Abstract
In one embodiment, a method for transforming training data to improve data classification is disclosed. The method comprises extracting concepts from a training data set. The method comprises computing frequency of occurrence of each concept in each category and removing concepts from the data records when the frequency of occurrence of a concept in a category is less than a threshold frequency value. Further, the method comprises computing a percentage contribution of each concept of remaining concepts in each category upon removing the concepts and eliminating concepts, from the remaining concepts, contributing equally to each category based on the percentage contribution of each concept to provide a reformed training data set. Further, the method comprises appending a category name to a corresponding data record in the reformed training data set based on a normalized frequency of occurrence of the concept in a category to improve data classification.
