Short Bio: Anthony Jameson is a principal researcher at DFKI, the German Research Center for Artificial Intelligence, where he heads the Choosability research unit, which synthesizes and exploits knowledge about human choice and decision making in the design and study of (intelligent) interactive systems. He is the author of the chapter Choices and Decisions of Computer Users in the 2012 edition of the Human-Computer Interaction Handbook and founding coeditor-in-chief (with John Riedl) of the ACM Transactions on Interactive Intelligent Systems.

Title: How Can We Support Multifocal Exploration of Semantic Data?

---

Abstract: Interaction designs for the exploration of semantic data (and, more generally of other types of content on the web) tend to presuppose that users (as is normally necessary in the physical world) will be pursuing one line of exploration at a time, backtracking or restarting when they want to switch to a different line of exploration. This talk will address the following questions:

1. What types of task exist where users can benefit from being able to explore along multiple lines in parallel, as in computational search strategies like best-first search and beam search?
2. Why is multifocal exploration generally difficult with current systems?
3. What new interaction designs can better support multifocal exploration?
4. How can these forms of interaction be enhanced with intelligent techniques (e.g., for summarization or recommendation)?

I will present concrete instantiations of some of these ideas from ongoing work in the projects GLOCAL and EventMAP.
