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.

Problems of synonyms and homonyms are also covered in this article and in the end the legal information services in modern era are discussed which include online and offline databases.
Temporal Association Rule Using Without Candidate Generation
(INFLIBNET Centre, 2005-02-02) Verma, Keshri; Vyas, O P
Associationship is an important component of data mining. In real world, the knowledge used for mining rule is almost time varying. The items have the dynamic characteristic in terms of transaction, which have seasonal selling rate and it holds time-based associationship with another item. In database, some items which are infrequent in whole dataset may be frequent in a particular time period. If these items are ignored then associationship result will no longer be accurate. To restrict the time based associationship, calendar based pattern can be used [5]. Calendar units such as months and days, clock units, such as hours and seconds & specialized units , such as business days and academic years, play a major role in a wide range of information system applications.[11] Our focus is to find effective time sensitive algorithm for mining associationship by extending frequent pattern tree approach [3]. This algorithm reduces the time complexity of existing technique[5]. It also uses the advantages of divide & conquer method to decompose the mining task into a smaller tasks for database.
Role of the Library Homepage as a New Platform for Library Services: A Case Study
(INFLIBNET Centre, 2005-02-02) Sahu, Hemant Kumar
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.

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
Subject Gateways: An Overview
(INFLIBNET Centre, 2005-02-02) Yadav, R T
Libraries have been undergoing tremendous developments in this era, adapting to the advent of information technology in the day to day working. Electronic, Digital Libraries have arrived. OPAC, CDROM databases, Electronic journals and Internet access exist in most Libraries. Libraries are no longer storehouses but are becoming gateways of relevant information. Some progress has been made towards increasing the relevancy of the data with the induction of various search engines and subject directories. Despite these activities, information sources remain scattered, hared to find and difficult to access. With the Internet, WWW and Information explosion, identification and extraction of information resources is an essential function of all libraries and information centers. The Electronic information sources are rapidly growing and with a wide variety in form and content it takes a lot of time to get the required information. Using technology the institutions, associations and individuals build a kind if network resource discovery service, called “Subject Gateways” on the web, which is de-facto network use environment. These subject gateways evolved during the last five years among early digital library projects within the library communities of the various countries. Subject gateways allow libraries and related organizations to explore the usefulness of their subject expertise in the organization of knowledge in the word of networkbased, Digital information. This paper gives an overview of the subject gateways, its definitions, feature and lastly some useful subject gateways and their services.

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.
