how much do we know about how users will take up and interact with semantic web
technologies?

overview
→ deployment of Semantic Web technologies at ESWC2006
→ evaluation: delegates’ experiences of these technologies
→ user interaction and uptake challenges
User Interaction and Uptake Challenges to Successfully Deploying Semantic Web Technologies

deployment of semantic web technologies at ESWC2006
• aims– enhance the conference experience– showcase the state of the art– allow us to eat our own dog food
=> stimulate future research

User Interaction and Uptake Challenges to Successfully Deploying Semantic Web Technologies
Tom Heath, John Domingue, Paul Shabajee10
deployment of semantic web technologies at ESWC2006
• pre-generated semantic descriptions
• annotation tools(e.g. semantic wiki, photo annotation application)
• tools that could use the annotations(e.g. semantic search engine, semantic browser/desktop)

evaluation of ESWC2006 technologies
• aim– capture experiences and impressions of the
technologies from the user’s perspective
• method– online questionnaire, scaled and free response
questions– 48 (voluntary) responses (16% of delegates)– qualitative (thematic) analysis

7 user interaction and uptake challenges
to successfully deploying
semantic web technologies

1. increased awareness
• people need to know about it to use it (!)
• may encourage more people to take a look…
• …but is not enough by itself

2. clearer benefits
• describe functionality in terms of benefits not technology…
• …even for the semantic web community!
• how do we convey clear benefits of semantic web technologies to a lay audience(without having to explain the semantic web)?

3. appropriate functionality
• give the people what they want
• did the applications meet clearly defined and well evidenced user needs?
• are wishlists and motivating scenarios adequate and appropriate?

4. guidance to users
• provide more hand-holding for novel functionality
• which mental models can people use to understand novel functionality?
• how do we support users in developing new mental models?

5. improved usability
• attend to basic usability needs
• does existing usability literature provide sufficient guidance on designing usable semantic web experiences?

6. coherence
• ensure a coherent user experience
• …in use and reuse of data
• …in the navigation experience

7. critical mass of participation
• understand how to reach critical mass
• not limited to ‘social’ applications
• need to take guidance from generic literature

Tom Heath, John Domingue, Paul Shabajee23
• generalisability of the findings• non-systematic sampling• can’t claim generality
– but…• some commonality with existing models• if we have these problems, then…
• further evaluations required
