Content management for digital delivery of agricultural information: redefining need of libraries in the context of digitization of theses and research reports
Get PDFAbstract. Universities and research institutes in the field of agriculture
in India have felt the need for the development of digital databases of
highly valuable documents such as theses, dissertations, research
reports, package of practices, etc. and taken up projects to fulfill it.
Agricultural universities and institutes of the Indian Council of
Agricultural Research (ICAR) have made attempts to develop digital
libraries by converting these documents. Kerala Agricultural University
(KAU) has developed a database of theses and dissertations. The Indian
Institute of Spices Research (IISR) also has done some digitization
work. The University has made an academic regulation insisting the
researchers to submit theses in digital format along with print copy.
The researhers have accepted the new system for theses submission and
also for information retrieval. Users prefer digital medium because of
several additional benefits. The retrieval techniques provided in the
database seemed to be an important criterion for accepting and using the
database. But, these activities have witnessed with some drawbacks
also. A follow up study was also conducted in KAU and IISR. This
paper tries to evaluate the digitization programme and highlights major
merits and demerits and forward suggestions for digital delivery of
agricultural research information. Findings of the study have also been
provided
Long term digital preservation
Get PDFThe field of digital preservation is being defined by a set
of standards developed top-down, starting with an abstract reference
model (OAIS) and gradually adding more specific detail. Systems
claiming conformance to these standards are entering production use.
Work is underway to certify that systems conform to requirements
derived from OAIS.
The fundamental goal of these systems is to ensure that the
information they contain remains accessible for the long term. We
develop a parallel set of requirements based on observations of how
existing systems handle this task, and on an analysis of the threats to
achieving that goal. On this basis we suggest disclosures that systems
should provide as to how they satisfy their goals
Principles for designing a digital library
Get PDFThis article covers some basic principles underlying the design,
implementation and maintenance of any digital library. These principles apply not
only to conversion projects in which analog objects are converted to digital form,
but to digital libraries in which the objects have always been in digital form
("born digitally") and to "mixed" digital libraries in which the objects may be of
both types. The key challenges in front of designing any Digital Library are
building the Resources, Interoperability, Intellectual Property and Effective
Access. These principles acts as a base while building a Digital library
Conceptual challenges for the evaluation of digital repositories with multiple access options
Get PDFThe evaluation of digital repositories with multiple access
options poses various questions concerning the choice of an appropriate
methodology and an adequate evaluation setting. Especially when
semantic concepts are represented by visual components a multimethodology
approach needs to be taken. This paper discusses such an
approach for coping with the various challenges. This work is based on
a digital image repository that allows multiple access via semantic
concepts such as topic maps, classical full-text search and content-based
image retrieval. This system is the central part of a research project
known as Living Memory
Designing digital architecture with intelligent building for information access at the Tuberculosis Research Centre, Chennai
Get PDFThis paper focuses on how the digital architecture is
being effectively used in the Tuberculosis Research
Centre’s library for information access system making it
more users friendly. More recently multi-media
information retrieval systems have become vital with
increased international attraction/attention. This will
increase the end users and their platforms connected to
the internet/intranet. Further this will explore the
opportunities for research at the intersection of web and
user’s information. Moreover this will bring out how
simply the computational infrastructural tools are being
utilized in remote access to reach publicly available
information
Library services to blind users in digital environment: their fundamental right in the information age
Get PDFAbstract Published in Seminar Papers 51 st All India Conference: ILA, 2005:p183.Discusses the need of Digital Library for blind users, present condition of blind libraries in India, legal aspects of equal rights to information access by these users in the scenario of library and information, the role of LIS organizations and professionals, guidelines and basics of developing a digital library for visually impaired after understanding the appropriate approaches in respect of utilization of latest technologies
Digital libraries : reaching out to people with special reference to India
Get PDFThe vision of Digital Libraries is not new. This is a field in which
progress is being achieved by the incremental efforts of numerous people
over a long period of time. The vision is being realized at the global
perspective. Digital libraries can be an essential resource for human
learning and development. These libraries have the strong potential being
far more flexible than conventional ones. Major initiatives to start digitizing
the existing resources by various institutions and libraries as well as some
digital library projects in the context of rural development in India are
studied in this paper. We need a strong strategy at the national level for
availability and usefulness of digital libraries, this can help move the nation
toward realizing the enormously powerful vision of ‘anytime, anywhere
access to the best of human thought’
Semantic web domain knowledge representation using software engineering modeling technique
Get PDFThe semantic web offers a great deal of deviation from the
way in which the current search engines which are based on the
traditional information search theory work. Semantic search is carried
out by ontology based intelligent information retrieval. So a good
semantic search needs a good ontology. The ontology developers need
more familiar notations and tools for a uniform representation of
ontologies. UML being a standard modeling language in software
engineering, it is better supported in terms of expertise and the tools as
compared to the upcoming semantic web languages. This work
proposes a representation technique which is based on software
engineering standards namely UML for modeling domain knowledge
of the Semantic Web. The ontology for Company Domain has been
presented using this software engineering modeling technique. The
UML tool like Rational Rose tool can be used to provide support for
modeling complex ontologies of the given domain
Ontology-based Navigation of Bibliographic Metadata
Get PDFThis paper describes the work done within the Food and
Agriculture Organization of the United Nations (FAO) on providing an
ontology-based navigation for the Food, Nutrition and Agriculture
(FNA) Journal. The aim of the revised navigation was to provide more
efficient and effective browsing of the Food and Nutrition Publications
using a knowledge model to guide the user with concepts and
relationships relevant to a specific subject area. With this approach, data
from two different bibliographical databases was merged, unified and
presented to the user with improved services. A preliminary metadata
merge was needed to combine all the information into one system in
order to produce a metadata-ontology. Resource Description
Framework Schema (RDFS) was chosen to exploit semantic
relationships, e.g. the possibilities of browsing the data in different
ways (by keywords, categories, authors, etc.), and the creation of a
multilingual concept-based advanced search
Information Retrieval in Indian Languages: A Case Study of Plural Resolution in Telugu Language
Get PDFThe paper deals with developing stemming algorithms that could be applied to develop a search and retrieval system for digital documents in Telugu - a language belonging to the South-central branch of the Dravidian languages. A set of stemming algorithms is developed to index and search for documents in the Telugu language. The algorithms developed demonstrate successfully that stemming algorithms for Indian languages can be developed for increasing the search efficiency in Indian languages
