A Study of Path Completion Techniques in Web Usage Mining Path completion is a critical and difficult task in the preprocessing phase of web usage mining. We mold the data preprocessing phase to accomplish our goal to mine websites designed using a content management system (cms). The data preprocessing phase includes data cleaning, user identification, session identification, site structure and link details formation, path completion and event generation. The paper includes work on path completion by considering different types of path generated in accessing the website designed using cms and gives a novel algorithm to form the path.
