I attended the webinar and this technology is amazing, fast, and available right now.

You can perform queries to get information like this from the db: "Find a meetings that happened in July within 5 miles of Berkeley that was attended by the most important person in Jans' friends and friends of friends."

In code, the above is:

(select (?x)

  (ego-group !person:jans knows ?group 2)

  (actor-centrality-members ?group knows ?x ?num)

  (q ?event !fr:actor ?x)

  (qs ?event !rdf:type !fr:Meeting)

  (interval-during ?event "2009-07-01" "2009-07-25")

  (geo-box-around !geoname:Berkeley ?event 5 miles)

!)
