31、is crucial to classify properly users and their roles before further discussion. The present study adopts WIS classifications from Isakowitz et al. (1998), and suggests some tentative user requirements dimensions, which

32、are most synthesized from several recent studies (Armstron</p><p>　　(1) the acquisition of information;</p><p>　　(2) communication;</p><p>　　(3) exploration (e.g. surfing); and</
