SPERG: Scalable Political Event Report Geoparsing in Big Data
2018 IEEE International Conference on Intelligence and Security Informatics (ISI), 2018Digital newspaper archives accumulated over the last few decades serve as an easily accessible, rich source of information for researchers to conduct analytic studies. Extracting unambiguous geographic identifiers, such as the geographic coordinates solely from text descriptions, a process also known as geoparsing, has proven to be a major challenge ...

In this paper we present preliminary results for a pattern-based approach to parse web-based queries. The approach is designed to identify and categorize queries that include a geographical reference. Due to the ungrammaticality, multilinguality and ambiguity of the language in the 800,000 web-based queries in the collection, we started by building a ...

GeoTxt: A scalable geoparsing system for unstructured text geolocation
Transactions in GIS, 2019AbstractIn this article we present GeoTxt, a scalable geoparsing system for the recognition and geolocation of place names in unstructured text. GeoTxt offers six named entity recognition (NER) algorithms for place name recognition, and utilizes an enterprise search engine for the indexing, ranking, and retrieval of toponyms, enabling scalable ...

Dealing with heterogeneous big data when geoparsing historical corpora
2014 IEEE International Conference on Big Data (Big Data), 2014It 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. Collections such as Early English Books Online (EEBO) and the British Library 19th Century Newspapers are extremely ...

Geoparsing and geocoding places in a dynamic space context
2019The backbone of the proposal in this chapter is an automatic parser and a formal encoder of information describing places, spatial and verbal relations in textual documents in order to reconstruct and map the textually described itinerary. These tools allow us to show how to combine the information expressed in French texts, referring to places ...

Die Leistungsfähigkeit großer open source Sprachmodelle für Geoparsing-Aufgaben
Geoparsing ist ein Prozess, der Name Entity Recognition (NER) und Geocoding kombiniert, um Freitext zu verarbeiten und in ihnen geolokalisierte Begriffe zu identifizieren, die dann mit Geocoder API in in räumliche Koordinaten umgewandelt werden. Das Forschungsprojekt erfolgt im Rahmen einer Kooperation mit dem Landesbetrieb Immobilienmanagement und ...openaire +1 more source
