Multilingual Computing in Malayalam : Embedding the Original Script of Malayalam in Linux and Development of KDE Applications
(INFLIBNET Centre, 2005-01-02) J S, Rajeev; R, Chitrajakuma; K H, Hussain; N, Gangadharan
Indic Language Computing can be fully realized only through embedding vernacular scripts in operating systems. With the advent of OTF (Open Type Font) embedding local scripts in OS compliant with Unicode has become a reality taking computing beyond word processing. Microsoft has already come to this field strongly by embedding Devanagari in MS Windows. Compared to the closedness of Microsoft OS, free and open environment of Linux is ideal for the early accomplishment of multilingual computing. This paper describes initiatives of Rachana team in embedding Malayalam script in GNU/Linux operating system. Modules are added for KDE with its rendering engine QT so that the original exhaustive character set of Malayalam developed by Rachana is embedded fully in compliance with Unicode. For the first time, prospects are open to create DBMS and information systems using Malayalam script. Computing in Malayalam language is being initiated in the true sense only now. The procedures set up by Rachana-GNU/Linux is highly beneficial to the goals of INFLIBNET in fulfilling a total integrated bibliographic control of Indian literature in their native scripts.

A New Contour Based Invariant Feature Extraction Approach for the Recognition of Multi-lingual Documents
(INFLIBNET Centre, 2005-02-02) Manjunath, Aradhya V N; Hemantha, Kumar G; P, Shivakumara; S, Noushath
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).
Library Consortia Model for Country Wide Access of Electronic Journals and Databases
(INFLIBNET Centre, 2005-02-02) Francis, A T
The present approach towards partnership, networking, consortia and resource sharing adopted by Indian libraries need radical changes to evolve responsive partnerships in order to achieve best performance in service. The current practices of journal acquisition in most of the libraries in the colleges and universities in India are print based, in which each library is an island with regard to access of information. Moreover, there is wide disparity in the availability and use of information among different universities and colleges. But, consortia based acquisition and electronic desktop delivery of information can eliminate this gulf and increase the access and use considerably. Thus the difficulty now faced by the students, teachers and scientists in getting academic and research information will be eliminated on achieving full bibliographical control on the information documents available world over. This paper depicts the benefits of library consortia, analyses the present trend in the formation of consortia in India and suggests a new model of library consortia in which all academic institutions and government research organizations could participate. The formation of such a unique consortium under the direction and full support by the Government of India is stressed. The role that can be played by the INFLIBNET Centre of the University Grants Commission in the formation and management of such a consortium is also depicted. The areas of re-defining and re-engineering the operations of the university libraries necessitated by the consortia based electronic information and document delivery services are also discussed.

(INFLIBNET Centre, 2005-02-02) Devi, T Rama
Today on line education using computer-mediated communication to connect the learners and the instructors via the Internet (asynchronous learning networks) is more effective. Online queries are more in use than the traditional class tests. Tutorials conucted in traditional ways are all replaced by audio-visual conferences, e-mail, chat, listservers, news groups, simulations and guest chat on the Internet. Thus new learning modes and media is being initiated for enhancement of quality. The present paper discusses about the concept of digital library and building up of digital resources collection for effective E-Learning programmes. The importance of digitized grey literature collection to enhance the quality of e-learning programmes is highlighted. The digital exposition is a remedial answer by the little screen but extensive knowledge becomes positive and possible through a resourceful digital database.
Technology Enablers for Building Content Management Systems
(INFLIBNET Centre, 2005-02-02) Varma, Vasudeva
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.

(INFLIBNET Centre, 2005-02-02) Vikas, Om
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.
Natural Language Requirements to Executable Models of Software Components
(INFLIBNET Centre, 2005-02-02) Rathod, V R; Shah, S M; Modi, Nileshkumar K.
The UniFrame approach to component-based software development assumes that concrete components are developed from a meta-model, called the Unified Meta- component Model, according to standardized business domain models. Implicit in this development is that there is a Platform Independent Model (PIM) which is transformed into a Platform Specific Model (PSM) under the principles of Model-Driven Architecture. This paper advocates natural language as the starting point for developing the business domain models and the meta-model and shows how this natural language may be mapped through the PIM to PSM using a formal system of rules expressed in Two-Level Grammar. This allows software requirements to be progressed from business logic to implementation of components and provides sufficient automation that components may be modified at the model level, or even the natural language requirements level, as opposed to the code level.
Preprocessing Algorithms for the Recognition of Tamil Handwritten Characters
(INFLIBNET Centre, 2005-02-02) Shanthi, N; Duraiswamy, K
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.
XFML, Standard for Distributed Information Architecture
(INFLIBNET Centre, 2005-02-02) Suman, Aparajita
The unplanned dumping of information on WWW is the primary reason for the chaotic web of today. The way out of this WEB (in literal sense) seems to be only through planned organization of the burgeoning sources of information using faceted techniques. The role of XFML i.e. eXchangeable faceted metadata language gets defined in this context. The metadata language allows one to relate the topics of concern and to provide a meaningful way of accessing information. This paper tries to explore its nuances and suitability for defining distributed information architecture.
A Document Reconstruction System for Transferring Bengali Paper Documents into Rich Text Format
(INFLIBNET Centre, 2005-02-02) Chaudhuri, Anirban Ray; Singh, Debnath; Nasipuri, Mita; Basu, Dipak Kumar
The transformation of a scanned paper document into an editable form suitable for further processing such as desktop publishing or archiving in a digital library is a complex process. It requires solutions to several problems – document analysis by acquiring knowledge of document layout by a Page Layout Analyzer (PLA), followed by document recognition, which mainly comprises text recognition by Optical Character Recognition (OCR). Besides these two, another important problem is document reconstruction by transforming content into an electronically editable format by keeping the original layout intact. Core OCR modules exist on different Indian scripts, but no such document reconstruction system is available for Indian scripts. The document reconstruction system reported in this paper is the first of its kind on Indian scripts and it addresses document reconstruction for Bengali document images. The system makes use of the knowledge of both document layout extracted by a PLA in a graphical user interface (GUI) and the results of text recognition steps performed by OCR for transformation of paper documents into Rich Text Format.
Mutual Authentication Protocol For Safer Communication
(INFLIBNET Centre, 2005-02-02) Shantharajah, S P; Duraiswamy, K
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.
