Experimental Evaluation Of Different Classification Techniques For Web Page Classification

Abstract

Classification of web pages is essential for improving the quality of web search, focused crawling, development of web directories like Yahoo, ODP etc. This paper compares various classification techniques for the task of web page classification. The classification techniques compared include k-Nearest Neighbours (KNN), Naive Bayes (NB), Support Vector Machine (SVM), Classification and Regression Trees (CART), Random Forest (RF) and Particle Swarm Optimization (PSO).Impact of using different representations of web pages is also studied. The different representations of the web pages that are used comprise Boolean, bag-of-words and Term Frequency and Inverse Document Frequency (TFIDF). Experiments are performed using WebKB and R8 data sets. Accuracy and F-measure are used as the evaluation measures. Impact of feature selectionon the accuracy of the classifier is moreover demonstrated.
