Evaluations of User Creation Personal Portal Page Using DACS Web Service

A personal portal, which is an entrance wherein each user can acquire the information that s/he is interested in on a network, is often used as an alternative means of communication. However, there are a number of problems with the existing personal portals. For example, because the Web page as a personalportal is generated by the program located on the specific Web server which is managed by a system administrator, it is not always ideal for all users. To solve this kind of problems, we developed two Web Service functions, which are realized on the network by introducing the Destination Addressing ControlSystem (DACS) Scheme. These two Web Service functions are as next. The first is the function to extract the data for each user from a database and display it on the Web browser. The second is the function to retrieve the data for each user from a document medium and display it on the Web browser. Through these Web Service functions, each user can easily create a customized personal portal that displays personalinformation. In this paper, the above two functions are extended to manage information not only for each user but also for each group of users and for all users, and the extended two functions are integrated as a DACS Web Service. By using the DACS Web Service, each user can create and customize the Web page as a personal portal for practical usage in an individual organization. After the prototype system’s implementation, evaluations are performed.
