Users of Web-based software encounter growing complexity of the software resulting from the increasing amount of information and service offering. As a consequence, the likelihood that users employ the software in a manner compatible with the provider´s interest decreases. An approach at addressing this problem is to adapt the software´s behavior during operation to the context in which it is being used. This dissertation addresses the question of how context-awareness can be applied in a systematic process for Web application development: that is, in a Web Engineering process. A model for representing an application´s context factors in ontologies is presented. A corresponding Web software architecture for context is discussed; in particular, the CATWALK software framework, an implementation based on an XML stack is described, that provides mechanisms for interpreting application and context models to generate an adaptive application.
