    WILD 2015: Book of Abstracts2015Konferanseproceedings (Annet vitenskapelig)
    Abstract [en]

    WILD 2015 is the second Workshop on Infant Language Development, held June 10-12 2015 in Stockholm, Sweden. WILD 2015 was organized by Stockholm Babylab and the Department of Linguistics, Stockholm University. About 150 delegates met over three conference days, convening on infant speech perception, social factors of language acquisition, bilingual language development in infancy, early language comprehension and lexical development, neurodevelopmental aspects of language acquisition, methodological issues in infant language research, modeling infant language development, early speech production, and infant-directed speech. Keynote speakers were Alejandrina Cristia, Linda Polka, Ghislaine Dehaene-Lambertz, Angela D. Friederici and Paula Fikkert.

    Organizing this conference would of course not have been possible without our funding agencies Vetenskapsrådet and Riksbankens Jubiléumsfond. We would like to thank Francisco Lacerda, Head of the Department of Linguistics, and the Departmental Board for agreeing to host WILD this year. We would also like to thank the administrative staff for their help and support in this undertaking, especially Ann Lorentz-Baarman and Linda Habermann.

    The WILD 2015 Organizing Committee: Ellen Marklund, Iris-Corinna Schwarz, Elísabet Eir Cortes, Johan Sjons, Ulrika Marklund, Tove Gerholm, Kristina Nilsson Björkenstam and Monika Molnar.

    Identifying Speakers and Addressees in Dialogues Extracted from Literary Fiction2018Inngår i: Proceedings of the Eleventh International Conference on Language Resources and Evaluation (LREC-2018) / [ed] Nicoletta Calzolari, Khalid Choukri, Christopher Cieri, Thierry Declerck, Koiti Hasida, Hitoshi Isahara, Bente Maegaard, Joseph Mariani, Asuncion Moreno, Jan Odijk, Stelios Piperidis, Takenobu Tokunaga, European Language Resources Association, 2018, s. 817-824Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper describes an approach to identifying speakers and addressees in dialogues extracted from literary fiction, along with a dataset annotated for speaker and addressee. The overall purpose of this is to provide annotation of dialogue interaction between characters in literary corpora in order to allow for enriched search facilities and construction of social networks from the corpora. To predict speakers and addressees in a dialogue, we use a sequence labeling approach applied to a given set of characters. We use features relating to the current dialogue, the preceding narrative, and the complete preceding context. The results indicate that even with a small amount of training data, it is possible to build a fairly accurate classifier for speaker and addressee identification across different authors, though the identification of addressees is the more difficult task.

    Language-independent exploration of repetition and variation in longitudinal child-directed speech: A tool and resources2016Inngår i: Proceedings of the joint workshop on NLP for Computer Assisted Language Learning and NLP for Language Acquisition at SLTC, Umeå, 16th November 2016 / [ed] Elena Volodina, Gintarė Grigonytė, Ildikó Pilán, Kristina Nilsson Björkenstam, Lars Borin, Linköping: Linköping University Electronic Press, 2016, s. 41-50Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We present a language-independent tool, called Varseta, for extracting variation sets in child-directed speech. This tool is evaluated against a gold standard corpus annotated with variation sets, MINGLE-3-VS, and used to explore variation sets in 26 languages in CHILDES-26-VS, a comparable corpus derived from the CHILDES database. The tool and the resources are freely available for re-search.

    Frequency filter: an open access tool for analysing language development2018Inngår i: Language, Cognition and Neuroscience, ISSN 2327-3798, E-ISSN 2327-3801, Vol. 33, nr 10, s. 1325-1339Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We present an open-access analytic tool, which allows researchers to simultaneously control for and combine language data from the child, the caregiver, multiple languages, and across multiple time points to make inferences about the social and cognitive factors driving the shape of language development. We demonstrate how the tool works in three domains of language learning and across six languages. The results demonstrate the usefulness of this approach as well as providing deeper insight into three areas of language production and acquisition: egocentric language use, the learnability of nouns versus verbs, and imageability. We have made the Frequency Filter tool freely available as an R-package for other researchers to use at https://github.com/rosemm/FrequencyFilter.

    SUC-CORE: A Balanced Corpus Annotated with Noun Phrase Coreference2013Inngår i: Northern European Journal of Language Technology (NEJLT), ISSN 2000-1533, Vol. 3, nr 2, s. 19-39Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper describes SUC-CORE, a subset of the Stockholm Umeå Corpus and the Swedish Treebank annotated with noun phrase coreference. While most coreference annotated corpora consist of texts of similar types within related domains, SUC-CORE consists of both informative and imaginative prose and covers a wide range of literary genres and domains.This allows for exploration of coreference across different text types, but it also means that there are limited amounts of data within each type. Future work on coreference resolution for Swedish should include making more annotated data available for the research community.

