    • An automated solution to facilitate sustainable DSM in the mining environment 

      Steyl, Jacob Petrus (North-West University, 2008)
      South Africa is experiencing a serious electricity supply problem. This problem is expected to persist until at least 2012. During the winter of 2006 load shedding and electricity supply-cuts started occurring in the Western ...
    • Automatic alignment of audiobooks in Afrikaans 

      Carel J. van Heerden; Febe de Wet; Marelie H. Davel (Pattern recognition association of South Africa (PRASA), 2012)
      This paper reports on the automatic alignment of audiobooks in Afrikaans. An existing Afrikaans pronunciation dictionary and corpus of Afrikaans speech data are used to generate baseline acoustic models. The baseline system ...
    • Automatic genre classification of English students' argumentative essays using support vector machines 

      Raaff, Sabrina (North-West University, 2007)
      Automatic text classification refers to the classification of texts according to topic. Similar to text classification is the automatic classification of texts based on stylistic aspect of texts, such as automatic genre ...
    • Automatic infarct planimetry by means of swarm-based clustering 

      Van Vuuren, Pieter A.; Van Vuuren, Derick (PRASA, 2014)
      Infarct planimetry is an important tool in cardiology research. At present this technique entails that infarct size is manually determined from scanned images of prepared heart sections. Existing attempts at automating ...
    • Automatic lemmatisation for Afrikaans 

      Groenewald, Hendrik Johannes (North-West University, 2006)
      A lemmatiser is an important component of various human language technology applicalions for any language. At present, a rule-based le~nmatiserf or Afrikaans already exists, but this lermrlatiser produces disappoinringly ...
    • Automatic Recognition of Code-Switched Speech in Sepedi 

      Modipa, Thipe Isaaih (2016)
      Code switching (CS) is a natural phenomenon that is often observed in multilingual speakers. These speakers use words, phrases or sentences from foreign languages and embed them in sentences in the primary language. ...
