Systems and methods for generating and correcting location references extracted from text

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.
