  abstract = {In recent years, many algorithms for the Web have been developed that work with information units distinct from individual web pages. These include segments of web pages or aggregation of web pages into web communities. Such logical information units improve a variety of web algorithms and provide the building blocks for the construction of organized information spaces such as digital libraries. In this paper, we focus on a type of logical information units called "compound documents". We argue that the ability to identify compound documents can improve information retrieval, automatic metadata generation, and navigation on the Web. We propose a unified framework for identifying the boundaries of compound documents, which combines both structural and content features of constituent web pages. The framework is based on a combination of machine learning and clustering algorithms, with the former algorithm supervising the latter one. We also propose a new method for evaluating quality of clusterings, based on a user behavior model. Experiments on a collection of educational web sites show that our approach can reliably identify most of the compound documents on these sites.}
