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: Data transmitted through a network may be protected from unauthorized receivers by applying techniques based on cryptography. Only people who possess the appropriate private key can decrypt the received data using a public algorithm implemented either in hardware or in software. Fast implementation of encryption-decryption algorithms is highly desirable. Data-content manipulation can be performed for various legal or illegal purposes (compression, noise removal or malicious data modification). The modified product is not authentic with respect to the original one. The technology of multimedia services grows rapidly, and distributed access to such ser-vices through computer networks is a matter of urgency. However, network access does not protect the copyright of digital products that can be reproduced and used illegally. An efficient way to solve this problem is to use watermarks. A watermark is a secret code described by a digital signal carrying information about the copyright property of the product. The watermark is embedded in the digital data such that it is perceptually not visible. The copyright holder is the only person who can show the existence of his own watermark and to prove the origin of the product Reproduction of digital products is easy and inexpensive. In a network environment, like the Web, retransmission of copies all throughout the world is easy. The problem of protecting the intellectual property of digital products has been treated in the last few years with the introduction of the notion of watermarks.

Abstract: Here we present about automatically generated ontologies for a semantic web search system using data mining techniques. This will improve the query process and will get better semantic results. Ranking algorithm[1] is used to search and analyze web documents in a more flexible and effective way. Hyperlink structure of web document is utilized to rank the results. We use association rule mining to find the maximal keyword patterns. Clustering is used to group retrieved documents into distinct sets. This will extract knowledge about query from the web, populate a knowledge base. The search engine that searches the web documents so far are syntactic oriented. Here we develop a searching system that semantically searches the documents. The semantics of the terms is achieved using the ontologies. Ontology serves as Meta data schemas, providing a controlled vocabulary of concepts, each with explicitly defined meaning. Ranking algorithm used here is the hyper textual ranking algorithm that scans both the contents of the documents and also the reciprocally linked documents. This technique has several advantages that include providing better semantic notion during the search. It also serves for multiple frame documents. There is a need for automatic generation of ontologies when using the semantic searching system. The paper here focuses on how the automatic generation of ontologies could be done for a semantic search system using data mining techniques.

Abstract: Our information and knowledge environment has been and continues to be changed by the development of the Internet and ubiquitous communication technologies. Information and knowledge are replacing capital and energy as the primary wealth-creating assets, just as the latter two replaced land and labor many years ago. In addition, technological developments in the 20th century have transformed the majority of wealth-creating work from physically-based to “knowledge-based.” Technology and knowledge are now the key factors in development of economy of the country. With increased mobility of information and the global work force, knowledge and expertise can be transported instantaneously around the world. We are now an information society in a knowledge economy where knowledge management is essential. The paper presents an overview of the role of digital libraries in the knowledge economy, its prospects and issues. URI: http://hdl.handle.net/1944/1534 Files in this item: 1

Abstract: Correlated pattern mining has become increasingly important recently as an alternative or an augmentation of association rule mining. Though correlated pattern mining discloses the correlation relationships among data objects and reduces significantly the number of patterns produced by the association mining, it still generates quite a large number of patterns. This paper proposes closed correlated pattern mining to reduce the number of the correlated patterns produced without information loss. A new notion of the confidenceclosed correlated patterns is proposed first, and then an efficient algorithm is present, called CCMine, for mining those patterns. Confidence closed pattern mining reduces the number of patterns by at least an order of magnitude. It also shows that CCMine outperforms a simple method making use of the traditional closed pattern miner. Confidence-closed pattern mining is a valuable approach to condensing correlated patterns.

Abstract: Correlated The discovery of association rules is an important problem in data mining. It is a two-step process consisting of finding the frequent itemsets and generating association rules from them. Most of the research attention is focused on efficient methods of finding frequent itemsets because it is computationally the most expensive step. This paper presents a new data structure and a more efficient algorithm for mining frequent itemsets from typical data sets. The improvement is achieved by scanning the database just once and by reducing item traversals within transactions. The performance comparisons of the algorithm against the fastest Apriori implementation and the recently developed H-Mine algorithm are given here. These results show that the algorithm outperforms both Apriori and H-mine on several widely used test data sets. URI: http://hdl.handle.net/1944/1536 Files in this item: 1

Abstract: The explosion of information on the Internet and information technology in general has created challenges for libraries to focus on developing more effective ways to meet the information needs of users. One practical approach is through customized portals performing simultaneous database searching. This paper presents a new library portal service used at the Indian Statistical Institute Library at Bangalore (ISIB). The key feature of a library portal is to allow searching across multiple databases without having repeat search. This feature is generally referred to as meta-search, parallel search, broadcast search or federated search. Discussion also includes strategies of local customization and the impact on library management in an electronic environment. URI: http://hdl.handle.net/1944/1558 Files in this item: 1

Abstract: In the present society, information is treated as one of the most valuable resources and its importance has increased manifold in the networked digital environment. No doubt, the developments in the field of IT have facilitated the sharing of information from one knowledge domain to another, but the difference in terminologies acts as communication barrier and impedes the free flow of information. Various terminological and lexical databases have been developed to help the professionals; however, the problem of data interchange/ exchange across different platforms still persists. This paper gives an overview of MARTIF and OLIF, the tools for platform independent terminology exchange/ interchange. URI: http://hdl.handle.net/1944/1539 Files in this item: 1

Abstract: With web search getting to be more and more popular, and predictions that they would be even more popular in the coming years, given the exorbitant growth of the web in recent years, search engines, in their quest to be branded the best, have regularly been providing additional features. The users of web search interfaces are typically diverse and have wide ranging interests. This is in contrast to other application interfaces which cater to a specialized group of people. In this study, we examine the influence the interface manifestation of such features has, in their usability and effectiveness. URI: http://hdl.handle.net/1944/1542 Files in this item: 1

Abstract: With a network communication requires cryptography authentication for secure transmission. This paper takes two challenge-response protocols by which entities may authenticate their identities to one another in a mutual communication way. Here the two entities, each holding a share of a decryption exponent, collaborate to compute a signature under the corresponding public key. These may be used during session initiation, and at any other time that entity authentication is necessary. The authentication of an entity depends on the verification of the claimant’s binding with its key pair and the verification of the claimant’s digital signature on the random number challenge. The network defined mutually authenticated protocols are for entity authentication based on public key cryptography, which uses digital signatures and random number challenges. Authentication based on public key cryptography has an advantage over many other authentication schemes because no secret information has to be shared by the entities involved in the exchange. This paper analyzes the protocols, which minimizes cost, very simple and suggests security for mutually signing the signature schemes and provides proofs of security for the safer communication. This paper specifies the way of mutual communication and the method of processing that conversation between entities. URI: http://hdl.handle.net/1944/1544 Files in this item: 1
