Communication Patterns
As can be observed from the chart on the left, there are two particular IDs, “839736” and “1278894”, which consistently sent out abnormally high volume of communications throughout the three days.
Outliers
Two patterns which can be observed from the chart on the left are that communication from “1278894” only occur in specific time period of the day while “839736” has a significantly lesser volume but consistent communication throughout the day. The volume of communications from "1278894" is also substantially higher than that from "839736".
ID 1278894
The communication from the source ID “1278894” was sent exclusively from the Entry Corridor of the theme park. In addition, the communication was sent in a regular timeframe in each day, from 12.00pm to 12.55pm, 2.00pm to 2.55pm, 4.00pm to 4.55pm, 6.00pm to 6.55pm and 8.00pm to 8.55pm. Each communication from this ID is sent at a regular time interval of 5-minute.
ID 839736
Similar to the communication from ID “1278894”, the communication from ID “839736” originated only from the Entry Corridor. It can be observed that the communication from this source was sent almost continuously throughout the operating hours of the theme park. The volume of communication sent out was consistent across the whole day for both Friday and Saturday, however, on Sunday it can be noted that that is a huge spike in volume of communication sent out by this source at approximately 11.40am and subsided at approximately 12.30pm. Another minor spike in volume of communication sent was observed at approximately 2.40pm on Sunday and lasted about 20 minutes.
Network Graph of ID 1278894 & ID 839736
| ID | Degree | Degree Rank |
|---|---|---|
| 1278894 | 38658 | 1 |
| 839736 | 5914 | 2 |
| 1196426 | 64 | 3 |
Analysing the network graph plot of the communication originating from the two sources indicates that the two sources have a huge network of communication with almost all the distinct IDs source. The degree of connection table above indicates that both ID 1278894 and ID 839736 have significantly high degree value relative to the next closest ranked originating source, this indicates that these two IDs has much more connections than the rest of the source IDs in terms of communication origin.
Hypothesis
- Judging from the frequency of communication of the ID 1278894 and the volume of communication sent, it can be hypothesized that this communication source is probably a regular public broadcast announcement for shows or activities at a certain time period in the theme park.
- It can also be hypothesized that ID 839736 is a public announcement source as it is sent to almost all the records and is consistently occurring throughout the day.
Communication From All with exclusion of ID 1278894 & ID 839736
Abnormality in Communication Volume on Sunday
Examining the breakdown of the communication patterns on Saturday and Sunday revealed that there are two spikes in volume of message sent on Saturday and Sunday. On Saturday it is for a single moment at 4pm. However on Sunday, from approximately 11.35am to about 12.20pm, there was a sustained increased in communications sent. The single spike in communication at 4pm could also be observed on Friday, hence this spike in volume of communication sent on Saturday does not seem to be out of the norm.
Communication to External on all three days
Communication to external was fairly constant throughout all three days, however there is a spike in communication sent from the visitors in the theme park to external from approximately 11.41am till 12pm.
