Abstract: The explosion of information on the Internet and information technology in general has created challenges for libraries to focus on developing more effective ways to meet the information needs of users. One practical approach is through customized portals performing simultaneous database searching. This paper presents a new library portal service used at the Indian Statistical Institute Library at Bangalore (ISIB). The key feature of a library portal is to allow searching across multiple databases without having repeat search. This feature is generally referred to as meta-search, parallel search, broadcast search or federated search. Discussion also includes strategies of local customization and the impact on library management in an electronic environment. URI: http://hdl.handle.net/1944/1558 Files in this item: 1

Abstract: Correlated The discovery of association rules is an important problem in data mining. It is a two-step process consisting of finding the frequent itemsets and generating association rules from them. Most of the research attention is focused on efficient methods of finding frequent itemsets because it is computationally the most expensive step. This paper presents a new data structure and a more efficient algorithm for mining frequent itemsets from typical data sets. The improvement is achieved by scanning the database just once and by reducing item traversals within transactions. The performance comparisons of the algorithm against the fastest Apriori implementation and the recently developed H-Mine algorithm are given here. These results show that the algorithm outperforms both Apriori and H-mine on several widely used test data sets. URI: http://hdl.handle.net/1944/1536 Files in this item: 1

Abstract: Correlated pattern mining has become increasingly important recently as an alternative or an augmentation of association rule mining. Though correlated pattern mining discloses the correlation relationships among data objects and reduces significantly the number of patterns produced by the association mining, it still generates quite a large number of patterns. This paper proposes closed correlated pattern mining to reduce the number of the correlated patterns produced without information loss. A new notion of the confidenceclosed correlated patterns is proposed first, and then an efficient algorithm is present, called CCMine, for mining those patterns. Confidence closed pattern mining reduces the number of patterns by at least an order of magnitude. It also shows that CCMine outperforms a simple method making use of the traditional closed pattern miner. Confidence-closed pattern mining is a valuable approach to condensing correlated patterns.

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: 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: 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. URI: http://hdl.handle.net/1944/1544 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: 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.
