    Information Retrieval and Visualization for the Historical Domain2011In: Language Technology for Cultural Heritage: Selected Papers from the LaTeCH Workshop Series / [ed] Sporleder, Caroline; van den Bosch, Antal; Zervanou, Kalliopi, Berlin, Heidelberg: Springer Berlin/Heidelberg, 2011, p. 197-212Chapter in book (Other academic)
    Abstract [en]

    Working with large and unstructured collections of historical documents is a challenging task for historians. Despite the recent growth in the volume of digitized historical data, available collections are rarely accompanied by computational tools that significantly facilitate this task.We address this shortage by proposing a visualization method for document collections that focuses on graphical representation of similarities between documents. The strength of the similarities is measured according to the overlap of historically significant information such as named entities,or the overlap of general vocabulary. Similarity strengths are then encoded in the edges of a graph.The graph provides visual structure, revealing interpretable clusters and links between documents that are otherwise difficult to establish. We implement the idea of similarity graphs within an information retrieval system supported by an interactive graphical user interface. The system allows querying the database, visualizing the results and browsing the collection in an effective and intuitive way. Our approach can be easy adapted and extended to collections of documents in other domains.

    FARMI: A Framework for Recording Multi-Modal Interactions2018In: Proceedings of the Eleventh International Conference on Language Resources and Evaluation (LREC 2018), Paris: European Language Resources Association, 2018, p. 3969-3974Conference paper (Refereed)
    Abstract [en]

    In this paper we present (1) a processing architecture used to collect multi-modal sensor data, both for corpora collection and real-time processing, (2) an open-source implementation thereof and (3) a use-case where we deploy the architecture in a multi-party deception game, featuring six human players and one robot. The architecture is agnostic to the choice of hardware (e.g. microphones, cameras, etc.) and programming languages, although our implementation is mostly written in Python. In our use-case, different methods of capturing verbal and non-verbal cues from the participants were used. These were processed in real-time and used to inform the robot about the participants’ deceptive behaviour. The framework is of particular interest for researchers who are interested in the collection of multi-party, richly recorded corpora and the design of conversational systems. Moreover for researchers who are interested in human-robot interaction the available modules offer the possibility to easily create both autonomous and wizard-of-Oz interactions.

    Making sense of adjectives: association vs. ascription in a family-resemblance model of semantic inheritance2010In: SKASE Journal of Theoretical Linguistics, E-ISSN 1336-782X, Vol. 7, no 3, p. 2-18Article in journal (Refereed)
    Abstract [en]

    Associative adjectives such as in electrical engineer differ from ascriptive adjectives like in red house: They are syntactically similar, yet they do not denote an intersective sense like ascriptive adjectives do. However, associative adjectives may (irregularly) denote ascriptive traits connected to the associated entity: The more semantically-similar two entities are, the more regular the traits are which are ascribed to them through association by a given adjective. This model of entities associated through family membership is analogous to a semantic network based on relative word similarities, in which families appear as clusters of relatively-similar entities.

    KTH Tangrams: A Dataset for Research on Alignment and Conceptual Pacts in Task-Oriented Dialogue2019In: LREC 2018 - 11th International Conference on Language Resources and Evaluation, Tokyo, 2019, p. 768-775Conference paper (Refereed)
    Abstract [en]

    There is a growing body of research focused on task-oriented instructor-manipulator dialogue, whereby one dialogue participant initiates a reference to an entity in a common environment while the other participant must resolve this reference in order to manipulate said entity. Many of these works are based on disparate if nevertheless similar datasets. This paper described an English corpus of referring expressions in relatively free, unrestricted dialogue with physical features generated in a simulation, which facilitate analysis of dialogic linguistic phenomena regarding alignment in the formation of referring expressions known as conceptual pacts.

    Knowledge-Based Word Lattice Rescoring in a Dynamic Context2012In: 13th Annual Conference of the International Speech Communication Association 2012, INTERSPEECH 2012, Portland, OR, USA: International Speech Communication Association, 2012, p. 1082-1085Conference paper (Refereed)
    Abstract [en]

    Recent advances in automatic speech recognition (ASR) technology continue to be based heavily on data-driven methods, meaning that the full benefits of such research are often not enjoyed in domains for which there is little training data. Moreover, tractability is often an issue with these methods when conditioning for long-distance dependencies, entailing that many higher-level knowledge sources such as situational knowledge cannot be easily utilized in classification. This paper describes an effort to circumvent this problem by using dynamic contextual knowledge to rescore ASR lattice output using a dynamic weighted constraint satisfaction function. With this method, it was possible to achieve a roughly 80% reduction in WER for ASR in the context of an air traffic control scenario.

    Enhancing reference resolution in dialogue using participant feedback2017In: Proc. GLU 2017 International Workshop on Grounding Language Understanding, Stockholm, Sweden: International Speech Communication Association, 2017, p. 78-82Conference paper (Refereed)
    Abstract [en]

    Expressions used to refer to entities in a common environment do not originate solely from one participant in a dialogue but are formed collaboratively. It is possible to train a model for resolving these referring expressions (REs) in a static manner using an appropriate corpus, but, due to the collaborative nature of their formation, REs are highly dependent not only on attributes of the referent in question (e.g. color, shape) but also on the dialogue participants themselves. As a proof of concept, we improved the accuracy of a words-as-classifiers logistic regression  model  by  incorporating  knowledge about  accepting/rejecting REs proposed from other participants.

    Using lexical alignment and referring ability to address data sparsity in situated dialog reference resolution2020In: Proceedings of the 2018 Conference on Empirical Methods in Natural Language Processing, EMNLP 2018, Association for Computational Linguistics , 2020, p. 2288-2297Conference paper (Refereed)
    Abstract [en]

    Referring to entities in situated dialog is a collaborative process, whereby interlocutors often expand, repair and/or replace referring expressions in an iterative process, converging on conceptual pacts of referring language use in doing so. Nevertheless, much work on exophoric reference resolution (i.e. resolution of references to entities outside of a given text) follows a literary model, whereby individual referring expressions are interpreted as unique identifiers of their referents given the state of the dialog the referring expression is initiated. In this paper, we address this collaborative nature to improve dialogic reference resolution in two ways: First, we trained a words-as-classifiers logistic regression model of word semantics and incrementally adapt the model to idiosyncratic language between dyad partners during evaluation of the dialog. We then used these semantic models to learn the general referring ability of each word, which is independent of referent features. These methods facilitate accurate automatic reference resolution in situated dialog without annotation of referring expressions, even with little background data.
