7 Conclusions

In this paper, system recommending images for alleviating loneliness in compliance
of situation after recognizing loneliness of the aged with modeling loneliness status of
the aged and using ratiocination technology was introduced.
There can be various situations in which the aged feel loneliness but in this system,
it was judged largely by three cases of lonely situation. As this is an initial and
primary demo system, the number of cases is few and simplified but it needs to be
