Typically location descriptions combine references to named geographical features with vague spatial relational terms, such as near, north of and at that relate locations to the features. Here we describe a system for generating location descriptions, that combines spatial templates, that model the applicability of different spatial relations relative to a reference location, with toponyms in the vicinity of the described location that are selected according to aspects of salience. The toponyms are retrieved from a gazetteer service based on OpenStreetMap for which we create a hierarchical feature classification scheme to facilitate selection of toponyms according to distinctiveness of their feature types and other aspects of salience. The advantages of the approach are demonstrated in a user study, relative to an existing state of the art system and to other baseline approaches that include manually created captions and the automated methods of two widely used photo captioning systems.

Modelling vague places with knowledge from the Web / Christopher B. Jones in International journal of geographical information science IJGIS, vol 22 n° 10 (october 2008)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 22 n° 10 (october 2008) . - pp 1045 - 1065 Titre : Modelling vague places with knowledge from the Web Type de document : Article/Communication Auteurs : Christopher B. Jones, Auteur ; Ross S. Purves, Auteur ; P.D.

It is common for users to employ vernacular names that have vague spatial extent and which do not correspond to the official and administrative place name terminology recorded within typical gazetteers. There is a need therefore to enrich gazetteers with knowledge of such vague places and hence improve the quality of place name-based information retrieval. Here we describe a method for modelling vague places using knowledge harvested from Web pages. It is found that vague place names are frequently accompanied in text by the names of more precise co-located places that lie within the extent of the target vague place. Density surface modelling of the frequency of co-occurrence of such names provides an effective method of representing the inherent uncertainty of the extent of the vague place while also enabling approximate crisp boundaries to be derived from contours if required. The method is evaluated using both precise and vague places. The use of the resulting approximate boundaries is demonstrated using an experimental geographical search engine.

The design and implementation of spirit: a spatially aware search engine for information retrieval on the Internet / Ross S. Purves in International journal of geographical information science IJGIS, vol 21 n° 6-7 (july 2007)

In this paper we describe the design, implementation and evaluation of a spatially aware search engine which is capable of handling queries in the form of the triplet of . The process of identifying geographic references in documents and assigning appropriate footprints to documents, to be stored together with document terms in an appropriate indexing structure allowing real-time search, is described. Methods allowing users to query and explore results which have been relevance-ranked in terms of both thematic and spatial relevance have been implanted and a usability study indicates that users are happy with the range of spatial relationships available and intuitively understand how to use such a search engine. Normalised precision for 38 queries, containing four types of spatial relationships, is significantly higher (p Numéro de notice : A2007-268 Affiliation des auteurs : COGIT+Ext (1988-2011) Thématique : GEOMATIQUE Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1080/13658810601169840 Date de publication en ligne : 14/06/2007 En ligne : https://doi.org/10.1080/13658810601169840 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=28631 [article]

A filter flow visual querying language and interface for spatial databases / A.J. Morris in Geoinformatica, vol 8 n° 2 (June - August 2004)  

Public [article]  inGeoinformatica > vol 8 n° 2 (June - August 2004) Titre : A filter flow visual querying language and interface for spatial databases Type de document : Article/Communication Auteurs : A.J. Morris, Auteur ; B.A. El-Geresy, Auteur ; Christopher B. Jones, Auteur ; A.I. Abdelmoty, Auteur Année de publication : 2004 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Bases de données localisées [Termes IGN] base de données localisées [Termes IGN] langage de requête [Termes IGN] relation spatiale [Termes IGN] requête spatiale [Termes IGN] système d'information géographique Résumé : (Auteur) In this paper a visual approach to querying in spatial databases is presented. A filter flow methodology is used to consistently express different types of queries in these systems. Filters are used to represent operations on the database and pictorial icons are used throughout the language for filters, operators and spatial relations. Different granularities of the relations are presented in a hierarchical fashion for spatial constraints. The language framework and functions are described and examples are used to demonstrate its capabilities in representing different levels of queries, including spatial joins and composite spatial joins. Here, the primary focus is on the query language itself but an overview of the implemented interface of the language is also provided.
