**6. Conclusion**

It is a smart behaviour for decision-makers to spend more time to realize the whole views of the problems and solutions before they make wise decisions. However, an effective decision analysis tool is hard to obtain. The XREAP software is an optional choice for assisting deci‐ sion-makers. As the tool results said, the SP service can be spread through SN, and it ex‐ plores and assists the potential subjects who present the trend of suicide ideation.
