We both demoed some forward-thinking work in the area of photos. Prabhkar Raghavan of Yahoo! showed a dynamic timeline of photo and tag bursts. Images and their respective tags scrolled across the screen as days incremented indicating bursts of activity from the community as they upload bits of their lives over time, providing an historical view of primary source information in a very interesting way. Google's Alan Eustice showed how they are now scanning faces in images to identify characteristics such as male or female. They then demonstrated how a face could become a search criteria which then pulls up results of other photos where this face also appears...amazing if not a little scary.
One company is building tools that reflect how people are expressing themselves. The other is building tools that will help find needles in haystacks. One is facilitating community development. The other is facilitating data retrieval.
