In this poster, we describe WOOD (Web-based Objectoriented Desktop) which is a web-based personalization information system. It provides various types of application components to help users gather and manipulate information over the Internet e ectively. Components, with di erent capabilities ranging from fetching from search engines to getting latest stock quote or even to clip part of a web pages, are available to the users. Users can add and layout those components in their personal page with WOOD as if they were working in the local window operating system. Since WOOD is designed to be open and extensible, third party developers can easily develop their own components and plug into WOOD. This poster brie y describes the architecture and the prototype implementation of WOOD. Keywords Information Retrieval, Personalization, Web applications, User Interface
