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

   Author : David Alfter; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; natural language processing; lexical complexity; CEFR; second language learning; machine learning; crowdsourcing;

   Abstract : 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. 2. Age and Constraints on Language Learning : First Language Retention and Second Language Acquisition in International Adoptees

   Author : Gunnar Norrman; Emanuel Bylund Spångberg; Guillaume Thierry; Janet Werker; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bilingualism; critical period; electroencephalography; event-related potentials; first language retention; international adoption; phonology; second language acquisition; Bilingualism; tvåspråkighet;

   Abstract : This thesis investigates the influence of age of acquisition on the long-term second language development of international adoptees. Because age of acquisition typically coincides with the onset of bilingualism, the study of maturational age effects in second language acquisition has been empirically and conceptually entangled with changes in language input and use.

5. 3. Rapid neural processing of grammatical tone in second language learners

   Author : Sabine Gosselke Berthelsen; Allmän språkvetenskap; []
   Keywords : HUMANIORA; HUMANITIES; grammatical tone; phonology; phonetics; word accent; morphology; inflection; grammar; EEG; ERP; processing; violations; ELAN; LAN; P600; second language acquisition; SLA; beginner learners; transfer; German; Swedish;

   Abstract : The present dissertation investigates how beginner learners process grammatical tone in a second language and whether their processing is influenced by phonological transfer. Paper I focuses on the acquisition of Swedish grammatical tone by beginner learners from a non-tonal language, German. READ MORE

6. 4. The language learning infant: Effects of speech input, vocal output, and feedback

   Author : Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; human; language; language acquisition; perception; production; humanoid; development; model; embodied system; speech signal processing; vocal tract morphology; acoustic; speech input; information processing; scaling; interaction; growth; infant; imitation; feedback; perceptual salience; modeling; Phonetics; Fonetik; Phonetics; fonetik;

   Abstract : This thesis studies the characteristics of the acoustic signal in speech, especially in speech directed to infants and in infant vocal development, to gain insight on essential aspects of speech processing, speech production and communicative interaction in early language acquisition. Three sets of experimental studies are presented in this thesis. READ MORE

7. 5. Methods and Tools for Automating Language Engineering

   Author : Grégoire Détrez; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Natural language processing; Language Engineering; Morphology; Lexicon; Complexity;

   Abstract : Language-processing software is becoming increasingly present in our society. Making such tools available to the greater number is not just a question of access to technology but also a question of language as they need to be adapted, or localized, to each linguistic community.
