  1. 1. Antonyms in Context : A Corpus-Based Semantic Analysis of Swedish Descriptive Adjectives

    Författare :Caroline Willners; Allmän språkvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; Nordiska språk språk och litteratur ; Scandinavian languages and literature; WordNet; semantic frameword; semantic network; sentential co-occurrence; semantic range; adjectives; antnoymy; lexical semantics; corpus-based methods; Lexicology; Lexikologi; Grammar; semantics; semiotics; syntax; Grammatik; semantik; semiotik;

    Sammanfattning : How are antonym relations acquired? What types of lexical information can be extracted from corpora and how? How can this information be encoded in a lexicon? The work in this book was developed within the framework of WordNet. A further elaborated lexical model is suggested, as well as methods for implementing it. LÄS MER

  3. 2. Data-Efficient Learning of Semantic Segmentation

    Författare :David Nilsson; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; semantic segmentation; embodied learning; active learning; semantic video segmentation; computer vision; deep learning;

    Sammanfattning : Semantic segmentation is a fundamental problem in visual perception with a wide range of applications ranging from robotics to autonomous vehicles, and recent approaches based on deep learning have achieved excellent performance. However, to train such systems there is in general a need for very large datasets of annotated images. LÄS MER

  4. 3. Ensembles of Semantic Spaces : On Combining Models of Distributional Semantics with Applications in Healthcare

    Författare :Aron Henriksson; Hercules Dalianis; Martin Duneld; Nigel Collier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; natural language processing; machine learning; distributional semantics; ensemble learning; semantic space ensembles; medical informatics; electronic health records; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Distributional semantics allows models of linguistic meaning to be derived from observations of language use in large amounts of text. By modeling the meaning of words in semantic (vector) space on the basis of co-occurrence information, distributional semantics permits a quantitative interpretation of (relative) word meaning in an unsupervised setting, i.

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

    Författare :Aron Henriksson; Hercules Dalianis; Martin Duneld; Jussi Karlgren; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Ditransitives in Swedish : A Usage-Based Study of the Double Object Construction and Semantically Equivalent Prepositional Object Constructions 1800–2016

    Författare :Fredrik Valdeson; Cecilia Falk; Jan Svanlund; Catrin Norrby; Elena Smirnova; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; ditransitives; double object construction; dative alternation; Late Modern Swedish; construction grammar; usage-based; lexical richness; language change; semantic change; semantic maps; taxonomic networks; horizontal links; Scandinavian Languages; nordiska språk;

    Sammanfattning : This thesis examines the use of the Swedish double object construction (the DOC) and compares this with the use of three semantically equivalent prepositional object constructions (POCs): the till-POC, the åt-POC and the för-POC. The thesis has a diachronic perspective, investigating changes in the use of these four constructions between 1800 and 2016. LÄS MER
