  1. 1. Exploring natural language processing for single-word and multi-word lexical complexity from a second language learner perspective

    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; natural language processing; lexical complexity; CEFR; second language learning; machine learning; crowdsourcing;

    Sammanfattning : In this thesis, we investigate how natural language processing (NLP) tools and techniques can be applied to vocabulary aimed at second language learners of Swedish in order to classify vocabulary items into different proficiency levels suitable for learners of different levels. In the first part, we use feature-engineering to represent words as vectors and feed these vectors into machine learning algorithms in order to (1) learn CEFR labels from the input data and (2) predict the CEFR level of unseen words.

  4. 3. Investigating and Validating Spoken Interactional Competence: Rater Perspectives on a Swedish National Test of English

    Författare :Linda Borger; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; interactional competence; Swedish national test of English; paired speaking test; Common European Framework of Reference for Languages CEFR ; socio-cognitive validation framework;

    Sammanfattning : This thesis aims to explore different aspects of validity evidence from the raters’ perspective in relation to a paired speaking test, part of a high-stakes national test of English as a Foreign Language (EFL) in the Swedish upper secondary school. Three empirical studies were undertaken with the purpose of highlighting (1) the scoring process, (2) the construct underlying the test format, and (3) the setting and test administration. LÄS MER

  7. 5. Snakes and Ladders : Developmental Aspects of Lexical-Conceptual Relationships in the Multilingual Mental Lexicon

    Författare :Lari-Valtteri Suhonen; Språkinlärning; []

    Sammanfattning : One phenomenon causing issues for language learners in the form of cross-linguistic influence (CLI) is translation ambiguity (Eddington & Tokowicz, 2013). Translation ambiguity refers to a situation where word meanings are different in a speaker’s languages. LÄS MER
