摘要
Online incremental learning is one of the emerging research interests among the researchers in the recent years.The sentiment classification through the online incremental learning faces many challenges due to the limitations in the memory and the computing resources available for processing the online reviews.This work has introduced an online incremental learning algorithm for classifying the train reviews.The sentiments available in the reviews provided for the public services are necessary for improving the quality of the service.This work proposes the online kernel optimizationbased support vector machine(OKO-SVM)classifier for the sentiment classification of the train reviews.This paper is the extension of the previous work kernel optimizationbased support vector machine(KO-SVM).The OKO-SVM classifier uses the proposed fuzzy bound for modifying the weight for each incoming review database for the particular time duration.The simulation uses the standard train review and the movie review database for the classification.From the simulation results,it is evident that the proposed model has achieved a better performance with the values of 84.42%,93.86%,and 74.56%regarding the accuracy,sensitivity,and specificity while classifying the train review database.
