PURPOSE:To realize an information retrieving viewer system capable of addition and change by an individual and securing enough secrecy. CONSTITUTION:The system consists of an IC card 100 provided with a memo file storing a certification number and additional data at each node and an additional changing partial tree patch storing the changing contents concerning a node whose decision tree is to be changed, a remote host 300 storing display data at each node and an information retrieving viewer system 200 consisting of a display means, an input means, an IC card reading means, a decision tree storage means storing a knowledge base by the form of the decision tree consisting of hierarchical nodes, a communication means for communicating with a remote host and a main control part controlling each means. When the IC card 100 is connected, the main control part confirms the certification number and after then, makes a node at a lowest layer read display data and additional data respectively stored in the remote host 300 and the memo file and display them on the display means by integrating. |
