Abstract: Libraries, archives, and museums play a critical role in organizing, preserving, and providing access to the cultural and historical resources of society. Digital technologies are used increasingly for information production, distribution, and storage. The institutions that have traditionally assumed responsibility for preserving information face technical, organizational, resource, and legal challenges in taking on the preservation of digital holdings. Maintenance will be critical to digital libraries; especially those who promote broad access to diverse, informal materials. If ignored, maintenance issues within the digital library, especially those relating to its materials will threaten its usefulness and even its long-term viability. We perceive the maintenance problem to be both technical and institutional, and this paper considers the preservation and maintenance of the digital library. The paper examines collection maintenance from several vantage points, including software architecture and the type of collection. The paper ends with an examination of potential technical solutions.

Abstract: Today the concept of e-learning or online learning is getting emphasis in many organizations like academic, research, corporate or government. But method of implementation of elearning is still a question. Many organizations have developed separate IT based systems for e-learning which are independent and costly as well. While others have preferred to develop e-learning modules integrated to their other IT technology based systems like KM System (Knowledge Management), Content Management System (CMS), or digital library. Digital Library provides a very well framed and compatible base for e-learning module. This article deals with various aspects of e-learning, strategies for e-learning implementation, role of digital libraries in developing e-learning, and few cases where digital libraries are successfully used in e-learning.

Abstract: The present practice of Ayurveda emphasizes on traditional way. The globalisation, patent, intellectual property rights issues and biopiracy are becoming major challenges in the indigenous traditional medical system like Ayurveda. So there is going to be crises and challenges in the Ayurveda system. In order to promote as a global medicine and equip Ayurveda to meet the global healthcare needs of the 21st century, there is an urgent need to modernise the ancient system in pace with the development of science and technology. So considering all these facts, Ayurveda is needed to restructure in the global context to meet the rising demands of a cyber society with the application of information and communication technology.

Abstract: There is an enormous range of available information in the world. In electronic environment many libraries have created a presence on the Web, but have we really thought about why we want to be there? Should library Web sites be grounded in the past or look forward to the future, or both? This paper has tried to focus on various issues related to the object and importance of the library homepage, how to create, what is requirement etc for library homepage. The role of the library is to select, acquire, organize and make available an appropriate subset of this information. Proving electronic information to its users has become a common feature of many special libraries through their homepages. A case study of IUCAA library’s homepage is presented. It discusses how IUCAA Library has taken challenges of the new emerging technologies and increasing demands of its users by adopting electronic information sources and services and how it generates value added electronic information for its users. This paper also describes the important electronic sources in astronomy & astrophysics, which is used in IUCAA library. URI: http://hdl.handle.net/1944/1545 Files in this item: 1

Abstract: Libraries are using Information and Communication Technologies (ICT) for their operations and services by making huge investments and spending vast amounts of staff time for the selection, acquisition, retrieval, and dissemination of digital information. But the proliferation of computers, widespread acceptance of computer networks, explosive growth of Internet, increased reliance on electronic databases and the move from dedicated mainframe environments to client-server environments make libraries vulnerable to security threats. The moment user connects the computer to a Network or Internet, is the moment that the security of data has been compromised. Even the most secure systems, shepherded by the most intelligent and able system administrators, and employing the most up-to-date, tested software available are at risk every day. It is very essential to take all measures to protect the ICT infrastructure from security threats. However, libraries are lagging behind in realizing the need to protect their ICT resources and services from misuse, damage, theft, sabotage, mistake, etc. This paper deals with the issues related to the security of libraries in the present digital networked environment and makes recommendations for protecting ICT resources and services. The paper discusses security risks, strategies for security, security policy, personnel security, physical security, software security, network security, Internet security, access control, protection against computer viruses, protection of public terminals and backup information. This paper also discusses the need for professional assignments for library security and the importance of security training for library professionals.

Abstract: Streaming audio became available on the Web in 1995, but with the development of the Synchronized Multimedia Integration Language (SMIL), the technology has reached a new level of maturity. SMIL is based on the XML standard, and allows audio, video, images, and text to be integrated. The implications for Web based pedagogy are tremendous. We now have the opportunity to do training on the desktop in a feature-rich open environment. We will give a basic background in streaming media technology, discuss the standards, the current state of the art, our experience with RealNetworks, how to take advantage of it in an intranet environment, and touch on future developments, including the integration of testing engines.

Abstract: In a search for more natural way of learning, streaming media is one of the ways. One old Chinese statement says: “a picture is worth a thousand words if used correctly“. Today we can ask ourselves how many words worth a video sequence? The use of online courses continues to grow worldwide, yet it is still not clear whether such online learning environments enhance the learning outcome of students or even meet the level of success of traditional classrooms. Many online courses represent no more than electronic versions of traditional classes without, of course, face-to-face interaction between instructor and students. These electronic courses often contain Web materials that lack any significant level of creativity or interactivity . Cognitive research suggests that the addition of multimedia can actually improve the learning process if certain methods are employed. By using auditory and visual methods of presenting information, students can process that information more quickly, often fostering an enhanced learning process.

