The paper introduces a Web system which supports registration of scholarly papers to institutional repositories. Institutional repository is an important service for academic societies, however the number of archived papers is not enough in most of institutions. The authors of the paper developed a system that supports authors of papers (that is, researchers) and managers of repositories in registration of papers. By connecting with external databases of published research papers, the system urges researchers register their papers to repository. Additionally, the system automatically searches the copyright policy for each paper also using external databases. This paper makes clear the problem of current institutional repositories, and then describes the detailed idea of the developed system as a solution. The system is expected to decrease the efforts of researchers and managers for paper registration, and increase the number of archived papers in institutional repositories thereby.
本文介绍了一个支持学术论文向机构知识库注册的Web系统。机构知识库是学术团体的一项重要服务,但大多数机构的论文归档数量不足。该论文的作者开发了一个系统,支持论文的作者(即研究人员)和存储库的管理人员进行论文注册。该系统通过与已发表论文的外部数据库连接,促使研究人员将论文注册到知识库。此外,系统还使用外部数据库自动检索每篇论文的版权政策。本文明确了当前机构知识库存在的问题,然后描述了开发系统作为解决方案的详细思想。预计该系统将减少研究人员和管理人员为论文登记所做的努力,从而增加机构资料库中的存档论文数量。

In recent years, with the development of the Internet, and the rapidly increasing number of tourism portal sites and blogs, we can obtain a variety of tourist information on the Internet. If we have a specific need, we can obtain the required information through checking the retrieved results one by one. However, in order to see the whole trend of the results, it is necessary to analyze and visualize the document group. In this paper, by storing a set of tourism-related future words in WordNet, which is a concept thesaurus, we proposed a method using information from WordNet to visualize a document group as a conceptual graph. With the structure of a thesaurus, this method enables us to understand the contents of document group at a glance. Furthermore, by comparing the thesaurus structures, which are obtained from different background document groups, we can grasp the differences.
近年来,随着互联网的发展,旅游门户网站和博客的数量迅速增加,我们可以在互联网上获取各种各样的旅游信息。如果我们有特定的需求,我们可以通过逐个检查检索结果来获得所需的信息。但是,为了看到结果的整体趋势,有必要对文档组进行分析和可视化。本文通过在概念词库WordNet中存储一组旅游相关的未来词,提出了一种利用WordNet中的信息将文档组可视化为概念图的方法。该方法采用同义词典的结构,使我们能够一目了然地了解文档组的内容。此外,通过比较不同背景文档组获得的词库结构,我们可以掌握其中的差异。

We are developing a concept dictionary for Petit Trips (Short Time Trips). Based on the concept dictionary, we propose a smart phone-based system to support the Petit Trips. This system provides travelers a Classification Network of tourist spots according to their locations. While travelers select their preferred tourist spots, the system will recommend the suitable tourist spots which have similar features. Through the Classification Network of tourist spots, travelers can go to their preferred tourist spots one after another.

Supply chain management (SCM) is a promising management strategy in enterprises for knowledge management, electronic (e-) business and commerce. In the supply chain process, the initial product planning and design stages play a crucial role in saving money and time in the production process. In particular, innovative design for improving a product makes enterprises more competitive. Innovation can be enhanced by constructing the information infrastructure to consider four attributes of the product: cost, quality, function and technology [10]. Extracting innovative design considerations for a product from the information infrastructure requires large knowledge bases and solutions to technical contradictions. The theory of inventive problem solving (TRIZ) supports designers for innovative product design, but can require machine searching of large databases. We describe the construction of the TRIZ ontology and its application to the information infrastructure for product design in the SCM process. We show that TRIZ can automatically treat and share enormous amounts of information through its ontology. We can therefore deduce and suggest versatile alternatives to produce innovative products in the SCM process. This may open up new possibilities to design innovative products.
供应链管理(SCM)是企业知识管理、电子商务和电子商务的一种很有前途的管理策略。在供应链过程中,最初的产品规划和设计阶段对于节省生产过程中的资金和时间起着至关重要的作用。特别是为改进产品而进行的创新设计,使企业更具竞争力。通过构建信息基础设施来考虑产品的四个属性:成本、质量、功能和技术bbb,可以增强创新能力。从信息基础设施中提取产品的创新设计注意事项需要大量的知识基础和技术矛盾的解决方案。创造性问题解决理论(TRIZ)支持设计师进行创新产品设计,但可能需要大型数据库的机器搜索。介绍了TRIZ本体的构建及其在供应链管理过程中产品设计信息基础设施中的应用。我们展示了TRIZ可以通过它的本体自动处理和共享大量的信息。因此,我们可以推断并建议在供应链管理过程中生产创新产品的多种替代方案。这可能为设计创新产品开辟新的可能性。

