0.46, which is to be interpreted as fair agreement. Furthermore, we found that comparison with radiologically defined aspiration/penetration for the group of experts (speech and language therapists) yielded 70% specificity and 94% sensitivity. We conclude that the swallowing sounds contain audible cues that should, in principle, permit reliable classification and view CA as an early warning system for identifying patients with a high risk of aspiration/penetration; however, it is not appropriate as a stand-alone tool.

In our setting we employed methodological and technical procedures of a new type to integrate data from annotations as well as from tracker recordings. We combined exact information on position and orientation with rater’s classifications. Our first results seem to challenge classical linguistic and philosophical theories of demonstration in that they advise to separate pointings from reference.

[Abstract] [BibTeX]

Demonstratives, in particular gestures that 'only' accompany speech, are not a big issue in current theories of grammar. If we deal with gestures, fixing their function is one big problem, the other one is how to integrate the representations originating from different channels and, ultimately, how to determine their composite meanings. The growing interest in multi-modal settings, computer simulations, human-machine interfaces and VR-applications increases the need for theories of multi-modal structures and events. In our workshop-contribution we focus on the integration of multi-modal contents and investigate different approaches dealing with this problem such as Johnston et al. (1997) and Johnston (1998), Johnston and Bangalore (2000), Chierchia (1995), Asher (2005), and Rieser (2005).

[Abstract] [BibTeX]

This chapter presents an original approach towards a detailed understanding of the usage of pointing gestures accompanying referring expressions. This effort is undertaken in the context of human-machine interaction integrating empirical studies, theory of grammar and logics, and simulation techniques. In particular, we take steps to classify the role of pointing in deictic expressions and to model the focussed area of pointing gestures, the so-called pointing cone. This pointing cone serves as a central concept in a formal account of multi-modal integration at the linguistic speech-gesture interface as well as in a computational model of processing multi-modal deictic expressions.

[Abstract] [BibTeX]

We present a collaborative approach towards a detailed understanding of the usage of pointing gestures accompanying referring expressions. This effort is undertaken in the context of human-machine interaction integrating empirical studies, theory of grammar and logics, and simulation techniques. In particular, we attempt to measure the precision of the focussed area of a pointing gesture, the so-called pointing cone. The pointing cone serves as a central concept in a formal account of multi-modal integration at the linguistic speech-gesture interface as well as in a computational model of processing multi-modal deictic expressions.

[Abstract] [BibTeX]

Für die empirische Erforschung natürlicher menschlicher Kommunikation sind wir auf die Akquise und Auswertung umfangreicher Daten angewiesen. Die Modalitäten, über die sich Menschen ausdrücken können, sind sehr unterschiedlich - und genauso verschieden sind die Repräsentationen, mit denen sie für die Empirie verfügbar gemacht werden können. Für eine Untersuchung des Zeigeverhaltens bei der Referenzierung von Objekten haben wir mit IADE ein Framework für die Aufzeichnung, Analyse und Resimulation von Sprach-Gestik Daten entwickelt. Mit dessen Hilfe können wir für unsere Forschung entscheidende Fortschritte in der linguistischen Experimentalmethodik machen.

[Abstract] [BibTeX]

We present a statistical approach to assess relations that hold among speech and pointing gestures in and between turns in task-oriented dialogue. The units quantified over are the time-stamps of the XML-based annotation of the digital video data. It was found that, on average, gesture strokes do not exceed, but are freely distributed over the time span of their linguistic affiliates. Further, the onset of the affiliate was observed to occur earlier than gesture initiation. Moreover, we found that gestures do obey certain appropriateness conditions and contribute semantic content ('gestures save words') as well. Gestures also seem to play a functional role wrt dialogue structure: There is evidence that gestures can contribute to the bundle of features making up a turn-taking signal. Some statistical results support a partitioning of the domain, which is also reflected in certain rating difficulties. However, our evaluation of the applied annotation scheme generally resulted in very good agreement

Since January 2011, I am a research assistant at the Text Technology Lab at the Goethe University Frankfurt.

I studied linguistics, philosophy and German philology at Bielefeld University. During my studies, I worked as scientific assistant in several projects:

1. B1 “Speech-Gesture Alignment” in the Collaborative Research Center 673 “Alignment in Communication” (June 2006 to January 2011). In this project, I contributed in building the Speech-and-Gesture Alignment Corpus (SaGA). I also developed an account for the meaning of co-verbal iconic gestures and how they interact with speech (see dissertation.).
2. Linguistic Networks (September 2009 to December 2010).
3. Research Unit 437 “Text Technological Modelling of Information”, project A2 Secondary structuring of information and comparative analysis of discourse (Sekimo) (April 2006 to September 2006). In this short-term engagement, I supported the annotation of discourse structure and centering relations, and the assessment of reliability.
4. Project B3 “Deixis in Construction Dialogues” of the Collaborative Research Center 360 “Situated Artificial Communicators” (2005). In this project, I participated in investigating the role of pointing in demonstrative reference in task-oriented dialogue.

In 2011, I received my PhD in linguistics at Bielefeld University for my prolegomena for a linguistic theory of co-verbal iconic gesture. The work has been published in 2013 as “Ikonische Gesten. Grundzüge einer linguistischen Theorie”.

I am a member of the Deutsche Gesellschaft für Sprachwissenschaft (DGfS).

Besides my research activities, I am interested in typesetting with LaTeX. I am a member of the German TeX User Society (Deutsche Anwendervereinigung TeX, DANTE).