    The MINGLE annotation scheme: Multimodal annotation of parent-child interation in a free play setting (version 1.0)2012Rapport (Annet vitenskapelig)
    Abstract [en]

    A cognitive model of language learning must be dialogue-driven and multimodal to reflect how parent and child interact, using words, eye gaze, and object manipulation. We present a scheme for multimodal annotation of parent-child interaction. The purpose is to add verbal and non-verbal annotation to a corpus of longitudinal video and sound recordings of parent-child dyads. In this guideline, we describe the transcription of adult and child speech and vocalizations, and the annotation of both empty-hand gestures and object-related actions by both adults and children.

    The Stockholm University Strindberg Corpus: Content and Possibilities2014Inngår i: Strindberg on International Stages/Strindberg in Translation / [ed] Roland Lysell, Cambridge: Cambridge Scholars Publishing, 2014Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    We have approached the works of August Strindberg from  a computational linguistic point of view, resulting in The Stockholm University Strindberg Corpus, consisting of seven of Strindberg's autobiographical works with linguistic annotation. The corpus is freely available for research. We use this corpus for three quantitative studies of Strindberg’s work: in the first, we describe the novels included in the corpus by keywords; in the second, we compare Strindberg’s use of emotionally charged words with selected prose of both his contemporaries and present-day authors; in the third, we explore the semantic prosody of KVINNA (“woman”) and MAN (“man”).

    Stockholm University Strindberg Corpus: Contents and possibilities2012Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The Stockholm University Strindberg Corpus (SUSC) consists of seven novels by August Strindberg annotated for parts-of-speech with morphological analysis and lemmas. The corpus is freely available.

    SUSC consists of approximately 400 000 tokens annotated for parts-of-speech, including morphological analysis and lemmas, using the Stockholm-Umeå Corpus tag set in PAROLE-format. The annotated texts have been converted to XML which makes the corpus searchable with corpus analysis tools such as Xaira. This allows for e.g., searching for concordances with a specific wordform, part-of-speech and/or lemma, for pattern matching, and collocation extraction.

    The current version of the corpus includes seven works which can be classified as autobiographical:

    • Tjänstekvinnans son (The son of a servant, 1886-87)
    • Han och hon (He and she, 1919)
    • Inferno (Inferno, 1897)
    • Legender and Jakob brottas (Legends and Jacob wrestles, 1898)
    • Fagervik och Skamsund (Fair haven and Foulstrand, 1902)
    • Ensam (Alone, 1903)

    We are aware of three other electronic collections of Strindberg’s works: Projekt Runeberg, Litteraturbanken and Språkbanken. While these are valuable resources, SUSC is an important addition because, unlike the first two, it is linguistically annotated, and unlike the third, the data is available for download and thus can be fully inspected and processed using the researcher’s software of choice. Even more importantly, researchers can add their analyses as new layers of annotation of the corpus.

    En korpusstudie om multimodal synkroni i tidig ordinlärning2013Konferansepaper (Annet vitenskapelig)
    Abstract [sv]

    I denna studie undersöker vi synkroni i tidig multimodal interaktion mellan föräldrar och barn. Med synkroni menas här återkommande mönster eller strukturella regelbundenheter (vad gäller ord, prosodi, blickriktning, gester och handlingar) som kan reducera komplexitet i språkinlärning.

    Data består av inspelningar av fem longitudinella dyader med två barn (0;7-2;7 år) och deras föräldrar. Inspelningarna transkriberas och annoteras med grundtonsfrekvens, blickriktning, gester och hantering av objekt. Vi undersöker synkroni genom att studera samtliga omnämnanden av två valda objekt (två dockor). För varje omnämnande undersöks grundtonsfrekvens och om omnämnandet kombineras med att den vuxne/barnet tittar på, pekar mot eller rör objektet.

    Man tänker sig att barnet använder sig av grundläggande perceptuella processer för att ta fasta på mönster och regelbundenheter i interaktionen med den vuxne, både i den akustiska signalen men också i den fysiska omgivningen (Gogate & Hollich, 2010). Den vuxne är dessutom benägen att framhäva den språkliga strukturen i interaktion med barnet, t ex genom att den vuxne talar om ett objekt och samtidigt visar objektet för barnet eller låter barnet känna på objektet. Denna synkroniserade multimodala input blir en hjälp för barnet att strukturera och sortera talsignalen och göra kopplingar mellan ord och objekt. I den här studien vill vi försöka fånga den här typen av multimodal synkroni genom att studera två specifika målord och hur interaktionen ser ut just kring dessa ord. Vi tänker oss att regelbundenheter vad gäller prosodi, blickriktningar och gester kommer att vara mer synkroniserade när barnet är mindre och målorden nya, än när barnen är äldre och målorden bekanta.

