Using bag-of-concepts to improve the performance of support vector machines in text categorization [PDF]

open access: yes, 2004
This paper investigates the use of concept-based representations for text categorization. We introduce a new approach to create concept-based text representations, and apply it to a standard text categorization collection. The representations are used as

A study on mutual information-based feature selection for text categorization [PDF]

open access: yes, 2007
Feature selection plays an important role in text categorization. Automatic feature selection methods such as document frequency thresholding (DF), information gain (IG), mutual information (MI), and so on are commonly applied in text categorization ...

Improving Large-Scale k-Nearest Neighbor Text Categorization with Label Autoencoders

open access: yesMathematics, 2022
In this paper, we introduce a multi-label lazy learning approach to deal with automatic semantic indexing in large document collections in the presence of complex and structured label vocabularies with high inter-label correlation. The proposed method is

Keyword extraction for text categorization [PDF]

open access: yesProceedings of the 2005 International Conference on Active Media Technology, 2005. (AMT 2005)., 2005
Text categorization (TC) is one of the main applications of machine learning. Many methods have been proposed, such as Rocchio method, Naive bayes based method, and SVM based text classification method. These methods learn labeled text documents and then construct a classifier. A new coming text document's category can be predicted.

Distributional Features for Text Categorization [PDF]

open access: yesIEEE Transactions on Knowledge and Data Engineering, 2006
Text categorization is the task of assigning predefined categories to natural language text. With the widely used 'bag of words' representation, previous researches usually assign a word with values such that whether this word appears in the document concerned or how frequently this word appears. Although these values are useful for text categorization,
