Architecture for Large Scale Reasoning in Business Intellige...

2012年计算机应用与系统建模国际会议

作者： xinlong zhang Bin Cao Yanming Ye College of Computer Science Zhejiang Universi College of Computer Science Zhejiang University

Business intelligence plays a crucial role in modern business. Nevertheless, present business intelligence is not in a position to provide comprehensive business advices owing to limitations on the scope of data and satisfy the indispensable timeliness for business activities. To address these problems, we propose an architecture for business intelligence which could reason on data from numerous domains and provide different users with disparate business advices and results. Furthermore, in our architecture, the production system used to reason depends on MapReduce programming model to implement production rule matching concurrently in different computers with the Rete algorithm. Adopting MapReduce programming model enables production system to obtain more impressive efficiency in rule matching, especially when it comes to a large-scale rules and facts. What’s more, we also adopt two conflict-resolving polices to decide in which sequence matched production rules are executed. In this paper, we firstly describe the architecture and then illustrate the particular implementation of this architecture.

傅斯年图书馆藏《文选楼丛书未刻稿本》十六册,未曾见学者讨论过。此稿本为阮元旧藏底稿,极有可能曾入况周颐之手,后辗转被耶稣会中华省获得,并最终入藏傅斯年图书馆。它包含《待刊书目》《待购书目》以及选录自前人笔记的经史考辨条目等几个部分,其中删改校对,皆是阮元亲笔,具有较重要的文献价值与学术价值,值得深入探讨。从《待刊书目》可知《文选楼丛书》原先有一个较为庞大的刊刻计划,后因遭遇变故而中辍,通过此目还可窥见阮元独特的文学史眼光及同现今文学史体系不同的诸多观念。两册《待购书目》不是同一时期所写,其成册当在道光二十五年之后,而且阮元罗列了不少女性著作和士人编纂的女性总集,这除了与当时女性文学繁荣的背景有关之外,与阮元自己对女性作家及女性著作的重视更有关系。

针对现有压缩域图像增强算法在提高图像对比度时,存在不能很好地增强图像细节及保持色彩信息的局限性,提出一种新的基于Retinex理论的DCT压缩域图像增强算法.该算法以Retinex理论为基础,将DCT系数分为入射分量(DC系数)和反射分量(AC系数),通过对DC系数进行动态范围调整,对AC系数进行细节增强调整,并使用阈值方法抑制块状效应,由此实现对压缩域图像的增强.实验结果表明,与传统的Retinex增强算法及DCT压缩域增强算法相比,该算法具有更好的细节增强及色彩保持效果,且能较好地抑制块状效应.

为更好模拟行人疏散过程中微观个体行为,考虑行人身材半径及在疏散过程中行人步行速度随运动状态变化,将社会力模型运行规则引入元胞自动机模型,建立了一种社会力模型计算步行速度、空间离散化程度和步行速度较高的疏散模型,用于模拟紧急情况下的行人疏散过程。在该模型中空间划分为更小网格,每个行人占用一到多个单元格,行人的身材半径不再不变,每个行人移动的距离由其速度决定,根据基于速度的出口选择方法和行人运动规律,通过数值模拟分析,研究了疏散过程中的动态性。研究表明基于速度的网格移动数量、行人数量、期望速度、行人身材半径、松弛时间等参数影响疏散效率,结合连续模型的优点能够更加客观真实刻画疏散过程,有助于离散模型描述行人疏散微观行为特征。
