Users sharing and authoring of Web contents via different Web sites is the main idea of the Web 2.0. However, Web users belong to different communities and follow their own semantics (referred to as contexts) to represent and interpret Web contents. Therefore, they encounter discrepancies when they have to interpret Web contents authored by different persons. This paper proposes a context-aware interaction approach that helps Web authors annotate Web contents with their local context information, so that it becomes possible for Web browsers to personalize these contents according to different users’ local contexts.
