Classifying web pages using information extraction patterns - Preliminary results and findings

초록

Web page classification plays an essential role in facilitating more efficient information retrieval and information processing. Conventionally, web text documents are represented by term frequency matrix for classification purpose. However, considering the limitations of representing documents using terms or keywords, we propose to represent web pages using information extraction patterns that are identified within the pages respectively. In this paper, we present the results as well as the findings obtained from our preliminary experiments. Our experimental results indicate that the existence of a word in different contexts has different impact to the classification task. Thus, the extraction patterns used to represent each document are more semantically meaningful and give better insight to web classification in comparison with keywords. © 2010 IEEE.
