  2. 21. Word Vector Representations using Shallow Neural Networks

    Author : Oluwatosin Adewumi; Marcus Liwicki; Marco Kuhlmann; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Word vectors; NLP; Neural networks; Embeddings; Maskininlärning; Machine Learning;

    Abstract : This work highlights some important factors for consideration when developing word vector representations and data-driven conversational systems. The neural network methods for creating word embeddings have gained more prominence than their older, count-based counterparts. READ MORE

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

    Author : Wafia Adouane; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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.

  5. 23. 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.

  6. 24. Scaffolding foreign language learners’ reading strategies using tablet computers at two secondary schools in Denmark

    Author : Nathalie Auer; UK University of Leicester; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mobile learning; reading strategies; digital reading; metacognition apply to reading;

    Abstract : The use of mobile devices for learning has led to an increased number of textbooks and reading materials being published in digital format. Specific digital literacies are required to take advantage of these digital texts, and students need to acquire these literacies if they are to read and learn efficiently. READ MORE

  7. 25. Adaptive Robot Presenters : Modelling Grounding in Multimodal Interaction

    Author : Agnes Axelsson; Gabriel Skantze; Johan Boye; Elisabeth André; KTH; []

    Abstract : This thesis addresses the topic of grounding in human-robot interaction, that is, the process by which the human and robot can ensure mutual understanding. To explore this topic, the scenario of a robot holding a presentation to a human audience is used, where the robot has to process multimodal feedback from the human in order to adapt the presentation to the human's level of understanding.
