自动索引

In this engine, the double-byte inverted index is employed to build an inverted index table with every double bytes of the file name, the automatic classification of query results is used to establish a tree structure of query results based on the search topic, and the automatic error correction is adopted to construct a spelling mistake dictionary with the high-frequency search keywords in user query logs.

双字节倒排是对文件名中每两个字节建立倒排索引表，自动分类是对检索结果按主题划分为层次结构，查询自动纠错是以用户查询日志中的高频查询词为数据源构建拼写错误词典。

Google Web search team infrastructure software engineers Ye Xie Er Bote and尼森哈扎伊 said:"Of course, we do not index these pages 1 trillion in each of a page Because a lot of similar content pages, or automatically generated content, users do not have much value, but we have such a huge volume of the index are proud that our goal is to index the world's data."

谷歌Web搜索基础设施小组软件工程师耶西。阿尔波特和尼森。哈扎伊称："当然，我们不会索引这1万亿幅页面中的每一幅页面，因为很多页面内容相近，或是自动生成内容，对于用户没有太大价值。但是，我们为拥有如此巨大的索引量而感到自豪，我们的目标就是要索引全世界的数据。"

It is the first important step in video analysis and will directly affects the effectiveness of indexing Shot boundary detection is one of our major research interests and we will tackle the following existing problems the ambiguity between gradual change and camera motion, the discontinuity during gradual change, false detection caused by illumination variation and flashlight, automatic threshold selection Firstly, we discuss shot boundary detection in non-compressed domain In chapter 2, we compare some of the commonly used detection methods which are based on frame difference and point out that single feature will not generate good results As a conclusion, we use fuzzy logic to combine multiple features Presently, most frame difference based shot boundary detection algorithms rely on threshold and hence the selection of such thresholds will greatly affect the performance of boundary detection We propose a membership function to define frame difference and calculate the membership with self adaptation according to the statistic distribution of frame differences to satisfy different type of video clips Experiments show that the proposed fuzzy shot boundary detection algorithm can be used with different video types and has a high detection precision and recall In chapter 3, we discuss model-based shot boundary detection algorithms regarding chromatic and spatial editing effects such as fade-in, fade-out, dissolve and wipe Various parameters are proposed to better describe the characteristics of each editing type.

镜头边界的检测是把视频自动地分割为一个个镜头，作为基本的索引单元，因此它是视频分析重要的第一步，直接影响到视频检索的成败。镜头边界的检测是本文研究的重点之一。目前镜头边界检测算法主要存在以下问题：渐变与镜头运动难以区别；渐变过程中的不连续与停顿、光照条件的变化及闪光灯等特殊情况会引起误检测；自动选择阈值比较困难等。本文首先针对非压缩域视频进行了镜头边界检测的研究。在第二章中我们采用了比较流行的基于帧间差的方法。在比较各种帧间差计算方法的基础上，指出使用单一的特征难以取得很好的检测效果，提出用模糊逻辑综合使用各种特征。目前大多数基于帧间差的镜头边界检测算法都采用阈值法进行镜头转换的判别。阈值选择的误差对检测性能有较大的影响，本文提出用隶属度函数定义帧间差较大、中等较大和较小等概念，并根据帧间差的统计分布自适应地确定隶属度，以适应不同类型的视频片断。实验结果表明这种基于糊逻辑的镜头边界检测算法可以适应不同的视频，并具有较高的检测精度和检出率。在第三章中采用基于模型的方法进行镜头渐变的检测，研究了淡入／淡出、慢转换和扫换的模型。

When front courtyard careful, the agent of Yahoo net expresses, when Yahoo net searchs engine to search a picture, be search the webpage that contains picture information automatically from Internet, the accord with of unified resource fixed position that extracts picture file from which, generate a skeletonize automatically to pursue, in collecting picture index database.

庭审时，雅虎网的代理人表示，雅虎网搜索引擎搜索图片时，是从互联网上自动搜索到含有图片信息的网页，并从中提取出图片文件的统一资源定位符，自动生成一个缩略图，收录到图片索引数据库中。

The ProductID column in the Products table is the primary key, and an index has also been created on the CategoryId column (to create an index in the designer, just right click on a column and select "Indexes/Keys" to bring up the Index manager dialog).

Products 表中的的 ProductID 字段是它的主键（也是一个自动标识的索引键值），而 CategoryId 字段同样是一个索引字段（要创建一个索引字段，只需要右击字段，选择&Indexes/Keys&就会弹出索引管理对话框）。

The question's semantic comprehension model combines many natural language processing techniques, including Segmentation and Part-Of-Speech Tagging, the confirmation of the question type, the extarction of keywords and extending, the confirmation of the knowledge unit, Through these works, the intention of the user is holded, which greatly helped the last work of this system. The FAQ-based question similarity match model is implemented by sematic sentence similarity computation, which is improved by our system, this model can answer frequently-asked question fastly and concisely.The document warehouse-base automatic answer fetching model fistly deal with the document warehouse beforehand and construct inversed index, then use high efficient information retrieval model to search in the base and return some relevant documents, lastly, we use answer extraction technique to get the answer from these relevant documents and present it to users.

问句理解分析模块采用分词和词性标注、关键词提取及扩展、问句类型类别确定等自然语言理解技术，实现对用户提问意图的准确理解；FAQ 库问句匹配模块主要采用本系统改进的句子相似度计算方法来实现用户问句的解答，该模块主要用于实现用户常问问题的快速、准确解答；学科文档库答案自动获取模块在对学科文档库建立倒排索引的基础上，采用高效的信息检索模型对索引库进行检索，返回与用户查询表达式相似度较高的文档作为候选文档，针对从文档中直接获取答案难度较大这一问题，本系统采用答案抽取技术来实现问题的最终回答。

Respecting the problems arising form the use of terms in specific disciplines, thesauri can be used to solve them; therefore, it deserves careful study to find automated method for thesauri generation.

在学术资讯的语言问题上，索引典可以减少学科术语使用上的阻碍，因此需要致力於索引典自动产生方法的研究。
