A pragmatic guide to geoparsing evaluation: Toponyms, Named Entity Recognition and pragmatics. [PDF]

Lang Resour Eval, 2020
AbstractEmpirical methods in geoparsing have thus far lacked a standard evaluation framework describing the task, metrics and data used to compare state-of-the-art systems. Evaluation is further made inconsistent, even unrepresentative of real world usage by the lack of distinction between thedifferent types of toponyms, which necessitates new ...

Dealing with heterogeneous big data when geoparsing historical corpora

2014 IEEE International Conference on Big Data (Big Data), 2014
It has long been known that ‘variety’ is one of the key challenges and opportunities of big data. This is especially true when we consider the variety of content in historical corpora resulting from large-scale digitisation activities.

Geographical and linguistic perspectives on developing geoparsers with generic resources

International Journal of Geographical Information Science
Geoparsers aim to find place names in unstructured texts and locate them geographically. This process produces georeferenced data usable for spatial analyses or visualisations.

Extracting locations from sport and exercise-related social media messages using a neural network-based bilingual toponym recognition model

Journal of Spatial Information Science, 2022
Sport and exercise contribute to health and well-being in cities. While previous research has mainly focused on activities at specific locations such as sport facilities, "informal sport" that occur at arbitrary locations across the city have been ...

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.
