  1. 1. On the Clebsch-Gordan problem for quiver representations

    Author : Martin Herschend; Ernst Dieterich; Alex Martsinkovsky; Karin Erdmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Algebra and geometry; quiver; quiver representation; tensor product; Clebsch-Gordan problem; representation ring; bialgebra; Galois covering; Algebra och geometri;

    Abstract : On the category of representations of a given quiver we define a tensor product point-wise and arrow-wise. The corresponding Clebsch-Gordan problem of how the tensor product of indecomposable representations decomposes into a direct sum of indecomposable representations is the topic of this thesis.

  2. 2. Splitting rocks: Learning word sense representations from corpora and lexica

    Author : Luis Nieto Piña; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; language technology; natural language processing; distributional models; semantic representations; distributed representations; word senses; embeddings; word sense disambiguation; linguistic resources; corpus; lexicon; machine learning; neural networks;

    Abstract : The representation of written language semantics is a central problem of language technology and a crucial component of many natural language processing applications, from part-of-speech tagging to text summarization. These representations of linguistic units, such as words or sentences, allow computer applications that work with language to process and manipulate the meaning of text. READ MORE

  3. 3. Ageism in the Media : Online Representations of Older People

    Author : Wenqian Xu; Annika Taghizadeh Larsson; Lars-Christer Hydén; Andreas Motel; Alexander Peine; Linköpings universitet; []

    Abstract : Ageism is a social problem that has harmful effects on the wellbeing of older people and needs to be tackled. It is pervasive and evident in the media (e.g., films, television, print and social media). READ MORE

  4. 4. The semiotic function : studies in children's representations

    Author : Maare Tamm; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Piaget; Semiotic function; Mental representation Figurative; Operative; Representation media;

    Abstract : The main purpose of this thesis was to explore if there existed one single underlying semiotic function for representation. The problem was examined from both a theoretical and an empirical point of view. READ MORE
