Abstract

Under one aspect, an interface program stored on a computer-readable medium causes a computer system with a display device to perform the functions of: displaying a document on the display device; displaying a selectable button for requesting location-related information pertaining to the document; accepting a user selection of the button as a request to view the location-related information pertaining to the document; in response to the request, requesting and receiving metadata identifying candidate location references within the document; displaying on the display device a map with visual indicators representing at least a subset of the plurality of location references within the document; and displaying on the display device the document with visual indicators representing at least a subset of the plurality of location references within the document.

Claims

1. An interface program stored on a computer-readable medium for causing a computer system with a display device to perform the functions of:

displaying a document on the display device;

displaying a selectable button for requesting location-related information pertaining to the document;

accepting a user selection of the button as a request to view the location-related information pertaining to the document;

in response to the request, requesting and receiving metadata identifying candidate location references within the document;

displaying on the display device a map with visual indicators representing at least a subset of the plurality of location references within the document; and

displaying on the display device the document with visual indicators representing at least a subset of the plurality of location references within the document.

2. The interface program of claim 1, wherein the selection of the button comprises a single mouse click.

3. The interface program of claim 1, wherein requesting and receiving the plurality of location references within the document comprises transmitting the document to an external server.

4. The interface program of claim 1 for causing the computer system to further perform the functions of displaying an interface allowing the user to edit the metadata.

5. The interface program of claim 4 wherein the interface causes the computer system to perform at least one of the following functions:

associating the metadata with a previously unidentified location reference within the document, removing metadata that inappropriately identifies a location reference within the document, modifying coordinates associated with a location reference within the document, and modifying a confidence score associated with a location reference within the document.

6. A method of displaying information about a document, the method comprising:

displaying a document on the display device;

displaying a selectable button for requesting location-related information pertaining to the document;

accepting a user selection of the button as a request to view the location-related information pertaining to the document;

in response to the request, requesting and receiving metadata identifying candidate location references within the document;

displaying on the display device a map with visual indicators representing at least a subset of the plurality of location references within the document; and

displaying on the display device the document with visual indicators representing at least a subset of the plurality of location references within the document.

7. The method of claim 6, wherein the selection of the button comprises a single mouse click.

8. The method of claim 6, wherein requesting and receiving the plurality of location references within the document comprises transmitting the document to an external server.

9. The method of claim 6, further comprising displaying an interface allowing the user to edit the metadata.

10. The method of claim 6, wherein the interface allows the user to make at least one of the following edits:

associating the metadata with a previously unidentified location reference within the document, removing metadata that inappropriately identifies a location reference within the document, modifying coordinates associated with a location reference within the document, and modifying a confidence score associated with a location reference within the document.

11. An interface program stored on a computer-readable medium for causing a computer system with a display to perform the functions of:

displaying a document on the display;

displaying metatdata associated with the document on the display, the displayed metadata comprising a confidence score indicating the likelihood that the author intended for the document to refer to a candidate location; and

providing an interface through which a user can alter the confidence score in the metadata.

12. A method for displaying and altering information about a document, the method comprising:

displaying a document on a display;

displaying metatdata associated with the document on the display, the displayed metadata comprising a confidence score indicating the likelihood that the author intended for the document to refer to a candidate location; and

providing an interface through which a user can alter the confidence score in the metadata.
