  3. 22. Generalized Hebbian Algorithm for Dimensionality Reduction in Natural Language Processing

    Författare :Genevieve Gorrell; Arne Jönsson; Robin Cooper; Alexander Rudnicky; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Generalized Hebbian Algorithm; Language Modelling; Singular Value Decomposition; Eigen Decomposition; Latent Semantic Analysis; Vector Space Models; Computational linguistics; Datorlingvistik;

    Sammanfattning : The current surge of interest in search and comparison tasks in natural language processing has brought with it a focus on vector space approaches and vector space dimensionality reduction techniques. Presenting data as points in hyperspace provides opportunities to use a variety of welldeveloped tools pertinent to this representation. LÄS MER

  4. 23. Computer-Assisted Language Learning with Grammars. A Case Study on Latin Learning

    Författare :Herbert Lange; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Compuer-Assisted Language Learning; Controlled Natural Language; Latin;

    Sammanfattning : Learning new languages has a high relevance in today’s society with a globalized economy and the freedom to move abroad for work, study or other reasons. In this context new methods to teach and learn languages with the help of modern technology are becoming more relevant besides traditional language classes. LÄS MER

  5. 24. 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.

  7. 25. 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
