37. Use case – Antiques Interactive
Bert and Anne
www.linkedtv.eu
“I like to relax and sit back when I
watch Antiques Road Show. It’s
always exciting when something’s
worth a lot. In some cases, I like to
look up extra info about an object or
art style after the show on the PC,
but if something doesn’t interest me,
I’ll just read a magazine.”
“As an antiques shop owner, by work is
also my hobby. I’m always looking up
information about art objects on my PC
or tablet. I like watching my colleagues
talking about are on Antiques Road Show
and I use my tablet to bookmark specific
objects or other information that I like. I
also do this for Anne, and send her
overviews.”

Broadcasters want to have some control over noisy data.
Editors have the expertise to determine relevance +
The user interface can only show a limited amount of links, and there are many

Research: sample 805 videos, average 55 NEs per video. 55 NEs = many, many

56. Future work in LinkedTV
www.linkedtv.eu
The project ends in May 2015. The coming year, we’ll focus on:
•Improving noisy data from automatic enrichments
•
eg. through aggregating multiple entities and visual cues
•Multiple user studies and iterative development of front-end
functionalities and interface based on feedback
•Making enrichments more relevant for users by further refining
personalisation technologies
•Further Market studies and business model development
