Description

Discovering in a text the geographic references it may contain, is a task that human readers perform using both their lexical and contextual knowledge. Using a gazetteer to label such targeted references in a dataset, this paper proposes an approach to learning the context in which they appear and by this means extending the prior knowledge encoded in the gazetteer. The present work was carried in the particular framework of a system for disease outbreak alerts detection and geo-indexing.