Abstract: This study attempted to investigate students’ perceptions toward the use of the digital library for higher learning. Attention was given to three variables namely sex, year of study, level of course. A Likert – type instrument consisting of 10 items was designed to collect information about students perceptions. The respondents of this study were 72 students enrolled in various Post-graduate courses at Bishop Heber College, Tiruchirappalli. Collected data were analysed using ANOVA (Analysis of Variance). The overall results suggest that students had positive perceptions toward the use of digital library. Sex, year and level of course were found to be significant factors. Females, first year students and social science students had significantly positive perceptions. Implications for practices are discussed and recommendations are made for future research.

Abstract: Libraries have been undergoing tremendous developments in this era, adapting to the advent of information technology in the day to day working. Electronic, Digital Libraries have arrived. OPAC, CDROM databases, Electronic journals and Internet access exist in most Libraries. Libraries are no longer storehouses but are becoming gateways of relevant information. Some progress has been made towards increasing the relevancy of the data with the induction of various search engines and subject directories. Despite these activities, information sources remain scattered, hared to find and difficult to access. With the Internet, WWW and Information explosion, identification and extraction of information resources is an essential function of all libraries and information centers. The Electronic information sources are rapidly growing and with a wide variety in form and content it takes a lot of time to get the required information. Using technology the institutions, associations and individuals build a kind if network resource discovery service, called “Subject Gateways” on the web, which is de-facto network use environment. These subject gateways evolved during the last five years among early digital library projects within the library communities of the various countries. Subject gateways allow libraries and related organizations to explore the usefulness of their subject expertise in the organization of knowledge in the word of networkbased, Digital information. This paper gives an overview of the subject gateways, its definitions, feature and lastly some useful subject gateways and their services. URI: http://hdl.handle.net/1944/1551 Files in this item: 1

Abstract: Managing content in a reusable and effective manner is becoming increasingly important in knowledge centric organizations as the amount of content generated, both text based and rich media, is growing exponentially. Creating content is expensive and unless it is staged, deployed and reused effectively, these costs cannot be justified. An important aspect of content management technologies is that they are far from being mature and they are getting better with time and this will continue to stay this way for some more time. In this paper we discuss important features of next generation content management systems and key technology enablers that make it possible to achieve next generation functionality. We describe two important technology enablers that are implemented with state of the art research besides identifying evolving and futuristic research areas that will help push the content and information systems to the next level. We describe a technology framework for managing a unified taxonomy and ontology network and a common messaging platform. URI: http://hdl.handle.net/1944/1513 Files in this item: 1

Abstract: Associationship is an important component of data mining. In real world, the knowledge used for mining rule is almost time varying. The items have the dynamic characteristic in terms of transaction, which have seasonal selling rate and it holds time-based associationship with another item. In database, some items which are infrequent in whole dataset may be frequent in a particular time period. If these items are ignored then associationship result will no longer be accurate. To restrict the time based associationship, calendar based pattern can be used [5]. Calendar units such as months and days, clock units, such as hours and seconds & specialized units , such as business days and academic years, play a major role in a wide range of information system applications.[11] Our focus is to find effective time sensitive algorithm for mining associationship by extending frequent pattern tree approach [3]. This algorithm reduces the time complexity of existing technique[5]. It also uses the advantages of divide & conquer method to decompose the mining task into a smaller tasks for database.

Abstract: Web based resources have become increasingly important to the Academic community where the thrust is on on-going Research, Time bound projects and Consultancy. With information being added at a tremendous rate on the Net it becomes difficult to find the required information easily. The expectations from the users are its services. From the library and the librarian’s point of view the services should reflect the users quest for information. Services are the strength of any Library as they are no longer mere store houses. Reference service is one service that still retains its content, glory and importance. Reference service concerns with the internal and external resources through the Internet and other networks. These services are provided not only personally but also through electronic means. Most users go for a Google search still thinking how could the search strategy be better. Most times the answers lie in their Libraries without them knowing. A module E-Ref Desk on the lines of Ask a Librarian is designed to answer such queries.

Abstract: An error in classification can occur due to an error of omission, statistically known as a false negative or an error of commission, statistically known as a false positive. In order to build a perfect classifier, the false negatives and false positives have to be zero. With this in mind, we propose a two-tier model for the classifier. The first tier will reduce false negatives to zero and pass the results to the second tier. The second tier will reduce false positives to zero. We demonstrate the working of this model for the task of classifying sentences in Hindi as passive formations. The first tier will consist of a simple pattern matching system for filtering out sentences with likely passive formations without committing errors of omission. This will reduce the size of the corpus considerably. The second tier will work on the reduced corpus and make a complete grammatical analysis of these filtered sentences in order to reduce the false positives to a zero. The Anusaraka System [Bharati 1995] is a very good example of such a system. This paper concentrates on building the first tier. A hill climbing algorithm is proposed, where the start state is a list of patterns commonly found in passive formations. Each step up the hill will update the list of patterns such that the next state will bring down the number of false negatives, thereby reducing errors of omission. The hill climbing algorithm terminates when the false negatives are zero. URI: http://hdl.handle.net/1944/504 Files in this item: 1
