Abstract

The rapid development of Web 2.0 brings the flourish of web reviews. Traditional web review data extraction methods suffer from poor performance in dealing with massive data. To solve this problem, we propose an effective and efficient approach to extract web reviews based on Hadoop. It overcomes inefficiency when dealing with large-scale data, and enables the accuracy and efficiency in extracting the massive data sets. Our proposed approach consists of two components: a review record extraction algorithm based on node similarity, and a review content extraction algorithm based on the text depth. We design a Hadoop-based web reviews automatic extraction system. At last, we test the extraction system using the massive web reviews page sets. The experimental results show that this extraction system can achieve accuracy of more than 96%, and also can obtain a higher speedup, compared with the traditional web extraction.
