Digital Stickers

  • Ontology of the university research group (OWLFile)
  • Ontology TreeView visualization (using prefuse)

  • TreeView of the above OWL file(treeview applet)

  • Qualitative group characteristic

        Faculty and Post-doc: KSChoi and ICMoon is overloaded.
        Students: no significant work relations among the students
        Staff: requires more interactions with the research group

  • Agent Interaction mechanism
        Calculate the utility of the new cooperation relation “workWith”
        The utility is based on the personal ontology of the two possible interaction partners.
        Benefit: the congruence (a better alignment) of people, work, and resources
           Person A is assigned to Work B requiring Resource C, and the Person A already has the Resource C
        (good case)
        Cost: the expansion of the personal ontology
           Person A needs to consider a part of Person B’s personal ontology as well as new relation
           “Person A workWith Person B”

  • Experimental result

        We tested the given group ontology (the above owl) to find more “workWith” relations resulting in better
        utility. We found 16 new relations.
  • Figure 10: The selected (max) utility from a relation and the average utility of the all possible relations.
    Table 3: The 16 selected relations to be recommended, and the relations’ utilities. We can identify which new relations are important and how much.

    The above new relations are the new recommendation to facilitate the cooperation as well as to avoid any further cognitive over loading.

  • An application of this agent interaction mechanism: Digital-Post IT
        The digital post-it recommends “workWith” relations among people in the group.
        However, this recommendation should be realistic: avoiding a new relation with a cognitively overloaded
        person and establishing new relations with an under-utilized person.
        To support this “workWith” recommendation, this agent interaction mechanism is used.
