Contexts and Perspectives
Contexts and perspectives in which information objects are:
§ Created
§ Collected/ deposited
§ Described § by creators § by collectors§ by potential users§ over time§ across cultures/languages§ across professions§ relative to the volume of similar objects in a collection
Discovered/used

What’s in a name?
Knowledge & Library Services (KLS @ HBS)
§ Baker Library Services§ Contemporary collections research, reference, access
§ Historical Collections§ Reference and access services to the world’s largest business history collection
§ Web & Intranet Services§ Web service management for HBS
§ Knowledge & Information Assets Management§ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Knowledge & Information Assets Management KIA was Collections Management was Library Technical Services
Three Units-
§ Taxonomy & Metadata Management§ grew from Cataloging§ provides metadata and taxonomy management and consulting services to HBS
§ Content Management § grew from Acquisitions & Serials Management§ responsible for acquisition and management of purchased or licensed content
§ Information Lifecycle Management§ grew from Records Management§ responsible for management of internally created content from its creation to
destruction or transfer to permanent archival storage
![Page 6: In other words...: Using multiple taxonimies](https://reader033.vdocuments.net/reader033/viewer/2022060109/5557836fd8b42aa3378b462e/html5/thumbnails/6.jpg)
Shift in core products and services
§ More information to manage, but less of it in physical formats
§ More competition from vendors for cataloging, processing, access…
§ Increased demand for metadata and taxonomy management to meet
business needs specific to HBS
§ Voluminous increase in internally created digital information§ Faculty publications and administrative records, documents, and documentation§ Databases, wikis, i-sites, spreadsheets, websites, photographs, videos, podcasts,
weblogs, Second Life sessions, Facebook groups…

Changed customer service models
Just in case - Libraries attempt to anticipate information needs buy
acquiring what customers might need
Just in time – Libraries get the information when it is needed (resource
sharing)
Just for you – “I want the information that I need delivered to my desktop
when I need it!” (RSS feeds, purchase on demand, improved discovery
tools)

Definitions
§ Controlled vocabulary = list of terms explicitly enumerated, controlled
and published by a registration authority
§ Taxonomy = controlled vocabulary terms hierarchically structured with at
least one parent-child relationship to other terms in the structure
§ Thesaurus = networked collection of controlled vocabulary terms with
related or equivalent terms.

Perspective -
Perspective
§ the appearance of things relative to one another as determined by their
distance from the viewer wordnet.princeton.edu/perl/webwn
§ the interrelation in which a subject or its parts are mentally viewed ; point
of view cte.jhu.edu/techacademy/fellows/Hemmingson/webquest/slsdictionary_htlm.htm
§ the process of viewing something from a distinct vantage point; or, the
impression one has of an object or landscape from particular vantage

1967: AACR first published; OCLC founded

Perspective (Access)
1975 - Periodicals Rooms with hundreds of volumes of print
index/abstract/citation services – each with its own taxonomy
1985 - DIALOG – sequential searches of online serials information using
terms from dozens of paper thesauri with distinct vocabularies
Today – free-range, full-text searching across platforms, BUT!

An example-
1. In the West, ALL Swans were white
until 1697.
2. highly improbable and unpredictable
events can have massive impact
3. Humans attempt to create order
where there is chaos or to impose
order where there is none
4. Predicting the future is more complex
than analyzing what we know of the
past.

Say what? Say how? Says who?
§ User terms (web analytics)
§ Cross-mapped thesauri – shared input§ Bombay = Mumbai=map coordinates=mail code=phone code§ Tradenames = generic§ English=French=Chinese=…
§ Corporate & Personal Name registries
§ Tag clouds and topic maps as finding aids
§ Cooperative tag binding

Stovepipes or silos vs. bridges and maps
§ KW search reveals only that which is explicitly stated within an object
§ Faceted searches against a single taxonomy can help or hinder
§ Metadata facilitates or protects/prevents/limits discovery§ Metadata embedded in objects§ Metadata stored in repositories with pointers to objects§ Digital Rights Management
§ Taxonomy helps narrow or broaden search within a structured hierarchy
§ Thesaurus widens search with inclusion of related/equivalent terms
§ Data Registries improve consistency

What next?
§ Smarter data-mining software§ Computational linguistics§ Entity extraction software
§ Cross-application tag aggregation§ Cooperative tag binding across platforms, professions…
§ Cooperative relationship and concept mapping§ For audience subsets§ By audience subsets
§ Attention metadata – ALL about individual user behavior
§ Perspective analysis and customized context = advanced personalization
