  2. 1. Exploring Latent Semantic Vector Models Enriched With N-grams

    Author : Leif Grönqvist; Joakim Nivre; Jussi Karlgren; Helena Ahonen-Myka; Växjö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

    Abstract : Denna avhandling behandlar en sorts vektorrumsmodell som jag kallar ”Latent Semantic Vector Model”, eller LSVM, framtagen med tekniken ”Latent Semantic Indexing”. En LSVM har många användningsområden men jag har i första hand tittat på en direkt tillämpning: dokumentsökning. READ MORE

    Author : Martin Westberg; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phylogeny; ITS rDNA; Systematic botany; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; distribution; anatomy; Candelariaceae; Candelariella; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Abstract : The lichen genus Candelariella comprises crustose to small squamulose members of the family Candelariaceae. The genus currently includes c. 50 species world-wide but few studies have treated the taxonomy within this group. In the present thesis the taxonomy of the genus in western North America is treated.

    Abstract : This thesis is divided into two parts. The first part describes the syntheses of the Lewis b blood group antigen hexasaccharide and parts thereof. The Leb blood group antigen is one of the binding epitopes for the Helicobacter pylori bacteria in the human stomach. READ MORE

  7. 5. Semantic Spaces of Clinical Text : Leveraging Distributional Semantics for Natural Language Processing of Electronic Health Records

    Author : Aron Henriksson; Hercules Dalianis; Martin Duneld; Jussi Karlgren; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; distributional semantics; random indexing; semantic space; electronic health records; clinical text; synonyms; diagnosis codes; adverse drug reactions; Computer and Systems Sciences; data- och systemvetenskap; IT for health; IT för hälsa; datorlingvistik; Computational Linguistics; datalogi; Computer Science;

    Abstract : The large amounts of clinical data generated by electronic health record systems are an underutilized resource, which, if tapped, has enormous potential to improve health care. Since the majority of this data is in the form of unstructured text, which is challenging to analyze computationally, there is a need for sophisticated clinical language processing methods. READ MORE
