An algorithm for local geoparsing of microtext
GeoInformatica, 2013The location of the author of a social media message is not invariably the same as the location that the author writes about in the message. In applications that mine these messages for information such as tracking news, political events or responding to disasters, it is the geographic content of the message rather than the location of the author that ...

Customising geoparsing and georeferencing for historical texts
2013 IEEE International Conference on Big Data, 2013In order to better support the text mining of historical texts, we propose a combination of complementary techniques from Geographical Information Systems, computational and corpus linguistics. In previous work, we have described this as `visual gisting' to extract important themes from text and locate those themes on a map representing geographical ...

Automated Disaster News Collection Classification and Geoparsing
SSRN Electronic Journal, 2021A disaster is an unforeseen event, which can have a tremendous impact on human life as well as on the environment. The Internet provides a lot of sources that generate huge amounts of news articles daily. With the increase in the number of online news articles, it has become difficult for users to access disaster relevant news, which makes it a ...

Use of the Edinburgh geoparser for georeferencing digitized historical collections
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010We report on two JISC-funded projects that aimed to enrich the metadata of digitized historical collections with georeferences and other information automatically computed using geoparsing and related information extraction technologies. Understanding location is a critical part of any historical research, and the nature of the collections makes them ...

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 ...

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 ...

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 ...
