Mining Space-Time Elements of Opinion
2012 International Conference on Asian Language Processing, 2012This paper introduces a new opinion model using space-time elements. It proposes the concept of an Opinion Importance Factor which is composed of a Time Importance Factor and a Source Importance Factor. Based on that, it analyzes the characteristics of the Time Importance Factor in different applications and divides the Source Importance Factor into ...

Space efficient mining of multigraph streams
Proceedings of the twenty-fourth ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems, 2005The challenge of monitoring massive amounts of data generated by communication networks has led to the interest in data stream processing. We study streams of edges in massive communication multigraphs, defined by (source, destination) pairs. The goal is to compute properties of the underlying graph while using small space (much smaller than the number

The author stated that Hollywood movies have ensured we associate the word "asteroid" with the imminent destruction of the world. But these space rocks may yet prove useful as stepping stones to deep space exploration and a multi-billion dollar mining industry.

Mining Hubble Space Telescope images
2017 International Joint Conference on Neural Networks (IJCNN), 2017Astrophysicists rely on crowd sourced initiatives to classify galaxies in large surveys. The next generation of telescopes will lead to a revolutionary increase in the amount of unlabelled data available to astrophysicists making crowd sourcing infeasible. To cope with this significant increase in data astrophysicists will need unsupervised techniques.

SIGSPATIAL Special, 2010
There are numerous data mining applications working in metric spaces. In the following we will exemplarily sketch three main topics in this area: the impact of metric similarity functions on data mining, data mining in uncertain data and mining high-dimensional data.

Regulation of Safety of Space Mining and Its Implications for Space Safety
SSRN Electronic Journal, 2016We may soon have operational systems for robotic repair and refueling of satellites, solar power satellites, as well as increasingly sophisticated satellites for various types of defense and security operations. But something entirely new is also now on the horizon for space applications and instead of operation in Earth orbits these systems may seek ...

The Great Space Rush: Regulating Space Mining
SSRN Electronic Journal, 2020This article discusses why the existing international framework is not ready for an anticipated rush to exploit space resources. Nation State models cannot adequately deal with issues of giving trade-able rights to exploration areas, title to space resources and provide sufficient incentives and sanctions to prevent dangerous risk taking behavior. They

Abstract Constantia winds a long scarf around her neck. “How far is it to Rockefeller Center?” “A few blocks.” You pause. “Let’s continue our lessons. Today I want to talk about distances in spacetime. I want to tell you about spacetime intervals, Minkowskian space, and null intervals.” Stooping down, you motion to a little alley next to

Modelling and Mining of Networked Information Spaces
2008In recent years, the emergence of the Web and the dramatic increase in computing, storage and networking capacity has given rise to the concept of networked information spaces. The prime example of a networked information space is the World Wide Web itself.
