Introduction
DinoFun World held a series of events about Scott Jones, an internationally renowned football star in last year. Scott was planned to appear in two stage shows each on Friday, Saturday, and Sunday to talk about his life and career, as well as a show of memorabilia in the park’s Pavilion (Area 32). However, the event was marred. Although the crimes were rapidly solved, they have intention to know to how to do better preparation in the future. The task is understanding how people move and communicate in the park, as well as how patterns changes and evolve over time, and what can be understood about motivations for changing patterns.
IDs that Stand Out for Their Large Volumes of Communication
The 2 IDs that stand out for their large volumes of communication are 1278894 and 839736, separately.
As shown in the right picture, ID 1278894 sends and receives messages at regular intervals for a period by observing the dots on blue lines are relatively sparse and the interval is fixed.
The ID 839736 communicates unregularly. Because dots on the orange line are close and form a line. It is continuous.
Who is the criminal?
Data Filter
- Incident’s Time
Our main task is to identify the criminal offenders. So the first step is to filter data to narrow the range. If we want to filter data, we should identify time of the incident.
As shown in the graph above, there were 2 peaks in Friday and Saturday, with the same time and location. Through this, we could conclude that the 2 stage shows in everyday are at 11:00 AM and 4:00 PM, respectively. In addition, the performance venue was located in Coaster Alley. But in Sunday, numbers of communication increased sharply at 11:39 AM after the 11:00 AM peak occurred, and the location is Wet Land where the exit of Creighton Pavilion was located at. It shows people found the Pavilion was vandalized before 11:39 AM on Sunday.
