Abstract

A computer-implemented method involving a corpus of documents. The method includes accepting search criteria from a user, the search criteria including a domain identifier identifying a domain and including a filter condition specifying a geometric relationship between co-referenced locations; in response to accepting the search criteria from the user, searching among the corpus of documents to identify a set of documents, wherein each document among the set of documents contains anywhere within the document location-related information that refers to a location within the domain and satisfies the filter condition, and wherein the set of documents only includes documents that satisfy the filter condition; and identifying to the user the documents in the set of documents.

Claims

1. A computer-implemented method of displaying information about a document that includes a plurality of spatial identifiers each of which identifies a corresponding location within a metric space and at least two of the locations of the spatial identifiers have a geometric relationship to each other, said method comprising:

displaying at least a portion of content from the document, wherein the at least one portion of content is a natural language;

displaying a map image of a portion of the metric space;

displaying a visual indicator at a position on the map image representing the location that corresponds to one of said plurality of spatial identifiers;

visually indicating that the location corresponding to the visual indicator has associated data that characterizes the geometric relationship between that location and the location of another spatial identifier in the document, wherein the geometric relationship is determined by a path hierarchy for each location; and

visually differentiating, by visually promoting and highlighting differently, the at least two corresponding locations based on attributes that are defined with reference to the document, wherein the locations that are metonymic are given less prominent visual emphasis than other locations.

2. The computer-implemented method of claim 1, wherein the geometric relationship is one of being a container of another location.

3. The computer-implemented method of claim 1, wherein the geometric relationship is one of being contained in another location.

4. The computer-implemented method of claim 1, wherein the geometric relationship is one of being overlapping with another location.

5. The computer-implemented method of claim 1, wherein the geometric relationship is one of being a neighbor of another location.

6. The computer-implemented method of claim 1, wherein the path hierarchy is organized into a directed acyclic graph structure.

7. A computer-implemented method of displaying information about a document that includes a spatial identifier that identifies a corresponding location within a metric space and wherein that spatial identifier is characterized by a semantic type that is determined by the use of the spatial identifier within the document, said method comprising:

displaying at least a portion of content from the document, wherein the at least one portion of content is a natural language;

visually identifying the spatial identifier within a displayed visual representation of the content from the document;

visually indicating the semantic type of the spatial identifier wherein the semantic type is determined by a path hierarchy for each location; and

visually differentiating, by visually promoting and highlighting differently, two or more corresponding locations based on attributes that are defined with reference to the document, wherein the locations that are metonymic are given less prominent visual emphasis than other locations.

8. The computer-implemented method of claim 7, further comprising:

along with the displayed visual representation of content, also displaying a map image of a portion of the metric space; and

displaying a visual indicator at a position on the map image representing the location that corresponds to the spatial identifier.

9. The computer-implemented method of claim 7, wherein the semantic type is a context-dependent property of the spatial indicator.

10. The computer-implemented method of claim 7, wherein the semantic type is place-of-author.

11. The computer-implemented method of claim 7, wherein the semantic type is place-of-subject.

12. The computer-implemented method of claim 7, wherein the semantic type is literal location.

13. A computer-implemented method of displaying information about a document that includes a spatial identifier that identifies a corresponding location within a metric space and wherein that spatial identifier is a semantic type, said method comprising:

displaying at least a portion of content from the document, wherein the at least one portion of content is a natural language;

displaying a map image of a portion of the metric space;

displaying a visual indicator at a position on the map image representing the location that corresponds to the spatial identifier;

visually indicating the semantic type of the spatial identifier wherein the semantic type is determined by a path hierarchy for each location, and

visually differentiating, by visually promoting and highlighting differently, two or more corresponding locations based on attributes that are defined with reference to the document, wherein the locations that are metonymic are given less prominent visual emphasis than other locations.

14. A non-transitory computer readable medium storing code for use with a document that includes a plurality of spatial identifiers each of which identifies a corresponding location within a metric space and at least two of the locations of the spatial identifiers have a geometric relationship to each other, wherein said code when executed on a computer system causes the computer system to:

display at least a portion of content from the document, wherein the at least one portion of content is a natural language;

display a map image of a portion of the metric space;

display a visual indicator at a position on the map image representing the location that corresponds to one of said plurality of spatial identifiers;

visually indicate that the location corresponding to the visual indicator has associated data that characterizes the geometric relationship between that location and the location of another spatial identifier in the document wherein the geometric relationship is determined by a path hierarchy for each location; and

visually differentiate, by visually promoting and highlighting differently, the at least two corresponding locations based on attributes that are defined with reference to the document, wherein the locations that are metonymic are given less prominent visual emphasis than other locations.

15. A non-transitory computer readable medium storing code for use with a document that includes a spatial identifier that identifies a corresponding location within a metric space and wherein that spatial identifier is characterized by a semantic type that is determined by use of the spatial identifier within the document, wherein said code when executed on a computer system causes the computer system to:

display at least a portion of content from the document, wherein the at least one portion of content is a natural language;

visually identify the spatial identifier within a displayed visual representation of the content from the document;

visually indicate the semantic type of the spatial identifier wherein the semantic type is determined by a path hierarchy for each location; and

visually differentiate, by visually promoting and highlighting differently, two or more corresponding locations based on attributes that are defined with reference to the document, wherein the locations that are metonymic are given less prominent visual emphasis than other locations.

16. A method of displaying information contained within a document, the method comprising:

displaying at least a portion of content from the document, wherein the at least one portion of content is a natural language;

receiving information that identifies a first portion of the document containing a first identifier that references a first location in a metric vector space;

receiving information that identifies a second portion of the document containing a second identifier that references a second location in the metric vector space;

receiving information describing a geometric relationship between the first location and the second location;

displaying a map of a portion of the metric vector space, a domain encompassing at least a part of one of the first and second locations;

displaying at least one of the first location and the second location on the map, wherein a mode of displaying the at least one of the first location and the second location is determined by the geometric relationship between the first and second locations wherein the geometric relationship is determined by a path hierarchy for each location; and

differentiating visually, by visually promoting and highlighting differently, the first and second locations based on attributes that are defined with reference to the document wherein the locations that are metonymic are given less prominent visual emphasis than other locations.

17. A method of displaying information contained within a document, the method comprising:

identifying a portion of the document that contains an identifier that references a location in a metric vector space;

analyzing the portion of the document to obtain a semantic category of the identifier, the semantic category identifying a sense in which an author of the document intended to use the identifier in the portion of the document;

displaying at least a portion of content from the document, wherein the at least one portion of content is a natural language;

displaying a map of the domain of the metric vector space, the domain encompassing at least a part of the location referenced by the identifier;

displaying on the map of the domain the location referenced by the identifier, wherein a mode of displaying the location referenced by the identifier is determined by the semantic category of the identifier wherein the semantic category is determined by a path hierarchy for each location; and

differentiating visually, by visually promoting and highlighting differently, at least two locations based on attributes that are defined with reference to the document, wherein the locations that are metonymic are given less prominent visual emphasis than other locations.
