Abstract: 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.

Abstract: This paper describes a method for synthesizing images that match the texture appearance of a given digitized sample. This synthesis is completely automatic and requires only the “target” texture as input. It allows generation of as much texture as desired so that any object can be covered. It can be used to produce solid textures for creating textured 3-d objects without the distortions inherent in texture mapping. It can also be used to synthesize texture mixtures, images that look a bit like each of several digitized samples. The approach is based on a model of human texture perception, and has potential to be a practically useful tool for graphics applications. URI: http://hdl.handle.net/1944/497 Files in this item: 1

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: 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: The goal of this work is to develop an Open Agent Architecture for Multilingual information retrieval from Relational Database. The query for information retrieval can be given in plain Hindi or Malayalam; two prominent regional languages of India. The system supports distributed processing of user requests through collaborating agents. Natural language processing techniques are used for meaning extraction from the plain query and information is given back to the user in his/ her native language. The system architecture is designed in a structured way so that it can be adapted to other regional languages of India. URI: http://hdl.handle.net/1944/493 Files in this item: 1

Abstract: This article looks into the unique nature of challenges and opportunities facing the Free and Opensource (F/OSS) based software localizers’ community when it comes to enabling support for Unicode-based Indic Scripts in the domain of Library and Information Science (LIS). It describes the early background of Indian language support in LIS domain in terms of technology used, and moves into the present-day scenario of Unicode and Open standard based method of universal archival and access to information repositories that modern libraries represent with their multi-media capabilities. Unicode addresses many of the problems that had plagued earlier systems which had little or no capabilities in terms of universal accessibility, it also brings its own set of problems that demand solutions – e.g. the issue of collation sequences which assume significance when looked at from the perspective of indexed search capabilities in library software. While Opensource provides an open, pro-active, collaborative platform for rapid development, it still has to answer for issues like availability of extensive Opentype fonts, collation sequences, less-than desired quality of rendering by Indic script layout engines, as well as varying levels of maturity of software components that make up the technology stack on which Indic Support enabled Library Information Systems can and are being developed. The authors will try to seek answers to these practical questions by looking into their localization experiences with Koha – the world’s first Opensource library software into Bengali (this work is being followed by Hindi localization). Inputs will also include the experiences of the team from ISI, Kolkata which is working on localizing Greenstone Digital Library (GSDL) into Bengali. The article will draw upon the experiences of F/OSS Indic Localizers’ community to see whether cross-pollination of ideas can lead us towards the goal of bridging the Digital Divide.

Prakashe, Veena A (INFLIBNET Centre, February 2, 2005)[more][less]
Abstract: In this paper, the author attempts to enlist some of the basic bottlenecks that pose challenges while designing the automation of any natural language understanding system. In the beginning, some background material on the study of language and an overview of linguistics is presented for the benefit of the reader who might be new to the fields of artificial intelligence and cognitive science. Natural language systems are also discussed briefly so as to give a better insight into the processing of natural languages by computer systems. Then the three major threats or challenges of natural language processing, viz. knowledge acquisition from natural language; interaction with multiple underlying systems; and partial understanding of multi-sentence and fragments of language are discussed.

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

Nair, Shivashankar B (INFLIBNET Centre, February 2, 2005)[more][less]
Abstract: While English has predominantly maintained its lead both as the lingua franca of the Internet and also for basic man-machine interactions, the need of the day is a system that can cater to the native by facilitating such communication in the language he is most comfortable. This calls for the realization of Multilingual Systems that can present the same information in a variety of languages. The term Multilingual Computing in the present context refers to systems that are capable of running programs that accept, process and present data in more than one natural language. The concerned language for interacting with the computer may be selected at the time of invocation or use of the program. Such multilingual systems do not fully overcome the man machine barrier. The user still has to comprehend and react to the cryptic messages presented in the language of his choice. The problem can be overcome only by the use of natural language processing systems that can translate user commands and queries in his native language to machine level commands, facilitate execution and present the results in a manner that is very akin to the responses of a human being. This paper discusses the basic issues in the formulation of such multilingual systems. URI: http://hdl.handle.net/1944/492 Files in this item: 1

Abstract: 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.

Abstract: The development of natural language processing systems has resulted in their being increasingly used in support of other computer programs. This trend is particularly noticeable with regard to information management applications. Natural language processing provides a potential means of gaining access to the information inherent in the large amount of text and available through the Internet. In the following survey, we look in further details at the recent trends in research in natural language processing and conclude with a discussion of some applications of this research to the solution of information management problems.

Varma, Vasudeva (INFLIBNET Centre, February 2, 2005)[more][less]
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

Singh, Prachi (INFLIBNET Centre, February 2, 2005)[more][less]
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 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. URI: 81-902079-0-3 Files in this item: 1
