1. 1 Challenges and Emerging Practices for Knowledge Organization in the E-Environment. Anil Kumar Mishra LIO, NCHRC, NIHFW New Delhi Email: anilmlis@gmail.com

2. There is huge volume of information available on the Internet 2 Yahoo alone claims to have indexed 20 billion documents. Search Engine Exalead indexed about 7 billion documents. There are one million videos on Youtube About 7 lack electronic books and niche titles are published every year. Web is growing at the @300 percent every year.

4. In the North America, the percentage of the Internet penetration in population is 77.4%,whereas users are 13.5% of population.

5. In the European region, percentage of its penetration in population is 58.4 percent, whereas users are 24.2% of population.

8. Enormous volume of information is available, whereas an individual information user has a limited time and capacity to make use of such information resources.

9. The challenge for individual user is to make choices of documents to use in a given time constraint.

11. This requires categorization and organization of worthwhile hypermedia according to some order or schema. 7 Hypermedia offers an exciting new method of linking and searching information. It promptly facilitates spatial search of collateral sources of information cited or linked with a document. Any further effort for hypermedia documents’ organization has to be pursued keeping in view and keeping intact this intrinsic feature of hypermedia. As the Internet is now increasingly concentrating on personal space, any hypermedia organization schema should also offer an information prescription to an end user’s information problem. It must meet the ultimate objective of customized and personalized dissemination of information.

12. Hypermedia and Different subject areas 8 In certain subject areas hypermedia documents can offer a way to create information chains for better understanding of past developments for facilitating future course of action. For instance. In the subject area of law, latest case decisions can be hyperlinked with previous judgments of other courts and relevant legislations. In the subject field of history, latest development and contemporary situations can be hyperlinked with the past happenings that may themselves be organized in the chronological order. In chemistry, documents reporting new compounds can be hyperlinked with the related past research to provide comprehensive information for better understanding of development of new compounds. Patent documents in a specific area may be linked to trace the course of inventions and study technology history.

13. Fluid information environment 9 The present fluid information environment offers, a fertile field for knowledge organization and information architecture research. Focus is desired to develop knowledge organization tools and practices that may facilitate instant packaging and repackaging of information content giving due credit to authorship and respect to copyright laws. Efforts are also desired for standardization of such tools and practices at the international level in the interest of information processing global information communication.

15. Go for application of artificial intelligence methods involving decomposition and coordination of information content for multi-tasking, complex multi-objective systems and supporting mission oriented work.

18. OCLC’s Net First database has been using an adapted version of DDC.

19. Canadian information by subject at the National Library of Canada, Net sites by numbers at the Tempe Public Library, Arizona also use DDC.

20. Social Science Information Gateways (SOSIG) and GERHARD- The German Academic Web Index used Universal Decimal Scheme (UDC) for organization of web documents.

21. Engineering Information, Inc’s subject scheme is used for organization of EELS documents.

23. Scotland culture Service (www.scotlandculture.org) have information resources that are indexed using Library of Congress Subject Headings (LCSH).

24. Artifact (www.artifact.ac.uk) employs the Art and Architecture Thesaurus (AAT).

27. Users themselves assign keywords to information resources and these system tags can also be looked at and searched by other users.

28. However, keywords assigned to information are sources are not from controlled vocabulary of any information retrieval system and depends on users, approach and perspective of looking at the content.

30. There is considerable scope for experts from both the fields to work together and co-design tools for hypermedia organization and searching.

31. However, most of ongoing work in this area is parallel rather than understanding techniques and work domains of each other and collectively work together to develop most appropriate and user friendly methods of hypermedia organization.
