“Relevant” content is in the eye of the beholder – users –
associated with their goals.
In UX design, mental modeling and user research help assess
expectations, providing context for semantic application design.
Why am I
seeing this?

Challenges we look for
• User response to links
• Signal problems
• Weak signals
• Signal density
• Signal switching
• Result density
• Clue misalignment

User response to links
Invitations
to stop
reading
Great
distance
between
purpose and
substance

User response to links
Links are often a distraction,
digression or diversion.
If it’s important, it should be available
without undue navigation.
Consider where to:
 Link
 Summarize
 Incorporate

Signal challenges
Weak signals
 Not enough context parameters to know what “relevant” means
 Either not enough metadata in content, or not enough in usage
Signal density
 Too many attributes without sufficient value identification
• Auto-tagging (“semantic annotation”) without curation
• Ambiguous content – it’s about too many things
• Sources of user signals too diffuse

Signal challenges
Signal switching
 Stale signals
• Signal lifecycles: Firefly or tortoise?
 Multi-tasking or task-switching
• Moved on to next task, interrupted temporarily
• Multi-dimensional evolving situation
• Japan – Earthquake, Tsunami, Nuclear risk
• Firefighters – Blaze, Medical needs, Gas/chemical risk
 Out of context – e.g. making dinner reservations while at the office

Other challenges
Result density
 Too many possible “related” items, without clear ranking/weighting
• Big events
• Big content stores or broadly federated content
Clue misalignment
 Link names do not align with purpose, creating confusion
 Setting expectations with the user

Relevance signals

Relevance models are informed by content structure
Their experience
and motivations
Their tasks
and questions
Their situation
or context
Relevance models are also informed by knowing your users
Content
relationships and
“about-ness”
Don’t
guess!

Relevance signals
• Content
• User & usage
• Task & domain
• Situation

 Transact business
 Look for something specific
 Read generally
 Explore a subject
 See what’s new/newsworthy
 Play

Reflecting task, user and content relevance

Goal: embed in application

User control in task
The increase in OA-related musculoskeletal pain especially in
the growing elderly population has created heightened interest
in effective treatments with better safety profiles. The
Glucosamine/chondroitin Arthritis Intervention Trial (GAIT) was
designed to examine the effects of the dietary supplements
glucosamine and chondroitin sulfate given alone or in
combination as compared to celeecox or placebo on pain
associated with osteoarthritis of the knee. The primary
symptomatic outcome assessment of the GAIT study was after
24 weeks of randomized, double-blinded, placebo-controlled
therapy.[6] An ancillary structural study describing the effects of
the agents on radiographic joint space width loss for up to two
years has also recently been reported.[7] To date, very few data
have been reported for the long-term treatment of OA with any
agent including the supplements and celecoxib studied here.
Patients in the structural study continued to have safety and
clinical efficacy assessments at all scheduled visits. This paper
details the clinical efficacy and safety experience with these
agents alone and in combination along with celecoxib as
compared to placebo in patients from this subset of GAIT over
24 months of follow-up.
