Towards Focused Plan Monitoring: A Technique and an Application to Mobile Robots

Until recently, techniques for AI plan generation relied on highly restrictive assumptions that were almost always violated in real-world environments; consequently, robot designers adopted reactive architectures and avoided AI planning techniques. Some recent research efforts have focused on obviating such assumptions by developing techniques that enable the generation and execution of plans in dynamic, uncertain environments. In this paper, we discuss one such technique, rationale-based monitoring, originally introduced by Veloso, Pollack, and Cox (Proceedings for the Fourth International Conference on AI Planning Systems, Pittsburgh, PA, 1998, pp. 171–179) and we describe our use of it in a simple mobile robot environment. We review the original approach, describe how it can be adapted for a causal-link planner, and provide experimental results demonstrating that it can lead to improved plans without consuming excessive overhead. We also describe our use of rationale-based monitoring in a mobile robot office-assistant project currently in progress.     

表格文件图象逻辑结构提取方法

近几年来,国内外已提出了许多关于表格文件图象分析的方法,但其中关于表格逻辑结构提取物方法却很少,为此,提出了一种关于表格文件逻辑结构撮的方法,此方法主要分为整表的全局划分、局部的逻辑结构分析和整表的再次全局划分３个步骤,该方法强调对文件全局和局部布局结构的综合分析,与以往的仅仅从局部上对表格逻辑结构进行了确定的方法相比,它具有较高的识别正确率,并可以识别结构更为复杂的表格文件。     

办公网络的设备选择与维护

计算机网络技术的飞速发展,计算机网络的应用也越来越多,促使很多企业也开始扩展网络办公及其他网络业务,那么网络设备的选择与维护便成为他们最关心的问题。     

办公自动化网络的组建与管理

本文以某办公自动化网络系统建设为例,详细阐述了综合布线系统设计、内部外部网络设计、网络管理和网络安全设计方面的主要工作,设计从综合布线开始,其中既有交换设备的选型,也有服务器及操作系统的选型,又有网络安全的管理措施,将理论知识与实践相结合,取得了显著的成效。     

WWW业务访问特性分布研究

WWW业务表现为一系列的访问序列。而Web Server和Proxy Server的日志很好地记录了这种访问序列的过程及特性。WWW业务的特性研究是Web Server、Web中间件研究和人工合成Web负载的基础。分析了一个Web Server和两个Proxy Server的日志,重点研究了Web页面请求的概率分布、Web静态文档大小的概率分布（含传输文档）、Web静态文档的访问距离的概率分布,并将分析结果同相关文献的结果进行了对比,同时通过试验证实了在使用Size作为Web缓存替换依据时,还应该考虑Web文档的访问频率。     

基于自然语言语义分析的Internet文件分类与过滤

网上文件过滤是网络信息安全研究的重要课题。传统的过滤方法简单地把关键字匹配作为分类的依据,常导致漏判误判等问题。文中提出一种基于自然语言理解的语义模板算法解决网上文件分类过滤的问题。实验结果表明该方法漏判误判率较低,是一种行之有效文件分类方法。     

Ontology-driven document enrichment: principles, tools and applications

In this paper, we present an approach to document enrichment, which consists of developing and integrating formal knowledge models with archives of documents, to provide intelligent knowledge retrieval and (possibly) additional knowledge-intensive services, beyond what is currently available using “standard” information retrieval and search facilities. Our approach is ontology-driven, in the sense that the construction of the knowledge model is carried out in a top-down fashion, by populating a given ontology, rather than in a bottom-up fashion, by annotating a particular document. In this paper, we give an overview of the approach and we examine the various types of issues (e.g. modelling, organizational and user interface issues) which need to be tackled to effectively deploy our approach in the workplace. In addition, we also discuss a number of technologies we have developed to support ontology-driven document enrichment and we illustrate our ideas in the domains of electronic news publishing, scholarly discourse and medical guidelines.     

A Scalable Toolkit for Designing Multimedia Authoring Environments

This paper introduces Kaomi, a scalable toolkit for designing authoring environments of multimedia documents. The underlying concept is to provide the designer of multimedia applications with a fast method to get an authoring system based on a set of synchronized views (the presentation view for displaying the document, the scenario view for showing the temporal organization of the document, ...) so that each view is the support of editing actions. Kaomi is flexible enough to support a variety of multimedia documents declarative formats. It is indeed a scalable toolkit since it provides facilities for extending and/or for modifying the resulting authoring environment. In addition, cross-platform portability is provided which allows operation in the heterogenous Internet environment. The use of Kaomi is mainly described through the design of two authoring environments: one for authoring a sub-set of the Smil standard of the W3C and the other one for Madeus, a constraint based multimedia language.
