Cluster 4, the largest cluster, contains 32.48% session records;
cluster 2 contains 26.11% session records; cluster 5 contains
15.92% session records. Based on the observed means and proportions
of characteristic, cluster 4 can be labelled as ‘‘Blood pressure
management user’’, which enables provisional identification of
cluster 4 as the more ‘‘typical’’ cluster. The Blood pressure management
functions trigger cluster 4 elders at a rate thousands of times
greater than other clustering users. The same is true for the Query
weather forecast. The cluster 2 can be labelled ‘‘Entertainment
user’’. The game functions are requested at a much higher rate
by Entertainment users compared to other clustering users. The
cluster 5 users can be labelled ‘‘Health users’’. The BMI, Diet, Exercise,
and Blood pressure functions were requested at a much higher
rate by Health users than by other clustering users. The Diet
management functions trigger Health users, and the contiguous
self-care sequence is exercise management, Blood pressure management
and BMI management.
