CID3: an extension of ID3 for attributes with ordered domains

Cloete, I; Theron, H (South African Institute of Computer Scientists and Information Technologists, 1991)

Quinlan's ID3 is a popular and efficient algorithm for inducing decision trees from concept examples, where the examples are presented as vectors of attribute-value pairs. If some attributes have integer or real domains ...
Discriminators for authorship attribution

Paijmans, H (South African Computer Society (SAICSIT), 1999)

This paper describes some experiments with the automated attribution of authorship. Lexical cohesion in combination with machine learning techniques are used as a method to compare texts of different authors. A methodology ...
Integrating similarity-based and explanation-based learning

Oosthuizen, GD; Avenant, C (South African Institute of Computer Scientists and Information Technologists, 1992)

Recently, there have been various attempts to combine the strengths of similarity-based learning (SBL) and explanation-based learning (EBL) in a single learning system. We describe a graph-based learning method called ...
Text categorization as an information retrieval task

Paijmans, H (South African Computer Society (SAICSIT), 1998)

A number of methods for feature reduction and feature selection in text classification and information retrieval systems are compared. These include feature sets that are constructed by Latent Semantic Indexing, 'local ...
