Text2Geo : des données textuelles aux informations géospatiales

Abstract : We focus on the evaluation of methods for extracting spatial information from texts. After describing the study and analyzing all possibles forms of textual description of space and all the conventions adopted for the manual annotation of named entities of Location and Organization types, we propose to develop a hybrid method. This method combines information extraction approach based on patterns, with a supervised classification approach, to explore the context. We then discuss the different results obtained on the dataset of the Thau lagoon.
