How can voting mechanisms improve the robustness and generalizability of toponym disambiguation? [PDF]

International Journal of Applied Earth Observation and Geoinformation, 2023
Natural language texts, such as tweets and news, contain a vast amount of geospatial information, which can be extracted by first recognizing toponyms in texts (toponym recognition) and then identifying their geospatial representations (toponym ...

Toponym Extraction and Disambiguation from Text: A Survey [PDF]

JOIV: International Journal on Informatics Visualization
Toponym is an essential element of geospatial information. Traditionally, toponyms are collected in a gazetteer through field surveys that require significant resources, including labor, time, and money.

GeoBERTSegmenter: Word Segmentation of Chinese Texts in the Geoscience Domain Using the Improved BERT Model

Earth and Space Science, Volume 9, Issue 10, October 2022., 2022
Abstract Unlike English, there is no natural separator‐like gap between words in Chinese, which makes Chinese word segmentation (CWS) a difficult information processing problem. At present, geological texts contain a large number of unregistered geological terms, and the existing rule‐based methods and machine‐learning and deep learning algorithms ...

Event Geoparser with Pseudo-Location Entity Identification and Numerical Argument Extraction Implementation and Evaluation in Indonesian News Domain

ISPRS International Journal of Geo-Information, 2020
Geoparser is a fundamental component of a Geographic Information Retrieval (GIR) geoparser, which performs toponym recognition, disambiguation, and geographic coordinate resolution from unstructured text domain. However, geoparsing of news articles which

Adaptive Geoparsing Method for Toponym Recognition and Resolution in Unstructured Text

Remote Sensing, 2020
The automatic extraction of geospatial information is an important aspect of data mining. Computer systems capable of discovering geographic information from natural language involve a complex process called geoparsing, which includes two important tasks:

Text‐analysis reveals taxonomic and geographic disparities in animal pollination literature

Ecography, Volume 43, Issue 1, Page 44-59, January 2020., 2020
Ecological systematic reviews and meta‐analyses have significantly increased our understanding of global biodiversity decline. However, for some ecological groups, incomplete and biased datasets have hindered our ability to construct robust, predictive models. One such group consists of the animal pollinators.

From Topic Networks to Distributed Cognitive Maps: Zipfian Topic Universes in the Area of Volunteered Geographic Information

Complexity, Volume 2020, Issue 1, 2020., 2020
Are nearby places (e.g., cities) described by related words? In this article, we transfer this research question in the field of lexical encoding of geographic information onto the level of intertextuality. To this end, we explore Volunteered Geographic Information (VGI) to model texts addressing places at the level of cities or regions with the help ...

Spatial Context from Open and Online Processing (SCOOP): Geographic, Temporal, and Thematic Analysis of Online Information Sources

ISPRS International Journal of Geo-Information, 2017
The Internet is increasingly a source of data for geographic information systems, as more data becomes linked, available through application programing interfaces (APIs), and more tools become available for handling unstructured web data.

Places in Information Science

Journal of the Association for Information Science and Technology, Volume 70, Issue 11, Page 1173-1182, November 2019., 2019
Human spatial concepts, such as the concept of place, are not immediately translatable to the geometric foundations of spatial databases and information systems developed over the past 50 years. These systems typically rest on the concepts of objects and fields, both bound to coordinates, as two general paradigms of geographic representation. The match
