Abstract: Under one aspect, an interface program stored on a computer-readable medium causes a computer system to perform the functions of: accepting search criteria from a user, the search criteria including a free-text query and a domain identifier, the domain identifier identifying a domain in a metric vector space; in response to accepting the search criteria from the user, obtaining a set of document-location tuples from a corpus of documents, each document-location tuple satisfying the search criteria from the user, each location having associated cartographic display attributes; displaying a visual representation of the domain having an average spatial scale; selecting a subset of the set of document-location tuples based on the cartographic display attributes and on the average spatial scale of the visual representation of the domain; and displaying a plurality of visual indicators representing the selected subset of document-location tuples.

Abstract: Under one aspect, an interface program causes a computer system to accept search criteria including a free-text query and a domain identifier identifying a domain in a metric vector space; obtaining a set of document-location tuples satisfying the search criteria from a corpus of documents; and determining whether the tuples are associated with a single document or a plurality of documents. If the tuples are associated with multiple documents, the program causes the computer to display a visual domain representation, visual indicators representing the tuples, and, for each tuple, a document summary including a document identifier and a document text substring shorter than a specified length. If the tuples are associated with a single document, the program causes the computer to display a visual domain representation, visual indicators representing the tuples, a document summary including an identifier for the document, and a document text substring longer than the specified length.
