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

    University dissertation from Stockholm, Sweden : Department of Computer and Systems Sciences, Stockholm University

    Author : Aron Henriksson; Stockholms universitet.; [2013]
    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.

  2. 2. Temporal and co-varying clause combining in Austronesian languages Semantics, morpho-syntax and distributional patterns

    University dissertation from Stockholm : Department of Linguistics, Stockholm University

    Author : Niklas Jonsson; Stockholms universitet.; [2012]
    Keywords : HUMANIORA; HUMANITIES; Austronesian; clause combining; clause linkage; interclausal relations; Austronesiska; satsrelationer; Linguistics; lingvistik;

    Abstract : This study investigates combined clause constructions for ten distinct semantic relations in a cross-section of Austronesian languages. The relations are of a temporal or co-varying nature, the former commonly expressed in English by such markers as when, then, until, etc. and the latter by if, so, because, etc. READ MORE

  3. 3. Extracting Clinical Findings from Swedish Health Record Text

    University dissertation from Stockholm University : Department of Computer and Systems Sciences, Stockholm University

    Author : Maria Skeppstedt; Stockholms universitet.; [2014]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Named entity recognition; Corpora development; Clinical text processing; Distributional semantics; Random indexing; Vocabulary expansion; Assertion classification; Clinical text mining; Electronic health records; Swedish; data- och systemvetenskap; Computer and Systems Sciences;

    Abstract : Information contained in the free text of health records is useful for the immediate care of patients as well as for medical knowledge creation. Advances in clinical language processing have made it possible to automatically extract this information, but most research has, until recently, been conducted on clinical text written in English.

  4. 4. Cross-language Ontology Learning Incorporating and Exploiting Cross-language Data in the Ontology Learning Process

    University dissertation from Stockholm : Institutionen för lingvistik

    Author : Hans Hjelm; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ontologies; Ontology learning; Distributional semantics; Knowledge acquisition; Text mining; HUMANITIES and RELIGION Languages and linguistics Linguistic subjects Computational linguistics; HUMANIORA och RELIGIONSVETENSKAP Språkvetenskap Lingvistikämnen Datorlingvistik; datorlingvistik; Computational Linguistics;

    Abstract : An ontology is a knowledge-representation structure, where words, terms or concepts are defined by their mutual hierarchical relations. Ontologies are becoming ever more prevalent in the world of natural language processing, where we currently see a tendency towards using semantics for solving a variety of tasks, particularly tasks related to information access.

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

    University dissertation from Gothenburg : Department of Philosophy, Linguistics and Theory of Science. The Centre for Linguistic Theory and Studies in Probability (CLASP), University of Gothenburg

    Author : Mehdi Ghanimifard; Göteborgs universitet.; Gothenburg University.; [2020]
    Keywords : Computational linguistics; Language grounding; Spatial language; Distributional semantics; Computer vision; Language modelling; Vision and language; Neural language model; Grounded language model;

    Abstract : 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. READ MORE
