Résumé (en anglais)
An understanding of spatial information in natural language is necessary for many computational linguistics and artiﬁcial intelligence applications. In this paper, we discuss what problems researchers face with respect to this topic, focusing on the need for a well-developed annotation scheme. The desiderata for such a speciﬁcation language are deﬁned along with what representational mechanisms are required for the speciﬁcation to be successful. We then review several spatial information annotation schemes, focusing on the latest version of the ISO-Space speciﬁcation. Finally, we discuss where ISO-Space still falls short and propose some ways that the speciﬁcation could be enriched.
