Swoop: A Web Ontology Editing Browser 总被引:2,自引:0,他引:2

In this paper, we describe Swoop, a hypermedia inspired Ontology Browser and Editor based on OWL, the recently standardized Web-oriented ontology language. After discussing the design rationale and architecture of Swoop, we focus mainly on its features, using illustrative examples to highlight its use. We demonstrate that with its Web-metaphor, adherence to OWL recommendations and key unique features, such as Collaborative Annotation using Annotea, Swoop acts as a useful and efficient Web Ontology development tool. We conclude with a list of future plans for Swoop, that should further increase its overall appeal and accessibility. 相似文献

In real world, the automatic detection of liver disease is a challenging problem among medical practitioners. The intent of this work is to propose an intelligent hybrid approach for the diagnosis of hepatitis disease. The diagnosis is performed with the combination of k‐means clustering and improved ensemble‐driven learning. To avoid clinical experience and to reduce the evaluation time, ensemble learning is deployed, which constructs a set of hypotheses by using multiple learners to solve a liver disease problem. The performance analysis of the proposed integrated hybrid system is compared in terms of accuracy, true positive rate, precision, f‐measure, kappa statistic, mean absolute error, and root mean squared error. Simulation results showed that the enhanced k‐means clustering and improved ensemble learning with enhanced adaptive boosting, bagged decision tree, and J48 decision tree‐based intelligent hybrid approach achieved better prediction outcomes than other existing individual and integrated methods. 相似文献

Drilling is a most important and crucial operation in the excavation industries.With the objective of looking into the enhancement of diamond drilling performance detailed laboratory investigations were carried out on phosphate rock.The effect of Poly (Ethylene Oxide) (PEO) added to the drilling water was studied by varying machine parameters and PEO concentration.The responses were rate of penetration and torque at the bit rock interface.Slake durability tests were also performed to understand the slaking behavior of phosphate rock in PEO solutions. 相似文献

Dense (~97%) CaO-stabilized ZrO2 ceramic was stabilized with minimum (3 mol%) doping (reported to date) and processed via conventional sintering at a low temperature (~1200°C); compositional analysis via X-ray florescence confirmed the CaO doping accuracy. Phase-pure tetragonal structure (characterized via both X-ray diffraction and Raman spectroscopy) along with uniform nanograins (90 nm) of the ceramic ensured the evolution of no monoclinic phase even after vigorous low-temperature degradation experiments (both thermal and hydrothermal aging for 80-100 h). The sintered ceramic recorded a high hardness (~15 GPa); the indentation toughness value was also comparable to a 3 mol% yttria-stabilized zirconia system. The remarkable structure–property correlations in the 3 mol% CaO-stabilized ZrO2 ceramic suggests that the same may be worth examining for suitable future applications (e.g., in dental ceramics). 相似文献

The pre-processing stage of finite element analysis of the Navier–Stokes equations is becoming increasingly important as the
desire for more general boundary conditions, as well as applications to parallel computers increases. The set up of general
boundary conditions and communication structures for parallel computations should be accomplished during the pre-processing
phase of the analysis, if possible, to ensure efficient computations for large scale problems in computational fluid dynamics.
This paper introduces a general methodology for geometry based boundary condition application and pre-computing of parallel
communication tasks.

To preserve client privacy in the data mining process, a variety of techniques based on random perturbation of individual
data records have been proposed recently. In this paper, we present FRAPP, a generalized matrix-theoretic framework of random
perturbation, which facilitates a systematic approach to the design of perturbation mechanisms for privacy-preserving mining.
Specifically, FRAPP is used to demonstrate that (a) the prior techniques differ only in their choices for the perturbation
matrix elements, and (b) a symmetric positive-definite perturbation matrix with minimal condition number can be identified,
substantially enhancing the accuracy even under strict privacy requirements. We also propose a novel perturbation mechanism
wherein the matrix elements are themselves characterized as random variables, and demonstrate that this feature provides significant
improvements in privacy at only a marginal reduction in accuracy. The quantitative utility of FRAPP, which is a general-purpose
random-perturbation-based privacy-preserving mining technique, is evaluated specifically with regard to association and classification
rule mining on a variety of real datasets. Our experimental results indicate that, for a given privacy requirement, either
substantially lower modeling errors are incurred as compared to the prior techniques, or the errors are comparable to those
of direct mining on the true database.

Perovskite light-emitting diodes (PeLEDs) are advancing because of their superior external quantum efficiencies (EQEs) and color purity. Still, additional work is needed for blue PeLEDs to achieve the same benchmarks as the other visible colors. This study demonstrates an extremely efficient blue PeLED with a 488 nm peak emission, a maximum luminance of 8600 cd m−2, and a maximum EQE of 12.2% by incorporating the double-sided ethane-1,2-diammonium bromide (EDBr2) ligand salt along with the long-chain ligand methylphenylammonium chloride (MeCl). The EDBr2 successfully improves the interaction between 2D perovskite layers by reducing the weak van der Waals interaction and creating a Dion–Jacobson (DJ) structure. Whereas the pristine sample (without EDBr2) is inhibited by small stacking number (n) 2D phases with nonradiative recombination regions that diminish the PeLED performance, adding EDBr2 successfully enables better energy transfer from small n phases to larger n phases. As evidenced by photoluminescence (PL), scanning electron microscopy (SEM), and atomic force microscopy (AFM) characterization, EDBr2 improves the morphology by reduction of pinholes and passivation of defects, subsequently improving the efficiencies and operational lifetimes of quasi-2D blue PeLEDs. 相似文献
