| 1. | The author bring forward meta search engine model mysearch , it mainly comprises user interface agent , search agent and search database 作者提出了一个元搜索引擎模型mysearch ,它包括了用户界面代理,检索代理,查询数据库这三个部分。 |
| 2. | The answer system includes online question - and - answer and non - online question - and - answer web pages , which can also complete automatic answer by searching database 系统基本实现了研究目标。由于时间关系, 、两组内容未予探讨研究。 |
| 3. | In chinese 67 wang s , zhang k l . searching databases with keywords . journal of computer science technology , 2005 , 20 : 55 - 62 数据库和信息检索两种技术长期独立发展,都取得了卓著的成果, internet的发展促进了两种技术的融合,提出了新的研究课题。 |
| 4. | Second method only use longitude - latitude orientation average radius distribution feature , l1 distance function and indirect searching database . in third method , 3d model is equally divided into 16 parts in z axis orientation firstly 第二种检索技术提取经纬方向平均半径分布作为特征向量,相似度计算使用l _ 1距离,直接检索特征数据库。 |
| 5. | Her current research interests include scalable advanced database technology , data warehousing and business intelligent technology . she is also interested in grid data management and searching databases with keywords 高性能数据库新技术的研究与系统软件开发数据仓库和bi技术研究网格环境下的数据管管理新技术研究数据库检索新技术研究等。 |
| 6. | Usage would include tasks like recursively searching files for virus patterns , searching databases for keys or data , text and word processing and any other task that requires handling large amounts of data at very high speed 这种算法的用途包括采用递归方式搜索文件中的病毒字符串,在数据库中搜索关键字或数据,文本和单词的处理,还有其他要求非常高速地处理大量数据的场合。 |
| 7. | It provides users a unique interface , accept the query terms , run and return the results like meta - search engine do . in this paper we have developed a wan search database query system for practice use , and this project is supported by national funds 广域网数据库查询系统提供用户关于某一类数据库信息的统一的查询界面,它调用各个独立网站数据库系统对用户输入的查询条件进行实时并发查询,同时合并查询结果返回给用户。 |
| 8. | There are two features used in first method : area distribution of 3d model surface and latitude orientation average radius distribution . quadratic form distance function has been applied to calculate the similarity of two feature vectors and two passes are needed to search database in first method 第一种检索技术使用了两个特征:面积分布和纬度方向平均半径分布,在相似度计算使用了二次方程式距离计算公式,数据库检索采用了分步检索方法。 |
| 9. | Then there are also two features to be extracted : the average distance of all points of every part and distance histogram distribution of all points in every part . the similarity calculation is same as that of second method , while the searching database is same as first method in third method 第三种检索技术将3d模型按z轴方向等分成16块,然后提取两个特征:分块平均距离和分块距离直方图分布,相似度计算使用l _ 1 ,距离,数据库检索同样采用了分步检索。 |
| 10. | Abstract : the basic theory and function of cd retrieval and systemic constitution of multimedia searching databases cd co - developed by the author and tsinghua university is stated . the system consists of load , databases , html browser , editing and print . the system almost holds out multimedia format and has powerful retrieving function , it not only involves all methods of manual retrieval , but also carries out logic and mixed retrievals . the process in fact is one during which data are matched . the result shows : cd databases make retrieving popularized , simplified and have vast foreground in storage 文摘:介绍了作者与清华大学合作开发的多媒体全文检索数据库光盘的系统组成与光盘的检索功能及原理.系统由标引系统、资料建库系统、超文本浏览器、编辑出版系统组成.该系统几乎支持所有的多媒体格式,具有强大的检索功能,不仅囊括了手工检索的全部方法,还可进行模糊逻辑检索和任意混合检索.其检索过程实际是一个数据匹配的过程.实践证明,光盘数据库使检索大众化、简单化和普及化,在信息储存方面前景广阔 |
