    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Adam Österberg; [2022]
    Keywords : Natural Language Processing; Wikipedia; Topic Modeling; Labeling; Språkteknologi; Wikipedia; Temamodellering; Märkning;

    Abstract : Labeling is the process of giving a set of data a descriptive name. This thesis dealt with documents with no additional information and aimed at clustering them using topic modeling and labeling them using Wikipedia as a second source. Labeling documents is a new field with many potential solutions. READ MORE

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Simon Leijon; [2022]
    Keywords : ;

    Abstract : With the vast amount of natural language data that is widely availabletoday there is an increased demand in being able to process, analyzeand explore large corpora of texts efficiently. One method to explorethese corpora is by creating a recommender system based on the texts.The most common recommender system to this end is what is knownas Google. READ MORE

  5. 14. Investigating Search Algorithms for Shorter Documents : A study on how to search for titles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lara Rostami; [2022]

    Abstract : The objective of this thesis was to explore whether there are alternatives to the established search ranking algorithm Best Matching 25 (BM25) when searching for shorter documents, in particular for the search of titles. Five search engines were compared to BM25, three of them being variants of the BM25 algorithm and the other two being based on a binary independence model that does not take term frequency or length normalisation into account.
