Abstract

Web personalization is the process of customizing a Web site to the needs of specific users, taking advantage of the knowledge acquired from the analysis of the user's navigational behavior (usage data) in correlation with other information collected in the Web context, namely, structure, content, and user profile data. Due to the explosive growth of the Web, the domain of Web personalization has gained great momentum both in the research and commercial areas. In this article we present a survey of the use of Web mining for Web personalization. More specifically, we introduce the modules that comprise a Web personalization system, emphasizing the Web usage mining module. A review of the most common methods that are used as well as technical issues that occur is given, along with a brief overview of the most popular tools and applications available from software vendors. Moreover, the most important research initiatives in the Web usage mining and personalization areas are presented.

4.2 Web Data Abstractions

In the Web domain, several abstractions are mentioned, concerning Web usage, content, and structure. The W3C Web Characterization Activity WCA has published a draft establishing precise semantics for concepts such as Web site, user, user sessions, server sessions, pageviews, and clickstreams.

A Web site is defined as a collection of interlinked Web pages, including a host page, residing at the same network location. A user is defined to be the principal using a client to interactively retrieve and render resources or resource manifestations. In the Web context, a user is an individual that is accessing files from a Web server, using a browser. A user session is defined as a delimited set of user clicks across one or more Web servers. A server session is defined as a collection of user clicks to a single Web server during a user session. It is also called a visit. A pageview is defined as the visual rendering of a Web page in a specific environment at a specific point in time. In other words, a pageview consists of several items, such as frames, text, graphics, and scripts that construct a single Web page. A clickstream is a sequential series of pageview requests, made from a single user.

4.3 Data Preprocessing

There are some important technical issues that must be taken into consideration during this phase in the context of the Web personalization process, because it is necessary for Web log data to be prepared and preprocessed in order to use them in the consequent phases of the process. An extensive description of data preparation and preprocessing methods can be found in Cooley et al. [1999a].
