In an information processing system, an information storing unit stores a plurality of main information sets along with time information sets. A retrieval condition input unit inputs retrieval conditions for the main information sets. A retrieval execution unit performs a retrieval upon the main information sets along with the time information sets by using the retrieval conditions. A cell output information generating unit receives retrieved main information sets along with the time information sets and generates a number of the main information sets and a tendency of the number of the main information sets to change with respect to time for each of cells defined by the retrieval conditions. A cell output unit outputs each of the cell and displays each of the cells at a location on a matrix designated by the retrieval conditions.
