Resolving Information Conflict Keep “better” tuple and discard the other There are many possible methods of conflict resolution Recently published tuple More trustworthy tuple Specific source’s identity Type of source: ‘reported current’, ‘measured device information’, ‘measured by sensors’, ‘reported scheduled’ Value of another element in tuple, such as ‘idle’ or ‘sphere’ In some cases, the conflict is better NOT resolved Keep both tuples intact and let the watcher choose Keep all values and list them all during tuple merging Possibly the best choice for ‘mood’ and ‘activities’ |
