Abstract: In order to bridge the digital divide between the sightless and sighted and to encourage literacy in them, we have designed an architecture for transcribing Braille from optically recognized Indian language. The system will help to convert masses of information in different Indian languages into a tactile reading form. The system mainly consists of OCR modules designed in an efficient manner to promote portability and scalability. In first section, we have introduced the importance and necessity of the work with successive sections clarifying briefly the properties of Braille and Indian scripts. We have also described the OCR work done with respect to Indian languages and the related work to our system. Finally, the System architecture is explained clearly followed by some conclusion and future work. The paper also identifies the needs to be fulfilled to percolate the benefit of the technology developed to the masses. URI: http://hdl.handle.net/1944/494 Files in this item: 1

Abstract: Now a day, developing a single OCR system for recognizing multi-lingual documents becomes essential to enhance the ability and performance of the existing document analysis system. Hence in this paper, we present a new technique based on contour detection and distance measure for recognizing multi-lingual characters comprising south Indian languages (Kannada, Tamil, Telugu, Malayalam, English Upper case, English Lower case, English Numerals and Persian Alphanumeric). Proposed method finds boundary for a character using contour detection and the result of contour detection is given to feature extraction scheme to obtain distinct and invariant features for identifying different characters of different languages. The method extracts invariant features by computing distance between the centroid and the pixels of contour of character image. We compare the experimental results of proposed method with result of existing methods to evaluate the performance of the method. Based on experimental results it is realized that the proposed method gives 100% accuracy with minimum expense and time. In addition, the method is invariant to Rotation, Scaling and Translation transformations (RST). URI: http://hdl.handle.net/1944/502 Files in this item: 1

Abstract: There are some situations where it is not possible to capture or scan a large document with given imaging media such as scanner or Xerox machine as a single image in a single exposure because of their inherent limitations. This results in capturing or scanning a large document image into number of split components of a document. Hence, there is a need to mosaic the several split components into a single large document image. In this work, we present a novel and simple approach for mosaicing the two split document images using wavelet decomposition to generate single and large document image. The proposed method uses the wavelet decomposition to speed up the mosaicing process by means of Multi Resolution Analysis (MRA). The pixel based and Column –Block matching procedures are used here to identify the overlapping region in the split images. The overlapping region is a common region which helps in obtaining mosaiced image from its split images. The proposed methods work based on assumption that the overlapping region is present at the right end of split image1 and at the left end of split image2 URI: http://hdl.handle.net/1944/1553 Files in this item: 1

Abstract: In this paper, we first present a memoized parsing method for reducing the efforts of computation in parsing the strings/ sentences of a formal’ natural language. We then discuss the statistical parsing that extracts the maximum/ most likelihood parse amongst the several parses of a string/ sentence in formal and natural domain as the most appropriate representative in disambiguation process. We integrate the statistical and memoized parsing together to achieve an efficient parsing technique. This integrated approach allows us to obtain the memoized-most-likelihood parse. Memoized-most-likelihood parse has an additional performance strength in the sense that it is highly useful further in parsing semantics. URI: http://hdl.handle.net/1944/501 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: Handwriting has continued to persist as a means of communication and recording information in day-to-day life even with the introduction of new technologies. Handwriting is a skill that is personal to individuals. Recognition of characters is an important area in machine learning. Widespread acceptance of digital computers seemingly challenges the future of handwriting. However, in numerous situations, a pen together with paper or a small notepad is much more convenient than a keyboard. Handwriting data is converted to digital form either by scanning the writing on paper or by writing with a special pen on an electronic surface such as a digitizer combined with a liquid crystal display. The two approaches are distinguished as offline and online handwriting respectively. It is necessary to perform several document analysis operations prior to recognizing text in scanned documents. This paper presents detailed analysis of various preprocessing operations performed prior to recognition of Tamil handwritten characters and the results are shown.

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.
