Description: 本文用lucene和Heritrix构建了一个Web 搜索应用程序
Lucene 是基于 Java 的全文信息检索包，它目前是 Apache Jakarta 家族下面的一个开源项目。
Lucene很强大，但是，无论多么强大的搜索引擎工具，在其后台，都需要一样东西来支援它，那就是网络爬虫Spider。网络爬虫，又被称为蜘蛛Spider，或是网络机器人、BOT等，这些都无关紧要，最重要的是要认识到，由于爬虫的存在，才使得搜索引擎有了丰富的资源。
Heritrix是一个纯由Java开发的、开源的Web网络爬虫，用户可以使用它从网络上抓取想要的资源。它来自于www.archive.org。Heritrix最出色之处在于它的可扩展性，开发者可以扩展它的各个组件，来实现自己的抓取逻辑。-In this paper, lucene and Heritrix build a Web search application
Lucene is a Java-based full-text information retrieval package, it is now the Apache Jakarta family, following an open source project.
Lucene is very powerful, but, no matter how powerful search engine tool, in its background, we need something to support it, that is, Web crawler Spider. Web crawlers, also known as Spider Spider, or robot network, BOT, etc., which are insignificant, the most important thing is to recognize that, due to the presence of reptiles, which makes the search engine there are plenty of resources.
Heritrix is a pure Java developed by the, open source Web crawler, the user can use it to grab you want from the network resources. It comes from www.archive.org. Heritrix is that it is the best scalability, developers can extend its various components, to achieve their capture logic.

Description: 信息检索系统从最初的纯手工检索系统业已发展到现在的以信息技术为支撑的检索系统，在这一过程中，适应新的信息资源、信息技术这些检索环境，提高信息检索系统的查全率、查准率和系统响应时间是不变的主题，在众多文本中掌握最有效的信息始终是信息处理的一大目标。围绕向量空间模型设计了一个文本检索系统，介绍向量空间模型的基础上给出了基于它的信息检索系统的一般结构框架和各部分的功能，探讨了系统中所涉及到的关键技术。用向量空间模型进行特征表达，用TF-IDF(Term-Frequency Inverse-Document-Frequency)进行特征项赋权，用倒排文档进行索引，用余弦夹角进行距离度量，用查全率和查准率评价检索系统性能，并以向量空间模型及相关理论为基础对中文信息检索进行了一些探讨。向量空间模型需要解决特征项的生成和加权、相似度的计算（检索运算）等一系列问题。由于向量检索中采用的向量叫某种距离度量来反映文档的满足程度，所以相似度的值最好能与真实情况相符，计算简便。-Information retrieval system to retrieve from the first hand to the present system has been developed using information technology to support the retrieval system, in the process and adapt to new information resources, information technology, the search environment, improve information retrieval system recall , precision and system response time is the constant theme in many text information is always the most effective control is a major goal of information processing. Vector space model around a text retrieval system is designed to introduce the vector space model is given on the basis of its information retrieval system based on the general framework and functions of each part, of the system, the key technologies involved. The feature vector space model using the expression, with the TF-IDF (Term-Frequency Inverse-Document-Frequency) for feature items empowerment, with the inverted file indexing, with the cosine angle between the distance measurement, with recall and precision evalu Platform: |

Description: Two novel contributions to Content Based Image Retrieval are presented and
discussed. The fi rst is a search engine for font recognition. The intended usage
is the search in very large font databases. The input to the search engine is an
image of a text line, and the output is the name of the font used when printing
the text. After pre-processing and segmentation of the input image, a local
approach is used, where features are calculated for individual characters. The
method is based on eigenimages calculated from edge fi ltered character images,
which enables compact feature vectors that can be computed rapidly. A system
for visualizing the entire font database is also proposed. Applying geometry
preserving linear- and non-linear manifold learning methods, the structure of
the high-dimensional feature space is mapped to a two-dimensional representa-
tion, which can be reorganized into a grid-based display. Platform: |

Description: 最新的几篇图像检索方面的论文。在检索原理上，无论是基于文本的图像检索还是基于内容的图像检索，主要包括三方面：一方面对用户需求的分析和转化，形成可以检索索引数据库的提问；另一方面，收集和加工图像资源，提取特征，分析并进行标引，建立图像的索引数据库；最后一方面是根据相似度算法，计算用户提问与索引数据库中记录的相似度大小，提取出满足阈值的记录作为结果，按照相似度降序的方式输出。-The latest image retri several papers.
