On the view of input and output, information value-added, this paper sets forth the double-benefits in the library special construction, and the contents of special collections and special services in all kinds of libraries, and the importance of special database constructing.
It is discussed that Internet can improve the quality of information transmission and increase the velocity as well, the acquisitive cost of information decreases gradually, so the overall information amount of what the entity acquire is increasing rapidly, then there will be a great information increment.
establishing the smooth information management system and developing the application room for information increment: enhance the scientific level of management and decision-making based on the data analysis;
The research of this paper is propitious to the news information resource integration and news information cooperative production of the traditional press group. And it can improve the story level, improve the core competence, and extend the space of information increment.
As the rough primary information of current port and shipping EDI(electronic data interchange) is out of order, it must be translated into metainformation and value-added information in order to be effectively used.
The conclusions we have drawn are as follows: 1. With the data digging from the rough date transferred through the port and shipping EDI platform, so many functions of the value-added information can be realized such as container market analyzing, the compiling and analyzing of container freight index and the optimization pf the container management, etc.
The paper analyzing three aspects of information added value:its conception,and the relation between library and references,the mode of information service. Finally the paper draws conclusion that pursing the maximizing of information added value is a perpetual theme of library and providing information added value service is the core of future library work.
The requirements specifications developed are described in terms of a functional model, which is then extended to form an information architecture.
Distinct from the functional model, the information architecture provides an indication as to the architectural structure of subsequently developed Internet-based control systems.
Three general control structures are generated from the analysis of an information architecture.
The resulting conceptual model is referred to as the information architecture, and is an integration of three formal object-oriented analysis models with each a specific view on the application domain.
Furthermore, the information architecture forms an abstraction of an underlying grammar, called the information grammar, for the communication within the application domain.
