Classifying Structured Web Sources Using Aggressive Feature Selection

Abstract

Abstract:This paper studies the problem of classifying structured data sources on the Web. While prior works use all features, once extracted from search interfaces, we further refine the feature set. In our research, each search interface is treated simply as a bag-of-words. We choose a subset of words, which is suited to classify web sources, by our feature selection methods with new metrics and a novel simple ranking scheme. Using aggressive feature selection approach, together with a Gaussian process classifier, we obtained high classification performance in an evaluation over real web data.
