  1. 11. Clustering in Swedish : The Impact of some Properties of the Swedish Language on Document Clustering and an Evaluation Method

    Författare :Magnus Rosell; Viggo Kann; Björn Levin; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Document Clustering; Language technology; Språkteknologi;

    Sammanfattning : Text clustering divides a set of texts into groups, so that texts within each group are similar in content. It may be used to uncover the structure and content of unknown text sets as well as to give new perspectives on known ones. LÄS MER

  2. 12. Unsupervised Learning of Morphology: Survey, Model, Algorithm and Experiments

    Författare :Harald Hammarström; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis contains work on a specific problem in field of Language Technology. The problem can be described as follows: "Can a computer extract a description of word conjugation in a natural language using only written text in the language?" The problem is often referred to as Unsupervised Learning of Morphology (ULM) and has a wide variety of Language Technology applications, including Machine Translation, Document Categorization and I nformation Retrieval.

  3. 13. Graph Algorithms for Large-Scale and Dynamic Natural Language Processing

    Författare :Kambiz Ghoorchian; Magnus Boman; Magnus Sahlgren; Sumithra Velupillai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural Language Processing; Lexical Disambiguation; Topic Modeling; Representation Learning; Graph Partitioning; Distributed Algorithms; Dimensionality Reduction; Random Indexing; ;

    Sammanfattning : In Natural Language Processing, researchers design and develop algorithms to enable machines to understand and analyze human language. These algorithms benefit multiple downstream applications including sentiment analysis, automatic translation, automatic question answering, and text summarization. LÄS MER

  4. 14. Bounded Rationality and Exemplar Models

    Författare :Magnus Persson; Peter Juslin; Nick Chater; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; PROBEX; Lazy Algorithm; Probabilistic Inference; Decision Making; Bounded Rationality; Ecological Rationality; Take The Best; exemplar models; correspondence; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Bounded rationality is the study of how human cognition with limited capacity is adapted to handle the complex information structures in the environment. This thesis argues that in order to understand the bounded rationality of decision processes, it is necessary to develop decision theories that are computational process models based upon basic cognitive and perceptual mechanisms.
