  1. 1. Why the pond is not outside the frog? Grounding in contextual representations by neural language models

    Författare :Mehdi Ghanimifard; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational linguistics; Language grounding; Spatial language; Distributional semantics; Computer vision; Language modelling; Vision and language; Neural language model; Grounded language model;

    Sammanfattning : In this thesis, to build a multi-modal system for language generation and understanding, we study grounded neural language models. Literature in psychology informs us that spatial cognition involves different aspects of knowledge that include visual perception and human interaction with the world. LÄS MER

  2. 2. Error Handling in Spoken Dialogue Systems : Managing Uncertainty, Grounding and Miscommunication

    Författare :Gabriel Skantze; Rolf Carlson; Alexander Rudnicky; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; speech communications; linguistics; Language technology; Språkteknologi;

    Sammanfattning : Due to the large variability in the speech signal, the speech recognition process constitutes the major source of errors in most spoken dialogue systems. A spoken dialogue system can never know for certain what the user is saying, it can only make hypotheses. LÄS MER

  3. 3. CALL of the Wild : Using language technology in the second language classroom

    Författare :Petter Karlström; Robert Ramberg; Teresa Cerratto-Pargman; Philip Hubbard; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Computer Assisted Language Learning; Human-Computer Interaction; Interaction Design; Language Technology; Sociocultural Theory; Computer and systems science; Data- och systemvetenskap; Man-Machine-Interaction MMI ; människa-maskin-interaktion mmi ; människa-maskin-interaktion MMI ;

    Sammanfattning : Technology that analyzes written human language displays compelling possibilities for computer assisted language learning (CALL). Applications may be designed to examine second language students’ free text production in order to suggest improvements, draw attention to selected linguistic elements, provide examples from native language use, etc. LÄS MER

  4. 4. Knowledge based perceptual anchoring : grounding percepts to concepts in cognitive robots

    Författare :Marios Daoutis; Silvia Coradeschi; Amy Loutfi; Angelo Cangelosi; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; anchoring; knowledge representation; cognitive perception; symbol grounding; common-sense information; Computer and Systems Science; Datavetenskap;

    Sammanfattning : A successful articial cognitive agent needs to integrate its perception of the environment with reasoning and actuation. A key aspect of this integration is the perceptual-symbolic correspondence, which intends to give meaning to the concepts the agent refers to { known as Anchoring. However, perceptual representations alone (e.g. LÄS MER

  5. 5. Teaching mobile robots to use spatial words

    Författare :Simon Dobnik; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; situated interaction; spatial descriptions; language and perception; perceptual grounding; dialogue; natural language semantics; machine learning;

    Sammanfattning : The meaning of spatial words can only be evaluated by establishing a reference to the properties of the environment in which the word is used. For example, in order to evaluate what is to the left of something or how fast is fast in a given context, we need to evaluate properties such as the position of objects in the scene, their typical function and behaviour, the size of the scene and the perspective from which the scene is viewed.
