Extracción automática de referencias geoespaciales en discurso libre usando técnicas de procesamiento de lenguaje natural y teoría de la accesibilidad

Abstract

La extracción automática de información geoespacial en tiempo real, a partir de discurso libre, tendrá un enorme impacto en tecnologías disruptivas, tales como los asistentes inteligentes y los motores de búsqueda. Generar modelos capaces de decodificar el discurso para luego transformarlo en datos estructurados aborda la solución de problemas como: la identificación automática de frases que se refieran a alguna entidad geoespacial; el manejo de sinónimos referidos a una misma locación (ambiguedad); la caracterización taxonómica de expresiones locativas; así como la automatización de procesos complejos de interpretación del lenguaje para la determinación de coordenadas geográficas en mapas y bases de datos. El proyecto presentado tiene por objetivo la automatización de procesos de georeferencia de documentos digitales para extraer conocimiento. La propuesta metodológica incluye compilación de un corpus, caracterización lingüística y desarrollo de algoritmos.

The automatic extraction of geospatial information in real time, from free speech, will an important impact on disruptive technologies, such as AI assistants and search engines. Models capable of decoding discourse and then transforming it into structured data addresses the solution of challenging problems such as: the automatic identification of phrases refering geospatial entities; the handling of synonyms referring to the same location (ambiguity); the taxonomic characterization of locative expressions; as well as the automation of complex processes of natural language interpretation to determine of geographical coordinates, maps and databases. The presented project aims to automate georeferencing processes of digital documents to extract georeferenced knowledge. The methodological proposal includes compilation of a corpus, linguistic characterization and algorithms.
