Event Detection in Twitter
TLDR
This paper attempts to tackle the challenges of event detection in Twitter with EDCoW (Event Detection with Clustering of Wavelet-based Signals), which builds signals for individual words by applying wavelet analysis on the frequencybased raw signals of the words. Expand
A-STAR: A Mobile Ad Hoc Routing Strategy for Metropolis Vehicular Communications
TLDR
This paper proposes a new position-based routing scheme called Anchor-based Street and Traffic Aware Routing (A-STAR), designed specifically for IVCS in a city environment, and shows significant performance improvement in a comparative simulation study with other similar routing approaches. Expand
TwiNER: named entity recognition in targeted twitter stream
TLDR
A novel 2-step unsupervised NER system for targeted Twitter stream, called TwiNER, which leverages on the global context obtained from Wikipedia and Web N-Gram corpus to partition tweets into valid segments (phrases) using a dynamic programming algorithm. Expand
Optimization of Resource Provisioning Cost in Cloud Computing
TLDR
Numerical studies are extensively performed in which the results clearly show that with the OCRP algorithm, cloud consumer can successfully minimize total cost of resource provisioning in cloud computing environments. Expand
Position Based Opportunistic Routing for Robust Data Delivery in MANETs
TLDR
A novel protocol called Position based Opportunistic Routing (POR) is proposed which takes full advantage of the broadcast nature of wireless channel and opportunistic forwarding and yields excellent resilience in hostile environments. Expand
TrustCloud: A Framework for Accountability and Trust in Cloud Computing
TLDR
Key issues and challenges in achieving a trusted cloud through the use of detective controls are discussed, and the Trust Cloud framework is presented, which addresses accountability in cloud computing via technical and policy-based approaches. Expand
Optimal virtual machine placement across multiple cloud providers
TLDR
An optimal virtual machine placement (OVMP) algorithm can minimize the cost spending in each plan for hosting virtual machines in a multiple cloud provider environment under future demand and price uncertainty. Expand
A Routing Strategy for Metropolis Vehicular Communications
TLDR
This paper proposes a new position-based routing scheme called Anchor-based Street and Traffic Aware Routing (A-STAR), designed specifically for IVCS in a city environment, and shows significant performance improvement in a comparative simulation study with other similar routing approaches. Expand
Toward Reliable Data Delivery for Highly Dynamic Mobile Ad Hoc Networks
TLDR
Both theoretical analysis and simulation results show that POR achieves excellent performance even under high node mobility with acceptable overhead and the new void handling scheme also works well. Expand
Bottom-Up Saliency Detection Model Based on Human Visual Sensitivity and Amplitude Spectrum
TLDR
A new saliency detection model based on the human visual sensitivity and the amplitude spectrum of quaternion Fourier transform (QFT) to represent the color, intensity, and orientation distributions for image patches is proposed. Expand
