Georeferencing Non-Gazetteered Place Names using Biological Specimen Records
A study from the Allan Herbarium (New Zealand) identifies place names in biological specimen records that are absent from current gazetteers, termed non-gazetteer place names (NGPs). The study georeferences NGPs using repeated occurrences across specimen records with spatial relation terms, implementing deterministic, probabilistic, and LLM-based methods for comparative analysis.

Biological specimen records from natural history institutions contain temporal geographic knowledge. Using digitized data from the Allan Herbarium in New Zealand, the study identifies place names in locality descriptions that are not in current gazetteers, calling them non-gazetteer place names (NGPs). These are often historical or vernacular. The researchers georeference NGPs by leveraging repeated occurrences of the same place name across records with different specimen locations and spatial relation terms, extracting and inverting these relations to derive constraints. They instantiate deterministic, probabilistic, and LLM-based methods and compare their strengths and limitations for text-based spatial inference. The study demonstrates a novel approach to recovering geographic information from historical records.
The study introduces a method for georeferencing place names absent from gazetteers by using repeated co-occurrences and spatial relation terms in text. It compares deterministic, probabilistic, and LLM-based approaches, suggesting that LLMs may offer advantages in handling linguistic variability. The next signal would be the release of benchmark datasets or open-source implementations for evaluating such methods.
This research highlights the potential of LLMs for spatial inference from unstructured text, which could extend to other domains like historical document analysis or geospatial data enrichment. The comparative analysis provides insights into when LLMs outperform traditional methods, influencing tool selection for geospatial tasks.
For companies in biodiversity informatics or geospatial services, this method could automate the enrichment of gazetteers, reducing manual effort. It also demonstrates a use case for LLMs in niche scientific domains, potentially opening new markets for AI-powered data curation tools.
Future work may involve scaling these methods to larger datasets and integrating them into digital humanities or biodiversity informatics pipelines. The approach could also be adapted for other types of spatial relation extraction, potentially leading to automated gazetteer expansion.
