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.

Streaming Media to Enhance Teaching and Improve Learning
(INFLIBNET Centre, 2005-02-02) Pugazendi, R; Krishnan, A.; Jayabalan, E
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.
Performance of Memoized- Most- Likelihood Parsing in Disambiguation Process
(INFLIBNET Centre, 2005-02-02) Ingle, Maya; Chandwani, M
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.

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.
Building Up Digital Resources for Effective E-learning Programmes
(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.

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 Novel Approach for Document Image Mosaicing Using Wavelet Decomposition
(INFLIBNET Centre, 2005-02-02) Shivakumara, P; Kumar, G Hemantha; Guru, D S; Nagabhushan, P
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

(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.