Based on rough set reduction artificial immune system, a new method for fault diagnosis of analog circuit is proposed. The proposed method uses wavelet to analysis the output voltage as the fault examples. Then the examples are reduced through attributes reduction to obtain a smaller set of all examples. And the new samples are trained to get the optimal cluster center of each fault. Finally, the fault component is located by comparing the distance between the test samples and the optimal cluster centers. The simulation result shows that the proposed method has high accuracy in diagnosis of tolerance analog circuits, and higher speed than pure artificial immune system.

A lot of information concerning the status of companies are available on the Web. However, a simple search of documents does not explain the meaning or the cause the status. Semantical interpretation and hypotheses generation are necessary for further analysis. This paper proposes a method to analyse the cause and the situation of bankruptcy with respect to particular condition that a user can specify as a query. The method is based on the theory of formal concept analysis. The novelty of the method is in (a) that sentences are considered as objects and words are considered as attributes and (b) that a concise subgraph of the concept lattice is introduced and used to guess the cause. Two cases of interactive and iterative process are shown where a user proceeds from a simple query to a new hypothesis, which would not be able to found by a naive cross tabulation or keyword extraction.
很多关于公司状况的信息都可以在网上找到。然而,简单地搜索文件并不能解释这种状态的含义或原因。语义解释和假设生成是进一步分析的必要条件。本文提出了一种针对用户可以指定查询的特定条件来分析破产原因和破产情况的方法。该方法以形式概念分析理论为基础。该方法的新颖之处在于:(a)将句子视为对象,将单词视为属性;(b)引入概念格的简明子图并使用其来猜测原因。显示了交互和迭代过程的两个案例,其中用户从一个简单的查询继续到一个新的假设,这将无法通过简单的交叉制表或关键字提取找到。

Uncovering perceptual awareness of visual stimulus with adaptive multiscale entropy 利用自适应多尺度熵揭示视觉刺激的感知意识
Pub Date : 2011-09-01 DOI: 10.1109/ICAWST.2011.6163177

To probe the perceptual awareness of a visual stimulus, we use the paradigm of generalized flash suppression (GFS) to dissociate physical stimulation from perceptual experience. This perceptual suppression approach has previously been used to investigate perceptual visibility correlates in visual cortex, mainly with linear methods, such as spectral analysis. While meaningful, the linear method alone may be insufficient for the full assessment of neural dynamics due to the fundamentally nonlinear nature of neural signal. In this contribution, we set forth to analyze local field potential (LFP) data collected from the multiple visual areas in V1, V2 and V4 of a macaque monkey while performing the GFS task using nonlinear method - adaptive multiscale entropy (AME) - to study the neural dynamics of perceptual suppression. We also propose a new cross-entropy measure at multiple scales, namely adaptive multiscale cross-entropy (AMCE), to assess the nonlinear interdependency between cortical areas. We show that: (1) multiscale entropy exhibits perception-related changes in all three areas, with higher entropy (i.e. higher complexity) observed during perceptual suppression; (2) the magnitude of the perception-related entropy changes increases systematically over successive hierarchical stages (i.e. from lower areas V1 to V2, up to higher area V4); and (3) cross-entropy between any two cortical areas reveals higher degree of asynchrony or dissimilarity during perceptual suppression, indicating decreased neuronal interdependency between areas. Our findings demonstrate that the adaptive multiscale entropy is a sensitive measure of perceptual visibility, and thus can be used to uncover perceptual awareness of a stimulus.
为了探究视觉刺激的知觉意识,我们使用广义闪光抑制(GFS)范式将物理刺激与知觉经验分离开来。这种知觉抑制方法以前被用于研究视觉皮层的知觉可见性相关性,主要是线性方法,如光谱分析。虽然有意义,但由于神经信号的非线性本质,单独的线性方法可能不足以全面评估神经动力学。本文采用非线性自适应多尺度熵(AME)方法,对猕猴在执行GFS任务时从V1、V2和V4多个视觉区域采集的局部场电位(LFP)数据进行分析,研究感知抑制的神经动力学。我们还提出了一种新的多尺度交叉熵度量,即自适应多尺度交叉熵(AMCE),以评估皮质区域之间的非线性相互依赖性。研究表明:(1)多尺度熵在三个区域都表现出感知相关的变化,在感知抑制期间观察到更高的熵(即更高的复杂性);(2)感知相关熵的变化幅度在连续的层次阶段(即从较低的区域V1到V2,再到较高的区域V4)呈系统增加;(3)在知觉抑制过程中,任意两个皮质区域间的交叉熵显示出较高程度的不同步或不相似,表明区域间神经元的相互依赖性降低。我们的研究结果表明,自适应多尺度熵是感知可见性的敏感度量,因此可以用来揭示刺激的感知意识。

