  1. 6. Representations of discourse : cognitive and computational aspects

    Författare :Nils Dahlbäck; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : This work is concerned with empirical studies of cognitive and computational aspects of discourse representations. A more specific aim is to contribute to the development of natural language interfaces for interaction with computers, especially the development of representations making possible a continuous interactive dialogue between user and system.

  3. 7. Indoor Navigation for Mobile Robots : Control and Representations

    Författare :Philipp Althaus; KTH; []
    Nyckelord :mobile robots; robot navigation; indoor navigation; behaviour based robotics; hybrid deliberative systems; dynamical systems approach; topological maps; symbol anchoring; autonomous mapping; human-robot interaction;

    Sammanfattning : This thesis deals with various aspects of indoor navigationfor mobile robots. For a system that moves around in ahousehold or office environment,two major problems must betackled. First, an appropriate control scheme has to bedesigned in order to navigate the platform. Second, the form ofrepresentations of the environment must be chosen. LÄS MER

  4. 8. Didaktisk design med digitala resurser : En studie av kunskapsrepresentationer i en digitaliserad skola

    Författare :Anna Åkerfeldt; Anna-Lena Kempe; Staffan Selander; Sten Ludvigsen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; didactic design; designs for learning; knowledge; representations; digital resources; cultures of recognition; multimodality; didaktiks design; design för lärande; kunskap; representationer; digitala resurser; erkännandekulturer; multimodalitet; Didactics; didaktik;

    Sammanfattning : In digital-classroom practices, pupils design their learning processes in collaboration with their peers, employing different semiotic resources when representing signs of learning in a constant flow. There still remain differences, however, between learning practices and the way pupils are formally tested. LÄS MER

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

    Författare :Luis Nieto Piña; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 10. Classification of simple transitive 2-representations

    Författare :Jakob Zimmermann; Volodymyr Mazorchuk; Joseph Chuang; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 2-representation theory; 2-categories; Soergel bimodules; projective functors; cell 2-representations; simple transitive 2-representations;

    Sammanfattning : The representation theory of finitary 2-categories is a generalization of the classical representation theory of finite dimensional associative algebras. A key notion in classical representation theory is the notion of simple modules as those are in some sense the building blocks of all modules. LÄS MER
