Handling users local contexts in web 2.0: Use cases and challenges

Abstract

Creating, updating, and aggregating Web contents from different Web users and sites form the heart idea of Web 2.0. However, Web users originate from different communities, and follow their own semantics (referred to as local contexts in this paper) to represent and interpret Web contents. Therefore, several discrepancies could rise up between the semantics of Web authors and readers. In this paper, we present several Web 2.0 use cases, and illustrate the possible challenges and trends to handle the local contexts of Web users in these use cases.
