  1. 1. Using Language Technology to Mediate Medical Information on Health Portals : User Studies and Experiments

    Författare :Andrea Andrenucci; Hercules Dalianis; Sumithra Velupillai; Diego Mollá Aliod; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; language technology; health portals; cross-language information retrieval; knowledge patterns; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : The World Wide Web has revolutionized our lifestyle, our economies and services within health care. Health care services are no longer provided only at specialist centers and at scheduled hours, but also through online tools that give health care consumers access to medical information, health records, medical counselling and peer support.

  3. 2. Resource Lean and Portable Automatic Text Summarization

    Författare :Martin Hassel; Hercules Dalianis; Viggo Kann; Kerstin Severinson Eklundh; Horacio Saggion; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; holsum; language independent; holistic; summarization; lexical semantics; co-occurrence statistics; word space model; bag-of-words; bag-of-concepts; random indexing; swesum; news corpus; extract corpus; Computer science; Datalogi;

    Sammanfattning : Today, with digitally stored information available in abundance, even for many minor languages, this information must by some means be filtered and extracted in order to avoid drowning in it. Automatic summarization is one such technique, where a computer summarizes a longer text to a shorter non-rendundant form. 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. Extracting Clinical Findings from Swedish Health Record Text

    Författare :Maria Skeppstedt; Hercules Dalianis; Gunnar Nilsson; Maria Kvist; Tapio Salakoski; Stockholms universitet; []
    Nyckelord :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; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : 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.
