In this paper, we discuss about DRM technology and DRM solutions for digital audio/video service. First, we give an overview of DRM technology. Then we analyze two typical DRM solutions for digital audio/video service in detail. At the end, we discuss some key issues about their application briefly.
This paper describes the designation mechanism and function of MyLibrary@CSDL, and the application of MyLibrary@CSDL which help to build libraries portal quickly.
Digital library needs knowledge architecture to achieve its knowledge service really. Digital library’s knowledge architecture takes knowledge element as the element and take knowledge element linking as the pivot. It includes extracting knowledge elements from document information and then indexing them， building knowledge element warehouse and knowledge warehouse， and setting up the knowledge grid platform of digital library. In that， grid technology provides great strength to support digital library’s knowledge architecture.
This paper introduce the conception and purpose of RSS , and use the RSS to implement the syndication of the biblios resource of libraries in the WebPAC System.
The combination of the information resources in library and in network enviroment has become the research hotspot in the information field. In order to adapt the development of the network information and make use of the library resource fully,this thesis provides a method of coding the ASN.1 in the protocol Z39.50 with XER technology.
MVC is a software development pattern of program design. In this research we realized MVC making use of RequestDispatcher class of servlet API and some open-source components, and improved Navigation-System on Foreign-Language and Full-Text Electronic Journal of China Agriculture University.
A method for making the information repository of real-time reference services using FrontPage was introduced, including form of the repository, the advantages and skills to use the repository in practice.
Information Retrieval (IR) on the Web is the automatic retrieval of all relevant documents, the same as resource finding of intended Web documents, while the same time retrieves as few of the non-relevant as possible. Web IR has become very popular and favorite at present. It concentrates on the using traditional text IR methods in the Internet, as well as the properties of Web graph. This research focuses on how to effectively and broadly get relevant Web pages and contents, filter Web pages and assign proper labels for them. Accurate finding user-specific information in the Web is very difficult. And traditional Web search engines take a query as input and produce a set of (hopefully) relevant pages that match the query terms. While useful in many circumstances, search engines have the disadvantage that users have to formulate queries that specify their information need, which is prone to errors. Based on the discussion of Page Rank, HITS and similarity between Web texts, some new algorithms called RG-HITS (Resemblance Graph-HITS) for finding relevant documents on the Web are introduced.
The paper points out the difference between information filtering systems and other relevant systems. A framework is designed to classify information filtering systems under several standards and describe relevant filtering methods. The paper also describes some important concepts and technology in information filtering systems. And it discusses the elevation and shortcoming in information filtering systems. Finally, the paper describes the prospect of information filtering systems.
he method of content-based image retrieval is now a key technology to effectively query a mass of image materials. In this paper, a lot research work has been done around four points: how to abstract low-level feature of vision, how to index in high-dimensional, how to adjust similarity measure norm and use relevant feedback technique. An index method of abstract the color-feature and feature vectors is proposed, discuss the construction and editor program of system, and the operating of data model and testing of system. Experiment shows that the method could increase index accuracy and efficiency.
This article discussed the incredible-range of search engine features based on the search engine valuation, and give out the method and steps of incredible-ranges calculation.
The SDC (share data center) is the platform of collecting、processing、saving all kinds of share data, and supplying the information share services for the whole school. It carries out the data integration of each MIS, guarantees the consistency of the whole school share information, provides the support for the valid decision and for the new MIS development. After the analysis of saving and using the data at the present in universities, this paper gives the design of the SDC’s framework, and details the function components and the consideration of design.
With the digitally and networked development of library information resources, the workflow of library work and service mode are developed in networked and intelligent direction. Thereupon, the old method of reader flux statistic can’t fulfill the developing requirements of modern library anymore. Based on the modern computer techniques and e-Metric, an economical and practical network reader flux statistical analysis system is developed by us on present paper. The efficiency and accuracy of the system has been proved by the real application of it in our library.
Based on the practice of database construction concerning the Special Subject on the Document of Heluo Civilization in Luoyang Normal University, the article analyzes the conspicuous problems and technically difficulties in the construction of distinctive database and the solutions are also provided respectively.
How to effectively storage large number of XML data is an important problem of managing XML data. This paper analyzes four storage technologies for XML data storage based on the semi-structured characteristics, and presents the best storage strategies.
Based on the function request of human being’s information organ, the common development and share of E-government information resources can be realized by establishing information space based on network. The author thinks that during the research on establishing the common development and share of E-government information resources, we should consider well the relationship of power leading, benefit driving and information exchanges among governments and their working talent section. In general, the model of common development and share can be divided into three types: perpendicular type, level type, and compositive type. To optimize the model, we should follow the principles such as soft principle, institutional principle, tabular principle, and cooperative principle.
This paper introduces the general conditions of foreign online teaching platform and the function expand in user information literacy education, which indicate some messages on user education in our university library.
The article describes the design and realization of report management of science and technology projects in Anshan city based on ASP.NET, and details the logical architecture partition, the module dividing, the design and development of the system and etc. As a result, the system proves to be safer, quicker and easier to maintain.
This thesis introduces the development and virtue of RSS technology, and describes the application of RSS technology and RSS reader in library.
Introduce some problems when using PerfectSoft system 6.0, and solution methods.
