Fire tracking is an increasingly important area of research aiming to help firefighters more effectively fight fires. In the past, piloted aircraft have been the main source for obtaining fire characteristics from the air. In recent years unmanned air vehicles (UAVs) have become popular for the same purpose. While large UAVs are an effective means of assisting firefighters, they are expensive t...

A highly accurate client-independent geolocation service stands to be an important goal for the Internet. Despite an extensive research effort and significant advances in this area, this goal has not yet been met. Motivated by the fact that the best results to date are achieved by utilizing additional ’hints’ beyond inherently inaccurate delay-based measurements, we propose a novel geolocation ...

To maximise spectrum access opportunities for white space devices, incorporating real-time spectrum sensing with geolocation database is a promising approach to enhance detection resolution with reduced computation complexity. Advanced spectrum sensing techniques are needed to quickly and accurately identify spectrum occupancy over a wide frequency range. However, the stringent requirements fro...

A major challenge facing all law-enforcement and intelligence-gathering organizations is accurately and efficiently analyzing the growing volumes of crime data. Cybercrime refers to any crime that involves a computer and network, where computer may or may not play an instrumental part in the commission of the crime. Detection and investigation of cybercrime can likewise be difficult because bus...

Extracting useful information from social networks raises several challenges that still represent open research issues. In this paper we focus on the problem of extracting geolocated images from Tweets to support emergency response. A Tweet analysis process is discussed, focusing on the selection of posts, their geolocation based on their text content, and the subsequent analysis of the images ...

In this paper, we describe CSIRO Data61’s participation in the Geolocation shared task at the Workshop for Noisy User-generated Text. Our approach was to use ensemble methods to capitalise on four component methods: heuristics based on metadata, a label propagation method, timezone text classifiers, and an information retrieval approach. The ensembles we explored focused on examining the role o...
