Summarizing
The peculiarities of the SMGI data model enables the analyst to perform a novel analytics on S-T-U/P multimedia data:
Spatial analysis of user interests;
Temporal analysis of user interests;
Spatial Statistics of user preferences;
Multimedia content analysis on texts ( and images, video, or audio tbc);
User behavioral analysis;
OR
a combination of two or more of the previous such as in
Spatial-Temporal Textual Analysis (STTx)

Conclusions
Is SM-GI useful to strategic response planning and management?
real time data collection about: facts + behaviors + perceptions
(+preferences + needs..) pluralism & participation
exploratory multiscale analysis
different combination of sources in different locations
issue of data accessibility