    Studien är del av ett projekt där vi försöker förklara tidig språkinlärning utifrån generella sociala och kognitiva förmågor. Genom att studera tidig förälder-barn-interaktion vill vi undersöka hur språkliga konstruktioner växer fram, vilka funktioner de har och hur de korrelerar med andra stimuli i barnets omgivning.

    Abstract [en]

    This paper describes the verbal, non-verbal, and discourse annotation of a longitudinal corpus of parent-child interaction. The verbal annotation includes transcription of child-directed speech and child vocalizations. The non-verbal annotation describes gestures and objectrelatedactions by both parent and child. The verbal and non-verbal annotation is combined in discourse annotation that distinguishes initial from subsequent mentions, and further categorizes initial mentions depending on initiative.

    This paper describes the multimodal annotation of speech, gaze and hand movement in a corpus of longitudinal parent–child interaction,and reports results on synchrony, structural regularities which appear to be a key means for parents to facilitate learning of new conceptsto children. The results provide additional support for our previous finding that parents display decreasing synchrony as a function ofthe age of the child.

    Reference to Objects in Longitudinal Parent-Child Interaction2012Inngår i: Workshop on Language, Action and Perception (APL), 2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    A cognitive model of language learning needs to be dialogue-driven and multimodal to reflect how parent and child interact, using words, eye gaze, and object manipulation.

    In this paper, we present a scheme for multimodal annotation of parent-child interaction. We use this annotation for studying invariance across modalities. Our basic hypothesis is that perception of invariance (or synchrony) in multimodal patterns in auditory-visual speech is the device primarily used to reduce complexity in language learning.

    To this end, we have added verbal and non-verbal annotation to a corpus of longitudinal video and sound recordings of parent-child dyads. We use this data to try to determine if the amount of synchrony across modalities of parent-child interaction decreases as the child grows older and learns more language and gestures.

    Modelling the informativeness and timing of non-verbal cues in parent–child interaction2016Inngår i: The 54th Annual Meeting of the Association for Computational Linguistics: Proceedings of the 7th Workshop on Cognitive Aspects of Computational Language Learning, Stroudsburg, PA, USA: Association for Computational Linguistics, 2016, s. 82-90Konferansepaper (Fagfellevurdert)
    Abstract [en]

    How do infants learn the meanings of their first words? This study investigates the informativeness and temporal dynamics of non-verbal cues that signal the speaker's referent in a model of early word–referent mapping. To measure the information provided by such cues, a supervised classifier is trained on information extracted from a multimodally annotated corpus of 18 videos of parent–child interaction with three children aged 7 to 33 months. Contradicting previous research, we find that gaze is the single most informative cue, and we show that this finding can be attributed to our fine-grained temporal annotation. We also find that offsetting the timing of the non-verbal cues reduces accuracy, especially if the offset is negative. This is in line with previous research, and suggests that synchrony between verbal and non-verbal cues is important if they are to be perceived as causally related.

    Hybrid Methods for Coreference Resolution in Swedish2010Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    The aim of this thesis is to improve coreference resolution in Swedish by providing a hybrid approach based on combining data-driven methods and linguistic knowledge. Coreference resolution here consists in identifying all expressions in a text that have the same referent, for example, a person or an object.

    The linguistic knowledge is based on Accessibility Theory (Ariel 1990). This is used for guiding the  selection of likely anaphor-antecedent pairs from the set of all possible such pairs in a text. The data-driven method adopted is Memory-Based Learning (MBL), a supervised method based on the idea that learning means storing experiences in memory, and that new problems are solved by reusing solutions from similar experiences (Daelemans and Van den Bosch 2005).

    The referring expressions covered by the system are names, definite descriptions, and pronouns. In order to maximize performance, we use different classifiers with a specific set of linguistically motivated features for each type of expression. The great majority of features used for classification are domain- and language-independent.

    We demonstrate two ways of using this method of linguistically motivated selection of anaphor-antecedent pairs.

    First, the amount of training examples stored in memory  is reduced. We find that for coreference resolution of definite descriptions and names, the amount of training data can thereby be reduced with only a minor loss in performance, but for pronoun resolution there is a negative effect.

