  1. 1. With or without context Automatic text categorization using semantic kernels

    University dissertation from Högskolan i Borås

    Author : Johan Eklund; Högskolan i Borås.; [2016]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; automatic text categorization; subject classification; machine learning; computational linguistics; support vector machines; semantic kernels; term weighting; divergence from randomness; Library and Information Science; Biblioteks- och informationsvetenskap;

    Abstract : In this thesis text categorization is investigated in four dimensions of analysis: theoretically as well as empirically, and as a manual as well as a machine-based process. In the first four chapters we look at the theoretical foundation of subject classification of text documents, with a certain focus on classification as a procedure for organizing documents in libraries.

  3. 3. Generalized Hebbian Algorithm for Dimensionality Reduction in Natural Language Processing

    University dissertation from Institutionen för datavetenskap

    Author : Genevieve Gorrell; Linköpings universitet.; Linköpings universitet.; [2006]
