As we migrate from document-centric to subject-centric computing, we are discovering new approaches to the online facilitation of collective sensemaking. Our approach is to federate with a central topic map the many different tools of hypermedia discourse, such as social bookmarking, semantic annotation, and dialogue mapping. We are learning that this federation facility provides opportunities for unique uses of aggregated sensemaking. We report on our progress in the development of a dashboard facility as one such opportunity.

5. From Documents To Subjects CALO My Subjects

6. Subject-Centric Collaboration with CALO Groups of CALO Users share and evolve subjects they harvest CALO My Subjects CALO My Subjects CALO My Subjects CALO My Subjects CALO My Subjects Knowledge Garden Our Subjects

10. Example OpEd Document Food Crisis Related to Competing Uses of Crops

11. Issue Map of OpEd Made with Compendium

12. Key Node in the Issue Map And Entailed Subjects Subjects related to production of crops that feed beef Many subjects are found in every document, every story. A task for CALO is to facilitate capturing and representing those subjects and their relationships. A later task is reminding with the Dashboard.

20. Knowledge Maps as Collective Memory A Topic Map lies above information resources (documents) and weaves that information into a fabric made of subjects and their relationships that serves as a collective memory Source: Steve Pepper

21. Gardening with Tagomizer A User asserts a Tag on a Resource A tag is a reminder that associates the resource with CALO projects, or subjects, relationships, or other ideas mentioned in the resource “ Semantic Desktop”

22. Tagging and Annotating Bookmarking with Tagomizer facilitates Tagging and Annotating. An annotation is fully addressable, editable, and can be tagged or annotated.

23. Gardening By Connecting A User asserts a relationship between ideas expressed at two different resources Semantic Desktop concept “ is exemplified by ” OpenIris.org

24. Connecting with Cohere

25. Gardening through Dialogue Users Ask and Answer Questions, and Discuss the Answers Compendium Screenshot
