In practical terms: Metadata helps users locate, navigate, interpret content Metadata helps organizations manage content Metadata helps systems manipulate content

Related Concepts & Uses Taxonomies
Anything organized in some sort of hierarchical structure
Tagging Adding almost any kind of metadata to content, but now
often descriptive and user-provided
Thesauri Focus on relations between terms Focus on “concepts”
Ontologies Usually model a specific domain or part of the world Generally machine-readable
Increasing complexity and richness
iSchool
Goals for Search Sessions Understand the basic issues in information
retrieval (searching primarily unstructured text)(e.g. words vs. concepts, word problems, recall and precision)
Know the techniques generally used by modern search engines (vector space model, term weighting)
Learn how search engines can be used most effectively in information architecture (e.g. configuring search, integrating search and browsing, tricks like “best bets”)
iSchool
What we control (the IA part)? Requirements and search engine selection
Developing search requirements Build vs. buy Vendor evaluation/selection Consultants?
Content selection What to search/zones/etc. Tags
Search engine configuration Zones, what gets indexed, sometimes how Number of results, sometimes recall vs. precision Others (very often interface-related)
Interfaces
iSchool

Trends in the industry Increasing complexity Consolidation Interoperability (e.g., objects, XML)
Key IA software tools Back-end databases Content management systems Portals “Middleware” Personalization, other utilities
iSchool
Business Issues (Early On) Many mentioned already (e.g., politics, enlisting
Making the business case: ROI vs. “Columbus and the New World” Budgets and total cost of ownership “Buy in”
Defining the strategy Align actions with business goals Show examples Iterate, and involve users
iSchool
Business Issues (What Goes Wrong)
We’re late, and we’re over budget – why? Overly optimistic projections Done in by the vendor/consultant sales team Client doesn’t supply needed input Can’t find the right people (“mythical person month”)
Nothing seems to work – why?
Other vendor/people issues
It looks great to me, but the client doesn’t agree Requirements creep Management changes Business changes
iSchool
Ground rules for exam
What can be on it Anything that’s “really” covered, not passing mention Focus on concepts, but can include definitions,
examples
Style of exam As objective as possible Mostly multiple choice, some matches, short answers Designed to fit in < 1.5 hours
Degree of difficulty and grading
Prepare, but try to make the most of it and enjoy!
