Organisation of Web pages Using Document Clustering Techniques: Some Algorithms
Get PDFWith the increase in information on the World Wide Web it has
become difficult to find the desired information on search
engines. Clustering Techniques are now being used to give a
meaningful search result on web. This paper gives an idea
about Web Page document clustering, different algorithms
including similarity measures and clustering engines
Design and Implementation of Networked Digital Libraries: Best Practices
Get PDFThis paper introduces the concept of Networked Digital Libraries
(NDLs). Discusses the important components of NDLs. Also presents
case studies of a few NDLs. Summarizes the best practices for design
and implementation effective NDLs
Creation of Digital Libraries in Indian Languages Using Unicode
Get PDFUnicode is 16-bit code for character representation in a computer.
Unicode is designed by Unicode consortium. It represents almost all
the world script including extinct many of extinct scripts like Bramhi
and Kharosthi. ISCII is another code developed for to represent the
Indian characters in computer but there are problems with character
representation using ISCII. It is found that Unicode can solve the
problem. This paper suggests measures for creation of Digital
library in Indic languages and the problem associated with Unicode
Metadata Crosswalks with MarcEdit using XSLT
Get PDFRetro-conversion tools are heavily used in libraries for data
exchange. The advent of Web has brought the concept of
Digital libraries and semantic web. This movement has
increased the use of metadata from different domains. In such
a situation libraries often feel to convert web based metadata
schema to their native metadata schema. XSL Transformation
is a wonderful tool for such kind of conversion which is used by
MarcEdit, a bibliographic data editor designed at Oregon
State University. This paper is a tutorial for using XSLT and
MarcEdit
Identification Schemes for Digital Resources
Get PDFThis paper discusses the various naming and addressing
systems used to identify and locate resources in the digital
environment. There are various schemes that have been
developed for this purpose, like, URL, URN, URC schemes
developed by the IETF (Internet Engineering Task Force),
PURL developed at OCLC. The publishing industry also has
developed the Digital Object Identifier (DOI), which is being
used for rights management of intellectual property. The
specifications and the working of URLs, URNs, PURLs,
Handles and DOIs are discussed in detail in this paper
Semantic Web and Resource Description
Get PDFKnowledge representation could be a powerful tool for search in
digital collections. Semantic Web is commonly used knowledge
representation technique in building Expert systems. It can be very
well utilized in information retrieval in digital collections as well as
Internet. Paper discusses the tools and techniques for knowledge
representation using Semantic Web as well as its impact on the
precision of search results in digital collections
Copyright and Digital Libraries
Get PDFThis paper discusses the copyright Act of India in the context of
digital libraries. The copyright Act prevents the unauthorized use of
authors’ original work in India. With the current technological
developments in Information Technology, information can be
accessed easily. Current copyright law does not discuss about the
digitization aspect – particularly its storage, use in the network
environment and fair use in the digital environment. However to a
great extent, the latest amendments of copyright act discuss about
the computer software, piracy etc. This paper discusses the IT act,
2000, Fair Use in electronic environment etc. It gives a brief idea to
the readers about the copyright issues and its implications in the
digital libraries
Digital Information Preservation
Get PDFDigital technologies present a preservation solution for the
documents in the libraries with increased access to digitized
documents over the electronic networks. Digital technology as well
as all other associated Internet and Web technologies is in a
continuous flux of change. The digital librarian is threatened by
”techno obsolescence” and transitory standards. In recent decades,
many major libraries and archives have established formal
preservation programs for traditional materials which include
regular allocation of resources for preservation, preventive
measures to arrest deterioration of materials, remedial measures to
restore the usability of selected materials, and the incorporation of
preservation needs and requirements into overall program planning.
This paper represents the challenges of digital preservation and the
strategies for solving the preservation problem
An Overview of the Semantic Web
Get PDFThe phenomenal growth of content on the Web has made it
difficult to locate, organize, and retrieve information. One way
to cope is to automate these tasks. But because of the
complexity of natural-language processing, we still do not have
machines that can understand and analyze the content on the
Web as humans do. The main idea behind the Semantic Web is
to develop technologies and applications that will make the
machines to understand information semantically and perform
the desired task. This paper discusses some of the technologies
like URI, XML, RDF and ontologies which are the core
technologies being used now to develop the Semantic Web
Mobile Access to the Digital Library
Get PDFThe paper discusses the access of Digital libraries through
other devices. It discusses the issues like size of the screen for
display, mental model, access to critical data, etc. which may
seriously affect performance in mobile environment
