Enterprises and IKM
   Increased demand for improved information
    and knowledge management (IKM) solutions
       Integrate access to disparate information sources
        (internal/ external, print/ digital, local/ remote,
        free/ paid, etc.)
       Provide staff personalized information needed to
        make informed decisions




                                                   T.B. Rajashekar

   Impact factors:
       Growing competition – national, regional, global
            Competitive enterprise – sustain high level of
             competence, innovation and productivity among staff
             and business processes
       Growing volume of information (print, digital)
            Brought about by electronic publishing, Internet and the
             Web, intranets and digital libraries
       Growing preference for desktop access to local
        and Internet-based information

                                                           T.B. Rajashekar

Enterprises and IKM…
   Key challenges:
       How does an enterprise harness the rapidly
        growing volume of information to its competitive
        advantage?
       How do we capture, organize and provide
        effective access to information generated from
        internal processes?
       How do we identify, organize and provide
        effective access to relevant external information?

Enterprises and IKM…
   Key challenges…
       How can we integrate these two via a common
        information resource base and create a navigable
        online information environment allowing users to
        move between and around key resources?
       How can we relieve the user from „information
        overload‟ and facilitate personalized resource
        discovery?

Enterprises and IKM…
   Current EDIS strategies:
       Libraries/information centre: Access to external
        information
       Information systems/IT dept.: Access to internal
        information (MIS type)
       Trend: Compulsion to use intranets for integrating
        access to internal and external information
            Enterprise information portals

Enterprises and IKM…
   Limitations of current EDIS strategies:
       Arbitrary & (often) competing approaches used by
        different organizational units
       Lack of unified view of content and resource
        discovery across the enterprise
       Availability of competing solutions – commercial,
        open domain – complicates matters!
       Negative impact on productivity

Enterprises and IKM…
   Need for developing a new class of EDIS
       Achieve greater degree of integration and
        improved organization of disparate information
        resources and offer significantly improved services
       How? Development and management of EDIS
        should be facilitated by a design framework with
        an underlying, unified view of content and
        resource discovery across the enterprise & the
        Internet
       What are the elements of such a design
        framework?

EDIS: Key Goals
1. Develop and manage a dynamic, unified
   information resource base (content
   repository) that gathers and organizes
   relevant internal and global information
   resources, based on a taxonomy of
   information needs of the enterprise, and
   make these available for learning and
   informed decision making.

  Content Organization: Issues

         How the content is organized?
What intellectual organization we want to impose
                on digital sources?
  What cataloguing and markup standards are
                     relevant?
 How do we architect the website for providing
   single point access to all relevant sources?

              and authentication, etc.
        Standards:
             MARC, CCF (Libraries), Dublin Core (Websites)
        Dublin Core is a useful international standard for
         describing networked digital resources
             Adopted widely

Content Storage and Processing:
Strategies
     Level of content storage (granularity/ structure)
         File level – A logical document may have several physical
          components – naming and storage handling is a key issue
         Structured representation – document hierarchy (e.g. XML)
         Record level – stored as database records or occasionally as
          individual files (e.g. staff directory, customer profile)
     Document identification
         URL
         Unique? Persistent?
         Emerging standards/ best practices: DOI, OpenURL


                                                            T.B. Rajashekar

Content Storage and Processing:
Strategies…

   Presentation/ delivery of content
       Record level content – no issues
       File level content – may need to be split into
        smaller units to facilitate faster delivery,
        audio/video streaming, PDF page serving,
        compression
       Hierarchical document browsing

  Resource Discovery: Issues

How do we let users know what sources can be
                 accessed?
    How do they access these? (Interface)
     How do we support personalization?
How do we provide single point access to digital
                  material?
 What inventory and finding aids are relevant?

Resource Discovery: Strategies…
   Structured search (metadata-driven)
   Object search (full-text, multi-media object
    search)
       Search at finer granularity (tables, figures,
        paragraphs, section headings…)
   Global search and resource type search (e.g.
    bib db, e-journals, reports, experts)
   Structured presentation (display)

Resource Discovery: Strategies…
   Hierarchical browsing (subject schemes/ topic
    directory)
   Relevance ranking, QBE, hit/link – based
    ranking
   Related sources found useful by others (e.g.
    Amazon.com)

Resource Discovery: Strategies…
   User rating and comments on accessed resources
    (e.g. Amazon.com)
   User interface: Design for productivity, efficiency and
    memorability
       Intranet users are repeat users and use DIS as a
        productivity tool
   Search refinement, search history, search set
    combination

Resource Discovery: Strategies…
   Personalization
       Most users use only a small number of resources
       Allow them to set up a profile of preferred sources
        (and modify the profile when needed)
       These become the default menu picks when they
        visit next time
       User profiles can also be used for “push” based
        delivery of content
       Support for monitoring of content changes in
        remote sites (e.g. Netmind)

 Usage Monitoring: Issues

How do we know what digital sources are
      being used (and not used)?
             How much?
              By whom?
    How is our system performing?
 How do we evaluate digital information
               services?

Usage Monitoring: Strategies
   Usage monitoring
       Trapping of link clicks through re-direction (static or dynamic
        pages)
       Access pattern: browse, search, both, how long?
       Query trapping – and associating with used sources and
        users
       Analysis – by source, user (what queries, how many hits,
        what sources)
       Linked to de-selection, promotion/ orientation, license
        renewals…
   DL evaluation and performance issues – only now
    being addressed

Preservation and Maintenance:
Strategies
     Content and link currency
     Content refreshment plan
         3-5 years
         Formats
              TIFF (scanned pages)
              PDF (scanned pages, WYSIWYG e-documents)
              XML – Long term preservation
         Monitoring of content due for refreshment
         Maintenance of support tools for refreshing and reading
          software
     Microfilm back-up, print back-up???

Networking and Interoperability: Issues

    How do we network with other similar
                     services?
    How do we federate access to different
   collections within and across enterprises?
 How different digital information services inter-
 operate, exchange information and help users
               to find information?

Networking and Interoperability:
Strategies

     EDIS should use relevant standards wherever
      possible
     Ensures improved preservation,
      interoperability and resource sharing
     Metadata – key for networking & sharing
     Standards exist at several levels, including:
         Content: metadata (DC, MARC), source (XML…)
         Cross searching: OAI
         Linking and persistence: DOI
