Evaluation of georeferencing

Abstract: In this paper we describe a georeferencing system which first uses Information Extraction techniques to identify place names in textual documents and which then resolves the place names against a choice of gazetteers. We have used the system to georeference three digitised historical collections and have evaluated its performance against human annotated gold standard samples from the three collections. We have also evaluated its performance on the SpatialML corpus which is a geo-annotated corpus of newspaper t… Show more

“…The Edinburgh Parser Tobin et al 2010) is an end-to-end system, developed in-house and partitioned into two subsystems, a geotagger and a geocoder. The geotagger is a multistep rule-based NER which makes use of lists of place names and person names for personal and location entity recognition.…”

“…Note that we see geoparsing as the task of location-based extraction from text (NER), and gecoding as the NED complement, the mapping of references to real-world counterparts [17]. Similar to current NER approaches, we can identify three different branches of methods [4]: Gazetteer-based lookup methods [18], Rule-based approaches (e.g. GATEs ANNIE module [19]) by using a set of symbolic rules to encode the decision procedure (Definite Clause Grammars via Prolog) [20].…”

“…Clough [4] and Tobin [5] reported their geo-referencing systems which firstly used information extraction techniques to identify place names in textual documents and to resolve the place names against gazetteers. This approach is simple and allows efficient implementations, however, with a loss of precision in toponym extraction.…”
