   Sammanfattning : This compilation thesis engages with practices that in some way place stakes in the social existence of Övdalsk (also älvdalska, Elfdalian, Övdalian), a marginal form of Scandinavian used mainly in Sweden’s Älvdalen municipality.

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

   Författare :David Alfter; Göteborgs universitet; []
   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.

   Sammanfattning : Condition Monitoring (CM) is widely used in industry to meet sustainability, safety, and equipment efficiency requirements. Intelligent Fault Diagnosis (IFD) research focuses on automating CM data analysis tasks, to detect and prevent machine faults, and provide decision support. LÄS MER

5. 4. A novel approach to text classification

   Författare :Niklas Zechner; Johanna Björklund; Efstathios Stamatatos; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Text classification; natural language processing; automata; Computer Science; datalogi;

   Sammanfattning : This thesis explores the foundations of text classification, using both empirical and deductive methods, with a focus on author identification and syntactic methods. We strive for a thorough theoretical understanding of what affects the effectiveness of classification in general. LÄS MER

7. 5. Language policy from below : Bilingual education and heterogeneity in post-apartheid South Africa

   Författare :Peter Plüddemann; Christopher Stroud; Nancy Hornberger; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; bilingual education; mother tongue; language policy from below; heterogeneity; multilingualism; language ideology; South Africa; tvåspråkighetsforskning; Bilingualism;

   Sammanfattning : The present thesis on bilingual education, with its foci on linguistic heterogeneity and language policy 'from below', covers the first 15 years in the officially multilingual new South Africa. The post-apartheid era has seen South Africa's pro-multilingual Constitution and the language-in-education policy for schools being sidelined in favour of an English-oriented mindset. LÄS MER
