Abstract

An information navigation system for supporting browsing of data which are linked mutually includes an starting point determination supporter, a browsing supporter, and a positioning supporter. The starting point determination supporter supports detection of first data being a starting point for an information navigation. The browsing supporter displays the first data and second data linked to the first data as in a virtual space, to allow a user to select data to be browsed next. The positioning supporter displays a current browsing position on a map which indicates a relation between all data.

Claims

1. A computer readable storage medium having instructions encoded thereon, when executed by a computer cause the computer to execute operations comprising:

displaying on a display section a plurality of first data points of a group of data of a plurality of groups of data as candidates for a starting point from where information navigation through the group of data of the plurality of groups of data starts, and supporting a user to select one of the plurality of the first data points as the starting point;

providing the user with a first image indicating the selected starting point and a second data point of the group of data of the plurality of groups of data, the second data point linked to the starting point to allow the user to select data to be browsed next on the display section; and

providing the user with a global information navigation map indicating all data points of all the plurality of groups of data, including indication of the starting point, the second data point and the link between the starting point and the second data point, indicating interrelationship among all the data points of all the plurality of groups of data, and indicating in the global information navigation map a current browsing position showing which one of the data points from all the data points of all the plurality of groups of data is a data point currently being browsed,

wherein the first image shows the starting point as a first level data and the second data point as a second level data by icons indicating attributes of level data and configurable to moving the icon of the second level data to around the icon of the first level data, and

wherein the current browsing position and the link that has been traced are displayed by a specific color.

2. The computer readable storage medium according to claim 1, further having instructions encoded thereon causing the computer to further execute operations comprising:

receiving a keyword input by the user;

extracting from the group of data a plurality of data related to the keyword; and

classifying the extracted plurality of data into a plurality of groups based on a number of links between the extracted data.

3. The computer readable storage medium according to claim 1, wherein each of the starting point and the second data point is shown in the first image as an icon and label which indicate an attribute and content of the data to be displayed.

4. The computer readable storage medium according to claim 1, further having instructions encoded thereon causing the computer to further execute providing the user with history information of links that have been traced and data points that have been browsed on the global information navigation map.

5. The computer readable storage medium according to claim 1, further having instructions encoded thereon causing the computer to further execute switching between the first image and the global information navigation map according to an operation by the user.

6. The computer readable storage medium according to claim 1, further having instructions encoded thereon causing the computer to further execute providing the user a history image showing the first image shown in the past, wherein the first image shown in the past shows an arrangement of the first level data and the second level data shown in the past.

7. The computer readable storage medium according to claim 1, wherein the first image shows the icon of the second level data around the icon of the first level data.

8. A method for information navigation on a computer, comprising:

displaying a list of potential first data points of a group of data of a plurality of groups of data to a user using a computer;

selecting by the user one of the first data points of the group of data of the plurality of groups of data as a starting point;

displaying a first image indicating the selected starting point and a navigable second data point of the group of data of the plurality of groups of data, the second data point linked to the starting point; and

displaying a global information navigation map indicating all data points of all the plurality of groups of data, including indication of the starting point, the second data point and the link between the starting point and the second data point, indicating interrelationship among all the data points of all the plurality of groups of data, and indicating in the global information navigation map a current browsing position showing which one of the data points from all the data points of all the plurality of groups of data is a data point currently being browsed,

wherein the first image shows the starting point as a first level data and the second data point as a second level data by icons indicating attributes of level data and configurable to moving the icon of the second level data to around the icon of the first level data, and

wherein the current browsing position and the link that has been traced are displayed by a specific color.

9. An information navigation apparatus, comprising:

a display device displaying a list of potential first data points of a group of data of a plurality of groups of data to a user; and

a computer processor

supporting the user to select one of the first data points of the group of data of the plurality of groups of data displayed on the display device,

displaying a first image indicating the selected starting point and a navigable second data point of the group of data of the plurality of groups of data, the second data point linked to the starting point on the display device, wherein the first image shows the starting point as a first level data and the second data point as a second level data by icons indicating attributes of level data and configurable to moving the icon of the second level data to around the icon of the first level data,

displaying on the display device a global information navigation map indicating all data points of all the plurality of groups of data, including indication of the starting point, the second data point and the link between the starting point and the second data point, indicating interrelationship among all the data points of all the plurality of groups of data, and indicating in the global information navigation map a current browsing position showing which one of the data points from all the data points of all the plurality of groups of data is a data point currently being browsed, and

displaying the current browsing position and the link that has been traced on the display device in a specific color.
