Many data mining techniques have been proposed for mining useful patterns in text documents. However, how to effectively use and update discovered patterns is still an open research issue, especially in the domain of text mining. Since most existing text mining methods adopted term-based approaches, they all suffer from the problems of polysemy and synonymy. […]
BibPro: A Citation Parser Based on Sequence Alignment
Dramatic increase in the number of academic publications has led to growing demand for efficient organization of the resources to meet researchers’ needs. As a result, a number of network services have compiled databases from the public resources scattered over the Internet. However, publications by different conferences and journals adopt different citation styles. It is […]
Falcons Concept Search: A Practical Search Engine for Web Ontologies
Web ontologies provide shared concepts for describing domain entities and thus enable semantic interoperability between applications. To facilitate concept sharing and ontology reusing, we developed Falcons Concept Search, a novel keyword-based ontology search engine. In this paper, we illustrate how the proposed mode of interaction helps users quickly find ontologies that satisfy their needs and […]
Predictable High-Performance Computing Using Feedback Control and Admission Control
Historically, batch scheduling has dominated the management of High-Performance Computing (HPC) resources. One of the most significant limitations using this approach is an inability to predict both the start time and end time of jobs. Although existing researches such as resource reservation and queue-time prediction partially address this issue, a more predictable HPC system is […]
Stability-Optimal Grouping Strategy of Peer-to-Peer System
When applied in high-churn Internet environments, P2P systems face a dilemma: although most participants are too unstable, a P2P system requires sufficient stable peers to provide satisfactory core services. Thus, determining how to leverage unstable nodes seems to be the only choice. Our primary idea is to group unstable nodes together in order to form […]
Maximizing the Number of Broadcast Operations in Random Geometric Ad Hoc Wireless Networks
We consider static ad hoc wireless networks whose nodes, equipped with the same initial battery charge, may dynamically change their transmission range. When a node v transmits with range r(v), its battery charge is decreased by β r(v)2, where β > 0 is a fixed constant. The goal is to provide a range assignment schedule […]
Yet Another Simple Solution for the Concurrent Programming Control Problem
As multicore processors are becoming increasingly common everywhere, the future computing systems and devices are becoming inevitably concurrent. Also, on the applications side, automation is steadily infiltrating into everyday life, and hence, most software systems are becoming increasingly complex and concurrent. As a result, recent developments and projections indicate that we are entering into the […]
Energy-Efficient Opportunistic Routing in Wireless Sensor Networks
Opportunistic routing, has been shown to improve the network throughput, by allowing nodes that overhear the transmission and closer to the destination to participate in forwarding packets, i.e., in forwarder list. The nodes in forwarder list are prioritized and the lower priority forwarder will discard the packet if the packet has been forwarded by a […]
Node Reclamation and Replacement for Long-Lived Sensor Networks
When deployed for long-term tasks, the energy required to support sensor nodes’ activities is far more than the energy that can be preloaded in their batteries. No matter how the battery energy is conserved, once the energy is used up, the network life terminates. Therefore, guaranteeing long-term energy supply has persisted as a big challenge. […]
Effective Delay-Controlled Load Distribution over Multipath Networks
Owing to the heterogeneity and high degree of connectivity of various networks, there likely exist multiple available paths between a source and a destination. An effective model of delay-controlled load distribution becomes essential to efficiently utilize such parallel paths for multimedia data transmission and real-time applications, which are commonly known to be sensitive to packet […]