Blind source separation based on the support recovery of pilot-signals 基于导频信号支持恢复的盲源分离

Blind source separation (BSS) has been widely discussed since it has many real applications. Recently, under the assumption that mixing matrix is orthogonal and source signals are sparse, Mishali et al. developed an amazing BSS method by using the support recovery of sources and the singular value decomposition (SVD). However, the performance of the algorithm is not as good as expected. In this paper, we present a novel BSS method that is performed by an identification of the mixing matrix by introducing the so-called pilot-signals. The pilot-signals are not required to be known, rather, they are required to have a known extent of sparsity. The method includes two phases, the mixing matrix estimation and the separation phases. The estimation phase is constructed with iterating of the three parts, support recovery, mixing matrix identification and pilot-signals recovery. The numerical experiments show that proposed method can efficiently converge and can recover the unknown source signals efficiently.
盲源分离(BSS)由于具有广泛的实际应用而受到广泛的讨论。最近,Mishali等人在混合矩阵正交、源信号稀疏的假设下,利用源的支持恢复和奇异值分解(SVD),提出了一种令人惊叹的BSS方法。然而,该算法的性能并没有预期的那么好。在本文中,我们提出了一种新的BSS方法,该方法通过引入所谓的导频信号来识别混合矩阵。不要求驾驶员信号是已知的,而是要求它们具有已知的稀疏度。该方法包括两个阶段,混合矩阵估计和分离阶段。估计阶段由支持恢复、混合矩阵识别和导频信号恢复三部分的迭代构成。数值实验表明,该方法能有效收敛,并能有效地恢复未知源信号。

The numerical experiments show that proposed method can efficiently converge and can recover the unknown source signals efficiently.","PeriodicalId":126169,"journal":{"name":"2011 3rd International Conference on Awareness Science and Technology (iCAST)","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116137677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, IPTV has become a convergent infrastructure for entertainment and communications services in our daily life. An IPTV set-top-box is now an important device in the Internet-of-things of each home. It is expected that this infrastructure would be suitable for emergency alert systems (EAS), especially in disaster and health-care scenarios. In this paper, we first review the recent developments to support emergency scenarios, including related IPTV standards and research in smart home. Then we propose an architecture for full-duplex emergency alert services based on IPTV platform. In order to maintain a very high availability of service, the key features of the architecture include the redundancy of devices and network connections and the scalability of data.
近年来,IPTV已经成为我们日常生活中娱乐和通信服务的融合基础设施。IPTV机顶盒现在是每个家庭物联网的重要设备。预计这种基础设施将适用于紧急警报系统,特别是在灾害和保健情况下。在本文中,我们首先回顾了支持应急场景的最新发展,包括相关的IPTV标准和智能家居的研究。在此基础上,提出了一种基于IPTV平台的全双工应急报警服务体系结构。为了保持非常高的服务可用性,该体系结构的关键特性包括设备和网络连接的冗余以及数据的可伸缩性。
