Use case – Antiques InteractiveBert and Anne

“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 possible links depending on the size of the white list [Li et al., 2013]

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
