  1. 26. 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

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

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

    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

  4. 28. Modularization of the Learning Architecture : Supporting Learning Theories by Learning Technologies

    Författare :Fredrik Paulsson; Yngve Sundblad; Miguel Angel-Cecilia; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Technology Enhanced Learning; e-learning; Semantic Web; Service Orientation; Learning Object; Virtual Learning Environment; Computer science; Datavetenskap;

    Sammanfattning : This thesis explores the role of modularity for achieving a better adaptation of learning technology to pedagogical requirements. In order to examine the interrelations that occur between pedagogy and computer science, a theoretical framework rooted in both fields is applied. LÄS MER

  5. 29. On Fundamental Elements of Visual Navigation Systems

    Författare :Abujawad Rafid Siddiqui; J. Rafid Siddiqui; Sweden Karlskrona Blekinge Tekniska Högskola Institutionen för kommunikationssystem; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot navigation; localization; visual mapping; scene understanding; semantic mapping;

    Sammanfattning : Visual navigation is a ubiquitous yet complex task which is performed by many species for the purpose of survival. Although visual navigation is actively being studied within the robotics community, the determination of elemental constituents of a robust visual navigation system remains a challenge. LÄS MER

  7. 30. Adaptable metadata creation for the Web of Data

    Författare :Fredrik Enoksson; Olle Bälter; Ambjörn Naeve; Jane Greenberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metadata; Metadata Editing; RDF; Web of Data; Semantic Web; Linked Data; End User Development; Media Technology; Medieteknik;

    Sammanfattning : One approach to manage collections is to create data about the things in it. This descriptive data is called metadata, and this term is in this thesis used as a collective noun, i.e no plural form exists. A library is a typical example of an organization that uses metadata, to manage a collection of books. LÄS MER
