Tweet Geolocation

open access: yesProceedings of the 2017 ACM on Conference on Information and Knowledge Management, 2017
Which venue is a tweet posted from? We referred this as fine-grained geolocation. To solve this problem effectively, we develop novel techniques to exploit each posting user's content history. This is motivated by our finding that most users do not share their visitation history, but have ample content history from tweet posts.

City-Level IP Geolocation Algorithm Based on PoP Network Topology

open access: yesIEEE Access, 2018
The existing city-level IP geolocation algorithms determine the location of IP by delay measurement and landmark comparison, and thus, the geolocation ability of these algorithms is affected by the delay precision and the number of landmarks.

Geolocation, ethics, and HIV research [PDF]

open access: yesHealth and Technology, 2021
The HIV epidemic continues to disproportionally affect marginalized populations. Digital tools, including global positioning system and ecologic momentary assessment, have been studied as methods for improving data collection and interventions among HIV-affected communities.

Continuous Representation of Location for Geolocation and Lexical Dialectology using Mixture Density Networks

open access: yes, 2017
We propose a method for embedding two-dimensional locations in a continuous vector space using a neural network-based model incorporating mixtures of Gaussian distributions, presenting two model variants for text-based geolocation and lexical ...

A Fast, Three-Dimensional, Indirect Geolocation Method Using IAGM and DSM Data without GCPs for Spaceborne SAR Images

open access: yesSensors, 2019
To determine the geolocation of a pixel for spaceborne synthetic aperture radar (SAR) images, traditional indirect geolocation methods can cause great computational complexity. In this paper, a fast, three-dimensional, indirect geolocation method without

Earth Polychromatic Imaging Camera Geolocation; Strategies to Reduce Uncertainty

open access: yesFrontiers in Remote Sensing, 2021
Earth Polychromatic Imaging Camera occupies a unique point of view for an Earth imager by being located approximately 1.5 million km from the planet at Earth-Sun Lagrange point, L1. This creates a number of unique challenges in geolocation, some of which
