    Sammanfattning : Given the explosive growth of web pages on the Internet in the last decade, automatic classification and categorization of web pages have grown into an important task. This thesis sets out to evaluate whether or not methods for text and image analysis, which had not been evaluated for web page classification, could improve on the state-of-the-art methods in web page classification.

  4. 4. Concept development to extract sodium sulfate from an aqueous solution

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :André Selander; [2021]
    Nyckelord :biorefinery; aqueous solution; sodium sulfate; crystallisation; crystallization; kraft process;

    Sammanfattning : Now when the interest is increasing to reach a sustainable infrastructure, one possibility SCA is experimenting with is the possibility to produce renewable hydrocarbons from black liquor which can be extracted from a Kraft process. However, when extracting the black liquor, a lot of sodium-based compounds are removed from the recovery process and when hydrocarbons are produced in SCA’s biorefinery, these compounds are caught in an aqueous solution.

  5. 5. Extracting Transaction Information from Financial Press Releases

    Master-uppsats, Linköpings universitet/Artificiell intelligens och integrerade datorsystem

    Författare :Agaton Sjöberg; [2021]
    Nyckelord :Natural Language Processing; Information Extraction; Named Entity Recognition; Relation Extraction; Latent Structure Refinement; Financial Press Release; Insider Transaction;

    Sammanfattning : The use cases of Information Extraction (IE) are more or less endless, often consisting of a combination of Named Entity Recognition (NER) and Relation Extraction (RE). One use case of IE is the extraction of transaction information from Norwegian insider transaction Press Releases (PRs), where a transaction consists of at most four entities: the name of the owner performing the transaction, the number of shares transferred, the transaction date, and the price of the shares bought or sold.
