<p><P>PROBLEM TO BE SOLVED: To explicitly indicate a standard in selecting a retrieval condition concerning a retrieval system and a program. <P>SOLUTION: A retrieval system is provided with; an inputting means (1); a retrieval condition-generating means (21) which combines inputted retrieval conditions to generate a new retrieval condition; a retrieval means (22) which extracts data which satisfy the inputted retrieval conditions and the generated retrieval condition; a registering means (23) which registers the retrieval conditions and the extracted data; a control means (24) which generates closed line/curved line graphics having areas according to the number of data which satisfy each of the registered retrieval conditions, computes the ratio of the number of the data which satisfy each of the retrieval conditions to the number of the overlapping data which satisfy both each of the retrieval conditions and other retrieval conditions, determines the overlapping parts of the closed line/curved line graphics, and outputs the graphics; and a displaying means (3) which displays each of the closed line/curved line graphics outputted from the control means. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
