AbstractA number of similarity metrics have been used to measure the degree of web page changes in the literature. In this paper, we define criteria for web page changes to evaluate the effectiveness of the metrics. Using real web pages and synthesized pages, we analyze the five existing metrics (i.e., the byte-wise comparison, the TF∙IDF cosine distance, the word distance, the edit distance, and the shingling) under the proposed criteria. The analysis result can help users select an appropriate metric for particular web applications.
