数据信息

Epistemologically speaking, information is made up of a collection of data and knowledge is made up of different strands of information.

从知识论而言，信息是数据的集合，而知识则是由不同的信息所组成。

However, these solutions are disadvantageous in cost and complexity of technology.In this thesis, SNMP innovatively applied into the management of Lon Works control network, by using Ethernet, Lon Works control network is integrated exoterically and seamlessly with information network in enterprises, distilling network information from LonWorks based on DDE technology, realizing the control and management to LonWorks based on SNMP.

本文创新地将SNMP协议引入到LonWorks控制网络的管理中，通过以太网将LonWorks控制网络与企业信息网络进行开放的、无缝的集成，采用动态数据交换技术完成了LonWorks现场信息的提取，利用SNMP协议实现了LonWorks现场网络的监控和管理。

The traditional recording mode with paper and pencils cant satisfiy the precision and speed of the modern data collection. With the development of Embedded system technology and GPS technology, that portable device is used in foresty resource data collection is changing the tranditional mode. Meanwhile, portable device with wireless communication has been become the important instrument to get the published information when forestry GIS based on web is used to publish infomation and monitor resource.

随着嵌入式技术、GPS技术的发展，手持设备开始应用在野外调查数据采集中；同时，基于Web的林业GIS作为森林资源的动态监测和信息发布技术的日益成熟，具有无线通讯功能的手持设备逐渐成为获得发布信息的移动客户端。

The dissertation focuses on the topics for automatic, accurate, and efficient metadata extraction from general and unstructured documents, on the basis of the state of the work on metadata extraction. After analyzing the limitations of current work, we propose a model for Automatic Document Metadata Extraction, and formulize the problem under the framework of statistical learning.

首先，论文针对目前元数据抽取在处理的文档对象和采用的抽取方法方面所存在的问题和不足，以统计学习理论和信息抽取领域相关研究为指导，结合非结构化文档的特点，提出了文档元数据自动抽取（Automatic Document Metadata Extraction，ADME）模型，给出其形式化描述，进而介绍模型工作机理和处理流程。

A new observability evaluation algorithm based on Factored Use-Def chains is provided. It represents data dependence information of Verilog RTL codes by FUD chains. Furthermore, it enhances capability of FUD chains, by usingφ-terms to track running behavior of programs.

提出了一种新的基于FUD链的可观测性评估算法，即，利用数据流分析中的FUD链来表征Verilog RTL代码的数据依赖信息，并拓展了原始FUD链的功能，使用其中的φ-term来追踪Verilog RTL代码动态执行的轨迹。

The Data Mining extracts knowledge that is not understood beforehand, but is useful to people from dataset which is massive, not incomplete, noise fuzzily, and stochastic.

数据挖掘就是从大量的、不完全的、有噪音的、模糊的、随机的数据中，提取隐含在其中的、人们事先不知道的、但又是潜在有用的信息和知识的过程。

Geographic Information System, an advanced technology, integratescomputer science, informatics, geography and others. It has been widely used innatural resource development, environmental protection, city planning, disastermonitoring and evaluation, etc. Capacity spectrum method is an approach of simplifying the structural dynamicanalysis.

地理信息系统是一门集计算机科学、信息学、地理学等多门科学为一体的新兴学科，由于其能快速、方便管理海量数据的特点，已被广泛应用于资源开发、环境保护、城市规划建设和灾害监测与评估等领域。

Nowadays with the wide use of technology of Internet, the problem of "adequate data and scarcity knowledge" has become increasingly distinct. Knowledge discovery study how to gain valuable knowledge and information intellectively and automatically from a mass of data, so it has been a very active studying field in artificial intelligent.

随着Internet技术的日益普及，&丰富的数据与贫乏的知识&问题变得日渐突出，而知识发现正是研究如何从大量的数据中智能地、自动地抽取出有价值的知识和信息，因而成为当前人工智能中非常活跃的研究领域。

In this model, hardware system, in which PLC is adopted as monitoring lower computers and computers are adopted as monitoring upper computers, collects and supervises various data of control room's environment of transformer substation and power device by various sensors installed on the spot, and the real-time data shows the running information of diverse transformer substations intuitionally and timely; Combination of computers and PLC fully utilizes each characteristics and advantages of computers and PLC, and enhances the stability of the whole system.

硬件系统采用PLC作为下位机，计算机作为上位机，通过现场安装的各种传感器对隧道变电所机房环境和动力设备等各种数据进行采集和监控，这些实时数据及时直观的反映了各个变电所各项运行信息。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
