• You have a virtual sensor at home providing data on humidity (H) and temperature (T) at regular intervals (SENSE)
• Your local intelligence is the following (THINK)
• if H>HTh and T>TTh switch on the virtual air conditioning (ACT)
• Notice that the thresholds HTh and TTh are initially set to arbitrary values 
• In the meanwhile you have a server running sentiment analysis to verify whether people  is actually confortable by the given thresholds
• if sentiment positive then nothing
• if AVERAGE sentiment negative then send a command over the Internet to your sensor at home to decrease HTh and TTh
• For the sake of simplicity run sentiment analysis on the word "temperature"
