This paper considers the problem of extracting geoattributed entities from natural language texts to visualize the spatial relations of geographical objects. For visualization we use the technology of automated generation of schematic maps as subject-oriented components of geographic information systems. The paper describes the information technology that allows extracting geoattributed entities from natural language texts by combining several approaches. These are the neural network approach, the rule-based approach and the approach based on the use of lexico-syntactic patterns for the analysis of natural language texts. For data visualization we propose to use automated geocoding tools in conjunction with the capabilities of modern geographic information systems. The result of this technology is a cartogram that displays the spatial relations of the objects mentioned in the text.

Resumen El ordenamiento territorial como disciplina ha venido aplicándose alrededor del mundo desde hace ya mucho tiempo; evidentemente sus procesos se han optimizado, y han evolucionado no solo técnica sino conceptualmente. Sin embargo, la velocidad a la que crecen actualmente las ciudades genera una brecha cada vez mayor con los procesos de planificación, que difícilmente pueden producir políticas o acciones urbanísticas que lleguen a tiempo a los territorios.La aparición en escena de los Sistemas de Información Geográfica ha ofrecido una nueva variedad de métodos y herramientas que en concordancia con los acelerados procesos de desarrollo urbano, han fortalecido la cultura de la planeación en la reducción de sus tiempos de análisis, la adquisición de datos y fundamentalmente en la toma de decisiones. En ese sentido, este artículo plantea la aplicabilidad de los SIG en el Ordenamiento Territorial, con base en la profunda relación existente entre los componentes básicos del primero y las metodologías de trabajo del segundo, y mediante ejemplos de algunas de las aplicaciones prácticas que se le pueden dar a esta nueva tecnología en el ámbito del urbanismo. Palabras ClavePlanificación urbana, Urbanismo, Relaciones Espaciales, Territorio. Abstract Urban planning as a discipline has been used around the world since long time ago; obviously it´s processes have improved and it has evolved not only technically but conceptually. However, the accelerated growth process of the cities is producing an every time bigger breach with the planning processes, that hardly produce on time policies or urban actions to apply on the territories. The appearance of the Geographic Information Systems has offered a new variety of methods and tools that according with the strong urban growth, has helped to improve the planning culture reducing the duration of its analyzing processes, the data acquisition, and mainly the decision making. In that order, this paper set up some of the application methods of GIS in Urban Planning, based on the deep relation that exist between the basic components of the first and the work methodologies of the second one, and using examples about some of the practical uses that may have this new technology at the urbanism field.KeywordsUrban Planning, Urbanism, Spatial Relations, Territory.

AbstractAlthough the use of Geographic Information Systems (GIS) has a long history in archaeology, spatial technologies have been rarely used to analyse the content of textual collections. A newly developed approach termed Geographic Text Analysis (GTA) is now allowing the semi-automated exploration of large corpora incorporating a combination of Natural Language Processing techniques, Corpus Linguistics, and GIS. In this article we explain the development of GTA, propose possible uses of this methodology in the field of archaeology, and give a summary of the challenges that emerge from this type of analysis.
