HeidelPlace: An Extensible Framework for Geoparsing [PDF]

Proceedings of the 2017 Conference on Empirical Methods in Natural Language Processing: System Demonstrations, 2017
Geographic information extraction from textual data sources, called geoparsing, is a key task in text processing and central to subsequent spatial analysis approaches. Several geoparsers are available that support this task, each with its own (often limited or specialized) gazetteer and its own approaches to toponym detection and resolution.

Reintroduction biology and the IUCN Red List: The dominance of species of Least Concern in the peer-reviewed literature

Global Ecology and Conservation, 2022
Reintroduction biology is a key tool for mitigating the catastrophic reduction in species’ ranges, caused by humans over the last 500 years. To assess where reintroduction biology scientific research is targeted, we used text-analysis methods to extract ...

How can voting mechanisms improve the robustness and generalizability of toponym disambiguation?

International Journal of Applied Earth Observations and Geoinformation, 2023
Natural language texts, such as tweets and news, contain a vast amount of geospatial information, which can be extracted by first recognizing toponyms in texts (toponym recognition) and then identifying their geospatial representations (toponym ...

Event Geoparser with Pseudo-Location Entity Identification and Numerical Argument Extraction Implementation and Evaluation in Indonesian News Domain

ISPRS International Journal of Geo-Information, 2020
Geoparser is a fundamental component of a Geographic Information Retrieval (GIR) geoparser, which performs toponym recognition, disambiguation, and geographic coordinate resolution from unstructured text domain. However, geoparsing of news articles which

Crisis Mapping during Natural Disasters via Text Analysis of Social Media Messages [PDF]

, 2015
Recent disasters demonstrated the central role of social media during emergencies thus motivating the exploitation of such data for crisis mapping. We propose a crisis mapping system that addresses limitations of current state-of-the-art approaches by ...

Adapting the Edinburgh Geoparser for Historical Georeferencing [PDF]

International Journal of Humanities and Arts Computing, 2015
Place name mentions in text may have more than one potential referent (e.g. Peru, the country vs. Peru, the city in Indiana). The Edinburgh Language Technology Group (LTG) has developed the Edinburgh Geoparser, a system that can automatically recognise place name mentions in text and disambiguate them with respect to a gazetteer.
