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

   Författare :Johan Eklund; Högskolan i Borås; []
   Nyckelord :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;

   Sammanfattning : 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.
