Dogear: Social bookmarking in the enterprise

We describe a social bookmarking service de-signed for a large enterprise. We discuss design principles addressing online identity, privacy, information discovery (including search and pivot browsing), and service extensi-bility based on a web-friendly architectural style. In addi-tion we describe the key design features of our implementa-tion. We provide the results of an eight week field trial of this enterprise social bookmarking service, including a de-scription of user activities, based on log file analysis. We share the results of a user survey focused on the benefits of the service. The feedback from the user trial, comprising survey results, log file analysis and informal communica-tions, is quite positive and suggests several promising en-hancements to the service. Finally, we discuss potential extension and integration of social bookmarking services with other corporate collaborative applications.

Social Bookmarking in the Enterprise

One of the greatest challenges facing people who use large information spaces is to remember and retrieve items that they have previously found and thought to be interesting. One approach to this problem is to allow individuals to save particular search strings to re-create the search in the future. Another approach has been to allow people to create personal collections of material. Collections of citations can be created manually by readers or through execution of (and alerting to) a saved search.

Designing remail: reinventing the email client through innovation and integration

The Remail design team defined a specification for an innovative and integrated email client. This design-lead effort tackled three key problems that email researchers have discovered: lack of context, co-opting of email, and keeping track of too many things. Based on earlier design and research explorations, we conceived of a client from the ground up that attacked these problems in an integrated fashion. Our solutions were based on three constructs: showing message context, marking email, and selective display. A small team of programmers implemented much of the design in a functional prototype. This experimental client continues to allow researchers to expand and explore these concepts.

Chat spaces

Chat Spaces are rich persistent chats that provide light-weight shared workspaces for small to medium-scale group activities. Chat Spaces can accommodate brief, informal interactions (similar to Instant Messaging), and can also support longer-term complex threaded conversations including large numbers of people and shared resources. Our design maps a hierarchical thread representation onto a time-ordered two-column user interface. This mapping allows a user to follow the global dynamics of the entire thread in the chronological column on the left while being able to participate in a selected topical branch in a second column on the right. We also present a dynamic thread map that provides an overview of the entire conversation and supports quick navigation of topical branches in the thread.

TagOrbitals: a tag index visualization

With the rise of web-based tagging systems, it has become important to help users search and browse the index of tags that are being created. One promising approach is visualization, but existing techniques rely on hard-to-interpret network diagrams or focus only on a small subset of a collection. This sketch introduces TagOrbitals, a technique that can display an entire index at once, while simultaneously showing details of individual tags and items.
