GIPSY: automated geographic indexing of text documents
TLDR
An algorithm which automatically extracts geopositional coordinate index terms from text to support georeferenced document indexing and retrieval is presented.Abstract:
In this paper we present an algorithm which automatically extracts geopositional coordinate index terms from text to support georeferenced document indexing and retrieval. Under this algorithm, words and phrases containing geographic place names or characteristics are extracted from a text document and used as input to database functions which use spatial reasoning to approximate statistically the geoposition being referenced in the text. We conclude with a discussion of preliminary results and future work.read more

Large-Scale Named Entity Disambiguation Based on Wikipedia Data
TL;DR: Through a process of maximizing the agreement between the contextual information extracted from Wikipedia and the context of a document, as well as the agreement among the category tags associated with the candidate entities, the implemented system shows high disambiguation accuracy on both news stories and Wikipedia articles.

Spatially coding and displaying information
TL;DR: In this paper, a computer system (20) includes storage system (22) which contains information in the form of documents, along with a spatial information about the documents, and a map interface (80) through which users can query the storage and view a representation of the query results arranged on a map.

Toponym resolution in text: annotation, evaluation and applications of spatial grounding
TL;DR: This article defined the task of automatic toponym resolution as computing the mapping from occurrences of names for places as found in a text to a representation of the extensional semantics of the location referred to (its referent), such as a geographic latitude/longitude footprint.
