Information-Enriched Workspaces Yunwen Ye Aspen Symposium
Introduction • Distributed cognition • Knowledge-intensive activities require knowledge from the user and the world • Easy access to external information is essential to the performance of such activities • Information-enriched workspaces • Immediate access to external information within the workspace
Articulating the queries Knowing the existence of information Applying the information Evaluating the information Information Repository System Workspace Current Model of Information Repository Systems
Information Display Information Repository Information-Enriched Workspace Information-Enriched Workspace (IEW) • Information acquisition as a part of work processes • Integration of acquiring and applying information
Design Principles for IEW (1/2) • Integration • Reducing the memory loss caused by context switch • Multiple communication channels • Explicit communication channel • Implicit communication channel • Layered information • Information discernment vs. detailed evaluation • Details on demand: progressive revelation of detailed information • ……
Design Principles for IEW (2/2) • Natural interface • Consistent operation style with working environments • Information delivery • Providing access to unknown information • Shared understanding of the larger context • Taking into consideration of larger context of current task • User-specific • Accommodating individual difference in knowledge
Component Repository Programmers Reuse Queries Listener Fetcher Retrieved Components Presenter An Example: CodeBroker Programming Environment reuse Reusable Components Information Display
Agent-based task-specific delivery • Interface agents for repository systems • Combining information access and information delivery • Invoking the component-locating process directly from the programming environment • Command style consistent with Emacs operations • Delivery of potentially reusable components based on programmer’s task • Modeling the task based on comments and signatures
Component Repository Programmers Reuse Queries Listener Fetcher Retrieved Components Presenter Agent-based task-specific delivery Concept: Create a random number between two limits Constraint: int <- int x int Programming Environment reuse Reusable Components Information Display
Remove uninterested packages or classes Shared Larger Context • By specifying the high-level goal • By incremental discourse modeling to capture the (un)interested information Specifying (un)interested packages or classes
User-specific • Removing known components from the information display based on user models • Adaptable and adaptive user modeling Add java.awt.CardLayout to the user model Add java.util.Vector.addElement to the user model
Layered Information • Short description in the information display (name and synopsis) • Mouse-sensitive information (signatures and matching keywords) • Detailed information in an external browser • Example programs • Links to experts Example programs
