is done by the system merely by the participation of the user in these groups and no explicit action by the user is required this is similar to the corporate setting where a user can be grouped with his or her peers or where a user can be grouped with all other employees with offices on the same floor in a building additionally the system can take advantage of dynamic groups created for projects spanning employees in the corporate hierarchy the members of these dynamically created groups would also move closer to the u201c locus of relevance u201d of the user these groups could have been created explicitly in the corporate database or the system may interface with external applications such as a mailing list in an email application in order to discover these dynamic groups once a dynamically created group is detected again using the techniques described above the relevance weights of the members of that group can be adjusted such that group members are returned higher in the result set overriding the default corporate hierarchy for example after a new emailing list for a project is created the relevance weights of the members of that project can be adjusted and the results would be ordered to return project members then peers then subordinates then supervisors and finally persons unrelated to the user in the corporate hierarchy automatic adjustment of locus or circle of relevance would also be applied in a transitive manner between individuals or groups of individuals.
