“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 tasksand 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


Content navigation as an exploratory process

Relevance is informed by the user and patterns of use

I bring… Expectations

Relevance signals



Relevance is perceived based on the user’s task

I … Complete a task Transact business Look for something specific Read generally Explore a subject See what’s new/newsworthy Play


I want to dig deeper into this…

Surprise me!

Given this, I also need to

look at…

This isn’t what I’m looking for…

I’m done…now what?

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.