    Second, selection can be used for improving on coreference resolution results. This is the first step in our hybrid approach to coreference resolution, where the second step is the application of an MBL classifier for determining coreference between the selected pairs. Results indicate that this hybrid approach is advantageous for coreference resolution of definite descriptions and names. For pronoun resolution, there is a negative effect on recall along with a positive effect on precision.

    Living off the land:The Web as a source of practice texts for learners of less prevalent languages2002Inngår i: Third International Conference on Language Resources and Evaluation. Proceedings. Vol II. Las Palmas, Spain: ELRA. 2002., 2002, s. 411-418Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This study focuses on how to automatically locate text sources published on the World Wide Web in order to produce adequate and upto-date learning materials for second language learners of Nordic languages. The Web is an excellent source of authentic text materials.However, the large amount of information available on the Web makes search services necessary. Hence, we are developing Squirrel, aprototype Web meta-search service, described in this paper, which collects text material in the Nordic languages according to language,topic and difficulty level. Our primary target group consists of exchange students to Nordic institutions of higher education, and theirlanguage teachers, although in the longer perspective, we would also like to be able to do something for minority language communities. We describe the basic implementation of Squirrel, and present preliminary results from trying it out. Finally we discuss the (lack of) Web resources in less prevalent languages, and how we imagine that applications like Squirrel could fit into a second or foreign languagelearning situation.

    Approximating phonotactic input in children’s linguistic environments from orthographic transcripts2017Inngår i: Proceedings of Interspeech 2017 / [ed] Francisco Lacerda, David House, Mattias Heldner, Joakim Gustafson, Sofia Strömbergsson, Marcin Włodarczak, The International Speech Communication Association (ISCA), 2017, s. 2214-2217Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Child-directed spoken data is the ideal source of support for claims about children’s linguistic environments. However, phonological transcriptions of child-directed speech are scarce,compared to sources like adult-directed speech or text data. Acquiring reliable descriptions of children’s phonological environments from more readily accessible sources would mean considerable savings of time and money. The first step towards this goal is to quantify the reliability of descriptions derived from such secondary sources. We investigate how phonological distributions vary across different modalities (spoken vs. written), and across the age of the intended audience (children vs. adults). Using a previously unseen collection of Swedish adult- and child-directed spoken and written data, we combine lexicon look-up and grapheme-to-phonemeconversion to approximate phonological characteristics. The analysis shows distributional differences across datasets both for single phonemes and for longer phoneme sequences. Some of these are predictably attributed to lexical and contextual characteristics of text vs. speech.The generated phonological transcriptions are remarkably reliable. The differences in phonological distributions between child-directed speech and secondary sources highlight a need for compensatory measures when relying on written data or onadult-directed spoken data, and/or for continued collection ofactual child-directed speech in research on children’s language environments.

    Proceedings of the Joint 6th Workshop on NLP for Computer Assisted Language Learning and 2nd Workshop on NLP for Research on Language Acquisition2017Konferanseproceedings (Fagfellevurdert)
    Abstract [en]

    For the second year in a row we brought two related themes of NLP for Computer-Assisted Language Learning and NLP for Language Acquisition together. The goal of organizing joint workshops is to provide a meeting place for researchers working on language learning issues including both empirical and experimental studies and NLP-based applications. The resulting volume covers a variety of topics from the two fields and - hopefully - showcases the challenges and achievements in the field.

    The seven papers in this volume cover native language identification in learner writings, using syntactic complexity development in language learner language to identify reading comprehension texts of appropriate level, exploring the potential of parallel corpora to predict mother-language specific problem areas for learners of another language, tools for learning languages - both well-resourced ones such as English as well as endangered or under-resourced ones such as Yakut and Võro, as well as exploring the potential of automatically identifying and correcting word-level errors in Swedish learner writing.

    Subjective ratings of age-of-acquisition: exploring issues of validity and rater reliability2019Inngår i: Journal of Child Language, ISSN 0305-0009, E-ISSN 1469-7602, Vol. 46, nr 2, s. 199-213Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study aimed to investigate concerns of validity and reliability in subjective ratings of age-of-acquisition (AoA), through exploring characteristics of the individual rater. An additional aim was to validate the obtained AoA ratings against two corpora – one of child speech and one of adult speech – specifically exploring whether words over-represented in the child-speech corpus are rated with lower AoA than words characteristic of the adult-speech corpus. The results show that less than one-third of participating informants’ ratings are valid and reliable. However, individuals with high familiarity with preschool-aged children provide more valid and reliable ratings, compared to individuals who do not work with or have children of their own. The results further show a significant, age-adjacent difference in rated AoA for words from the two different corpora, thus strengthening their validity. The study provides AoA data, of high specificity, for 100 child-specific and 100 adult-specific Swedish words.

