  1. 16. The Virtual Language Teacher : Models and applications for language learning using embodied conversational agents

    Författare :Preben Wik; Björn Granström; Olov Engwall; Valerie Hazan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Language learning; embodied conversational agents; speech technology; computer assisted language learning; computer assisted pronunciation training; Information technology; Informationsteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : This thesis presents a framework for computer assisted language learning using a virtual language teacher. It is an attempt at creating, not only a new type of language learning software, but also a server-based application that collects large amounts of speech material for future research purposes.

  3. 17. The dynamics of second language learning : a longitudinal and qualitative study of an adult's learning of Swedish

    Författare :Nils Granberg; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; second language learning; second language acquisition; individual differences; attitude; motivation; learning strategies; communication strategies; identity; liminality; case study; Grounded Theory; hermeneutic; qualitative; holistic; longitudinal; Swedish;

    Sammanfattning : An often discussed issue in the field of second language learning is the influence and importance of individual differences, IDs, such as motivation, personality, previous learning experiences and learning strategies. It has been claimed that IDs form a complex system in the learner, but little consensus has been reached as regards definitions of constructs or their relative importance. LÄS MER

  4. 18. English Hemspråk : Language in Interaction in English Mother Tongue Instruction in Sweden

    Författare :Kirsten Stoewer; Jakob Cromdal; Nigel John Musk; Wei Li; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mother tongue instruction; English as a heritage language; conversation analysis; classroom interaction; bilingual interaction; vocabulary teaching; language alternation; Modersmålsundervisning; engelska som modersmål; samtalsanalys; klassrumsinteraktion; tvåspråkig interaktion; ordförråd i undervisning; kodväxling;

    Sammanfattning : The thesis investigates teacher-student interaction in English mother tongue instruction (MTI), offered within mainstream education to English heritage language students in Sweden. In particular, it examines the type of language work that was in focus during the lessons and the ways teacher and students engaged in the language work in situ. LÄS MER

  5. 19. Natural Language Processing for Low-resourced Code-switched Colloquial Languages – The Case of Algerian Language

    Författare :Wafia Adouane; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural language processing; Deep neural networks; Low-resourced language; Colloquial language; Code-switch; Dialectal Arabic; User-generated data; Non-standardised orthography; Algerian language;

    Sammanfattning : In this thesis we explore to what extent deep neural networks (DNNs), trained end-to-end, can be used to perform natural language processing tasks for code-switched colloquial languages lacking both large automated data and processing tools, for instance tokenisers, morpho-syntactic and semantic parsers, etc. We opt for an end-to-end learning approach because this kind of data is hard to control due to its high orthographic and linguistic variability.

  7. 20. Word Sense Embedded in Geometric Spaces - From Induction to Applications using Machine Learning

    Författare :Mikael Kågebäck; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; word sense induction; word sense disambiguation; word embeddings; extractive summarisation; neural networks; deep learning; natural language procsessing; reinforcement learning;

    Sammanfattning : Words are not detached individuals but part of a beautiful interconnected web of related concepts, and to capture the full complexity of this web they need to be represented in a way that encapsulates all the semantic and syntactic facets of the language. Further, to enable computational processing they need to be expressed in a consistent manner so that similar properties are encoded in a similar way. LÄS MER
