Semantic Enhancement of Social Network Relationships: A Proposal
No full textSocial networks reveal the web of connections that exist among individuals.
The meaning of these relationships, however, remains largely unspecified. Generally, automated techniques fall short when it comes to identifying their nature. This paper discusses the use of crowdsourcing techniques to leverage expert knowledge for classifying social relationships derived from digital archival materials. In order to enhance the semantics of social relationships with contextual information (e.g., space and time), an application is proposed that relies on human annotation driven by dynamically-generated
questions. The system has the potential to provide scholars with a tool to support their analysis and enhance their understanding of the structure and dynamics of social groups and communities
Knowledge Management Initiatives, Applications and Best Practices at IBM and UNDP: An Analytical Case Study
No full textSupporting Multi-Target Semantic Hyperlinks
No full textThe current World Wide Web supports only simple hyperlinks with a single
destination and without any semantics for the link. In this paper we present a mechanism to extend the idea of a hyperlink to support multiple-target XLinks with added semantic roles for each target locator. We also demonstrate how such a link – called SuperLink – can be implemented in scripting languages such as XSLT and JavaScript so that it can be supported in any browser. Further, we illustrate an application of such SuperLinks in an e-commerce
scenario of mapping electronic gadgets to their compatible accessories where significant improvements in usability can be achieved through the mechanism. Moreover, our design includes a call-back mechanism so that developers can add their own JavaScript implementations to handle any semantic attributes in the link to create custom behaviors
Multi-Class Classification for Prediction of Retinal Diseases (Retinopathy and Occlusion) from Fundus Images
No full textMedical Imaging and Mining provide very useful information for the medical
practitioners. In the field of ophthalmology, fundus images capture the retina of the eye. A lot of diseases like different types of retinopathy, types of occlusion, Choroidal Neo-vascularisation, Glaucoma, Macular Degeneration etc., can be diagnosed from the analysis of the fundus retinal images. Retinopathy and Occlusion are the sight threatening diseases that demand early detection. In this paper, prediction of Retinopathy, Occlusion, other disease affected and normal cases is attempted through extraction of overall image features. The
automatic detection is done through color channel extraction, contrast enhancement, overall image feature (Statistical, GLCM, Histogram based features) extraction and classification. STARE, a publicly available repository of retinal fundus images is used for training the system. It is observed that Random Tree Classifier yielded the best performance achieving an
accuracy of 96.15% in detecting presence of disease, 76.92% in detecting Retinopathy, affected by other disease or normal and Random Committee classifier yielded the best performance yielding an accuracy of 84.62% in detecting Occlusion, affected by other disease or normal and 64.12% in detecting Retinopathy, Occlusion, affected by other disease or normal
Library and Information Science Trends and Research: Asia-Oceania
Full text linkAcknowledgements: The author wish to thank Prof. Amanda Spink for her invaluable advice and insightful comments to improve this chapter. Also, the author is grateful to Mr. Eric & Mrs. Helena Bauert-Keller for their support.This chapter outlines current developments in Indian libraries,
information services and cultural sector. We highlight recent trends
and developments as India increasingly takes centre stage in the area of
libraries and information literacy development. The chapter also
provides a critical analysis of library and information science education
in India and highlights the need for government strategies and policies
related to public libraries. Some 17 federal states and union territories in
the Republic of India have no public library legislation and therefore low
literacy rates. India needs public awareness campaigns, civic engage-
ment and community developments including the grass-roots empower-
ment of public libraries. Financial reforms, modernization and federal
funding strategies for public libraries are also required to energize
cultural organizations and national libraries. A recent major develop-
ment is the establishment of a National Commission on Libraries
following recommendations by the National Knowledge Commission.
However, Indian public libraries do not cater sufficiently for the growing
youth population or other strata’s of Indian society. The growing Indian
higher education sector also necessitates information policies for open
access, digital preservation and repositories development
Usefulness and Applications of Data Mining in Extracting Information from Different Perspectives
Full text linkhttp://nopr.niscair.res.in/bitstream/123456789/11552/1/ALIS%2058(1)%207-16.pdfThis paper discusses on the concept of data mining, emerged as a technique of discovering new meaning in data implicit in a large data warehouse, in order to facilitate better strategies and smart decisions. The standard tasks involved in data mining process are explained. However, such pattern-seeking techniques usually performed with a wide range of related areas (viz. statistics, neural networks, genetic algorithms, machine learning, pattern recognition, knowledge-based systems, etc.) are described. It draws attention to useful applications of data mining in varying degrees and illustrates the benefit of this powerful technology with several instances of providing solutions to challenging problems. It also focuses on bibliomining opportunities to be useful to information retrieval, semantic analysis of unstructured texts, web-usage mining and to make proactive as well as knowledge-driven decision across library services; thus help researchers in linking information for novel discovery and insight. The discussion illuminates the wrong things do happen with data mining applications and cautionary tales for avoiding serious consequences. Therefore suggests for using data mining in combination with other techniques of evaluation, exploiting large data warehouses by skilled specialists, and advises for ethical uses without privacy invasionIndian Statistical Institute, Kolkat
Use of web technology in providing information services by south Indian technological universities as displayed on library websites
Full text linkAbstract
Purpose - This paper aims to discuss the present status of using new generation web
technology, social media and Web 2.0 features among the technological university library
websites in south India. It assesses the library websites as a primary platform and one-stop
portal for information services and examines as to how much library websites are effective in
providing web-based information services.
Design/Methodology/Approach - The library websites of the technological universities in south
India were evaluated on the basis of a relative weight checklist. The criteria for the checklist was
drawn on the basis of availability of websites for library, resource discovery tools, access to
scholarly content and Web 2.0 tools. The various issues and challenges in adapting new web
technologies in academic environment are discussed.
Findings - Using the current web development technologies and deploying for mainstream web
information services is not widespread as web information services are yet to take off widely in
academic libraries. The majority of university libraries are found to be working in the
conventional library settings and the diffusion rate of web information services is relatively low.
Originality/value - As this is an assessment of the existing online information infrastructure
facilities of the engineering universities in south India, the awareness of web-based information
services, their viability, and service values can be enhanced. More emphasis is underlined to
improve upon the current learning, online educational facilities and benchmarking electronic
information services for sustainability is highlighted.

Review on matrimonial information systems and services - an Indian perspective
Full text linkin International Research Journal of Library, Information and Archival Studies, 1(4) November 2011, p.126-135.Marriage information has always been an integral part of the knowledge base in any civilized society. Usually some agencies and other de-institutionalized sources become operative in producing and transferring great variety of matrimonial information. In recent time, online matrimony portals accelerate the opportunities of providing newer matrimony services for sharing matrimonial information more comfortably and selectively, though often criticized in terms of adequacy and authenticity of such information. This paper aims to present a brief account on marriage information systems and services with reference to India, thus provide glimpses of popular matrimony sites emerged in last two decades. It evaluates the usefulness and web-metrics as well as popularity of broad-spectrum matrimony portals; those have become accessible to diverse Indian communities, and beyond the geographical boundaries. It emphasizes on proper coordination and standardization among the service portals toward developing a comprehensive information system for potential marriage-information seekers in national, regional, and local level. New policy initiatives and technological capabilities might provide more effective platform is suggested to reveal a new matrimony space in India.Indian Statistical Institute, Kolkat