    Modelling the Informativeness of Non-Verbal Cues in Parent–Child Interaction2017Inngår i: Proceedings of Interspeech 2017 / [ed] Francisco Lacerda, David House, Mattias Heldner, Joakim Gustafson, Sofia Strömbergsson, Marcin Włodarczak, The International Speech Communication Association (ISCA), 2017, s. 2203-2207Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Non-verbal cues from speakers, such as eye gaze and hand positions, play an important role in word learning. This is consistent with the notion that for meaning to be reconstructed, acoustic patterns need to be linked to time-synchronous patterns from at least one other modality. In previous studies of a multimodally annotated corpus of parent–child interaction, we have shown that parents interacting with infants at the early word-learning stage (7–9 months) display a large amount of time-synchronous patterns, but that this behaviour tails off with increasing age of the children. Furthermore, we have attempted to quantify the informativeness of the different nonverbal cues, that is, to what extent they actually help to discriminate between different possible referents, and how critical the timing of the cues is. The purpose of this paper is to generalise our earlier model by quantifying informativeness resulting from non-verbal cues occurring both before and after their associated verbal references.

    Longitudinal Studies of Variation Sets in Child-directed Speech2016Inngår i: The 54th Annual Meeting of the Association for Computational Linguistics: Proceedings of the 7th Workshop on Cognitive Aspects of Computational Language Learning, Stroudsburg, PA, USA: Association for Computational Linguistics, 2016, s. 44-52Konferansepaper (Fagfellevurdert)
    Abstract [en]

    One of the characteristics of child-directed speech is its high degree of repetitiousness. Sequences of repetitious utterances with a constant intention, variation sets, have been shown to be correlated with children’s language acquisition. To obtain a baseline for the occurrences of variation sets in Swedish, we annotate 18 parent–child dyads using a generalised definition according to which the varying form may pertain not just to the wording but also to prosody and/or non-verbal cues. To facilitate further empirical investigation, we introduce a surface algorithm for automatic extraction of variation sets which is easily replicable and language-independent. We evaluate the algorithm on the Swedish gold standard, and use it for extracting variation sets in Croatian, English and Russian. We show that the proportion of variation sets in child-directed speech decreases consistently as a function of children's age across Swedish, Croatian, English and Russian.

    Variationsmängder i barnriktat tal2013Inngår i: XIII Nordiska Barnspråkssymposiet - 2013 Stockholms universitet, Sverige, 8-9 november 2013, 2013Konferansepaper (Annet vitenskapelig)
    Abstract [sv]

    Barnriktat tal har en rad unika egenskaper som alla tycks härröra från föräldrarnas (omedvetna) önskan att som mycket som möjligt underlätta språkinlärningen för barnet. En av dessa egenskaper hos barnriktat tal är dess repetitivitet, till exempel i successiva yttranden som följande:

    Var kan Kucka vara då?

    Var är Kucka?

    Var är kaninen som heter Kucka?

    I det här papperet studerar vi den lokala repetitiviteten i barnriktat tal, som i litteraturen brukar kallas variationsmängder. Dessa är intressanta genom att de visar de ord och konstruktioner som föräldrarna vid varje tillfälle tycks koncentrera sig på att lära sina barn.

    Ett teoretiskt ramverk med bäring på detta är konstruktionsgrammatik, som antar att konstruktioner är inlärningsbara eftersom a) de utgör konventionaliserade form–betydelsepar som b) lärs in gradvis, alltifrån holofraser över schematiska uttryck ("item-based constructions", Tomasello 2003) till vuxenspråkets fullt abstraherbara konstruktioner. Genom att vi har longitudinella data så kan vi fånga i vad mån de successiva konstruktionerna anpassas enligt detta mönster allteftersom barnet blir äldre.

    Flera försök till formalisering av begreppet variationsmängd har föreslagits, till exempel Küntay och Slobin (1996), Brodsky et al. (2007) och Onnis et al. (2008). Vanliga krav på en variationsmängd är att den a) utgör successiva yttranden med upp till två mellanliggande yttranden; b) att minst två av de ingående orden upprepas; och c) att yttrandenas intention är konstant. Vi experimenterar med olika värden på a) och använder stället för b) en strängmatchningsmetod som även tar hänsyn till yttrandelängden.

    I papperet redovisar vi utfallet av konstruktionstyper baserat på data från en longitudinell korpus med barnriktat tal för tretton barn i åldrar mellan 3 och 33 månader, fördelade på 58 sessioner.
