Abstract:
Assigning geographical meta-information to textual pieces of information in an automatic way is a challenging semantic processing task that has been getting increasing attention from application and research areas that need to exploit this kind of information. With that in mind, in this paper, we propose a novel ontology-based framework for correctly identifying geographical entity references within texts and mapping them to corresponding ontological uris, as well as determining the geographical scope of texts, namely the areas and regions to which the texts are geographically elevant. Unlike other approaches which utilize only geographical information for performing these tasks, our approach allows the exploitation of any kind of semantic information that is explicitly or implicitly related to geographical entities in the given domain and application scenario. This exploitation, according to our experiments, manages to substantially improve the effectiveness of the geographical entity and scope resolution tasks, especially in scenarios where explicit geographical information is scarce.
